Answer:

Velocity (m/s) over time (s) graph

We could write out our average acceleration as:

a = Δv/ Δta=Δv/Δta, equals, Δ, v, slash, Δ, t

a = (15 m/s - 0 m/s) / 0.2 seconds

a = 15 m/s / 0.2 seconds

a = 75 m/s / second

Explanation:

What this formula is telling us is that if we know the acceleration of an object, and the ... we can plug in our acceleration of 12.5 m/s2 for a, and 4 seconds for t.

List the laws of thermodynamic and describe their relevance in the chemical reactions2. Define the standard reduction potential.

Alenkinab [10]

<h2>Energy remains constant </h2>

Explanation:

Thermodynamic Laws -

The primary law, otherwise called the Law of Conservation of Energy, expresses that energy remains constant in the overall reaction, it is not created or destroyed.

The second law of thermodynamics expresses that the entropy increases. after the completion of the reaction of any isolated system

The third law of thermodynamics expresses that as the temperature reaches towards an absolute zero point the entropy of a system becomes constant.

Standard Electronic potential -

The standard reduction potential may be defined as the tendency of a chemical species or the reactants to get into its reduced form after the overall reaction.

It is estimated at volts.

The more is the positive potential the more is the reduction of the chemical species

Aerobic grow is much more efficient at making ATP because of the presence of oxygen the cycles in the respiration are carried out at an efficient rate which forces the cell to undergo a much large amount of ATP production.
