Answer:
The temperature on 16th August is 23.37 degree Celsius.
Explanation:
In Los Angeles, the temperature at 3:00 p.m on Aug 16th is 73.9 °F. It is required to convert it into degree Celsius.
The conversion from Fahrenheit to Celsius is as follows :
[tex]C=(F-32)\times \dfrac{5}{9}\\\\C=(73.9-32)\times \dfrac{5}{9}\\\\T=23.27^{\circ} C[/tex]
So, the temperature on 16th August is 23.37 degree Celsius.

What is the potential energy of two charges of +4.6 μC and +1.0 μC that are separated by a distance of 10.0 cm?
Answer:
U = 0.413 J
Explanation:
the potential energy between two charges q1 and q2 is given by the following formula:
[tex]U=k\frac{q_1q_2}{r}[/tex] (1)
k: Coulomb's constant = 8.98*10^9 NM^2/C^2
q1: first charge = 4.6 μC = 4.6*10^-6 C
q2: second charge = 1.0 μC*10^-6 C
r: distance between charges = 10.0 cm = 0.10 m
You replace the values of all variables in the equation (1):
[tex]U=(8.98*10^9Nm^2/C^2)\frac{(4.6*10^{-6}C)(1.0*10^{-6}C)}{0.10m}=0.413\ J[/tex]
Hence, the energy between charges is 0.413 J

Blue textbooks are blue because they absorb every color except blue and reflect the blue color so you see the blue. That is why the textbook is blue so it absorbs every color except blue.
Explanation:
Two runners ran side by side each holding one end of a horizontal pole. What would most likely happen if one of the runners began jogging in knee-deep water?
Answer:
Hope this helps :)
The runner in the water would be going slower than the other runner. The pole would be in a slanted position and one runner would be ahead of the other.
Explanation:
Water makes you slow down, therefore it would cause the runner jogging in knee deep water to move slower than the runner outside of the water. Because one runner is moving slower than the other, the pole would be in a slanted position.
The runner throughout the water would've been traveling at a moderate speed than some of the other speeds.
This same pole would've been angled, as well as one runner would've been forward of one another. Water slows someone downward immediately, which is why a runner running in lower extremity waters will go slower than that of a racer beyond the waters or pool. Although one runner was traveling slower than another and, the flagpole would've been tilted.Thus the above response is correct.

Nephrons and filtration work because the fluid going into the nephron capsule is under _________ pressure than the fluid outside the capsule.
Answer
Hydrostatic pressure
Explanation:
Filtration occurs as pressure forces fluid and solutes through a semipermeable barrier with the solute movement affected by particle size. Hydrostatic pressure is the pressure produced by a fluid against a surface. The blood inside the glomerulus creates glomerular hydrostatic pressure which forces fluid out of the glomerulus into the glomerular capsule. The fluid in the glomerular capsule creates pressure pushing fluid out of the glomerular capsule back into the glomerulus, opposing the glomerular hydrostatic pressure. This is the capsular hydrostatic pressure. These fluids exert pressures in opposing directions. Net fluid movement will be in the direction of the lower pressure.

A ray in oil (n = 1.52) reaches a boundary with water (n = 1.33) at 55.9 deg. Does it reflect internally or refract into the air?
Answer:
Ray reflects internally
Explanation:
Given:
Ray in oil (n1) = 1.52
Ray in water (n2) = 1.33
θ = 55.9°
Computation:
Step 1 . Find critical angel(θc)
Sinθc/Sin90° = Ray in water / Ray in oil
Sinθc/1 = 1.33/1.52
θc = 61°
Since, θ = 55.9° is smaller than θc = 61°
So, Ray reflects internally.
Answer: refracts it

A negative charge is moving across a rook from south to north. A magnetic field runs from East to west. In what direction is the magnetic force on the moving negative charge?
A. Toward the East
B. Toward the west
C. Toward the floor
D. Toward the ceiling
Answer:
The magnetic force on the moving negative charge is towards the ceiling.
Explanation:
The magnetic force acting on a wire is given by the relation as follows :
[tex]F=q(v\times B)[/tex]
q is charged particle
v is velocity of charged particle
B is magnetic field
In this case, a negative charge is moving across a rook from south to north. A magnetic field runs from East to west.
q = -q
v =+j
B = -i
So,
[tex]F=-q(vj\times B(-i))[/tex]
Since, [tex]j\times i=-k[/tex]
So,
[tex]F=q(v\times B)(-k)[/tex]
So, the magnetic force on the moving negative charge is towards the ceiling.
A 0.500 kg mass is oscillating on a
spring with k = 330 N/m. The total
energy of its oscillation is 3.24 J. What is the maximum speed of
the mass?
thank you in advance for your help!
Answer:
3.6m/s
Explanation:
The following data were obtained from the question:
Mass (m) = 0.5Kg
Spring constant (K) = 330N/m
Energy = 3.24J
Velocity (v) =..?
The velocity of the mass can be obtained as follow:
E = ½mv²
3.24 = ½ × 0.5 × v²
3.24 = 0.25 × v²
Divide both side by 0.25
v² = 3.24/0.25
Take the square root of both side
v = √(3.24/0.25)
v = 3.6m/s
Therefore, the speed of the mass is 3.6m/s

