If a Cu 2 + ion that is initially at rest accelerates through a potential difference of 12 V without friction, how much kinetic energy will it gain?

In order to prevent muscle contraction from misaligning bones during healing (which can cause a permanent limp), injured or broken legs must be supported horizontally and at the same time kept under tension (traction) directed along the leg.

In order to increase the amount of work completed, it is necessary to decrease the force applied to an object. decrease the time to do the work. increase the time to do the work. increase the force applied to the object.

A golf ball (m = 46.0 g) is struck with a force that makes an angle of 44.4° with the horizontal. the ball lands 193 m away on a flat fairway. if the golf club and ball are in contact for 6.

In 2016 there were 2025 reported collisions between trains and cars that's resulted in 265 fatalities. Explain the change in kinetic energy as it relates to conservation of momentum

What does that mean about the densities of the phases of water

The amount of force needed to keep a 0.1kg basketball moving at a constant speed of 6 m/s on frictionless ice is ___ N

What three forms of kinetic energy can a polyatomic molecule have?

A parachutist bails out and freely falls 50 m. Then the parachute opens, and thereafter she deceler - ates at 2.0 m/s2. She reaches the ground with a speed of 3.0 m/s.

Why the weight of a body decreases with increases in distance from the earth's surface

On a fishing trip Justin rides in a book 12 km south. The fish aren't biting so they go for kilometers west. They then follow a school of fish 1 km north. What distance did they cover? What was their displacement?
