Acceleration can be defined as the rate of change in the velocity of an object. Option C is correct.
<h3>What is
Acceleration?</h3>
- It is defined as the rate of change in velocity.
- It can also be defined as the rate of change in position in a particular direction.
Where,
- acceleration
- change in velocity
- time
Therefore, acceleration can be defined as the rate of change in the velocity of an object.

Answer:
2,500 watts
Explanation:
I got this answer right on a test. I hope it works for you to.
A. a large amount of energy released into its surrounding
During the respiration, glucose molecules are converted to other molecules in a series of steps. They finally end up as as carbon-dioxide and water.
The overall reaction is
<span>C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 2805 kJ
</span>
The reaction is exothermic reaction because <span>C=O and O-H bonds in the products are so much more stable than the bonds in the reactants.
</span>
Bond energy is the average needed to break a bond.
Some bond energies are:
C-C = 347 kJ/mol
C-H = 413kJ/mol;
C-O = 358 kJ/mol;
O-H = 467 kJ/mol;
O=O = 495 kJ/mol;
<span>C=O = 799 kJ/mol</span>
