The wavelength of the laser light is 443 nm, and the screen is 1.95 m away from the wire. what is the diameter of the wire? (hint: one of the higher order diffraction minima lines up with a well defined x-value. also, it is perfectly safe to use the small angle approximation: sin(θ) = tan(θ

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (b) how much work is required to stop it? (give the work done on the ship. include the sign of the value in your answer.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?
