The rate at which work is done is equivalent to which of the following?Select one:a.increase in potential energyb.potential energyc.thermal energyd.power

When time taken to complete a given amount of work increases, then A power increases  B power decreases  C energy consumption increases      D energy consumption decreases

If the amount of work done (W) is the same as the amount of energy transferred in by heat (Q), the net change ininternal energy is 1

If the kinetic energy of a system increases while the system's thermal energy and potential energy are unaltered, which of the following is true? The system is doing work on the environment and the total mechanical energy of the system is higher. The environment is doing work on the system and the total mechanical energy of the system is lower. The system is doing work on the environment and the total mechanical energy of the system is lower. The environment is doing work on the system and the total mechanical energy of the system is higher.

Which produces the greater change in kinetic energy (assume that all of the work goes into kinetic energy):Group of answer choicesexerting a 10 N force for a distance of 5 mexerting a force of 20 N over a distance of 2 mexerting a 30 N force for a distance of 1.5 mexerting a force of 40 N over a distance of 1 m

Which is the ratio of output work to input work?Multiple choice question.energyforceefficiencywork
