Can an object have increasing speed while its acceleration is decreasing?
a)no, this impossible because of the way in which acceleration is defined
b)no, because if acceleration is decreasing the object will be slowing down
c)yes, an example would be an object released from rest in the presence of air friction.

The heliocentric and the geocentric models of the solar system included these central principles

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) =_
