Joe has a ring weighing 13 grams made of an alloy of 16 silver and the rest gold. He decides to melt down the rings and add enough silver to reduce the gold content to 69 . How many grams of silver should he add?
Assuming a constant acceleration for the sled, what distance does it travel during the speeding-up phase? (b) What is the net work done on the sled during the time interval?
Explain the reasons why recovery of interactive transactions is more difficult to deal with than is recovery of batch transactions. Is there a simple way to deal with this difficulty?
Light is an electromagnetic wave and travels at a speed of 3.00 x 10^8 m/s. The human eye is most sensitive to yellow-green light, which has a wavelength of 5.45 x 10^-7m. How you find out the frequency of this light?
A 350 piano slides 3.6 down a 29 incline and is kept from accelerating by a man who is pushing back on it parallel to the incline (see the figure ). The effective coefficient of kinetic friction is 0.40. Calculate the force exerted by the man.
