Answer:
Cold Front. A side view of a cold front (A, top) and how it is represented on a weather map (B, bottom).
Warm Front. ...
Stationary Front. ...
Occluded Front.
Answer:
Front 3 is an occluded front. A cold air mass moves toward warmer air. The colder, heavier air pushes the warm air upward until it’s wedged between two cold air masses. Clouds can form from the lifting of the warm air.

A 1,100kg car is going at 22 m/s. What force is needed to stop it in 20
seconds?
A 1,100 kg car is going at 22 m/s. Force is needed to stop it in 20
seconds is 1210 N.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Using equation of motion,
v = u + at
0 = 22 + a.20
a = 1.1 m/sec²
force = mass.acceleration
force = 1100.(1.1)
force = 1210 N.

The bones of the middle ear cause which structure in the inner ear to vibrate and change the sound into signals?
a) eardrum
b) cochlea
c) hammer
d) auricle
Answer:
B
Explanation:
The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus.
Answer:
the answer is the cochlea
Explanation:
the eardrum receives the sounds and the cochlea "decifers them" so you know what words people are saying or what sound is playing.
A - 28.4-μC charge is placed 16.4 cm from a charge q, the force between the two charges is 1240 N. What is the value of q?
Answer:
1.31×10⁻⁴ C or 131 μC
Explanation:
From the question,
Applying Coulomb's Law,
F = kqq'/r²..................... Equation 1
Where F = Force between the charges, q = first charge, q' = second charge, r = distance between the charges, k = coulomb's constant.
make q' the subject of the equation
q' = F×r²/(kq)
q' = Fr²/kq................ Equation 2
Given: F = 1240 N, r = 16.4 cm = 0.164 m, q = 28.4 μC = 2.84×10⁻⁵ C,
Constant: k = 8.98×10⁹ Nm/C²
Substitute these values into equation 2
q' = (1240×0.164²)/[(2.84×10⁻⁵)×(8.98×10⁹)
q' = (33.35104)/(25.5032×10⁴)
q' = 1.31×10⁻⁴ C
q' = 131 μC

The mass of an object is 84 kg. Find its weight on the Earth and the Moon.
Answer:
We would take the mass given, 80 kg, and multiply it times the acceleration of Earth's downward pull on that mass, 9.8 m/s/s. So the weight on Earth is 784 newtons. So the weight of the same 80 kg mass on the moon is 133.28 N.
hi
mass is express in Newtons.
On Earth gravity is 9.807 so wieght would be : 9.807 * 84= 823.79
On the Moon garvity is 1.62 so weight would be : 84 *1.62 = 136.08

a hot iron bar is placed 100ml 22C water. the water temperature rises to 32C. how much heat did the water gain and how much heat did the iron bar lose? Q=change T x C x M
Answer:
Water gained: 10Iron lost: -10Explanation:
Given: Hot iron bar is placed 100ml 22C water, the water temperature rises to 32C
To find: How much heat the water gain, how much heat did the iron bar lost
Formula:Q = change T x C x M
Solve:
How much heat water gained
Initial heat = 22, then rose to 32. To find how much heat the water gained, simply subtract the current heat by the initial heat.
32 - 22 = 10
The water gained 10 amounts of heat.
How much heat Iron lost
Current heat = 32, then dropped to 22. To find how much heat the Iron lost, simply subtract the initial heat by the current heat.
22 - 32 = -10
The Iron lost -10 amounts of water.
A window cleaner has a weight of 839.86 N. The window cleaner is cleaning windows on the 4th floor of a building at a height of 12 m. How much potential energy does the window cleaner have?
Answer:
E = 10078.32 J
Explanation:
Given that,
The weight of a window cleaner, F = 839.86 N
The window cleaner is cleaning windows on the 4th floor of a building at a height of 12 m.
We need to find the potential energy of the window cleaner. We know that the potential energy of an object is given by :
E = mgh
Put values,
E = 839.86 × 12
E = 10078.32 J
So, the window cleaner will have 10078.32 J of potential energy.

A negative 6 mC charge enters a region of 45 T magnetic field that is directed up. If the charge is moving toward the south with a speed of 400 m/s
Question: A negative 6 mC charge enters a region of 45 T magnetic field that is directed up. If the charge is moving toward the south with a speed of 400 m/s. determine the magnitude and direction of the force
Answer:
Magitude of F = 108 N
Direction: Perpendicular to the plane containing v and B.
Explanation:
From the question,
Since the velocity of the charge(v), is parallel to the field(B).
Therefore, We apply
F = qvB..................Equation 1
Where F = Force, B = magnetic field, v = velocity, q = Charge.
Given: q = 6 mC = 0.006 C, v = 400 m/s, B = 45 T
Substitute these values into equation 1
F = 0.006×400×45
F = 108 N.
The direction of the force is always perpendicular to the plane containing v and B.

How are proton and electron associated?The number of protons within the nucleus of the atom is identical to the atomic range. The variety of electrons in an impartial atom is identical to the number of protons. The mass range of the atom (M) is equal to the sum of the wide variety of protons and neutrons inside the nucleus.
Protons definitely charged subatomic particles that live in the nucleus. Neutrons: Neutrally charged subatomic particles that are living in the nucleus. Electrons: Negatively charged subatomic debris found inside the electron shells surrounding the nucleus.
An electron is a negatively charged factor of an atom while the proton is an undoubtedly charged frame. The electrons are present out of doors the nucleus inside the orbiting shells. But the protons alongside neutrons shape the nucleus of the atom and are gifted in the middle of the atomic nuclei.

Answer:
the vertical component of the force is 43.30 N.
Explanation:
Given;
angle of inclination of the force, θ = 60⁰
magnitude of the force, F = 50 N
The vertical component of the force is calculated as follows;
[tex]F_y = F \times sin(\theta}\\\\F_y = 50 N \times sin(60)\\\\F_y = 50 N \times \frac{\sqrt{3} }{2} \\\\F_y = 25\sqrt{3} \ N\\\\F_y = 43.30 \ N[/tex]
Therefore, the vertical component of the force is 43.30 N.

The energy transferred to the water in 100 seconds was 155 000 J. specific heat capacity of water = 4200 J/kg °C
Determine the mass of water in the kettle.
Use Figure 10.
Give your answer to 2 significant figures.
Any help would be appreciated
Answer:
0.37 kg
Explanation:
I'm not a professor myself, but this is how I worked it out:
using the graph, after 100 seconds, the temperature is 100 degrees Celsius.
If we now substitute everything into the specific heat capacity equation, making the mass "m", we would come up with:
4200 = 155000/(m x 100)
If we rearrange and solve for m, we get 0.37 kg.
I'm not sure if I have done this correctly, feel free to correct me.
Hope this helps!
By using the specific heat capacity formula, the mass of water in the kettle is 0.47 kg
Give that the energy transferred to the water in 100 seconds was 155 000 J and the specific heat capacity of water = 4200 J/kg °C
From the graph;
The initial temperature of the water at time zero is 22 degree Celsius
The final temperature of the water at time 100s is 100 degree Celsius
Change in temperature (T) = 100 - 22 = 78 degree Celsius
To determine the mass of water in the kettle, use the heat energy formula below
E = mcT
Substitute all the parameters into the equation
155000 = 4200 x 78 M
Make M the subject of the formula
M = 155000/327600
M = 0.47 kg
Therefore, the mass of water in the kettle is 0.47 kg
