A doubly ionized molecule (i. e., a molecule lacking two electrons) moving in a magnetic field experiences a magnetic force of 5.31 × 10 − 16 N as it moves at 369 m/s at 61.7 ∘ to the direction of the field. Find the magnitude of the magnetic field.

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.

When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?
