A radio station transmits wave of wavelength 280m If the speed of the wave is 3x108 m/s. Find the frequency of the wave emitted by the radio station. 3. A body of mass 10kg is dropped from a height of 20m. Find (i) its potential energy before it is dropped. (ii) its kinetic energy it is8m above the ground and (iii) its kinetic energy when it hits the ground. @jsuniltutorial.in 4. A tube-well pumps out 2400 kg out of water per minute if water is coming out with a velocity of 3m/s. What is the power of the pump? How much work is done if the pump runs for 10 hours? 5. Calculates the change that should be affected in the velocity of a body to maintain the same kinetic energy. If the mass of the body is increased four times. 6. The frequency of a body is 20 Hz. If the velocity of the waves produced is 340 m/s. Find the wavelength of the wave. 7. Two pistons of hydraulic press have diameters 24cm and 2cm. Calculate the force exerted by the longer piston when 40 kg wt. is placed on the smaller piston. 8. A ball is dropped from rest from a height of 12m. If the ball loses 25% of its KE on striking the ground what is the height to which it bounces? How do you account for the loss in K.E.?
