A legend of the northland part 1

The object at rest suddenly explodes into three parts with the mass ratio 2:1:1 . The parts of equal masses move at right angles to each other with equal speeds. What is the speed of the third part after the explosion?

Divide 184 into two parts such that one-third of one part may exceed one-seventh of the other part by 8.

Divide Rs1,870 into three parts in such a way that half of the first part, one-third of the second part and one-sixth of the third part are all equal.

A vessel of volume V is divided into two parts by a partition. The pressure of the gas in one part is p_(1) and that in the other part is p_(2) . If the partition is removed find the pressure of the gas in the vessel.

A projectile is moving at 20 m s^(-1) at its highest point where it breaks into equal parts due to an internal explosion. Just after explosion, one part moves vertically up at 30 ms^(-1) with respect to the ground. Then the other part will move at :

Cell the unit of life part 1

In the adjacent figure of a typical dicot embryo, label the parts (1),(2) and (3) . State the function of each of the labelled part.

Why there is not more than 1.1 parts of ozone per million parts of air in the lower part of atmosphere?

A bomb at rest explodes into two parts of masses m_(1) and m_(2) . If the momentums of the two parts be P_(1) and P_(2) , then their kinetic energies will be in the ratio of:

One projectile moving with velocity v in space, gets burst into 2 parts of masses in the ratio 1:3 . The smaller part becomes stationary. What is the velocity of thhe other part?
