When you compress or stretch a spring, as soon as the stress is relieved, the spring attains its normal shape instantly. Its Elastic potential energy helps it do so. Generally, these elastic substances follow the Hooke’s law.

According to this Law, the force needed to change the shape of spring is proportional to the displacement of the spring. The displacement referred here is how far the spring is compressed or stretched from its normal shape. Mathematically, Hook’s Law can be summarised as F= – k x. Here ‘k’ is the spring constant and ‘x’ is the displacement.

There are plenty of sweet-smelling herbs found on this island along with low trees and shrubs. This dense vegetation is termed as 'Maquis'. Similar vegetaion in California is known as 'Chaparral'.

M=P(1+i)^n

I=M-P

Bookkeeper is the only English word that has three consecutive double letters.

All the given reactions are Decomposition reactions.

Decomposition reaction is a reaction in which only one reactant is splitted into two or more products.

Hooke's law states that within the elastic limit, stress developed is directly proportional to the strain produced in a body.Hooke’s law is valid only in the linear part of stress-strain curve. Hence, statement 1 is correct.
