In Europe, gasoline efficiency is measured in km/L. If your car's gas mileage is 37.0 mi/gal , how many liters of gasoline would you need to buy to complete a 142-km trip in Europe? Use the following conversions: 1km=0.6214mi and 1gal=3.78L. Express your answer numerically in liters.

The asteroid 243 Ida has a mass of about 4.0×1016kg and an average radius of about 16 km (it’s not spherical, but you can assume it is). Calculate the speed with which you would have to throw a rock to put it into orbit around the asteroid 243 Ida, near the surface. How long would it take for your rock to return and hit you in the back of the head?

The International Space Station typically travels in a circular orbit at an altitude of 400 km above the Earth's surface. The Earth itself has a radius of about 6400 km. Assume that the space station travels in a circular orbit at constant speed (this is a perfectly reasonable assumption). A. Given that the value of g is 8.68m/s28.68m/s2at an altitude of 400 km, determine the value of the space station's speed in its circular orbit. _______ m/s B. At this...

The mass of a meteor with a radius of 1 km is about 9 x 1012 kg. The mass of a meteor also is proportional to the cube of its radius. Suppose a meteor with a radius of 8.8 km is moving at 1.8 x 104 m/s when it collides inelastically with the Earth. The Earth has a mass of 5.97 x 1024 kg and assume the Earth is stationary. The kinetic energy lost by the asteroid in this collision...

The space shuttle typically travels in a circular orbit at an altitude of 500 km above the Earth's surface. The Earth itself has a radius of about 6400 km. The shuttle can travel in a circular orbit, at constant speed, without any need for the rocket engine to be on, if it travels at just the right speed (a) Given that the value of g is 8.50 m/s2 at an altitude of 500 km, determine the value of the shuttle's...

The average radius for the planet earth is 3.96 x 103 miles. Given that the atomic weight of aluminum is 26.9815 and the atomic radius is 0.143 nm (nanometers), calculate: -the length of the line formed in meters if the atoms in 27.2 g of aluminum were placed side by side? - how many times the line in the question above, would stretch around the Earth?
