Which conservation law helps you to explain this.

While firing the bullet,the gun must be held tight to the shoulder. This is a consequence of ___________.

While firing a bullet,the gun must be held tight to the shoulder. "In the firing process the speed of the gun is very low compared to the speed of the bullet." Substantiate the above statement using mathematical expressions.

While firing the bullet,the gun must be held tight to the shoulder. Show that recoil velocity is opposite to the muzzle velocity of the bullet.

While firing the bullet,the gun must be held tight to the shoulder. A gun of mass 5kg fire a bullet of mass 5g vertically upwards to a height of 100m .Calculate the recoil velocity of gun.

Why it is advisable to hold a gun tight to one's shoulder when it is being fired?

Assume that two gases X and Y at the same temperature and pressure have the same volume. b) Which law helped you to find the answer ?

Partial pressure of a vessel containing Cl_2 CO_2 and CO is the sum of the partial pressure of Cl_2 , O_2 and CO . b) Which law helped you to answer this?

During a seminar session in the class , the presenter argued that equal amounts of both H_2 and N_2 on heating at constant pressure will expand in the same rate. Another student objected this argument by saying that they will expand differently since their molecular masses are different . b) Which law helped you to reach the answer ?
