Question

to make a saturated solution,46g of sodium chloride dissolved in 200 g of water at 293 k.find it's concentration at this temperature​

Answer 1

Explanation:

Momentum

Newton’s first law was for scenarios where net force = 0. The second law is for scenarios with net force not equal to 0. Momentum plays a crucial role in Second law.

Momentum is the product of mass of a body & its velocity

It is a Vector quantity

It is denoted by p = mv

For example, A ball of 1 kg moving with 10m/sec has a momentum 10kg m/sec.

Momentum of a system remains conserved. Therefore,

Greater force is required to set heavier bodies in motion

Greater force is required to stop bodies moving with higher velocities
