Answer:
The Andromeda is a galaxy which is nearest to the milky way. It is also named as Messier 31 or M31 or NGC 224. It is a spiral galaxy located at a distance of approximately 2.5 million light years from earth.
another name Andromeda in Hindi is Vaikunth.
The car is the heaviest object there and mass is proportional to force, meaning the heavier it is the bigger the force should be in order to move it.
Answer:
The moment of inertia of the bar is 
Explanation:
Given that,
mass of bar = 150 g
Length l = 36 cm
We need to calculate the moment of inertia of the bar
Using formula of moment inertia
Where,
M = mass of the bar
L = length of the bar
Put the value into the formula
Hence, The moment of inertia of the bar is
An electrical generator and motor are two machines that operate oppositely.
An electrical generator uses mechanical energy, converting it to produce electrical energy. This mechanical energy is provided in most cases from a spinning/rotating action in which a wire or loop of wire spins in a magnetic field. This causes the wire to move sharply through the magnetic field, causing current to flow, and in turn, creating electricity.
An electrical motor does the opposite, but uses the same principles, converting electrical energy to produce mechanical energy. The motor will have an alternating current (AC) moving through pairs of magnets, producing a rotating magnetic field. This causes the motor's central rotor to spin, powering whatever machinery it is hooked up to.
