How is high temperature achieved in solar power plant by the use of mirrors?

An object 5 cm high is placed at a distance of 10cm from a convex mirror whose radius of curvature is 30 cm. Find the nature, position and size of the image.

A ray of light is incident at ${60}^{\circ }$ on glass-air interface. Find out the total deviation of the ray?

In an LCR series circuit, R = 200Ω and the voltage and frequency of the main supply is 220V and 50 Hz respectively. On taking out the capacitance from the circuit, the current lags behind the voltage by ${30}^{\circ }$. On taking out the inductor from the circuit, the current leads the voltage by ${30}^{\circ }$. The power dissipated in the circuit is

We say that gravitational potential energy is zero when the object is on the ground(earth surface). My doubt is that can gravitational potential energy be considered zero anywhere (at any altitude) when object is kept on the surface of earth? And also there is distance between the object and the centre of the earth, how can the gravitational potential energy be considered zero?

What is magnetic field line and its properties.

What are baryons and leptons?How are they both conserved?

A prism has refracting angle equal to $\pi /2.$ It is given that $\gamma$ is the angle of minimum deviation and $\beta$ is the deviation of the ray entering at grazing incidence.

Choose the correct relation.

A couple consists of

Day
by day the nightingale

Grew
more sorrowful and pale.

Night
on night her tired song

Zipped
and trilled and bounced along,

Till
the birds and beasts grew tired

At
a voice so uninspired

And
the ticket office gross

Crashed,
and she grew more morose -

For
her ears were now addicted

To
applause quite unrestricted,

And
to sing into the night

All
alone gave no delight.

The
audience was tired of her song because

1.
they had heard it many times

2.
it had become mechanical

3.
she looked tired

4.
she had added trill to her song
