A planetary explorer vehicle on Earth weighs 557 pounds, what would it weigh on the
surface of Venus, which has 9/10 the gravity
of Earth?
A. more than on the Earth
B. less than on the Earth
C. the same as on Earth

B. less than on the Earth

Explanation:

Weight is determined by gravity. Less gravity means less weight. The vehicle would weigh 501.3 pounds on Venus.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

d.) circle motion requires a force to give it a centripetal acceleration.
