A solenoid with 3,000.0 turns is 70.0 cm long. If its self-inductance is 25.0 mH, what is 5) its radius? (The value of o is 4 ×

Elan Coil [88]

The self-inductance of a solenoid is given by:
$L= \frac{\mu_0 N^2 A}{l}$
where
$\mu_0$ is the vacuum permeability
N is the number of turns
A is the cross-sectional area of the solenoid
l is the length of the solenoid

For the solenoid in our problem, N=3000, l=70.0 cm=0.70 m and the self-inductance is L=25.0 mH=0.025 H, therefore the cross-sectional area is
$A= \frac{Ll}{\mu N^2}= \frac{(0.025 H)(0.70 m)}{(4\pi \cdot 10^{-7}N/A^2)(3000)^2}= 1.55 \cdot 10^{-3}m^2$
And since the area is related to the radius by
$A=\pi r^2$
The radius of the solenoid is
$r= \sqrt{ \frac{A}{\pi} } = \sqrt{ \frac{1.55 \cdot 10^{-3} m^2}{\pi} } =0.022 m=2.2 cm$

Describe electronegativity, and explain the trend of electronegativity in the Periodic Table

vaieri [72.5K]

Explanation:

Electronegativity is the property of an atom that attracts the shared pair of an electron to itself. There is a trend in the periodic table.

While moving down in a group, the electronegativity decreases. This is due to the reason that as we move down the number of shells added and so the electron become very far from the pull of the nucleus.

As we move across a period the electronegativity increases. This is because of the no. of charge on the nucleus increase.

Galileo challenged the idea that objects in the heavens were perfect by ________.

DENIUS [597]

Answer:

d. observing sunspots on the Sun and mountains on the Moon

Explanation:

Galileo was an Italian Physicist and Astronomer and is regarded as the father of modern Physics.

It was previously believed that the objects in the heavens such as the sun, moon and stars were perfect and rough till he observed sunspots on the sun and mountains on the moon which indicates the surface of the moon is rough with mountains and craters.
