A satellite is in a circular orbit very close to the surface of a spherical planet. The period of the orbit is 1.64 hours.
What is density of the planet? Suppose that the planet has a uniform density.
A particle oscillates with S.H.M. The maximum displacement from its mean position is 0.5 meter and frequency of motion is 10 Hz. at time t=0, particle is located at 0.15 meter and has the velocity of 24.0 m/s towards the negative x-axis.
Two idenical wavelengths λ = 4.00 meters are emitted from separate sounces. At a certain obsevation point, the path-lengh difference between two waves is 5.00 meters. At a fixed point of time (ie, at some snapshot of time), what is the phase differen..
Two solid blocks of identical size are submerged in water. One block is aluminum and the other is lead. Upon find which is the buoyant force greater
A ball of mass 5.0 kg is lifted off the floor a distance of 1.7 m. What is the velocity of ball just before it hits the floor
An air-track glider attached to a spring oscillates between the 15 {rm cm} marks and the 57 {rm cm} mark on the track. The glider completes 10 oscillations in 32 {rm s}.
A heavy crate is attached to the wall by a light rope. Another rope hangs off the opposite edge of the box. If you slowly increase the force on the free rope by pulling on it in a horizontal direction, which rope will break? Ignore friction and th..

One particle has a mass of 2.00 10-3 kg and a charge of +7 µC. A second particle has a mass of 5.00 10-3 kg and the same charge. Find the initial separation between the particles
The electric potential at a position located a distance of 22.2 mm from a positive point charge of 8.40×10-9C, Calculate the value of the second charge
In a particular beta-minus decay of a free neutron (that is, one not part of an atomic nucleus), the emitted electron has exactly the same kinetic energy as the emitted electron antineutrino. What is the value, in MeV, of that kinetic energy? Assume ..
A car (mass = 1170 kg) is traveling at 42 m/s when it collides head-on with a sport utility vehicle (mass = 2330 kg) traveling in the opposite direction
A deep-space probe moves away from Earth by a speed of 0.78c. An antenna on the probe requires 4.0 s, in probe time, to rotate during 1.0rev. How much time is required for 1.0 rev according to an observer on Earth?
