John drives at 28 m/s for 2800 m. Then stops and rests for 300 s. Then drives at 25 m/s for 1100 m

1.80 kJ of heat is added to a slug of gold and a separate 1.80 kJ of heat is added to a slug of manganese. The heat capacity of the gold slug is 149J/°C while the heat capacity of the manganese slug is 505 J/°C.

In what direction does an applied force move an object? In the same direction as the force Independent of the force In the opposite direction of the force Perpendicular to the force

A 25eV electron has a speed of

Does an object in rest have potential energy

What is the region where the magnetic force will affect other magnets?

How to calculate wavelength in m when you know the frequency?

Ball A has a mass of 0.200 kilograms. Ball A, traveling at a velocity of 2 meters/second in the + x direction, hits a stationary ball B of the same mass. After the collision, ball B bounces off at a positive angle with respect to the + x-direction.

10. If the wavelength of the light is decreased, the width of the central maximum in the diffraction pattern will B) increase A) decrease C) remain the same

Materials with a density__water will float in water

A 0.5 kg ball is thrown horizontally towards a wall with a speed of 10 m/s. The initial velocity is chosen to be the positive x - direction for this question.
