A certain lightbulb has a tungsten filament with a resistance of 19.1 ? when at 20.0°C and 139 ? when hot. Assume the resistivity of tungsten varies linearly with temperature even over the large temperature range involved here. Find the temperature of the hot filament.
A cardinal (Richmondena cardinalis) of mass 4.00×10-2 and a baseball of mass 0.143 have the equal kinetic energy. What is the ratio of the cardinal's magnitude of momentum to the magnitude of the baseball's momentum?
A 2.65 block is pushed 1.69m up a vertical wall with a constant speed by a constant force of magnitude F applied at angle 55.4 degrees with the horizontal. g= 9.8 m/s2. If the coefficient of kinetic friction between the block & wall is 0.54, Calcu..
A 75 kg parachutist descends through a vertical height of 310 m with constant speed. Find the increase in entropy produced by the parachutist, assuming the air temperature is 21°C.
A sled is pulled with a horizontal force of 20 N along a level trail, and the acceleration is found to be 0.35 m/s2. An extra mass m = 4.2 kg is placed on the sled. If the same force is just barely able to keep the sled moving, what is the coeffic..
Clifford is in a real hurry, however, and skips the speedramp. Starting from rest with an acceleration of 0.39 m/s2, he covers the same distance as the ramp does, but in one-fourth the time. Illustrate what is the speed at which the belt of the ra..
Consider an infant who weighs 100 newtons. During each year she grows so that each dimension of her body increases by 5%. How much would she weigh then.
Three resistors, 28, 48, and 80 ?, are connected in series, and a 0.53-A current passes through them. What is the potential difference across the three resistors
A resistor is connected across the terminals of a 9 V battery, which delivers 1.27E+5 J of energy to the resistor in 8.00 hours
A uniform diving board, 12m long and 20kg mass is placed on a platform. How far can a 60kg person walk down the board from the edge of the platform without board tipping over.
A town is installing a new 10” main to carry drinking water. The only section remaining to be installed is a segment through the middle of town. Calculate the length of pipe required for the pipe system.
The acceleration of a certain simple harmonic oscillator is given by a = - (15.8 m/s2) cos (2.51t). What is the amplitude of simple harmonic motion.
