A glider airplane is coasting horizontally when a very heavy object suddenly vanishes. As a result of this heavy object disappearing and assuming there is no horizontal air resistance,

What happens to a given volume of water when heated from 0°C to 4°C?

Two equal masses m are connected by a very light string over a frictionless pulley of mass m/2. The system has been given a push to get it moving as shown, but that push is no longer acting. In which segment of the string is the tension greater?

Consider two frictionless inclined planes with the same vertical height. Plane 1 makes an angle of 35° with the horizontal, and plane 2 makes an angle of 55° with the horizontal. Mass m1 is placed at the top of plane 1, and mass m2 is placed at the top of plane 2. Both masses are released at the same time. At the bottom, which mass is going faster?

A disk starts from rest and has a constant angular acceleration. If it takes time T to make its first revolution, in time 2T (starting from rest) the disk will make

Two points are on a disk that rotates about an axis perpendicular to the plane of the disk at its center. Point B is 3 times as far from the axis as point A. If the linear speed of point B is V, then the linear speed of point A is
