A student uses a projectile launcher with a spring constant of 180 N/m to launch a marble with a normal force of 0.9 N vertically into the air. If the spring is initially compressed 0.03 m, what is the maximum height the marble will reach?

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
