A free body diagram shown above is for a 5kg box on a rough surface being pulled to the right at a constant speed by a string that is at an angle of 30 degrees above the horizontal. The coefficient of kinetic frictopn between the box surface id .30 the tendion on the string is most nearly

Which situation will have the highest resistance? a.long wire and high temperatureb.short wire and high temperaturec.long wire and cold temperaturedshort wire and low temperature

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
