Answer:
96%
Explanation:
To find the values of the motor efficiency you use the following formula:
P_o: output power = 864J/0.5min=864J/30s=28.8W
P_i: input power = I*V = (3A)(12V) = 36W
By replacing this values you obtain:
hence, the motor efficiency is about 96%
traslation:
Pentru a găsi valorile eficienței motorului, utilizați următoarea formulă:
P_o: putere de ieșire = 864J / 0.5min = 864J / 30s = 28.8W
P_i: putere de intrare = I * V = (3A) (12V) = 36W
Înlocuind aceste valori obțineți:
prin urmare, eficiența motorului este de aproximativ 96%
Answer:
in chemistry, and in physics, a dynamic equilibrium exists once a reversible reaction occurs.
Explanation:
Substances transition between the reactants and products at equal rates, meaning there is no net change. Reactants and products are formed at such a rate that the concentration of neither changes :)
Answer:
Terminology: Energy - Is the ability to do work. Work - Is the measure of energy transferred when a force acting over a distance. Power - Is the rate at which energy is transferred, used, or transformed

Thank you
Answer:
when angle between them is zero degree
Hello.
The gaseous state is the more compressible state, because it has the volume of its container.
The liquid state is virtually incompressible, and the solid state compression is very small.
The plasma is another state that has high compression, but in this case the matter is not bound(we don't have the proton in the core of the atom)
