A 6.0 μC positive charge is located at the origin and a 4.0 uC positive charge is located at x = 0.0 m y = 1.0 m Find the point between them where the electric field strength is zero.
x= 0 m y = 0.67 m
x = 0 m y = 0.55 m
x= 0 m y = 0.60 m
x = 0 m = 1.5 m

Frank just graduated from eighth grade. assuming exactly four years from now he will graduate from high school how many seconds does he have until his high school graduation

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s. when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
