Answer:Developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete- Niels Bohr
Discovery of energy quanta made him the originator of quantum theory -Max Plank
Formulated the wave equation; stationary and time-dependent Schrödinger equation- Erwin Schrödinger
Best known to the general public for his "mass–energy equivalence formula" ; E = mc^2-B Albert Einstein
Postulated the wave nature of electrons and suggested that all matter has wave properties- Louis de Broglie
Explanation:
All the names mentioned above contributed towards the development of the wave mechanical model of the atom. Their names were matched with their contributions as required by the question.
Answer:
Well, temperature is simply an average measure of the kinetic energy for particles of matter. Another way of putting it would be that temperature simply describes the average vibration of particles. Because the motion of all particles is random, they don’t all move at the same speed and in the same direction.
It is 72 km/h

Simple harmonic motion is defined as a periodic motion of a point along a straight line, such that its acceleration is always towards a fixed point in that line and is proportional to its distance from that point.
Why is it called simple harmonic motion?
The motion of a particle moving along a straight line with an acceleration whose direction is always towards a fixed point on the line and whose magnitude is proportional to the distance from the fixed point is called simple harmonic motion.
Why is SHM important?
Whilst simple harmonic motion is a simplification, it is still a very good approximation. Simple harmonic motion is important in research to model oscillations for example in wind turbines and vibrations in car suspensions.
What are two basic characteristics of SHM?
Solution : The two basic characteristics of a simple harmonic motion : (i) Acceleration is directly proportional to displacement.
(ii) The direction of acceleration is always towards the mean position, that is opposite to displacement.
