An earth-orbiting satellite has a perigee radius of 7000 km and an apogee radius of 1 km. what true anomaly (delta f) is swept out between t = 0.5 hr. and t = 1.5 hr. after perigee passage? what area is swept out by the position vector during that time interval? a satellite orbits venus with pericenter radius of 7, 000 km and apocenter radius of 70, 000 km. find: orbit eccentricity, orbit semimajor axis (km), orbit period (hr), orbit specific energy (km^2/sec^2), velocity at pericenter (km/s), and velocity at apocenter (km/sec). find in internet/book the value of the venus gravitational constant mu. consider an orbit with eccentricity e = 0.1 and semi-major axis a = 37,000 km, and a spacecraft located at the true anomaly phi =325. compute the time of (light (in hours) to another position characterized by the eccentric anomaly e_2 = 59.

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
