Part A A 3.7 x 1010 kg asteroid is heading directly toward the center of the earth at a steady 20 km/s. To save the planet, astronauts strap a giant rocket to the asteroid perpendicular to its direction of travel. The rocket generates 5.0 x 10° N of thrust. The rocket is fired when the asteroid is 4.9 x 106 kmaway from earth. You can ignore the rotational motion of the earth and asteroid around the sun. If the mission...

What is the angular kinetic energy of the Earth due to its orbit around the sun? In Homework 10, you found the two main angular velocities of the Earth: one due to the Earth's motion around the sun, and one due to its rotation about its own axis. Now let's figure out the energy and momentum associated with that motion. IVO ALV O a ? For the purposes of this problem, treat the Earth as a solid, uniform sphere with...

1. All the planets orbit the Sun in the same direction. This is strong evidence that: Group of answer choices None of these is correct. We do not have any idea yet why the planets are orbiting in the same direction. the solar system resulted from the collision of two medium-sized stars. after the planets formed, collisions between them eventually caused them all to move in the same direction. the planets were formed elsewhere in the galaxy and were later...

Answer all three parts
The sun transfers energy to the earth by radiation at a rate of
approximately 1.00 kW per square meter of surface. Part A If this
energy could be collected and converted to electrical energy with
26 % efficiency how large an area (in square kilometers) would be
required to collect the electrical energy used by the United
States? (1.0×1019 joules per year).
