Answer:
benefits
Diversifying energy supply and reducing dependence on imported fuels.
Creating economic development and jobs in manufacturing, installation, and more.
drawbacks
Large areas of landfill are required
Hydroelectric power is generated from flowing water, which turns turbines and generates electricity
Explanation:
Because ice is less dense than liquid water,
its melting point is lowered under high pressures.
A long standing theory says that this is what causes ice to be slippery:
As you step on it, the pressure of your weight causes the top layer to my into water.
Answer:
A. 231.77 J
B. 5330.71 J
C. 46 donuts
Explanation:
A. To lift the barbell once, she will have to extend it the full length of her arm. The work done will then be:
W = F * d
Where the force is the weight of the barbell.
F = m * g
Hence, the work done in lifting the barbell is:
W = m * g * d
W = 43 * 9.8 * 0.55
W = 231.77 J
B. If she does 23 repetitions, the total energy she expend will be equal to the Potential energy when the barbell is lifted multiplied by 23:
E = 23 * m * g * d
E = 23 * 231.77
E = 5330.71 J
C. 1 Joule = 4.184 calories
5330.71 Joules = 5330.71 * 4.184 = 22303.69
If 1 donut contains 490 calories, the number of donuts she will need will be:
N = 22303.69/490 = 45.5 donuts or 46 donuts
D) the ability to make things happen
Explanation:
Energy is simply defined as the ability to do work or to make things happen. Energy is important to all aspects of living and non-living things. Based on the law of conservation of energy "energy can neither be created nor destroyed but can be transformed from one form to another".
Different forms of energy exists such as heat, thermal, chemical, mechanical, sound, electrical, e.t.c
