Q. Why nichrome is used as heating element in electric heating devices?
Nichrome, an alloy of nickel as well as chromium is used as the heating element for the following reasons.
(1) It has high precise resistance
(2) It has elevated melting point
(3) It is not easily oxidized
Write down the differential equation for a simple harmonic oscillator subjected to a damping force proportional to the velocity (v) of the oscillator and the periodic force of angu

Superposition principle The general idea is that, while a number of influences are working on a system, the total influence on that system is just the sum of the individual in
Mass energy relation - The total energy of a body is the sum of its kinetic energy and rest mass energy. Particle having rest mass zero always move with the velocity of light.
A man pushes a couch a distance of 0.75 m. If 113 J of work is done. what is the magnitude of the horizontal force applied?
#quest. While music is on you will try to oppose the two ear phone pieces to attract.
Total height of the gymnast just before falling back down is=(2+.3)=2.3m Energy gained at that point = m*g*h(m=mass, g=gravitational force, h=height) =55*9.8*2.3=1239.7 J
If a great point-mass is removed by a weightless, inextensible and perfectly flexible string from a rigid support, then this arrangement is known as a simple pendulum.
