Akite is hovering over the ground at the end of a straight 38-m line. the tension in the line has a magnitude of 17 n. wind blowing on the kite exerts a force of 18 n, directed 60° above the horizontal. note that the line attached to the kite is not oriented at an angle of 60° above the horizontal. find the height of the kite, relative to the person holding the line.

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_

The built in flash in a compact camera is usally capable of giving correct exsposure for distance up to how many meters?
