Answer:
Radiation is the emission or transmission of energy in the form of waves.
Explanation:
.
<span>An example of a high energy electromagnetic wave is "X-Ray"
When car runs, it's chemical energy (gasoline) converts into mechanical energy
Temperature is the measure of hotness or coldness of the body, so when heat expose to a substance, it's degree of hotness increases & it's temperature increases
Hope this helps!

Force applied on the car due to engine is given as
towards right
Also there is a force on the car towards left due to air drag
towards left
now the net force on the car will be given as

now we can say that since the two forces are here opposite in direction so here the vector sum of two forces will be the algebraic difference of the two forces.
So we can say



So here net force on the car will be 150 N towards right and hence it will accelerate due to same force.
Answer:
hmax=81ft
Explanation:
Maximum height of the object is the highest vertical position along its trajectory.
The vertical velocity is equal to 0 (Vy = 0)

we isolate th (needed to reach the maximum height hmax)

The formula describing vertical distance is:

So, given y = hmax and t = th, we can join those two equations together:


if we launch a projectile from some initial height h all you need to do is add this initial elevation
