Answer: The correct option is B.

Explanation:

In the given circuit, the circuit is closed as the battery is connected to the circuit and the current is flowing.

The two bulbs connected in the circuit are in series combination as the same amount of current is flowing in the bulbs.

In the parallel combination, the amount of current flowing in the circuit across resistance is different.

Therefore, the provided circuit is closed series circuit.

A sheet of gold foil has a volume of 0.750 cm3. If the foil measures 50.0cm by 10.0cm, what is the thickness of the foil?

vlada-n [284]

To calculate the thickness of foil, we use formula of volume as

$V= l w t$

Here, l is the length of the foil, w is the width of the foil and t is the thickness of the foil.

Given, $V = 0.750 \ cm^3$ , $l = 50 cm$ and $w = 10 \ cm$ .

Substituting theses values in above equation, we get

$0.750 \ cm^3 = 50 cm \times 10 \ cm \times t \\\\ t = 0.0015 cm$

Thus, the thickness of the foil is 0.0015 cm.

What is ohm law form?

Lady_Fox [76]

Answer:

$V=RI$

Explanation:

Ohm's law states the relationship between voltage, resistance and current in an electrical circuit containing passive elements only:

$V=RI$

where

V is the voltage supplied by the battery

R is the resistance of the circuit

I is the current

From the equation, we see that the voltage, V, is directly proportional to the current in the circuit, I.

As a young boy swings a yo-yo parallel to the ground and above his head, the yo-yo has a centripetal acceleration of 250 m/s2 .

Ahat [919]

Centripetal acceleration ac is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity (tangential speed) v and has the magnitude:

$a_c = \dfrac{v^2}{R}$

Solving for v:

$v = \sqrt{a_c R} = \sqrt{(250\;m/s^2)(0.50\;m)} = 5\sqrt{5}\;m/s \approx 11.18\;m/s$
