Apottery wheel, initially at rest, is assumed to be a uniform disk of mass 3.0 kg and radius 20.0 cm. a 25.0 n force is applied tangentially to the rim.
(a) what is the angular acceleration of this pottery wheel?
(b) if the force is applied for 30.0 sec, find the instantaneous angular velocity at 30.0 sec.
(c) what will be the angular displacement for this wheel from t= 15 s until t= 30s?

Physics make-up packetname_cle14. an observer hears a sound with a frequency of 400 hz. if the speed of sound is 340 m/s,what is the wavelength of the sound? a. 0.85 mb. 1.2 mc. 2.75 m13.6 m15. as sound travels from steel into air, its speed decreases. if the frequency of the wavedoesn't change, what happens to its wavelength? a. it increases(b) it decreasesc. it remains the samed. there is not enough information given

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.
