Answer:
The angular displacement of the blade is 576,871.2 radians
Explanation:
Given;
angular speed of the Helicopters rotor blades, ω = 510 rpm (revolution per minute)
time of motion, t = 3 hours
The angular speed of the Helicopters rotor blades in radian per second is given as;

The angular displacement in radian is given as;
θ = ωt
where;
t is time in seconds
θ = (53.414)(3 x 60 x 60)\\
θ = 576,871.2 radians
Therefore, the angular displacement of the blade is 576,871.2 radians
Becuase Gravity. The Earthp pulls you down, you do not pull the earth.
If the temperature is increased the particles gain more kinetic energy or vibrate faster. This means that they move faster and take more space.
Ruff's image is 50m behind the mirror surface and the image is also 3m tall.
This is because it is a plane mirror.
