Answer:
0.00479 volts
Explanation:
From Faraday's law of electromagnetic induction, the induced emf equals the change in magnitude flux (magnetic field strength multiplied by the area = BA) divided by the time change
Therefore we have the equation
EMF = BA÷t
Since area A = 2πr
EMF = Bπr²÷t
B = 5.5×10^(-5)
Velocity = 100km/h = 27.7778m/s
r = 1m, t = r÷V = 0.036
EMF = Bπr²÷t = (5.5×10^(-5) x π x (1)²)÷0.036 = 0.00479 Volts
Answer:
I think it's carbohydrates
Explanation:
The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.
Answer:
Entropy of the universe is constantly increasing.
Explanation:
Entropy is the loss of available energy when it is in transit. The entropy of a system increases consuming the energy, this energy is now unavailable for doing the work or making the corresponding changes in the property of a system.
Entropy is the measure of randomness of a system. It is a toll that the nature takes for energy in transit.
The second law of thermodynamics concludes that all the energy cannot be transformed from one form to another and the flow of energy has a specific direction.
If a reversible process occurs, there is no net change in entropy. In an irreversible process, entropy always increases, so the change in entropy is positive. The total entropy of the universe is continuously increasing.
Answer:
F = K Q1 Q2 / R^2 force between 2 charged partices
F2 / F1 = (R1 / R2)^2 = (1 / 2.69)^2 = .139
F2 = .139 F1
