A 8.00?F parallel-plate capacitor with circular plates is connected to a 11.0V battery.
What is the charge on each plate?
How much charge would be on the plates if their separation were doubled while the capacitor remained connected to the battery?
How much charge would be on the plates if the capacitor were connected to the 11.0V battery after the radius of each plate was doubled without changing their separation?
A car traveling at a constant speed of 22.5 m/s passes a trooper hidden behind a billboard. One second after the speeding car passes the billboard, the trooper sets off in chase with a constant acceleration of 3.90 m/s2.
The skis have a thrust of 220 . Sam's speed at the bottom is 45.0. Illustrate what is the coefficient of kinetic friction of his skis on snow?
A loudspeaker of mass 18.00 kg is suspended a distance of h= 1.60.below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of t= 3.90 m. What is the tension in each of the cables? Use 9.80 for the magnitude ..
What is the electric potential energy of the system? (Take as zero the potential energy of the three charges when they are infinitely far apart.)" Use = 8.85 10 12 for the permittivity of free space.
When its 75kW engine is generating full power, a small single engine airplane with a mass of 700 kg gains altitude at a rate of 2.5 m/s. what fraction of the engine power is being used to make the air plane climb.
Find out separation between the two sources
Two charged objects experience a mutual repulsive force of N. If the charge of one of the objects is reduced by a factor of and the distance separating the objects is increased by a factor of , what is the new force?
Two blocks (A and B) are in contact on a horizontal frictionless surface. A 40N constant horizontal force is applied to A. The mass of A is 5.0kg and the mass of B is 20k
Block B rests on a smooth inclined plane of 21 degrees and block A hangs vertically. Compute the acceleration of the system if the mass of block A is 1.08 kg and that of block B is 5.9 kg.
A 2000 kg car traveling at a speed of 23m/s skids to the halt on wet concrete where = 0.60. How long are the skid marks.
After the Sun exhausts its nuclear fuel, its ultimate fate might be to collapse to a white dwarf state. In this state, it would have about the same mass as it has now, but its radius would be equal to the radius of the Earth.
A baseball outfielder throws a 0.150 kg baseball at a speed of 35.0 m/s and an initial angle of 26.0°. Illustrate what is the kinetic energy of the baseball at the highest point of its trajectory?
