Answer:
7.35m/s
Explanation:
Kinetic energy = 1/2 MV^2
From the question
Kinetic energy = 6.8x10^3J
Mass = 225kg
V =?
Using the above formula
We have
6.8x10^3 = 1/2 x 225 x v^2
6.8x10^3 = 112.5 x v^2
Divide both sides by 112.5
We have
6.8x10^3 / 112.5 = v^2
v ^2 = 54.04
V = squared root of 54.04
v = 7.35m/s
It is not possible for Leon to be involved in a motor crash, in which the car is demolished without sustaining an injury except Leon is playing a video game.
<h3>
What is a motor crash?</h3>
A motor crash is the event in which a motor vehicle is involved in a collision amongst another motor vehicle, pedestrian, animal, or stationary object.
<h3>Impact of motor crash</h3>
A motor crash can cause the following;
- total damage of the car
- breaking of bones of the driver
- damage of properties colliding with the car
Thus, it is not possible for Leon to be involved in a motor crash, in which the car is demolished without sustaining an injury except Leon is playing a video game. In the video game he will not be involved physically with the motor crash.

Answer:
A. As air pressure in an area decreases, the density of the gas particles in that area decreases.
Explanation:
At constant temperature, pressure and density of a gas are directly related. So if pressure decreases, density decreases.
