Answer:
velocity of the object
Explanation:
For an object moving at a constant acceleration, we would expect to see a position graph with a curved shape and a velocity graph with a straight shape.
E = 0.5mv^2 = 0.5*44*10^2 = 2200J
Answer:
a motor is used to covert electrical energy to mechanical energy
Most mutualisms involve partnerships between ectothermic organisms. Therefore, they are particularly sensitive to changes in temperature, and most will be strongly affected by climate change. A mutualism will retain stability and function only under a particular set of environmental conditions.
Answer:
Its density decreases, and its volume increases
Explanation:
Density is defined as Mass/Volume. What happens when water transforms into ice is that its density decreases because the volume the molecules now occupy increases.
The denominator of the rational expression 
is now larger (while the numerator stays the same), so the quotient gives a smaller number.
