Application +4 | -1

A motor is used to deliver water at a certain rate from a given pipe. To obtain 3 times water from same pipe in same time, by what factor should power of the motor be increased.

View answer and explanation

Correct option: D

27 times

Option D (27 times) is correct because the power required is proportional to the cube of the flow rate, and the flow rate is tripled.

ball is dropped on the ground from a height of

2 {~m}

. If the coefficient of restitution is 0.6 , the height to which the ball will rebound is A running man has the same kinetic energy as that of a boy of half his mass. The man speed up by

2\mathrm{\;m}{\mathrm{s}^{ - 1}}

and the boy changes his speed by

x = \mathrm{m}{\mathrm{s}^{ - 1}}

, so that the kinetic energies of the boy and the man are again equal. Then x in

\mathrm{m}{\mathrm{s}^{ - 1}}

is A force

\mathrm{\vec F} = - K\left( {y\hat i + x\hat j} \right)

(where K is a positive constant) acts on a particle moving in the x-y plane. Starting from the origin, the particle is taken along the positive x-axis to the point (a,0) and then parallel to the y-axis to the (a,a). The total work done by the force

\mathrm{\vec F}

on the particle is A body projected vertically from the earth reaches a height equal to earth’s radius before returning to the earth. The power exerted by the gravitational force is greatest The speed limit of a car over a roadways bridge in the form of a vertical arc is

9.8\;\mathrm{m}{\mathrm{s}^{ - 1}}

. The diameter of the are is Work done when a force,

\mathrm{\vec F} = \left( {\hat i + 2\hat j + 3\hat k} \right)

N acting on a particle takes it from the point

{\mathrm{\vec r}_1} = \left( {\hat i + \hat j + \hat k} \right)
