Photovoltaic cells are well known for their ability to convert solar energy (1) into electrical energy.
When you kick a ball the when your foot hits the ball the force from your foot is now on the ball and if the ball bumps into somoene they might fall(if you kick hard)
Answer:
Velocity = frequency * wave length
Explanation:
Wave velocity is the measure of how fast the wave is being transmitted to a particular direction.
velocity implies both speed and direction as we know.
The velocity of a wave is equal to the product of its wavelength and frequency
where
- frequency - number of oscillations per unit time (measured in Hz)
- wave length - distance between corresponding points of two consecutive waves (measured in meters)
