If one doubles the emfs in a circuit and doubles the resistances in the circuit at the same time, what happens to the currents t

bija089 [108]

Answer:

Same

Explanation:

Let R be the resistance of the cell and E be the emf.

Let i be the current in the circuit.

i = E / R ..... (1)

Now emf and resistance be doubled.

so, i' = 2E/2R = E/R

So, i' = i (From equation (1)

Current remains same.

What describes Newton’s law of universal gravitation

VikaD [51]

Newton's law of universal gravitation gives the gravitational force between two objects:

F = GMm/r²

F = gravitational force, G = gravitational constant, M & m are the masses of the two objects, r = distance between the objects

A car that travels from point A to point B in four hours, and then from point B back to point A in six hours. The road between p

Hitman42 [59]

Note : Be careful with speed and velocity, even the formula is same that $v = \frac{x}{t}$

1. If we would like to find the velocity, we must calculate the distance from initial to final, $x_{f} - x_{i} = (delta)x$ ,

2. If we would like to find the speed, we must calculate the total distance that travelled ( $x_{total}$ .

So, in this question, because it return back to its initial point so (delta)x = 0, so average velocity is 0 m/s.
