What will happen if I put my hand in a space vacuum.

You are exploring a distant planet. When your spaceship is in a circular orbit at a distance of 630 km above the planet's surface, the ship's orbital speed is 4900 m/s. By observing the planet, you determine its radius to be 4.48*106m.

What happens when an electric current passes through a wire?

A small car of mass m and a large car of mass 4m drive along a highway at constant speed. they approach a curve of radius r. both cars maintain the same acceleration a as they travel around the curve.

Two physics professors challenge each other to a 100 m race across a football field. The loser will grade the winner's lab reports for a month. Dr. Nelson runs the race is 10.40s. Dr. Bay runs the first 25.0 m with an average speed of 10.
