Explanation

The energy equivalent of 1 atomic mass unit (a.m.u) is given by Einstein's mass-energy equivalence formula E = mc².

1 a.m.u = 931 MeV/c², so the energy equivalent is 931 MeV.

Explanation

• The female reproductive part of a flower is called the Pistil.

It consists of three parts:

1. Stigma (receives pollen grains)
2. Style (connects stigma to ovary)
3. Ovary (contains ovules/eggs)

Explanation

Explanation

Pyridine has a lone pair on nitrogen that is not involved in resonance, making it readily available for donation.

In aniline and phenol, lone pairs are delocalized into the aromatic ring, reducing basicity.

Explanation

The law of conservation of momentum states that the total momentum of a closed system (such as a system of two bodies) remains constant over time, as long as there are no external forces acting on the system.

This means that the total momentum before a collision is equal to the total momentum after the collision.

Explanation

Explanation

Rocket works on the principle of conservation of linear momentum.

conservation of linear momentum and third law of motion

The hot gases acquire momentum in the backward direction

& the rocket acquires an equal amount of momentum in the forward direction.

Explanation

Pakistan conducted a series of nuclear tests on 28 May 1998 at the Chagai test site, in Balochistan.

5 Nuclear tests were conducted by Pakistan at 15:15 hrs PST on 28 May 1998.

The tests were performed at Ras Koh Hills in the Chagai District of Balochistan Province.

Chagai-I was Pakistan's first public test of nuclear weapons.
