What is the tangential acceleration of a bug on the rim of a 12.0 in. diameter disk if the disk moves from rest to an angular speed of 75 rev/min in 4.0 s?

Two point charges are on the y-axis. A 3.0 µC charge is located at y = 1.35 cm, and a -2.04 µC charge is located at y = -1.50 cm. (a) Find the total electric potential at the origin (V) (b) Find the total electric potential at the point having coordinates...

Suppose that you wish to fabricate a uniform wire out of 0.900 g of copper. Assume the wire has a resistance R = 0.500 , and all of the copper is used. (a) What will be the length of the wire? (m) (b) What will be the diameter of the wire? (µm)

i need help

R=.28*165 (calc this) plug into following equation and that will give you W =I^2*R =1030^2*R b. P(loss)= IV =1030(720000) <---changed into V from kv =741400000 divide answer from part a by this number to get the percentage

yes thanks not a lot

thats not helping at all
