Calculate the work and power when a 54 N force is applied at an angle of 35.7
degrees downward with the horizontal to move a box a distance of 6.8 meters
in 6.7 seconds.

Acharge q experiences no net force at a particular point in space. which of the following situations described below must always be true? -there are no other charges nearby. -if there are other charges nearby, they must all have the same sign as q. -if there are other charges nearby, they must all have the opposite sign of q. -if there are other charges nearby, the total positive charge must equal the total negative charge. -none of the above
