Answer:
wave speed =344.1 m/s
using v=fΠ
where v is the speed
The wave speed will be 344.1 m/sec. The wave speed is found as the product of the wavelength and the frequency of the wave.
What is wavelength?The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
The given data in the problem is;
v is the speed = ?
f is the frequency= 370 Hz
λ is the wavelength of the wave=0.96 m
The relationship between the wave's wavelength, frequency, and speed is given as;
wavelength = speed of wave / frequency
[tex]\rm \lambda = \frac{v}{f} \\\\ v = \lambda \times f \\\\ v = 0.93 \times 370 \ Hz \\\\ v= 344.1 \ m/sec[/tex]
Hence, the wave speed will be 344.1 m/sec.

The MSDS for chloroform indicates that it is a clear liquid that has a pleasant smell and substantial vapor pressure. People should avoid inhaling its vapors, and it is sensitive to light. Malik needs 10 mls of chloroform for an experiment.
According to this information, how should he safely pour the chloroform?
He should locate the chloroform stored in a transparent container in chemical storage and pour directly into his beaker from that location.
He should locate the chloroform stored in a transparent container in chemical storage and should take it to the fume hood to pour.
He should locate the chloroform stored in a dark container in chemical storage and should take it to the fume hood to pour.
He should locate the chloroform stored in a dark container in chemical storage and pour directly into his beaker from that location.
Answer:
The correct option is the third option
Explanation:
Firstly, it must be noted that chemicals/reagents that are sensitive to sunlight are stored in dark/amber container in the laboratory. Hence, the chloroform can only be found in an amber/dark bottle.
Also, reagents/chemicals that release poisonous/offensive gases are handled in the fume cupboard in the laboratory. Thus, If Malik is going to pour the chloroform, he should pour it in a fume cupboard to avoid inhaling it because of the toxicity of it's vapor.
From the above explanation, it can be deduced that Malik should locate the chloroform stored in a dark container in chemical storage and should take it to the fume hood to pour.
Answer:
He should locate the chloroform stored in a dark container in chemical storage and should take it to the fume hood to pour.

Part of my other question!
I cant see the numbers but to find them heres an example 17 n would be at the top next to 15 and 20 if there on there and them you find the other number 105 w I think would be on the left then draw a straight line till they touch and wherever it is will be you answer and if you need further help search it up on here or google
Explanation:
ok so start on the latitude which is the lines that go left to right. it would be the first number in the parentheses.(latitude,longitude) so if the number is 17°North you would look on the right side of the map and find 17°N. It might show y 15°N so you have to try and find where you think 17°N would be. place you finger where you think 17°N is. then find 105°West which is longitude and is the lines that go up and down. and drag you fingers together in a straight line until they both meet and that is where the awnser is.

A go kart is traveling at a constant 13.8 meters per second around a horizontal circular track with a radius of 42.0 meters. The Combined mass of a go kart and the driver is 143 kg. What is the magnitude of the centripetal force acting on the combined mass
Answer:
648.40N
Explanation:
Centripetal acceleration is the acceleration of an object around a circular path. Centripetal for e acting on the combined mass is expressed as:
F = ma
F = mv²/r
m is the mass of the object = 143kg
v is the linear velocity = 13.8m/s
r is the radius = 42.0m
Substitute the given parameters into the formula;
F = 143*13.8²/42
F = 27,232.92/42
F = 648.40N
Hence the magnitude of the centripetal force acting on the combined mass is 648.40N
A cannonball with a mass of 50 kilograms and a golf ball with a mass of 0. 8 kilograms are dropped in a vacuum from a height of 10 meters. Compare the acceleration of each object as they fall.
It's gonna take a huge amount of time and effort, and we're gonna spend a huge amount of money, to build a vacuum chamber big enough to do this experiment.
So when we're finally ready to try it, the cannonball and golf ball will make a kind of cute experiment, but let's make it really interesting. Let's ALSO try it with a feather, an apple, a watermelon, a tennis ball, a basketball, a coffeepot, a chair, an old computer, a set of dishes, a trombone, a bicycle, a math book, a TV set, a gallon of milk, a skateboard, a shotgun, a concrete block, a car, a waterbed, a schoolbus, a battleship, your dog, and my wife !
Drop every single one of them from a height of 10 meters.
Every single one of them accelerates at 9.8 m/s² as it falls, takes 1.429 seconds to reach the floor, and hits the floor at a speed of 14 m/s. The feather, the schoolbus, and my wife stay together all the way down.
The only way this doesn't happen is if ...
-- you do this experiment in some other place that's not Earth, or
-- you throw one of the objects and you don't just drop it, or
-- the vacuum chamber has a leak and some air gets into it.
Because that's how gravity works.
a 32kg object has a momentum of 480kg m/s northward. what is the objects velocity ?
Answer:
velocity = 15m/s
Explanation:
momentum of the object = 480kg/ms
nass of object = 32 kg
velocity of object = ?
momentum = velocity × mass
velocity = momentum / velocity
= 480kg/ms/32kg
= 15m/s
The level of toluene (a flammable hydrocarbon) in a storage tank may fluctuate between 10 and 400 cm from the top of the tank. since it is impossible to see inside the tank, an open-end manometer with water or mercury as the manometer fluid is to be used to determine the toluene level. one leg of the manometer is attached to the tank 500 cm from the top. a nitrogen blanket at atmospheric pressure is maintained over the tank contents. felder, richard m.; rousseau, ronald w.; bullard, lisa g.. elementary principles of chemical processes, 4th edition (page 81). wiley. kindle edition.
Complete Question
The complete question is shown on the first and second uploaded image
Answer:
When water is used the reading is [tex] R = 2281.6 \ cm [/tex]
When mercury is used the reading is [tex] R = 23.83 \ cm [/tex]
The best fluid to use is mercury because for water a slight change in toluene level will cause a large change in height .
Explanation:
From the question we are told that
The length of the leg of the manometer to the top of the tank is d = 500cm
The toluene level where in the tank where the height of the manometer fluid level in the open arm is equal to the height where the manometer is connected to the tank is h =150 cm
The manometer reading is R
Generally at the point where the height of the open arm is equal to the height of the of the point connected to the tank ,
The pressure at the height of the both arms of the manometer corresponding to the base of the tank are equal
i.e [tex]P_1 = P_2[/tex]
Here [tex]P_1[/tex] is the pressure of the manometer at the point corresponding to the base of the tank and this is mathematically represented as
[tex] P_{atm} + P_1 = P_{atm} + P_t[/tex]
Here [tex]P_t[/tex] is the pressure due to the toluene level in the tank and in the arm of the manometer connected to the tank and this is mathematically represented as
[tex]P_t = \rho_t * g * h_i[/tex]
Here
[tex]\rho_t [/tex] is the density of toluene with value [tex]\rho_t = 867 kg/m^3 [/tex]
[tex]h_i[/tex] is the height of the connected arm above the point equivalent to the base of the tank , this mathematically represented as
[tex]h_i = d - h + R[/tex]
and [tex] P_2 [/tex] is the the pressure at the open arm of the manometer at the point equivalent to the base of the base of the tank and this is mathematically represented as
[tex] P_2 = \rho_f * g * h_f [/tex]
Here
[tex]\rho_f[/tex] is the density of the fluid in use , if it is water the density is
[tex]\rho_w = 1000 \ kg /m^3 [/tex]
and if it is mercury the density is
[tex]\rho_m = 13600 \ kg /m^3 [/tex]
[tex]h_f[/tex] is the height of the fluid in the open arm of the manometer from the point equivalent to the base of the tank which is equivalent the manometer reading R
So when the fluid is water we have
[tex] P_{atm} + \rho_t* g *(d - h + R) = P_{atm} + \rho_f * g * h_f[/tex]
=> [tex] \rho_t* (d - h + R) = \rho_w * h_f[/tex]
=> [tex] 867 (500 - 150 + R) = 1000 * R [/tex]
=> [tex] R = 2281.6 \ cm [/tex]
So when the fluid is mercury we have
[tex] \rho_t* (d - h + R) = \rho_m * h_f[/tex]
=> [tex] 867 (500 - 150 + R) = 13600 * R [/tex]
=> [tex] R = 23.83 \ cm [/tex]
The difference in the mercury reading for mercury due to the fact that they have different densities as we have seen in this calculation
So the best fluid to use is mercury because for water a slight change in toluene level will cause a large change in height .
a phosphorus atom needs to gain ---electrons to achieve a full octet
Answer:
Three (3).
Explanation:
The octet rule is a rule in chemistry that states that, chemical elements would either gain or loss electrons in their outermost shell in order to attain a stable electronic configuration i.e having eight (8) valence electrons in their outermost shell such as chemical elements found in group 8 (2-8-8) known as noble gas.
A phosphorus atom needs to gain three (3) electrons to achieve a full octet because the atomic number of phosphorus is 15 and as such it has the electronic configuration of 2-8-5 and needs three electron in order to become a stable element.

An inclined plane of length 12m is used to pull a load of 3000N to height of 3m by applying an effort of 1000N. Calculate its MA, VR and efficiency. Also, find the work done in the machine
Answer:
MA = 4
VR = 3
e = 0.75 or 75%
work = 12000 [J]
Explanation:
The mechanical advantage in an inclined plane is defined as the relationship between the length of the inclined plane and the height of the plane with respect to the ground.
MA = L/h
MA = 12/3 = 4
Now the real advantage can be calculated as the relationship between the weight of the body and the force being applied.
VR = W/F
VR = 3000/1000
VR = 3
Efficiency can be calculated as the relationship between the real mechanical advantage over the ideal mechanical advantage.
e = VR/MA
e = 3/4
e = 0.75 or 75%
The work is defined as the product of the force by the distance, therefore we have:
work = F*d
work = 1000*12
work = 12000 [J]

an automobile was moving at 15m/s and accelerated at 2m/s^2 for 10s. what is the final speed
Answer:
35 m/s
Explanation:
Given that an automobile was moving at 15m/s and accelerated at 2m/s^2 for 10s. what is the final speed ?
The parameters given are :
initial velocity U = 15 m/s
Acceleration a = 2 m/s^2
Time taken = 10s
Using first equation of motion;
V = U + at
V = 15 + 2 * 10
V = 15 + 20
V = 35 m/s
Therefore, The final speed is 35 m/s
The final speed of automobile moving at the given initial speed and acceleration is 35m/s.
Given the data in the question;
Initial velocity of the automobile; [tex]u = 15m/s[/tex]Acceleration of the automobile; [tex]a = 2m/s^2[/tex]Time taken; [tex]t = 10s[/tex]Final velocity of the automobile; [tex]v = ?[/tex]
To determine the final velocity of the automobile, we use the First Equation of Motion:
[tex]v = u + at[/tex]
Where v is final velocity, u is initial velocity, a is acceleration and t is time taken.
We substitute our given values into the equation
[tex]v = 15m/s + [ 2m/s^2 * 10s ]\\\\v = 15m/s + 20m/s\\\\v = 35m/s[/tex]
Therefore, the final speed of automobile moving at the given initial speed and acceleration is 35m/s.

Four rods that obey Hooke's law are each put under tension. (a) A rod 50.0 cm50.0 cm long with cross-sectional area 1.00 mm21.00 mm2 and with a 200 N200 N force applied on each end. (b) A rod 25.0 cm25.0 cm long with cross-sectional area 1.00 mm21.00 mm2 and with a 200 N200 N force applied on each end. (c) A rod 20.0 cm20.0 cm long with cross-sectional area 2.00 mm22.00 mm2 and with a 100 N100 N force applied on each end. Order the rods according to the tensile stress on each rod, from smallest to largest.
Answer:
c < a = b
Explanation:
The tensile stress = Force applied/(Cross sectional area)
(a) The applied force = 200 N
The cross sectional area = 1.00 mm² = 1 × 10⁻⁶ m²
The tensile stress = 200 N/(1 × 10⁻⁶ m²) = 200,000,000 Pa = 200 MPa
(b) The applied force = 200 N
The cross sectional area = 1.00 mm² = 1 × 10⁻⁶ m²
The tensile stress = 200 N/(1 × 10⁻⁶ m²) = 200,000,000 Pa = 200 MPa
(c) The applied force = 100 N
The cross sectional area = 2.00 mm² = 2 × 10⁻⁶ m²
The tensile stress = 100 N/(2 × 10⁻⁶ m²) = 50,000,000 Pa = 50 MPa
Therefore, the tensile stress from smallest to largest are;
(a) 50 MPa, < (b) 200 MPa = (a) 200 MPa
Therefore, we have;
c < a = b.
