image distance,di=10 cm

object distance,do=20cm

magnification, m=di/do

=10/20

=0.5

since the image is virtual, magnification is negative.

therefore m=-0.5

A long, hollow wire with inner radius a and outer radius b carries a uniform current density J. What is the magnetic field as a
sveta [45]

Answer:

The magnetic field in the region a < r < b is B=\frac{u_{0}I(r^{2}-a^{2})   }{2\pi r(b^{2}-a^{2})  }

Explanation:

If we have the a < r < b. The formula of current is:

J=\frac{I_{total} }{A}

Where:

A = area enclosed by the loop.

Itotal = total current in loop.

J=\frac{I}{\pi b^{2}-\pi  a^{2} }

I_{enclosed} =JA_{enclosed}

I_{enclosed} =\frac{I(\pi r^{2}- \pi a^{2})}{\pi b^{2}-\pi a^{2}  }

If we have the Ampere`s law:

\int\limits^a_b {B} \, ds  =u_{0} I_{enclosed} \\2B\pi r=u_{0} (\frac{I(\pi r^{2}-\pi  ^{2} }{\pi ^{2}-\pi  a^{2} } )\\B=\frac{u_{0}I(r^{2}-a^{2})   }{2\pi r(b^{2}-a^{2})  }

Marina is staring at an optical illusion where he sees a version of the American flag that is colored green, yellow, and black.
k0ka [10]

Explanation:

The reason why Marina sees the colour red, white and blue or the original colour of the American flag is that because of a phenomenon known as Afterimage. The retina in our eyes have mainly three receptors that are colour sensitive known as cones. These receptors can perceive the colour green, red and blue. Now when we look or stare at a particular colour for a long time, what happen is that our retina becomes tired and they ignore the colours that stared at. And now they work to form other colours at the retina just like the way when we produce other colour from the primary colour.

If the red receptor gets exhausted we will see the colour red. Likewise when we see the colour orange when we stare at the colour blue.

This explains the optical illusion of the American flag.

A family has a furnace that uses natural gas to heat their home. They are moving to an area that offers the option of using ener
Murrr4er [49]

The disadvantage will the family most likely face by making this switch is that solar power has a less reliable production of heat.Option A is correct.

<h3>What is a power plant?</h3>

A power plant is an industrial structure that generates electricity. The majority of power plants are linked to the electrical grid.

Nuclear power bare a form of the thermal power plant. You have a reactor where fission takes place and heat is generated, a heat exchanger that transports this heat to where it is needed.

Thermal power plant equipment converts this heat into electric energy, usually via a steam turbine.

The household will most likely experience a disadvantage from this decision in that solar power produces heat less consistently.

Hence option A is correct,
