Two identical piano wires, when tuned to a fundamental frequency of 400 Hz, produce no beats. One wire is then slightly tightened, and the beat frequency heard is 2 Hz. What is the new fundamental frequency of the tightened wire?
A pump is used to deliver water at a certain rate from a given pipe. To obtain twice the volume of water from the same pipe in the same time, by what factor must the power of the motor pump be increased?
Power supplied to a particle of mass 2 kg varies with time as $P=3t^{2}/2$ watt, where t is in seconds. If velocity at $t=0$ is zero, the velocity at $t=2$ s is:}
The potential energy of a particle is given by $U(x)=20+(x-2)^{2}$ where U is in joules and x in meters. The minimum potential energy and the position where it occurs are:}
A body of mass 1 kg starts moving from rest under the action of a force which varies with displacement as $F=2x+5$ (in newtons). The work done by this force to displace the body from $x=0$ to $x=2$ m is:
