derive expression for acceleration of particle in simple harmonic motion
Answers
Answer:
Atmospheric pressure at Mumbai would be higher. Because atmospheric pressure is higher at the surface of the earth and goes on decreasing as we move up into the earth's atmosphere. Mount Everest is a very high peak. That's why the pressure at the Mount Everest would be lower and pressure at the Mumbai would be higher.

Question 2:
Fast wind can lift off a roof from a house. Does this happen because of increased pressure or reduced pressure?
ANSWER:
Fast wind can lift off a roof from a house because fast-moving wind reduces the pressure above the roof of a house and due to reduced air pressure from upside the downside air pushes it out and lift it off.

Question 3:
A closed container has air at 20°C. Some air at 50°C is inserted into the centre of the container. In which direction will this air move–upwards, downwards or not all?
ANSWER:
The air with more temperature will be lighter and hence will rise in upwards direction to the top of the container.

Explanation:
Simple Harmonic Motion or SHM is defined as a motion in which the restoring force is directly proportional to the displacement of the body from its mean position. ... The acceleration of a particle executing simple harmonic motion is given by, a(t) = -ω2 x(t). Here, ω is the angular velocity of the particle.
