A motorcycle has a mass of 250kg. It goes around a 13.7m radius turn at 96.5km/h. Calculate the centripetal force on the motorcycle?
An object falls because of gravity at the rate of -920 cm/s2 (- sign is indicative of a downward direction) for 10.00 Seconds. If it starts from rest (vo = 0) and its position starts from do= 0.0, where is it 10.00 Seconds later.
A gasoline engine absorbs 2,600 J of heat and performs 1,000 J of mechanical work in each cycle. Find the total of heat expelled in each cycle.
One sphere is negatively charged, with net charge -2.25 mu C, and other sphere is positively charged, with net charge 4.00 mu C. The charge is uniformly distributed within the volume of each sphere.
