Joaquin mows the lawn at his grandmothers home during the summer months Joaquin measured the distance across his grandmothers lawn as 11.5 meters If Joaquin mows one length across the lawn from east to west in 7.10 seconds then what is the velocity of the lawnmower

Aproton is projected toward a fixed nucleus of charge +ze with velocity vo. initially the two particles are very far apart. when the proton is a distance r from the nucleus its velocity has decreased to 1/2vo. how far from the nucleus will the proton be when its velocity has dropped to 1/4vo?

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface
