A screw allows us to apply force over a greater distance with less effort. This allows us to exert a rotational force to tighten or loosen objects without the need for excessive physical strength.

How much power is required to do 100 j of work on an object in a time of 5 how much power is required if the same work is done in 1 s?

Power is the rate at which work is done. To find the power required to do 100 J of work in 5 s, divide the work by the time: 100 J / 5 s = 20 watts. If the same work is done in 1 s, the power required would be 100 watts, as power is inversely proportional to time.


What situations involves more power200 J of work in 20 s or 50 J of work done in 4 s?

Both situations have the same power output of 10 watts, as power is calculated as work done divided by time taken. In this case, 200 J of work done in 20 s and 50 J of work done in 4 s both result in a power output of 10 W.


Which of the following situations involves more power 200 j of work done in 20 s or 50 j of work done in 4 s?

The situation that involves more power is when 200 J of work is done in 20 s. Power is calculated as work done divided by time taken, so for the first situation the power is 10 W (200 J / 20 s) compared to 12.5 W for the second situation (50 J / 4 s).


What did virchlows work have in common with Pasteur's work with the s shaped tube?

Both Virchow's work on cell theory and Pasteur's work with the S-shaped tube contributed significantly to the field of biology. Virchow's work emphasized that all cells come from pre-existing cells, challenging the idea of spontaneous generation. Pasteur's use of the S-shaped tube demonstrated that microorganisms could be present in the air and caused contamination, leading to the development of aseptic techniques in microbiology.


How much power is required to do 110 j of work on an object in a time of 0.6 s?

Power is calculated as work done divided by time taken, so power = work/time. In this case, power = 110 J / 0.6 s = 183.33 watts.
