Explanation:

English Translation of Question

1) How do we mark the focus on the main optical axis? Select the correct answer. *

A) Option A is F

B) S

C) f

D) O

The focus for a spherical mirror is marked along the optical axis of the spherical mirror at half the distance between the centre of the sphere that the mirror was cut from and the actual mirror.

Option A is correct.

The focus is normally marked as letter F on the optical axis.

2) What is the radius of curvature? Select the correct answer. *

A) half focal length

B) Double focal length

C) Radius of

D) focal length

The radius of curvature is the radius of the sphere from which the spherical mirror was cut. It measures the distance from the centre of curvature to the actual mirror along the optical axis.

Since the distance from the focus of the mirror to the mirror along the optical axis is the focal length, the radius of curvature is twice the focal length.

Option B is correct.

The radius of curvature is double the focal length.

3) What is focal length? Select the correct answer. *

A) Distance of the object from the mirror

B) Distance of the image from the mirror

C) Distance of the mirror from the focus

D) Distance of the object from the image

The distance from the focus of the mirror to the mirror alomg the optical axis is the focal length.

Option C is correct.

Focal length is distance of the mirror from the focus.

4) What is a shadow? Select the correct answer *

A) Image created on canvas.

B) A dark spot on the Sun A

C) place where light reaches in a limited amount

D) Area behind the object

A shadow is defined as a dark area which is a real image, where light from a light source is blocked by an opaque object.

Option C is correct.

A shadow is a place where light reaches in a limited amount.

5) What is a mirror? Select the correct answer. * A

A) flat surface painted with paint A

B) flat, polished surface A

C) flat, rough surface on which the light is scattered

D) Rough surface

A mirror is defined as flat, polished surface that reflects light rays.

Option B is correct.

A mirror is a flat, polished surface A.

6) Where is the real image created in spherical mirrors? Select the correct answer. *

A) On the opposite side to the item

B) On the same side as the item

Only concave mirrors and convex lenses produce real images. Real images are as a result of actual light rays. They are normally also inverted. And they usually form in between the object and the mirror for concave mirrors.

Option B is correct.

Real images are created on the same side as the item for spherical mirrors.

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
