NEET Physics MCQs

The position-time graph of a particle is a semicircle with radius $R$. The average velocity of the particle over the entire journey is:

The velocity-time graph of a particle is given by $v = v_0(1-e^{-kt})$, where $v_0$ and $k$ are constants. The displacement of the particle at time $t$ is:

The acceleration of a particle is given by $a = -ω^2x$. The graph representing the variation of velocity ($v$) with displacement ($x$) will be:

A ball is thrown vertically upwards. Which of the following graphs best represents the variation of its kinetic energy with height?

A particle starts from rest and moves with a varying acceleration as shown in the graph. If the particle's velocity at $t=4$ s is $v$, its velocity at $t=8$ s will be:

A car travels at a speed of 60 km/h. What is its speed in m/s?

The wavelength of a light wave is 500 nm. Express this wavelength in meters.

The density of a substance is 2 g/cm³. What is its density in kg/m³?

A force of 5 dyne is applied on a body. Express this force in Newtons.

The pressure of a gas is 760 mmHg. What is this pressure in Pascals? (Given 1 atm = 760 mmHg = $1.013 imes 10^5$ Pa)
