Q. If an electron starts from rest at a distance of 14.0 cm from the surface of the sphere, calculate the electron's speed when it reaches the sphere's surface.
Q. A gas has a volume of 3m3 when it is at a temperature of 23K. It's temperature now hoes up to 46K. WHat is it's new volume?
A dockworker applies a constant horizontal force of 84.0\({\rm N}\) to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 12.5\({\rm m}\) in a time 4.80\({\rm s}\)
A person does 100 joules of work of pulling back the string of the bow. What will be the original speed of a 0.5 killogram arrow when it's fired from the bow.
At time a grinding wheel has an angular velocity of 22. It has a constant angular acceleration of 28.0 until a circuit breaker trips at time = 1.60 . From then on, the wheel turns by an angle of 438 as it coasts to a stop at constant angular decel..
What is the lift (in newtons) by reason of Bernoulli's principle on a wing of area 77 m^2 if the air passes over the top and bottom surfaces at speeds of 270 m/s and 140 m/s, correspondingly.
A 60 kg woman stands on a very light, rigid board that rests on the bathroom scale at each end. She is 1.5m away from one side and 0.5 m from the other.
A 40 percent efficient electric power plant produces 900MW of electric power and discharges waste heat into 30 C ocean water. Suppose the waste heat could be used to heat homes during the winter instead of being discharged into the ocean. A typical A..
