Agolf ball is dropped from rest from a height of 9.5m. it hits the pavement then bounces back up rising just 5.7 m before falling back down again. a boy then catches the ball on the way down when it is 1.20 m above the pavement. ignoring air resistance, calculate the total amount of time the ball is in the air, from drop to catch.

Amagnetic field applies forces on: a)static chargesb)moving chargesc)water flow

How much work would it take to move a coulomb charge across a 4 volt potential difference?

Tsunamis are fast-moving waves often generated by underwater earthquakes. in the deep ocean their amplitude is barely noticeable, but upon reaching shore they can rise to an astonishing height of a six-story building. one tsunami generated off the aleutian islands in alaska, had a wavelength of 897km and traveled a distance of 3280km in 4.18h. (a) what was the speed (in m/s) of the wave? find the waves (b) frequency and (c) period.
