Find the right answer of the certain problem
Problem- A box of mass m that was sliding along the floor, hits an incline plane and slides up the inclined plane with angle theta at a velocity v0.
Part 1- Find an expression for the maximum height, h, above the floor that the box reaches. This expression should not depend on m or theta, but only on v0 and g.
I want the right solution of the above problem.
When ultraviolet light with a wavelength of 254 nm falls upon a clean metal surface, What is the photoelectric threshold wavelength for this metal
Show that when a nucleus decays by decay, the totalenergy released is equal to (Mp -Md -2Me) where Mp and Md are the masses of the parentand daughter atoms (neutral), and Me is the mass of anelectron or positron. Why is the electron massdoubled
A 1000 kg aircraft going 25 m/s collides with a 1500 kg aircraft that is parked and they stick together after the collision and are going 10 m/s after the collision
Electric current is charge flowing per unit time. If we increase the kinetic energy of the photoelectrons (with increasing the energy of the incident photons), mustn’t the current increase, because the charge flows more rapidly? Why doesn’t it?
