Mars rotates on its axis once every 24.8 hours. What is the speed of a geosynchronous satellite orbiting Mars? What is the altitude of a geosynchronous satellite orbiting Mars?

The center of a 1.40 km diameter spherical pocket of oil is 1.50 km beneath the Earth's surface. Estimate by what percentage g directly above the pocket of oil would differ from the expected value of g for a uniform Earth? Assume the density of oil is 8.0...

Estimate the acceleration due to gravity at the surface of Europa (one of the moons of Jupiter) given that its mass is and making the assumption that its density is the same as Earth's

With what tension must a rope with length 2.10m and mass 0.115kg be stretched for transverse waves of frequency 39.0hz to have a wavelength of 0.790m ?

Tuning a Cello. A cellist tunes the C-string of her instrument to a fundamental frequency of 65.4 Hz. The vibrating portion of the string is 0.625m long and has a mass of 15.0 G. Tension: 160 N What percent increase in tension is needed to increase the fr...
