Irregular galaxies are very large. True or False?

Physics
2 answers:
AleksandrR [38]3 years ago
6 0

Answer:

False , irregular galaxies are not large galaxy.

Explanation:

False , irregular galaxies are not large galaxy.

There is no specific shape of irregular galaxies. They are one of the tiniest galaxies, filled with gas and dust. Having lots of dust and gas means there's a lot of star formation heading at these galaxies. This process can make them very clear. some examples of these type of galaxies are the Major and minor Magellanic Clouds.

A long, straight wire is surrounded by a hollow metal cylinder whose axis coincides with that of the wire. The wire has a charge
Alexxx [7]

Explanation:

It is given that, a long, straight wire is surrounded by a hollow metal cylinder whose axis coincides with that of the wire.

The charge per unit length of the wire is \lambda and the net charge per unit length is 2 \lambda.

We know that there exist zero electric field inside the metal cylinder.

(a) Using Gauss's law to find the charge per unit length on the inner and outer surfaces of the cylinder. Let \lambda_i\ and\ \lambda_o are the charge per unit length on the inner and outer surfaces of the cylinder.

For inner surface,

\phi=\dfrac{q_{enclosed}}{\epsilon_o}

E.A=\dfrac{q_{enclosed}}{\epsilon_o}

0=\dfrac{\lambda_i+\lambda}{\epsilon_o}

\lambda_i=-\lambda  

For outer surface,

\lambda_i+\lambda_o=2\lambda

-\lambda+\lambda_o=2\lambda

\lambda_o=3\lambda

(b) Let E is the electric field outside the cylinder, a distance r from the axis. It is given by :

E_o=\dfrac{\lambda_o}{2\pi \epsilon_o r}

E_o=\dfrac{3\lambda}{2\pi \epsilon_o r}

Hence, this is the required solution.

Which of these is an example of electrical energy being converted to mechanical energy?
GalinKa [24]

Answer:

Ceiling fan

Explanation:

Ceiling fan is a perfect and typical example of electrical energy being converted to mechanical energy.

In most systems, energy is usually transformed from one form to another. Energy is not created neither is it destroyed. We know this by virtue of law of conservation of energy.

  • The ceiling fan is powered by electrical energy from an outlet.
  • The energy from the outlet is used to drive the blades of the fan and set them into motion.
  • This is mechanical energy.
