1. Mass
2. Speed
3. Kinetic energy
Equals variation in position over variation in time, here’s the formula hope it helps :)
<span>1) The resistance force relate to the effort force for the fixed pulley alone be being equal to the effort force. resistance force = effort force. 2) The mechanical advantage compare with the slope of the line for each pulley by being independent of slope. </span>
D) Move farther apart from one another. Sublimation is when a solid changes to a gaseous state. The particles that were tightly compact into a solid are released and spread away from eachother into the air as a gas.
Answer:
See explanations below
Explanation:
Power = Workdone/Time
Power of washer = 450watts
Time used to clean the clothes = 1hour = 3600secs
Energy used to clean a load of clothes in 1 hour of
washing = 450/3600
Energy used to clean a load of clothes in 1 hour of
washing = 0.125Joules
For drying;
Energy = 3000/1.5*3600
Energy = 3000/5400
Energy = 0.556Joules
Hence the energy in washing id 0.556Joules
