Ageosynchronous earth satellite is one that has an orbital period of precisely 1 day. such orbits are useful for communication and weather observation because the satellite remains above the same point on earth (provided it orbits in the equatorial plane in the same direction as earth’s rotation). calculate the radius of such an orbit based on the data for the moon in

What is the order of the moon, earth, and sun in a lunar eclipse and a solar eclipse?

Acoal-fired plant generates 600 mw of electric power. the plant uses 4.8 x 10^6 kg of coal each day, and the heat of combustion of coal is 3.3x 10^7 j/kg. the steam that drives the turbines is at a temperature of 300° c, and the exhaust water is at 37° c. (a) what is the overall efficiency of the plant for generating electric power? (b) how much thermal energy is exhausted each day? (c) what is the change in entropy of the universe for this heat engine? (d) using the same heat reservoirs, what is the maximum possible (carnot) efficiency for a heat engine?

Juliette sets the initial velocity to +10 m/s, the acceleration to zero, and clicks “start.” how can shakina describe the subsequent motion of the car juliette controls?
