12. Which of the following is not a characteristic of transverse waves? Ia. Its energy travels in a direction which is the same as the direction of the
particles of the medium.
b. It transports energy.
c. Its energy travels in a direction which is at right angles to the direction of the
particles of the medium.
d. It is created by a vibrating source.

A. Its energy travels in a direction which is the same as the direction of the particles of the medium.

Explanation:

Because the other ones are characteristics of a transverse wave.

c. newton's third law of motion

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
