Explanation:

The chemical properties of an element are determined by the configuration of its electrons in orbit around its nucleus. ... See a Periodic Table of the Elements. The number of protons in the nucleus of an atom is its Atomic Number.

Answer:

F' = 800 N

Explanation:

The electrical force between charges is 400 N.

The electrical force between two charges is given by :

$F=k\dfrac{q_1q_2}{r^2}$

If q₁' = 2q₁, new force becomes,

$F'=k\dfrac{q_1'q_2'}{r^2}\\\\F'=k\dfrac{2q_1\times q_2}{r^2}\\\\F'=2\times F\\\\F'=2\times 400\\\\F'=800\ N$

So, the new force becomes 800 N.

A magnet in the form of a cylindrical rod has a length of 5.51 cm and a diameter of 0.865 cm. It has a uniform magnetization of

andriy [413]

Answer:

Magnetic dipole moment will be $15.51\times 10^{-3}J/T$

Explanation:

We have given length of the cylinder , that is h = 5.51 cm = 0.051 m

And diameter of the cylinder d = 0.865 cm

So radius $r=\frac{d}{2}=\frac{0.865}{2}=0.4325cm=0.4325\times 10^{-2}m$

So volume of cylinder $V=\pi r^2h=3.14\times (0.4325\times 10^{-2})^2\times 0.051=3\times 10^{-6}m^3$

It is given there is uniform magnetization of $M=5.17\times 10^3A/m$

We have to fond the dipole moment

Dipole moment is equal to $\mu =MV$ , here M is magnetization and V is volume

So $\mu =MV=5.17\times 10^3\times 3\times 10^{-6}=15.51\times 10^{-3}J/T$

An 1647 w toaster, a 1592 w electric frying pan, and a 81 w lamp are plugged into the same outlet in a 120-v circuit. (the three

yanalaym [24]

Since all of the appliances ... and everything else in the house that's
plugged into a wall outlet ... are all in parallel, they don't have any
effect on each other. They don't know about each other. The
question asks about the frying pan, so the toaster and the lamp
have no effect on the answer.

The frying pan has 120 V applied to it, and it produces 1592 watts
of heat.

Power = (voltage)·(current)

1592 watts = (120 v)·(current)

Divide each side by 120v:

Current = (1592 watts) / (120 volts)

Current = 13.27 Amperes

m = A kg
h = U ÷ mg
= 400÷10A
= 40÷A
