Q1. Under the influence of its drive force, a snowmobile is moving at a constant velocity along a horizontal patch of snow. When the drive force is shut off, the snowmobile coasts to a halt. The snowmobile and its rider have a mass of 135 kg. Under the influence of a drive force of 203 N, it is moving at a constant velocity whose magnitude is 5.60m/s. The drive force is then shut off. Find (a) distance in which the snowmobile coasts to a halt and (b) time required to do so.
Q2. Comment at length on the statement. "The space around a wire with a current in it is empty." That is, does magnetic field occupy space?
What was the average acceleration throughout the trip
A monochromatic beam of light is absorbed by a collection of ground-state hydrogen atoms in such a way that three different wave-lengths are observed while the hydrogen relaxes back to the ground state. What is the wavelength of the incident beam.
A loudspeaker of mass 22.0 {rm kg} is suspended a distance of h = 1.60 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.90 {rm m}.
What is EMF in the secondary circuit
A spring with spring constant 12.5 hangs from the ceiling. A 400 ball is attached to the spring and allowed to come to rest. It is then pulled down 6.80 and released. What is the time constant if the ball's amplitude has decreased to 3.90 after 57.0 ..
