A spherical 0.34 kg orange, 2.0 cm in radius, is dropped from the top of a building of height 33 m. After striking the pavement, the shape of the orange is a 0.60 cm thick pancake. Neglect air resistance and assume that the collision is completely inelastic. a)Estimate how much time the orange took to completely "squish" to a stop? b) What average force did the pavement exert on the orange during the collision?
When 3880 J of heat are added to a 0.159-m-long silver bar, its length increases by 4.31 x 10-3 m. What is the mass of the bar
Two identical point charges are fixed distance from one another. If one of their charges was doubled an the other was halved, how would the electric force be affected.
A body of rest mass m0, travelling initially at a speed 0.6c. makes a completely inelastic collision with an identical body initially at rest, (a) What is the speed of the resulting single body? (b) What is its rest mass?
A capacitor is charged to a potential of 12.0V and is then connected to a voltmeter having an internal resistance of 3.10M(omega) . After a time of 4.10s the voltmeter reads 3.0V . What is the capacitance? What is the time constant of the circuit?
Let’s do some electrochemistry. A process for electroplating an object with gold is as follows. The object to be electroplated is immersed in a bath of gold chloride (AuCl4-) and connected to the negative terminal of a battery.
