A highly charged piece of metal (with uniform potential throughout) tends to spark at places where the radius of curvature is small, or at places where there are sharp points. The breakdown electric field strength for air is about 3 106 V/m.
(a) It is possible to calculate the maximum possible potential (relative to infinity) in air of a metal sphere of 15 cm radius. First, what is the maximum charge you can put on this sphere?
CFor that amount of charge, what is the potential of the sphere relative to infinity?
volts
(b) Next, calculate the maximum possible potential relative to infinity in air of a metal sphere of only 0.2 mm radius. What is the maximum charge you can put on this sphere?
The orbit of earth's moon has a period of 27.3 days and a radius (semi-major axis) of 2.56 x 10-3 A.U. (= 3.84 x 105 km). What is the mass of Earth? What are the units? Show the work.

Huygens' principle (first described by the Dutch scientist Christiaan Huygens in 1678) uses geometry to determine the shape of a wavefront at a time.
A 246 kg wooden raft floats on a lake. as a 85 kg man stands on the raft, it sinks 5.0 cm deeper into the water. When he steps off, the raft vibrates for a while.
If the car is now at rest and the pendulum undergoes S.H.M. would its time be shorter of longer than that calculated in (b) explain your answer.
What must your average speed over the next 10 miles be to have your average speed for the total 20 miles be 13m/h? c)Given this average speed for the first 10 miles, can you possibly attain an average speed of 14for the total 20-mile ride?
A sphere of radius R is uniformly charged to a total charge of Q. It is made to spin about an axis that passes through its center with an angular speed ω. Find the magnitude of the resulting magnetic field at the center of the sphere.
What is the y component (in Newtons) of F
To water the yard you use a hose with a radius of 3.50 cm. Water flows from the hose with a speed of 1.10 m/s. If you in part block the end of the hose so the effective radius is now 0.55-cm, with what speed does water spray from the hose.
