<h3>Answer: D) 30</h3>

Angle of incidence always equals angle of reflection. Think of a tennis ball being hit into a wall. The ball will bounce off at the same angle that it approached with. The angles mentioned are formed through the line called the "normal", which is the line perpendicular to the surface.

A 11 547,83-N car is raised using a hydraulic lift, which
kati45 [8]

Answer:

75457.54816 N

Explanation:

F_1 = Initial force

F_2 = Weight of car = 11547.83 N

r_1 = Smaller radius = 5 cm

r_2 = Larger radius = 19.56 cm

From Pascal's law we have

\dfrac{F_1}{A_1}=\dfrac{F_2}{A_2}\\\Rightarrow F_1=F_2\dfrac{A_1}{A_2}\\\Rightarrow F_1=11547.83\dfrac{\pi r_1^2}{\pi r_2^2}\\\Rightarrow F_1=11547.83\dfrac{5^2}{19.56^2}\\\Rightarrow F_1=754.57548\ N

The force is 754.57548 N
