A chemistry teacher owns 50 bowling balls. 25 of the bowling balls have a weight of 16 pounds, 10 of them have a weight of 15 pounds, and the last 15 have a weight of 14 pounds. What is the average weight of the 50 bowling balls? (type all of your work and label the correct unit) *

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

answerto predict;

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
