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.

How to derive the fourth equation of motion?
Leya [2.2K]

Answer:

To derive the fourth equation of motion, first we have to consider the equation for acceleration and then to rearrange it. or v2 = u2 + 2as and this equation of motion can be used to find the final velocity or the distance travelled if the other values are given.

Explanation:

v= u + at

s =( u + v ) t /2

s = ut + at2/2

v2 = u2 + 2as

A block of mass 1.5 hangs at the of end of a weight cord suspended from the ceiling.what is the tension in the cord, and with wh
Len [333]

The tension in the cord is 14.7 N and the force of pull of the cord is 14.7 N, assuming the block is stationary.

<h3>What is the tension in the cord?</h3>

The tension in the cord is calculated as follows;

T = ma + mg

where;

  • a is the acceleration of the block
  • g is acceleration due to gravity
  • m is mass of the block

T = m(a + g)

T = 1.5(a + 9.8)

T = 1.5a + 14.7

Thus, the tension in the cord is (1.5a + 14.7) N.

If the block is at rest, the tension is 14.7 N.

<h3>Force of the force</h3>

The force with which the cord pulls is equal to the tension in the cord

F = T = m(a + g)

F = (1.5a + 14.7) N

If the block is stationary, a = 0, the tension and force of pull of the cord = 14.7 N.

Thus, the tension in the cord is 14.7 N and the force of pull of the cord is 14.7 N, assuming the block is stationary.
