Supply of a product is perfectly price-inelastic. Its demand 'decreases'. This leads to fall in real national income. Other things remaining unchange.
Real national income measures GDP in real terms or only in terms of goods and services and not the prices. When the supply is perfectly inelastic, with a fall in...

Two bodies undergo one-dimensional, perfectly inelastic, head-on collision. Derive an expression for the loss in the kinetic energy.
USE 1) IF ELASTIC COLLISION THEN ENERGY CONSERVATION K.E.(INITIAL)=K.E.(FINAL) 2) IN INELASTIC USE MOMENTUM CONSERVATION

Distinguish between elastic and inelastic collision.
No. Elastic Collision Inelastic Collision i. In an elastic collision, both momentum and kinetic energy are conserved. In an inelastic collision, momentum is conserved but kinetic energy is not conserved. ii. The total kinetic energy after collision...
