Forces of gravity depend on quantities of mass, whereas electrical forces depend on quantities of net charge.
If gravitational forces dominate over electrical forces, it can only be because the amounts of net charge involved are much much much much much smaller than the amounts of mass involved.
What I'm saying is ... this doesn't mean that there aren't huge amounts of electric charge present in stars, planets, comets, and other astronomical objects. But most of the charges are BALANCED ... there are equal amounts of positive and negative charge present in the same object, and there's very little of either kind <em>left over,</em> to be attracted or repelled by other objects.
Answer:
Explanation:
ake is 1.2 x 10^12 J. Only 6.2 x 10^11 J of electrical energy is generated when the water is released. Calculate the efficiency of this energy
Answer:
3
Explanation:
From the question given above, the following data were obtained:
Length (L) = 3 m
Height (H) = 1 m
Mechanical advantage (MA) =.?
The ideal mechanical advantage for the system can be obtained as follow:
MA = L/H
MA = 3/1
MA = 3
Therefore, the ideal mechanical advantage for the system is 3
Answer:
Compound.
Explanation:
A compound is a substance formed when two or more elements are chemically joined. Water, salt, and sugar are examples of compounds. When the elements are joined, the atoms lose their individual properties and have different properties from the elements they are composed of.
