Answer:
The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. The motion of the three bones causes the fluid in the inner ear, or cochlea, to move.

The sound waves go through the ear canal into the middle ear, which includes the eardrum (a thin layer of tissue) and three tiny bones called ossicles. The sound causes the eardrum to vibrate. The ossicles amplify these vibrations and carry them to the inner ear.
The sun is approximately 27,000 light years away from the center of our galaxy.
A nuclear power plant is defined as a thermal power station where electricity is generated by the help of sustainable nuclear fission.
A nuclear power plant needs nuclear reactor as the thermal energy generator .The reactor has various parts where fissionable radioactive material will undergo nuclear fission .Through this process high amount of thermal energy is released which is allowed to water to generate steam.
The steam produced in the reactor drives the turbine which is connected to the generator.Due to the electromagnetic induction the generator will produce electricity.
The control rods present in the nuclear reactor will control the rate of fission by absorbing the thermal neutrons.
Hence the correct answer of the question is C i.e Turbine.
According to the question, the object is placed at 2F
The ray diagram is shown in the figure attached.
According to the figure:
Object AB is at 2F₁
First, we draw a ray parallel to principal axis.
So, it passes through focus after refraction.
We draw another ray which passes through optical center.
So, the ray will go through without any deviation.
Where both refracted rays meet is point A' and the image formed is A'B'
This image is formed at 2F₂
We can say that:
- Image is real.
- Image is inverted.
- Image is exactly the same size as the object.
Because the hamburger is still hot from the grill, the cheese melts because of that heat.
