The radius of jupiter is 11 times that of earth, and the free-fall acceleration near its surface is 2.5 times that on earth. if we someday put a spacecraft in low jupiter orbit, its orbital speed will be:

Students design a model roller-coaster track. they place a rubber ball at the highest point on the track and let it go. the ball rolls along the track pulled only by the force of gravity. eventually, it comes to a stop. which change to the design will result in the ball moving the greatest distance?

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
