If the K.E. of a particle is doubled, then its momentum will

The energy which an ${e^ - }$ acquires when accelerated through a potential difference of $1 \,volt$ is called

Two masses of $1\,kg$ and $16\,kg$ are moving with equal K.E. The ratio of magnitude of the linear momentum is

The adjoining diagram shows the velocity versus time plot for a particle. The work done by the force on the particle is positive from

A particle is moving in a horizontal circle with constant speed. It has constant

$A$ ball is projected vertically upwards. Air resistance  variation in $g$ may be neglected. The ball rises to its maximum height $H$ in a time $T$, the height being $h$ after a time $t$

$[1]$ The graph of kinetic energy $E_k$ of the ball against height $h$ is shown in figure $1$

$[2]$ The graph of height $h$ against time $t$ is shown in figure $2$

$[3]$ The graph of gravitational energy $E_g$ of the ball against height $h$ is shown in figure $3$

Which of $A, B, C, D, E$ shows the correct answers?
