Q. A 210, 50-cm-diameter turntable rotates on frictionless bearings at 67. A 25 block sits at the center of the turntable. A compressed spring shoots the block thoroughly outward next to a frictionless groove in the surface of turntable.
What is the turntable's angular speed while the block reaches the outer edge?
Two 12-cm-diameter charged rings face each other, 17.0 apart. Both rings are charged to + 40.0. What is the electric field strength at the midpoint between two rings.
A 2.0 kg ball swings in a vertical circle on the end of an 80cm long string. Calculate the speed, magnitude and direction of acceleration
As F is enhancement d, the block would either begin to slide, or begin to tip over. What must be the coefficient of static friction ms so that the block begins to slide rather than tip.
What is the magnitude of the acceleration of a modified Atwood machine if the mass of the cart is 3 kg and the hanging mass is 4 kg? (Use g = 9.8 m/s2. Express your answer to one decimal point.)
A loudspeaker of mass 25.0 is suspended the distance of = 2.40 below ceiling by two cables that make equal angles with the ceiling. Each cable has a length of = 2.50. What is the tension in each of cables.
The potential at the center of a uniformly charged ring is 44kV, and 15.0 cm along the ring axis potential is 30kV. Find the ring's radius and its total charge.
Three charged particles are placed at corners of an equilateral triangle of side 1.20m. The charges are + 7.0 mc,-8.0 mc and -6.0 mc compute the magnitude and direction of the net force on each due to the other two.
Six artificial satellites complete one circular orbit around a space station in the same amount of time. Each satellite has mass and radius of orbit. The satellites fire rockets that provide force needed to keep a circular orbit around the space stat..
A friend is working on a biology experiment and needs to make an electric field of magnitude 460 {rm N/C} at a distance of 10 {rm cm} from the central portion of the large nonconducting square plate 5.2 {rm m} on each side.
Nitrogen and oxygen in their liquid states have densities only 0.80 and 0.90 that of water. Atmospheric pressure is due primarily to weight of nitrogen and oxygen gas in the air. If atmosphere liquefied would its depth be greater or less than 10.30 m..
