Asled is pulled at a constant velocity across a horizontal snow surface. if a force of 8.0 x 10 n is being applied to the sled rope at an angle of 53 degrees to the ground, what is the magnitude of the force of friction of the snow acting on the sled?

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
