A loudspeaker is generating sound in a room. At a certain point, the sound waves coming directly from the speaker (without reflecting from the walls) create an intensity level of 75.1 dB. The waves reflected from the walls create, by themselves, an intensity level of 58.3 dB at the same point. What is the total intensity level?
A 5.0- kg block oscillates with an amplitude of 0.090 m on a light spring of constant k = 28.0 N/m. What is the maximum value of the block's velocity
A 0.030 kg lead bullet hits a steel plate, both initially at 20?C. The bullet melts and splatters on impact. What is the minimum speed the lead bullet must have in order to melt on impact
Your friend decides to produce electrical power by turning a coil of 100,000 circular loops of wire around an axis parallel to a diameter in the Earth's magnetic field, What will be the average power obtained from this device
Say you want to make a sling by swinging a mass M of 1.9 kg in a horizontal circle of radius 0.036 m, using a string of length 0.036 m. How strong will the string need to be
An east-west electric power line carries a 500-A{\rm A} current toward the east. Determine the direction of this magnetic field at Earth's surface directly under the wire
The sound intensity of a whisper is 1.0x10^-10 W/m^2 at one meter distance from the source. At what distance does the intensity level drop by an additional 1dB
A balloon rises at at constant velocity of 3m/s. A rock is released over the side. 4.5 seconds later this rock hits the ground. compute the height of the rock when it is halfway between the balloon and the ground. Assume Earth gravity (-9.81m/s), ..
Starting from rest, you pull the string with a constant force F = 8 N along a nearly frictionless surface. At the instant while the center of the disk has moved a distance x = 0.12 m, a length d = 0.27 m of string has unwound off the disk.
