Explanation:

Power is the product of current and voltage:

P = IV

And from Ohm's law, voltage is the product of current and resistance:

V = IR

So substituting this expression for V into the power equation:

P = I (IR)

P = I² R

Answer:

P = IV

Ohms law gives voltage as the product of current and resistance i.e.

V =IR

Replacing this in the previous equation gives

P= I(IR) = I^2R

Explanation:

applying ohms law V=IR

Which elements are not likely to be formed in the sun sometime during its life cycle?

Sladkaya [172]

Answer:

correct answer is iron

Explanation:

solution

as Iron is only formed in the cores of the star that is more massive than the sun because it takes very much energy as gravitational force push inward on the star

and the sun can form the helium and carbon and the oxygen and also other elements

but not the iron or any iron group element

so correct answer is iron

A solid metal sphere with radius 0.430 m carries a net charge of 0.270 nC . Part A Find the magnitude of the electric field at a

rodikova [14]

Answer:

8.46 N/C

Explanation:

Using Gauss law

$E=\frac {kQ}{r^{2}}$

Gauss's Law states that the electric flux through a surface is proportional to the net charge in the surface, and that the electric field E of a point charge Q at a distance r from the charge

Here, K is Coulomb's constant whose value is $9\times 10^{9} Nm^{2}/C^{2}$

r = 0.43 + 0.106 = 0.536 m

$E=\frac {9\times 10^{9}\times 0.270\times 10^{-9}}{0.536^{2}}=8.4581755402094007\approx 8.46 N/C$

If the x-position of a particle is measured with an uncertainty of 1.00×10-10 m, then what is the uncertainty of the momentum in

yawa3891 [41]

Answer:

The uncertainty in momentum is 5.25x 10^25Jsm

Explanation:

We know that

h bar = h/2π

1.05x 10^34=h/2pπ

h=1.05x 10^ 34(2π)=6.597x 10^-34Js

dp=(6.597x10^-34/4pπ)/(1x10^-10)

=5.25x10^-25 Jsm
