Answer:

Atoms are electrically neutral because there are an equal number of protons in the nucleus and In the cloud around the nucleus.

Explanation:

The atoms that are the building block of matter consist of protons, neutrons, and electrons.
The protons are positively charged and the electrons are negatively charged particles.
The neutrons are negatively charged particles.
The atoms in its stable natural state consist of an equal number of protons and electrons.
Thus an atom has a neutral charge in its natural state.

Your little sister is building a radio from scratch. Plans call for a 500 μH inductor wound on a cardboard tube. She brings you

gayaneshka [121]

Answer:

N = 195 turns

Explanation:

The inductance of the inductor, L = 500 μH = 500 * 10⁻⁶H

The length of the tube, l = 12 cm = 0.12 m

The diameter of the tube, d = 4 cm = 0.04 m

Radius, r = 0.04/2 = 0.02 m

Area of the tube, A = πr² = 0.02²π = 0.0004π m²

$\mu_{0} = 4\pi * 10^{-7}$

The inductance of a solenoid is given by:

$L = \frac{\mu_{0}N^{2} A }{l}$

$500 * 10^{-6} = \frac{4\pi *10^{-7} N^{2} *4\pi *10^{-4} }{0.12}\\500 * 10^{-6} = 0.00000001316N^{2} \\N^{2} = \frac{500 * 10^{-6}}{0.00000001316}\\N^{2} = 37995.44\\N = \sqrt{37995.44} \\N = 194.92 turns$

An inclined plane is 10.0 m long and 2.5 m high. What is the mechanical advantage?

igomit [66]

Answer:

MA = 4

Explanation:

In order to solve this problem, we must use the definition of the ideal mechanical advantage, which tells us that it is equal to the relationship of the inclined distance over the height with respect to the level of the ground

MA = L / h

where:

MA = mechanical advantage

L = Length of the inclined plane = 10 [m]

h = elevation = 2.5 [m]

MA = 10/2.5

MA = 4
