Volume of the peat moss = 
= 
Convert the above volume into 
Thus, volume in is:
Volume of peat moss = 
= 
Now,
Total volume by using area and depth of the peat moss = 
= 
= 
Convert above values in 
to get the value of volume in :
Thus, volume in is:
Total volume = 
= 
= 
Now, number of bags is calculated by the ratio of total volume of the peat moss to the volume of the peat moss.
Substitute the values of volume in above formula:
= 
≅ 
bags
Thus, number of bags of peat moss are needed to cover an area measure 
by 
to a depth of 
are bags.
Electrical to chemical energy
Explanation:
If the batteries in a flashlight are rechargeable, the energy conversion that would take place to recharge the battery is from electrical to chemical energy.
- A battery is an electrochemical cell in which chemical reactions produces electrical currents.
- This is a typical energy conversion from chemical to electrical energy.
- When such batteries are to be recharged, the revere process is followed.
- Electrical energy are used to drive chemical reactions.
- This in turn makes the battery recharged and on its own, it can further chemical reactions to produce electrical energy.
- During charging, the potential of the battery increases.

<span>A total mechanical energy of an object is calculated as the sum of kinetic energy and potential energy</span>
The answer to this question would be True.
Answer: Thomson's showed that atoms contain smaller particles, so it was important to change the theory of daltons. Rutherford found that most of of an atom is hollow and in the middle of an atom is concentrated energy. This contributed to the revision of the plum pudding model.
