Expression for kinetic energy
Ek= ½ mv2
m = Mass of object
v = Velocity of the object in ms−1
Given that kinetic energy, Ek=25J
(i) If the velocity of an object is doubled, then...
(a) Kinetic energy of an object is defined as the energy possessed by a body by virtue of its motion.
It is given by, K.E = 1/2 mv2
No, the kinetic energy...
Ground state energy of hydrogen atom, E = − 13.6 eV
This is the total energy of a hydrogen atom. Kinetic energy is equal to the negative of the total energy.
Kinetic...
True
In an inelastic collision, the final kinetic energy is always less than the initial kinetic energy of the system. This is because in such collisions, there is always a loss...
K = 8.62 x10–5 eV/k
K.E. of H2 molecules = 3/2 KT
Energy released, when atom goes from ground state to no = 3
=>13.6 (1/1 – 1/9) => 3/2 KT = 13.6(1/1...
In one dimensional elastic collision of two bodies of equal masses.
The initial velocities of bodies are interchanged after collision.
Velocity of the neutron after collision is zero.
Hence, it has zero energy.
