Predict/Calculate An Extraterrestrial Volcano Several volcanoes have been observed erupting on the surface of Jupiter’s closest Galilean moon, lo. Suppose that material ejected from one of these volcanoes reaches a height of 5.00 km after being projected straight upward with an initial speed of 134 m/s. Given that the radius of lo is 1820 km, (a) outline a strategy that allows you to calculate the mass of lo. (b) Use your strategy to calculate lo’s mass.

A cart on wheels (assume frictionless) with a mass of 20 kg is pulled rightward with a 50N force. What is its acceleration?
Two-point charges of 5.00 µC and -3.00 µC are placed 0.250 m apart.a) What is the electric force on each charge? Include strength and direction and a sketch.b) What would be the magnitude of the force if both charges are positive? How about the direction?
c) What will happen to the electric force on each piece of charge if they are moved twice as far apart? (Give a numerical answer as well as an explanation.)

The figure shows two snapshots of a single wave on a string. The wave is
traveling to the right in the +x direction. The solid line is a snapshot of the wave
at time t=0 s, while the dashed line is a snapshot of the wave at t=0.48s.
