The planet Saturn has a satellite, Calypso, which travels in an orbit of radius 2.950×108 m with a period of 1.89 days. Calculate the mass of Saturn from this information.
1.0 C charge is 15 meter from a second charge, then the force between then is 1.0 Newton; determine the magnitude on the second charge
A cylinder with a piston contains 0.250 mol of ideal oxygen at a pressure of 2.25x105 Pa and a temperature of 355K. The gas first expands isobraically to three time sits original volume. It is then compressed isothermally back to its original volume,..
The 20-g centrifuge at NASA's Ames Research Center in Mountain View, Determine the rotation rate, in revolutions per second, required to give the astronaut a centripetal acceleration of 19.8g
A photon of wavelength 4.28 x 10^-2 nm strikes a free electron and is scattered at an angle of 32.0 degrees from its original direction. find the energy gained by the electron
A torque of 60 Nm producing a counterclockwise rotation is applied to the wheel about its axle. A frictional torque of 10 nm acts at the axle.If the wheel is observed to accelerate at the rate of 2rad/s2 under the influence of these torques, what i..
Two metal balls A and B of negligible radius, connected by a taut nonconducting thread of length 1.30 m, are floating at rest on Space Station Freedom between two metal bulkheads.
In an adventure movie, a 60.0-kg stunt woman falls 8.00 m and lands in a huge air bag. Her speed just before she hit the air bag was 10.6 m/s. How much work is done by gravity on the stunt woman
