The independent variable would be the amount of sunlight because that is what you are testing and the dependent variable would be the length of time the mice slept because it is what you are measuring. The constants would be everything else water, food, cage size, exercise wheel, and temperature because they stay the same.
It is limited by the depth divers and equipment can go.
1.) A compound is a substance that originates from two or more separate elements. It shares some similarities with a mixture.
2.) A compound has quite different properties from which it was formed. It also cannot be separated easily. Compounds are formed by chemical reactions.
3.) A pure substance has a constant composition and has consistent properties. It can be a compound or an element, but its composition is constant.
Hope this helps. :)
ENERGY TRANSFORMATION is when energy is changed from one type to another
Answer:
P.E = 493920 j
Explanation:
Given data:
Mass = 1200 kg
height = 42 m
Potential energy = ?
Solution:
Formula:
<em>P.E = mgh</em>
Now we will put the values in formula.
g = 9.8 m/s²
P.E = 1200 Kg × 9.8 m/s²× 42 m
P.E = 493920 Kg.m²/s²
Kg.m²/s² = j
P.E = 493920 j
