Yes.
Joules also refer to work as a measurement of power necessary during a time. One amp through a one-ohm resistance for one second would convert 1 joule of energy to heat.
For example: a watt requires one joule per second. If there were 50 joules used in that second, it would be 50 watts of power.
Power measured in watts can be converted to other dimensions of work, such as horsepower, Btu/hr, dBm, tons of refrigeration, etc.
Yes, because power is a measure of how quickly work is done. In this case, the power for the 200 joules of work done in 20 seconds would be 10 watts, while the power for the 50 joules of work done would be 2.5 watts. Hence, 200 joules of work done involves more power than 50 joules of work done.
Two different units that represent work are joules (J) and ergs (erg). Joules are a standard metric unit for work and energy, while ergs are a unit commonly used in physics and are equal to 10^-7 joules.
The power required to do 60 joules of work in 20 seconds is determined by the formula: Power = Work / Time. Therefore, Power = 60 joules / 20 seconds = 3 watts. So, 3 watts of power is necessary to do 60 joules of work in 20 seconds.
The heat generated by 1700 joules of work depends on the efficiency of the process. In an ideal case where all the work is converted into heat, the heat generated would also be 1700 joules. However, in real-world scenarios, the heat generated would be less due to energy losses.
No. It is not reasonable. If that ever happened, we would have to ask where the additional 40 joules came from, since energy cannot be created or destroyed. If there were something inside the box that added 40 joules to the 110 passing through, then that 40 would need to be added to the "input" work.
Work is measured in Joules.

Force times work doesn't give joules. Joules is a unit of energy or work. Perhaps you mean the relation: force x distance = work.
Work is measured in Joules.
Work is energy, measured in joules. The rate of work, or joules per second, is known as watts, or power.
Yes, because power is a measure of how quickly work is done. In this case, the power for the 200 joules of work done in 20 seconds would be 10 watts, while the power for the 50 joules of work done would be 2.5 watts. Hence, 200 joules of work done involves more power than 50 joules of work done.

Manufacturing. A machine has a work output of 14ax4 j (joules) and a work in put 7a2x5 j. What is the eficiency of the machine? efficiency in % = work output in joules work input in joules
Work is energy, measured in joules. The rate of work, or joules per second, is known as watts, or power.
The efficiency of the lever can be calculated as the ratio of the output work to the input work, multiplied by 100% to express it as a percentage. In this case, the efficiency would be 870 joules (output work) divided by 930 joules (input work), multiplied by 100% which equals 93.55%.
