Q1. A heavy piece of hanging sculpture is suspended by a 146.0 cm long, 8.03 gm wire. When the wind blows hard, the wire hums at its basic frequency of 113.0 Hz. What is the mass of sculpture (in kg) assume that the local acceleration due to gravity is 9.80 m/s2?
Q2. If the average frequency emitted by a 200,-,rm W light bulb is 5.00 times 10^{14} , {rm Hz}, and 10.0 percent of the input power is emitted as visible light, approximately how many visible-light photons are emitted per second?
