A 12.4??C particle with a mass of 2.70×10?5kg moves perpendicular to a 1.01T magnetic field in a circular path of radius 22.8m .
Part A How fast is the particle moving?
Part B How long will it take the particle to complete one orbit?
A ball with a mass of 0.75 kg is thrown vertically into the air with an initial velocity of 10 m/s. establish the velocity of the ball when it hits the ground if it was initially released 2.0 m above the ground.
The fastest pitched baseball was clocked at 46 m/s. If the pitcher exerted his force (assumed to be horizontal and constant) over a distance of 1m, and a baseball has a mass of 145 g.
A 1600 kg car starts from rest at A, coasts 180m through a dip and comes to stop at B after coasting a distance d on level ground. If the rolling resistance is a constant force of 280N, conclude the distance d.
Two identical 10 g iron springs, except that one has been wound using work W, are dropped into equal volumes of 15M HC1 in two identical constant volume calorimeters, that are adiabatically insulated. The HC1 will dissolve iron springs. What differen..
