Which of the following could be reasonable explanations for how a piece of invisible tape gets charged? select all that apply.
(1) protons are pulled out of nuclei in one tape and transferred to another tape.
(2) charged molecular fragments are broken off one tape and transferred to another.
(3) electrons are pulled out of molecules in one tape and transferred to another tape.
(4) neutrons are pulled out of nuclei in one tape and transferred to another tape.

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

A2-kg bowling ball is 2.5 meters off the ground on a post when it falls. just before it reaches the ground, it is traveling 7 m/s. assuming that there is no air resistance, which statement is true?
