The two major ways to transfer charge between two objects are

Which of the following is true when an object of mass m moving on a horizontal frictionless surface hits and sticks to an object of mass M > m, which is initially at rest on the surface? The collision is elastic. A.

During this chemical reaction energy is released. In the chemistry lab, this would be indicated by an increase in temperature or, if the reaction took place in a test tube, the test tube would feel warmer to the touch.

What must be true about two objects for conduction to take place?

A small glider is coasting horizontally when suddenly a very heavy piece of cargo falls out of the bottom of the plane. a. You can neglect air resistance. b. Just after the cargo has fallen out the plane speeds up but the cargo does not change speed.

A set of data is collected from a simple circuit with a 20 resistor and is represented in the table

A skydiver of mass m jumps from a hot air balloon and falls a distance d before reaching a terminal velocity of magnitude v. Assume that the magnitude of the acceleration due to gravity is g. a.

8. What happens to force when mass is increased?

Give an example of ionic and covalent bond, and explain and make an example for each.
