D. Amplitude has no effect on velocity.
This question might have been to confuse you with the doppler effect which states that wavelengths become longer if the object causing the waves is moving away from the observer.
They were produced inside stars.
Answer:
V(t) = (q0/C) * e^(−t/RC
)
Explanation:
If there were a battery in the circuit with EMF E , the equation for V(t) would be V(t)=E−(RC)(dV(t)/dt) . This differential equation is no longer homogeneous in V(t) (homogeneous means that if you multiply any solution by a constant it is still a solution). However, it can be solved simply by the substitution Vb(t)=V(t)−E . The effect of this substitution is to eliminate the E term and yield an equation for Vb(t) that is identical to the equation you solved for V(t) . If a battery is added, the initial condition is usually that the capacitor has zero charge at time t=0 . The solution under these conditions will look like V(t)=E(1−e−t/(RC)) . This solution implies that the voltage across the capacitor is zero at time t=0 (since the capacitor was uncharged then) and rises asymptotically to E (with the result that current essentially stops flowing through the circuit).
The kinetic energy and potential energy are the two types of the mechanical energy. The generators are used to produce electricity, which is basically the electrical energy. Hence, the generators convert kinetic energy (mechanical energy) into the electrical energy which is supplied to our homes.
Hence, the correct answer is: Mechanical energy to the Electrical energy
To solve this problem we will rely on the theorems announced by Newton and Coulomb about the Gravitational Force and the Electrostatic Force respectively.
In the case of the Force of gravity we have to,
Here,
G = Gravitational Universal Constant
= Mass of Proton
= Mass of Electron
d = Distance between them.
In the case of the Electric Force we have,
k = Coulomb's constant
= Charge of proton
= Charge of electron
d = Distance between them
Therefore
We can here prove that the statement is True
