Describe briefly one problem caused by the expansion of metals

A 400 kg object is sitting at rest at the top of a hill that is 30.0m high and 80.0m long measured along the hill. If there is no friction, how fast will the object be going at the bottom of the hill?

What does P represent in the equation P=m*v?

Friction removes energy from objects in motion. Which statement best describes how this works? a) friction transforms KE into thermal energy b) friction transfers thermal energy to KE c) friction transforms TE into PE d) friction transforms PE into

Hi. Indicate which of the following physics symbols denote units and which denote variables or quantities. a. C b. c (cursive) c. C (cursive) d. t (cursive) e. T f. T (cursive)

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.
