Avolleyball is hit from an initial height of 1 foot. the ball has an initial vertical velocity of 58 feet per seconds. does the ball reach a height of 55 feet? 52 feet? explain your reasoning.

How does convection affect our atmosphere? our layers of earth? our oceans?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.
