100 gm of copper is heated to increase its temperature by $21^\circ C$. If the same amount of heat is given to 50 gm of water, then the rise in its temperature is (Specific heat of Cu = $400~J~kg^{-1}K^{-1}$, Water = $4200~J~kg^{-1}K^{-1}$):

A uniform rod of mass 20 kg and length 1.6 m is pivoted at its one end and can swing freely in the vertical plane. The angular acceleration of the rod just after the rod is released from rest in the horizontal position is:

The potential energy of a particle of mass 1 kg which is in simple harmonic motion along X-axis is given by $U(x)=4(1-\cos 2x)$. The time period of oscillations is:

Which of the following statements are correct for a particle in simple harmonic motion? I. Its velocity-displacement graph is a parabola. II. Its velocity-time graph is sinusoidal. III. Its velocity-acceleration graph is an ellipse.

The figure shows the revolution of the planet (P) around the sun (S) in an elliptical orbit. Which of the following statements is true regarding time taken?

A wire can sustain a weight of 100 kg before it breaks. The wire is cut into two equal parts. Without breaking each part can hold weight up to:

Two particles of masses $m_1$ and $m_2$ ($m_1 > m_2$) are separated by a distance 'd'. When the positions of the two particles are interchanged, the shift in the centre of mass is:

A body is moving in a straight line with constant power. The distance moved by the body in time t is proportional to:

Two identical balls P and Q having velocities $0.7 m s^{-1}$ and $-0.4 m s^{-1}$ respectively are colliding in one dimension elastically. The velocities of P and Q after the collision respectively are:

A particle moves with velocity $v = at - bt^2$ where a and b are constants. The acceleration becomes zero at:

The percentage decrease in range of a projectile projected at $30^\circ$ when compared to maximum range is:

A machine gun of mass 20 kg fires bullets, each of 40 g at the rate of 120 bullets per minute with a speed of $100 m s^{-1}$. The recoil velocity of the gun is:

If force, $F=kv^{n}$ (k is constant) and power delivered is independent of velocity 'v', then n equals to:

Fertilizer prepared from the scrap fish is:

Assertion (A): The p53 gene is often called guardian angel of human genome. Reason (R): It inhibits the development of tumors.

Statement I: The change in frequency of a gene that occurs merely by chance and not by selection in small populations is called genetic drift. Statement II: The existence of deleterious genes within the population is called genetic load.

Darwin called the macro-variations as:

Expression of more than one phenotypic trait by a single gene is known as:

II. Gene responsible for haemophilia-C lies in autosomes.
III. In sickle cell anaemia in the $\beta$-chain of haemoglobin, valine is replaced by glutamic acid at 6th position.
IV. Cystic fibrosis is due to mutation in the gene located in 7th chromosome.
