Answer:
Both the parts will weigh the same
Explanation:
Energy is lost when machines don't work right. it is false because the law of conservation of energy states that energy can not be created or destroyed (lost)
The scientific law of one organism feeding off to other where energy is transferred from one form to another is known as the law of conservation of energy.
Explanation-
Energy from the the highest energy source that is sun is absorbed by plants to convert it into food (i.e a form of energy). plants are the only ones that can convert sunlight into another form of energy directly.
The animals and organisms that feed off of the plants take some part of this energy for their life cycles and then the animals that feed off of these animals again take some part of this energy and carry on with their life cycle, this is how energy from sun (highest source) is transferred to different organisms by Just changing form.
Answer:
About 2 units.
Explanation:
We assume that there is no heat dissipating instrument in the room
Total cooling load of the room is defined from the given below equation
=++
where
= 10*100 W =1 KW
= 40*360 KJ/h= 4 KW
=15000KJ/h= 4.17 KW
= 1+4+4.17=9.17 KW
the number of air conditioner unit is ==1.83
which is approximately 2 units
