Is there a link between the number of bulbs and current drawn from the power pack?

A 3.4 g particle moving at 18 m/s collides with a 0.82 g particle initially at rest. After the collision the two particles have velocities that are directed at equal angles of 51 ◦ on either side of the original line of motion of the 3.4 g particle.

Why does light change its velocity (or slows down) when it encounters a glass lens?

How many electrons would have to be removed from a coin to leave it with a charge of + 1.39x 10 - C?

What is the wavelength of light emitted when the electron in a hydrogen atom moves from the n=5 state to the n=2 state? give your answer in nm?

The mass of an electron is 9.11 * * 10 -31 -31 kg. 1) How far apart would two electrons have to be in order for the electric force exerted by each on the other to be equal to the weight of an electron?

What is the pressure 100m below the surface of the sea, if the density of sea water is 1150kg/m3

The sum of three consecutive odd integers is - 27. A. {-7, - 9, - 11} B.{-10,-9,-8} C.{-5,-9,-13} D. {-11,-13,-15}

Ian has a mass of 58.0 kilograms. What is his weight?

A push of magnitude p acts on a box of weight w as shown in the figure. the push is directed at an angle θ below the horizontal, and the box remains a rest. the box rests on a horizontal surface that has some friction with the box.

A solenoidal inductor for a printed circuit board is being redesigned. To save weight, the number of turns is reduced by one-fifth, with the geometric dimensions kept the same.
