1. For a more difficult training session, the mass to be pushed is increased to 300 kg. If the players still produce a net force of 150 N, what is the acceleration of the 300 kg mass? 2. Did the acceleration go up or down with the increased mass to be pushed? Why did that happen?

Which of the following changes will increase the capacitance of a parallel-plate capacitor? (there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates
