Answer:

Power, P = 2.14 kW

Explanation:

In the given figure, the resistors R₁ , R₂ and R₃ are in parallel. So, their equivalent resistance will be:

\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}+\dfrac{1}{R_3}

\dfrac{1}{R_{eq}}=\dfrac{1}{20}+\dfrac{1}{8}+\dfrac{1}{500}  

R_{eq}=5.64\ \Omega

So, the equivalent resistance of the circuit is 5.64 ohms.

It is also given that the potential difference is 110 V. The current flowing through the circuit can be calculated from the Ohm's law :

I=\dfrac{V}{R}

I=\dfrac{110\ V}{5.64\ \Omega}

I = 19.5 A

Power drawn by the circuit is the product of the voltage and the current flowing i.e.

P=V\times I

P=110\times 19.5

P = 2145 Watts

or

P = 2.14 kW

Hence, this is the required solution.

The answer is 2.14 kW.

You get this by dividing the outside number (110) by all the resistors and then adding the values together.

How do fission nuclear reactions differ from fusion nuclear reactions?
Serhud [2]
The path of the raction occurs on the basis of mass of the nuclei involved in reaction.
In case of nuclear fusion, two or more nuclei having less mass fuse(combine, join) together to form a new nuclei(heavier mass but it is relatively stable). During fusion, matter is not conserved because some of the matter is converted into energy(light). This reaction evolves a huge amount of energy and there comes Einstein's famous Energy-mass equivalence formula E=mc^2! :D. The nuclear reaction occuring in stars(including our sun ) is "fusion".

Fission occurs with heavier nuclei such as that of Uranium-235. Which splits into smaller subatomic particles like gamma, neutrons and enormous amount of energy.
Both, Fission and Fusion releases enormous amount of energy and modern nuclear weapons works on the principle of nuclear fission.

A 0.55-μF capacitor is connected to a 3.5-V battery. How much charge is on each plate of the capacitor?
yan [13]

Answer:

1.925 μC

Explanation:

Charge: This can be defined as the product of the capacitance of a capacitor and the voltage. The S.I unit of charge is Coulombs (C)

The formula for the charge stored in a capacitor is given as,

Q = CV ................... Equation 1

Where Q = charge, C = Capacitor, V = Voltage.

Note: 1 μF  = 10⁻⁶  F

Given: C = 0.55 μF = 0.55×10⁻⁶ F, V = 3.5 V.

Substitute into equation 1

Q = 0.55×10⁻⁶×3.5

Q = 1.925×10⁻⁶ C.

Q = 1.925 μC

Hence the charge on the plate = 1.925 μC
