It's a hot sunny day and you decide to go for a drive. When you open your car door, it's a lot hotter inside than outside. Why i

s that?
A).Air pollutants entering the car make the inside warmer.
B).A greenhouse effect—heat was let in through the windows and some was trapped inside.
C).Global warming—it's getting hotter everywhere you turn.
D).The hole in the ozone layer has caused higher temperatures.

Answer:The correct answer is option B.

Explanation:

Green house effect: The process in which gases present in the atmosphere absorbs the heat of the Sun. Due to this trapped heat of Sun the temperature of Earth rises.

When we open the door of car on hot sunny day , the inside of a car is more hotter. This is because heat falling on the car's window pane gets trapped inside it and results in rise in temperature inside the car.

Hence, the correct answer is option B.

A middle-A tuning fork vibrates with a frequency f of 440 hertz (cycles per second). You strike a middle-A tuning fork with a fo
jeyben [28]

Answer:

P = 5sin(880πt)

Explanation:

We write the pressure in the form P = Asin2πft where A = amplitude of pressure, f = frequency of vibration and t = time.

Now, striking the middle-A tuning fork with a force that produces a maximum pressure of 5 pascals implies A = 5 Pa.

Also, the frequency of vibration is 440 hertz. So, f = 440Hz

Thus, P = Asin2πft

P = 5sin2π(440)t

P = 5sin(880πt)

In order to do work, the force vector must be
gregori [183]

As we know that total work done by a force is given by

W = F.d

W = Fdcos\theta

so it is product of force and displacement along same direction

as we can write it as

W = (Fcos\theta)(d)

so it must be the product of force and displacement in same directions so correct answer must be

<u>B. in the same direction as the displacement vector and the motion.</u>

Select all the statements regarding electric field line drawings that are correct.
Sophie [7]

Answer:

All statement are correct.

Explanation:

1. Electric field lines are the same thing as electric field vectors, electric field are mathematically vectors quantity. These vectors point in the direction in which a positive test charge would move.

2.  Electric field line drawings allow you to determine the approximate direction of the electric field at a point in space. Yes it is correct tangent drawn at any point on these lines gives the direction of electric filed at that point.

3. The number of electric field lines that start or end at a charged particle is proportional to the magnitude of charge on the particle, is a correct statement.

4.The electric field is strongest where the electric field lines are close together, again a correct statement as relative closeness of field lines indicate a stronger strength of electric field.

Hence we can say that all the statement are correct.
