A lightbulb is connected to a battery by two two copper wires of equal lengths but different thicknesses. A thick wire connects

one side of the lightbulb to the positive terminal of the battery and a thin wire connects the other side of the bulb to the negative terminal.
a. Which wire carries a greater current? Or is the current the same in both? Explain.

b. If the two wires are switched, will the bulb get brighter, dimmer, or stay the same? Explain.

5 1

Answer:

Explanation:

a ) Current remains the same throughout the whole of a closed circuit if all the resistances are in series. So current will remain the same in both these conductors as they are in series.

b ) If the two wires are switched or exchanged mutually , there will not be any change in the current are they will still remain in series and total resistance remains the same . so current will remain the same . Hence the current through the bulb will remain unchanged . The brightness too will remain the same.

car company wants to build a wind- powered car that converts 100 percent of the mechanical energy in the wind to the mechanical
navik [9.2K]

EVEN IF they can build such a machine, it's not too useful.

-- If the wind starts and stops, your car would do the same thing.

-- If the wind isn't blowing at all, your car is going nowhere. (and fast)

-- You could never move along the road faster than the wind is moving along the road.

-- You could never move in the direction towards where the wind is coming from.  This has been proven before, with the technological marvel known as the "sailboat".

Call your broker immediately.  Tell him you do NOT want to buy any stock in CarCompany.

How does the electric force between two charged particles change if particle's charge is reduced by a factor of 3?
MAVERICK [17]

The force between two charges is proportional to the product of the charges.

If only one of the charges is reduced by a factor of 3, then the force is reduced by a factor of 3.

If both charges are reduced by a factor of 3, then the force is reduced by a factor of 9.

Determine the voltage of source v2 in order for a 50a current to be delivered to the 0.5 ohm load resistor.
USPshnik [31]

<u>Answer</u>

25 Volts

<u>Explanation</u>

Ohm's law states that the current flowing though a fixed resistor is directly proportional to the voltage drop across it.

V ∝ I

V = RI Where R is the resistance.

V = 0.5 × 50

  = 25 V

A playground carousel is rotating counterclockwise about its center on frictionless bearings. A person standing still on the gro
Shtirlitz [24]

Answer:

1.94601 rad/s

Explanation:

I_1 = Moment of inertia of carousel = 124 kgm²

\omega_1 = Angular speed of carousel = 3.5 rad/s

\omega_2 = Angular speed of person

r = Radius of carousel = 1.53 m

m = Mass of person = 42.3 kg

Moment of inertia of person

I_2=mr^2\\\Rightarrow I_2=42.3\times 1.53^2\\\Rightarrow I_2=99.02007\ kgm^2

As the angular momentum is conserved in the system

I_1\omega_1=(I_1+I_2)\omega_2\\\Rightarrow \omega=\frac{I_1\omega_1}{(I_1+I_2)}\\\Rightarrow \omega_2=\frac{124\times 3.5}{(124+99.02007)}\\\Rightarrow \omega_2=1.94601\ rad/s

The angular speed of the carousel after the person climbs aboard is 1.94601 rad/s
