Answer: 2.13 × 10^-4 A
Explanation:
Given that the RLC circuit has a resistance R = 200 Ω and an inductance L = 15 mH.
Its oscillation frequency F = 7000 Hz
The initial current I = 25 mA = 25/1000 or 25 × 10^-3 A
Since there is no charge on the capacitor, the current after complete 5 circle will be achieved by using the formula in the attached file.
Please find the attached file for the remaining explanation for the solution.
A force of 660 n stretches a certain spring a distance of 0.300 m. what is the potential energy of the spring when a 70.0 kg mass hangs vertically from it?
Answer:
correct answer is iron
Explanation:
solution
as Iron is only formed in the cores of the star that is more massive than the sun because it takes very much energy as gravitational force push inward on the star
and the sun can form the helium and carbon and the oxygen and also other elements
but not the iron or any iron group element
so correct answer is iron
Answer:P:Increase Q:Decrease
Explanation: The price of the product will increase as the imposed per-unit excise tax on the sale of the good. This is true for both Perfectly-elastic and relatively elastic products.
The quantity demanded of the product will decrease as the price of the product increases, this his is true for both Perfectly-elastic and relatively elastic products. It will follow the law of Demand and Supply.
Answer:
It is an instrument which increases the amount of force available to a single hypothetical person.
Examples;
Levers, pulleys are force magnifiers.
