Six dogs pull a two-person sled with a total mass of 220 kg. the coefficient of kinetic friction between the sled and the snow is 0.08. the sled accelerates from rest at 0.75 m/s2 until it reaches a speed of 12 km/h. a) what is the work done by the dogs in the accelerating phase? b) what is the maximum power output by the dogs? c) what is the pulling force from the dogs (assumed to be horizontal)?

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
