A tungsten wire has a radius of 0.086 mm and is heated from 20.0 to 1422 oC. The temperature coefficient of resistivity is ? = 4.5 x 10-3(Co)-1. When 130 V is applied across the ends of the hot wire, a current of 1.2 A is produced. How long is the wire? Neglect any effects due to thermal expansion of the wire.
Sketch a free body diagram for the hot air balloon. When the burner is turned on what force is required to cause an upward acceleration of 5m/s squared?
A diffraction grating with 395 lines/mm is 1.00 m in front of a screen. What is the wavelength of light whose first-order maxima will be 16.9 cm from the central maximum on the screen.
Nobel laureate Richard Feynman (1918-1988) once said that if two persons stood at arm's length from each other and each person had 1% more electrons than protons, the force of repulsion between them would be enough to lift a "weight" equal to that..
You hang the rod vertically and attach a 74 kg mass to the bottom, and you observe that the bar becomes 1.74 cm longer. From these measurements, it is possible to conclude the stiffness of one interatomic bond in titanium.
Illustrate what are the nominal and effective interest rates? Also determine the effective interest rate that a typical credit card issuer charges today.
What is the velocity of q_{2} when the balls are 0.450 m apart. what is the speed that the bar falls.
A bucket of water with a mass of 2kg is attached to a rope that is wound around a cylinder. The cylinder has a mass of 3 kg and is mounted horizontally on frictionless hearings. The bucket is released from rest.
The other end is attaced to a 3 kg disk moving in uniform circular motion on the table, which stretches the spring by 1 cm. Note: Friction is negligibe. Illustrate what is the work done on the disk by the spring during one full circle?
A 30-06 caliber hunting rifle fires a bullet of mass 0.0122 kg with a velocity of 247 m/s to the right. The rifle has a mass of 3.2 kg. What is the recoil speed of the rifle as bullet leaves the rifle.
pipe open at one end only has a fundamental frequency of 237 Hz. A second pipe, initially identical to the first pipe, is shortened by cutting off a portion of the open end. Currently, when both pipes vibrate at their fundamental frequencies, a beat ..
