<span>when the gravitational forces and air resistance equalize on an object that is falling toward the earth and the object stops accelerating its called TERMINAL VELOCITY</span>
Answer:
25 degrees
Explanation:
The angle of incidence equals the angle of reflection
Nope. It's called 'centripetal' acceleration. The force that created it MAY be gravitational, but it doesn't have to be. For things on the surface of the Earth moving in circles, it's never gravity.
During the operation of fan we know that it is working on the electricity
So here when we connect the fan with electricity it uses the electrical energy and convert that energy into mechanical energy of fan
Fan uses this electrical energy to rotate the blades of fan and then it gives the high speed air to us
So here correct answer must be
B.
motion energy
<span>The time it takes for one wavelength to pass a fixed point is known as PERIOD.
In fact, the period is defined as the time it takes a wave to make one complete oscillation: since the wavelength is the distance between two consecutive points of the wave with same shape, it means that the time it takes for one wavelength to pass a fixed point in space is exactly the period.</span>
