Unit for measuring Energy?
Energy is measured in Joules most often.
Which of the situations involves more power200 Joules of work done in 20 seconds or 50 Joules of work done in 4 seconds?
Use the definition of power as energy / time (or the equivalent work / time). Do the calculation for both cases, then compare.
How many kilocaclories of heat does the operation of a 1190 watt hair dryer produces each second?
Watts means joules per second. The device uses 1190 joules of energy every second; most of that will be converted to heat. It is best to use SI units most of the time; in this case, joules rather than calories for energy. However, if you want to convert that, 1 calorie = 4.184 joules; thus, you can divide the number of joules by 4.184 to convert it to calories.
What is joules in science?

Joules
What contains the most joules of energy a banana or a sausage?
1 calorie is equal to 4.186 joules. sausage is 50 calories or 209.3 joules of energy. banana is 105 calories or 439.53 joules of energy. Therefore a peeled banana contains much more joules of energy than tasty looking sausages. ;)
How many joules are in 56 kilo joules?
56 kilo joules = 56,000 joules
How do you convert from killi joules to joules?
