Two resistors with values of 6.0 ohms and 12 ohms are connected in parallel. This combination is connected in series with a 2.0
ivanzaharov [21]

Answer:

4A

Explanation:

According to ohm's law;

E = IRt where;

E is the source voltage = 24volts

I is the total current flowing in the circuit = ?

Rt is the total effective resistance in the circuit.

To find Rt, we will resolve the resistors in parallel first.

Since 6ohms and 12ohms resistors are in parallel, their effective resistance will give;

1/R = 1/6+1/12

1/R= 2+1/12

1/R = 3/12

3R = 12

R = 4ohms.

This resistor will now be in series with the 2.0ohms resistor to finally have;

Rt = 4+2

Rt = 6ohms

From the ohms law formula;

I = E/Rt

I = 24/6

I = 4Amperes

The total current in the circuit is 4A

This same currents will flow in the 2ohms resistor since same current flows in a series connected resistors.

A seesaw pivots as shown in below. What is the net torque about the pivot point?
rodikova [14]

Answer:

2.3 Nm clockwise

Explanation:

Take counterclockwise to be positive and clockwise to be negative.

∑τ = (3 N) (2.5 m) − (7 N) (1.4 m)

∑τ = 7.5 Nm − 9.8 Nm

∑τ = -2.3 Nm

The net torque is 2.3 Nm clockwise.

Choose the appropriate words to complete the thought. A solar powered car converts _______________ energy into _________________
Natalija [7]

The best and most correct answer among the choices provided by your question is the second choice or letter C. A solar-powered car converts light energy to mechanical energy.

Solar cars use photovoltaic cells to convert sunlight into energy. Photovoltaic cells are the components in solar panels that convert the sun's energy to electricity<span>. They're made up of semiconductors, usually silicon, that absorb the light.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

The human body is a system of systems that rely on each other to sustain a life. Explain how.
Misha Larkins [42]
The human body is connected in every way. All the organs are connected and help each other be alive. For example, the veins are connected to the heart, which help it by pumping blood and oxygen. If they weren’t there, the heart wouldn’t be able to sustain a life.
I really hope this gave you and ideas and helped you in some way:)
