Answer:
Explanation:
As we know that the equation of particle position is given as
Now the speed of the particle is given as
now we know that potential energy and kinetic energy is equal
so we have
so we will have
Answer:
D
Explanation:
The rubber rod having been rubbed with fur get a net negative charge thereby gaining more mass which means the mass has increased compared to before it was rubbed against the fur while the glass rod having been rubbed with the silk to give it a net positive has lost mass and therefore has less mass compared to before it was rubbed on the silk.
Answer:
Total energy of the object = mgh. As it falls, its potential energy will change into kinetic energy. If v is the velocity of the object at a given instant, the kinetic energy = 1/2mv2.
Explanation:
Explanation:
work done=force ×distance
force=Mass ×accelleration
work done=50×8×0.4
=160J
