1. Solve for Resistance
R = 6V / 0.34 Ω

2. Solve for Current flow
I = 12 V / 50 Ω

What properties of a moving object are used in determining the object's energy of motion

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

Ball bearings are made by letting spherical drops of molten metal fall inside a talll tower-called a shot tower- and solidify as they fall. a-if a bearing needs 4.0 s to solidify enough for impact, how high must the tower be? b- what is the bearing's impact velocity?
