Who was the last astronaut to walk on the moon? Neil Armstrong Alan Shepard Ken Mattingly Eugene Cernan

Two charged objects separated by some distance attract each other. if the charges on both objects are doubled with no change in distance between them, what happens to the magnitude of the force between the objects?

What to forces keep things In orbit

For a constant voltage, how is the resistance related to the current? Resistance is inversely proportional to current, so when the resistance doubles, the current is cut in half.

How is heat naturally transferred between objects

A pendulum consists of a 1.7-kg block hanging on a 1.6-m length string. A 0.01-kg bullet moving with a horizontal velocity of 828 m/s strikes, passes through, and emerges from the block (initially at rest) with a horizontal velocity of 340 m/s.

10. If the wavelength of the light is decreased, the width of the central maximum in the diffraction pattern will B) increase A) decrease C) remain the same

Materials with a density__water will float in water

A 0.5 kg ball is thrown horizontally towards a wall with a speed of 10 m/s. The initial velocity is chosen to be the positive x - direction for this question.

Does heat rise or fall

Two small, positively charged spheres have a combined charge of 5.23 x 10^-5 C. If each sphere is repelled from the other by an electrostatic force of 1.00 N when the spheres are 2.
