For 660 ohm resistors are connected in parallel what is the total equivalent resistance

1 answer:

7 0

The overall electrical resistance that a circuit experiences as a result of all of its resistors acting in concert against its voltage source are known as the equivalent resistance of the circuit.

<h3>What is equivalent resistance?</h3>

The total resistance, or equivalent resistance, is equal to the mathematical sum of the two resistances if there are two unequal resistors or impedances in a series.

Where the whole resistance is connected in parallel or series is known as the equivalent resistance. Electrical resistance indicates the amount of energy needed to transfer the charges, or current, across the circuit.

The total or equivalent resistance, RT, is equal to half the value of one resistor if the two parallel resistances or impedances are equal and of the same value.

what is the force of gravity attraction between an object with a mass of 0.5 kg and another object has a mass of 0.33 kg and a d

elena55 [62]

Answer:

$from \: newton \: law \: of \: gravitation \\ F = \frac{GMm}{ {r}^{2} } \\ G = 6.67 \times {10}^{ - 11} \\ M = 0.5 \: kg \\ m = 0.33 \: kg \\ r = 0.002 \: m \\ substitute \\ F = \frac{(6.67 \times {10}^{ - 11}) \times (0.5) \times (0.33)) }{ {(0.002)}^{2} } \\ = 2.75 \times {10}^{ - 6} N$

Please help 2.

Answer:

The new volume of the balloon is 8.8 L

Explanation:

Charles's Law consists of the relationship between the volume and the temperature of a certain amount of ideal gas, which is kept at a constant pressure. This law establishes that the volume is directly proportional to the temperature of the gas, that is to say that if the temperature increases, the volume of the gas increases and that on the contrary if the temperature of the gas decreases, the volume decreases.

In other words, Charles's law states that when the amount of gas and pressure are kept constant, the ratio between the volume and the temperature will always have the same value:

$\frac{V}{T}=k$

Having a certain volume of gas V1 that is at a temperature T1, by varying the volume of gas to a new value V2, then the temperature will change to T2, and it will be fulfilled:

$\frac{V1}{T1}=\frac{V2}{T2}$

In this case:

V1= 8.5 L
T1= 294 K
V2= ?
T2= 305 K

Replacing:

$\frac{8.5 L}{294 K}=\frac{V2}{305 K}$

Solving:

$V2=305 K*\frac{8.5 L}{294 K}$

V2=8.8 L

<u><em>The new volume of the balloon is 8.8 L</em></u>

I NEED HELP PLEASE, THANKS :) Why does chromatic aberration occur? Explain.

Bess [88]

Answer:

Chromatic aberration is a visual effects that distorts the image. It occurs when different wavelengths of light are focused at different distances from the lens as a result of which light passing through the prism bends and the color wavelengths are separated. This is called chromatic aberration.
