Question: A block of mass 5kg is at rest on a smooth horizontal surface.wter coming out of pipe horizontally at the rate 2 kg s, hits the block with a velocity of 6 ms.the initial acceleration of the block is?
Ans:
Given,
m = 5 kg
rate of water (dm/dt) = 2 kg/sec
We know that,

The SI unit of pressure is Pascal (represented as Pa) which is equal to one newton per square metre (N/m-2 or kg m-1s-2).
The CGS unit of pressure is barye (Ba), equal to 1 dyn·cm−2, or 0.1 Pa.

A block of mass m is suspended by a light thread from an elevator. the elevator is accelerating upward with uniform acceleration ‘a’.
we know, Newton's law doesn't valid in non-inertial frame of reference. so, we have to add Psuedo force just opposite direction of it motion to make inertial frame of reference.
so, tension in the thread = mg + ma→ [ Psuedo force]
tension = m(g + a)
now, we have to find displacement of elevator.
use formula, S = ut + 1/2 At²
here A is net acceleration acts on elevator.
here u = 0, A = a [ upward direction]
so, S = 0 + 1/2 at²
hence, displacement is 1/2at²
now, workdone = Tension × displacement
= m(g + a) × 1/2 at²
= 1/2 m(g + a)at² Joule

The energy required to remove an electron from a neutral isolated gaseous stom and convert it into a positively charged gaseous ion is called ionisation energy or first ionisation energy.
Ionisation energy required to remove the second electron from a monovalent cation is called second ionization energy.
Similarly, the energy required to remove the third electron from a divalent cation is called the third ionisation energy.
