12. A bucket filled with water having a
mass of 15kg is raised from a well of depth
12m with the help of a rope. If the work
done to do so is 2160J, the linear density
of the rope is (g=10ms-2)
1) 0.2kg/m 2) 0.1 kg/m
3) 1 kg /m
4) 0.5 kg/m

Aneutron and a proton combine to form a nucleus. why does the mass of the nucleus differ from the sum of the masses of the individual nucleons?

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

What are similarities and differences between refraction, reflection, diffraction and absorption?
