The potential difference between the terminals of an electric heater is 60 V when it draws a current of 4 A from the source. What current will the heater draw if the potential difference is increased to 127.5 V ?
Due to an acceleration of 1 , the velocity of a body increases from 5 m/s to 10 m/s in a certain period. Find the displacement (in m) of the body in that period.
A body is initially moving with a velocity of 10 m/s. It undergoes an acceleration of 2 m/s2 for 5 seconds. Find the displacement (in m) of this body in these 5 seconds.