PLEASE HELP!!!!! An electron jumps from one energy level to another in an atom radiating 4.5*10^-19 Joules. If Planck's constant is 6.63*10^-34Js, what is the wavelength of the radiation? (C =3*10^8) 2)
Answer: λ = 4.42 × 10^-7 metres
Explanation:
The emitting radiation energy is the change in energy dE. Where
dE = 4.5×10^-19J
Planck's constant h = 6.63*10^-34Js,
Speed of light C = 3×10^8
The wavelength(λ) of the radiation can be calculated by using the formula
(λ) = hC/dE
Substitute all the parameters into the formula above
(λ) = (6.63×10^-34 × 3×10^8)/4.5×10^-19
(λ) = 1.989^-25/4.5×10^-19
(λ) = 4.42×10^-7 m
Therefore, the wavelength (λ) of the radiation is 4.42 × 10^-7 metres

3. The circuit below shows two outdoor lights, run by a battery. Four amps of
current leave the battery. Explain how the current splits to go through both light
bulbs. Be as specific as you can.
Answer:
The answer to your question is given below.
Explanation:
From the diagram given in the question, we can see that the bulbs are in parallel connection. This implies that different current will go through the bulb but the same voltage. But the resistance of each bulb is the same, therefore the same current current will go through them.
This can further be understood if we determine the current flowing through each bulb. This is illustrated below:
Voltage (V) = 30V
Resistant 1 (R1) = 15Ω
Current 1 (I1) =..?
V = I1R1
30 = I1 x 15
Divide both side by 15
I1 = 30/15
I1 = 2A.
Voltage (V) = 30V
Resistant 2 (R2) = 15Ω
Current 2 (I2) =..?
V = I2R2
30 = I2 x 15
Divide both side by 15
I2 = 30/15
I2 = 2A.
The overall current(I) in the circuit:
I = I1 + I2
I = 2 + 2 = 4A.
From the illustrations above, we can see that the same current will flow through each bulb as the will current split into two equal parts

Why do you lose balance while standing on a bus often. Need a expert to answer this. Must choose if 1st 2nd or 3rd Newton Law. And explain Please help.
Answer:
The loss of balance while standing on a bus often is due:
The third Newton law.Explanation:
The third Newton law from Latin says: "Action is always opposed an equal reaction: or the two bodies on each other are always equal, and in opposite directions," which means that when a force is exercised in a direction by a body, the other body in the interaction exercises a force in the other direction. In the case of the person on the bus, when the bus makes a force forward, your body makes a force in the other direction (back), in a similar case, when the bus stops, its force in directed to the back, in that time your body make a force forward, in each case your body can lose balance because your center of gravity is directed in the same direction in which the opposite force to that of the bus moves.

A yellow laser provides 210 kJ/mol of energy to excite electrons in a sample. What is the frequency of this light?
Answer:
Frequency, [tex]f=5.24\times 10^{14}\ Hz[/tex]
Explanation:
It is given that, a yellow laser provides 210 kJ/mol of energy to excite electrons in a sample. We need to find the frequency of this light.
Energy, E = 210 kJ/mol
i.e.
[tex]E=210\ \dfrac{kJ}{mol}\\\\E=210\times 1000\ \dfrac{J}{mol}\\\\E=\dfrac{21\times 10^4\ J/mol}{6.022\times 10^{23}\ /mol}\\\\E=3.48\times 10^{-19}\ J[/tex]
The energy used to excite electrons is given by :
[tex]E=hf\\\\f=\dfrac{E}{h}\\\\f=\dfrac{3.48\times 10^{-19}}{6.63\times 10^{-34}}\\\\f=5.24\times 10^{14}\ Hz[/tex]
