A coil with an inductance of 16.8 H and a resistance of 5.5 ? is suddenly connected to a resistanceless battery with an ? = 194.0 V. What is the rate at which thermal energy is appearing
In addition, snow exerts a retarding force on the sled that points opposite to the direction of motion, and has a magnitude of 57 N. Find out the acceleration of the sled and child.
An electron has an initial velocity of 3.50 106 m/s in the x direction. It enters a uniform electric field = (400 N/C) , which is in the y direction. (a) Find the acceleration of the electron.
Suppose you walk 3.97 m down a 30° incline while holding a 1.05 kg block. The 3.97 m distance is measured as a displacement along the incline; not as a vertical change in height. How much work do you do on the block as you walk down the incline.
If the heat engine used to harvest the energy from humans was operating at the theoretical maximum efficiency what temperature would the cold reservoir have to be make this energy source viable? (Assume the hot reservoir is that of the average ski..
A loudspeaker of mass 18.00 {rm kg} is suspended a distance of h = 1.20 {rm m} below the ceiling by two cables that make equal angles with the ceiling.
A block of mass 4.0 kg is put on top of a block of mass M = 5.5 kg. To cause the top block to slip on the bottom one, while the bottom one is held fixed, a horizontal force of at least 16 N must be applied to the top block. The assembly of blocks is ..
A jetliner is moving at a speed of 216 m/s. The vertical component of the plane's velocity is 79.70 m/s. establishes the magnitude of the horizontal component of the plane's velocity.
Although both stars probably formed from the same clump of gas, more massive one must have had its birth slowed so that it became a key -sequence star millions of years later than its less massive companion.
Calculate the mass of a solid gold rectangular bar with dimensions 3.50 cm x 14.0 cm x 27.0 cm. Density of gold is 1.93E4 kg/m^3
A 180, 48.0 cm-diameter turntables rotate on frictionless bearings at 70.0. A 15.0 block sits at the center of turntable. A compressed spring shoots the block fundamentally outward along the frictionless groove in the surface of the turntable.
