Answer:In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. The ray can be formed by any wave: optical, acoustic, microwave, X-ray and so on. In the figure below, the line representing a ray makes an angle θ with the normal. The angle of incidence at which light is first totally internally reflected is known as the critical angle. The angle of reflection and angle of refraction are other angles related to beams.

Hi there!
We can calculate linear momentum using the following:
p = linear momentum (kgm/s)
m = mass (kg)
v = velocity (m/s)
Calculate:
Now, we can relate force, time, and momentum with the following:
I = Impulse (kgm/s)
F = Force (N)
t = time (s)
Rearrange to solve for force:
The impulse is equal to the change in momentum. Since the car comes to a halt, all of its momentum is lost, so:
Solve:
**Negative force since the positive direction is towards the wall, and the negative direction is away from the wall.
Think of this as a parabola, there is no resistance but what comes up must come down, which would represent gravity, therefore your answer would be A.
Power is the rate of doing work, P = W/t. As is implied by the equation for power, a unit of power <span>is equivalent to a unit of work divided by a unit of time. We calculate as follows:
P = W/t = Fd/t where d/t = v
P = Fv = 110(80)
power is 8800 watts</span>
The heat from inside the jacket transfers heat to her body also known as conduction.
