Select the reasons why most professional telescopes are reflectors rather than refractors.
a) A lens has to be supported only around its edges.
b) Only the front surface of a mirror has to have a precise shape.
c) Reflecting telescopes have shorter focal lengths than refracting telescopes.
d) It is easier to make a large reflecting telescope than a large refracting telescope.
e) Lenses are not subject to chromatic aberration.
f) A reflector can collect more light than a refractor.
Answer:
d). It is easier to make a large reflecting telescope than a large refracting telescope.
f). A reflector can collect more light than a refractor.
Explanation:
A telescope is a device that is used to observe distant objects by the use of lenses and mirrors. It is also used to observe different distant objects by their reflection, absorption, emission or the reflection of the electromagnetic radiations.
Most of the professional telescopes are reflectors because :
1. The reflected telescope is able to receive more of the light when it reflects all the light falling on surface. And it is easier for making a large telescope rather then making large lenses for the refracting telescope. So it is easier to make large reflecting telescope than a large refracting telescope.
2. A reflected telescope receives all the wavelength of the light and it reflects all the light falling on the surfaces where it is refracted telescope that contains lenses cannot absorbs all the light and causes the chromatic aberration.
It is simpler to make a large reflecting telescope than have a large refracting telescope. A reflector can collect more light than a refractor. Hence the options D and F are correct.
What are professional telescopes ?A telescope is an optical instrument that is used for seeing far objects from a distance and includes the measures for the various distances that can be used to see through the device. The light that is emitted, absorbed, and reflected can be seen through the electromagnetic radiation can be observed through the refracting lens of the telescope.

What season is the Northern Hemisphere experiencing?
O spring
O winter
O autumn
O summer
The correct answer is C. Autumn.
Explanation
During the orbit of the Earth on its inclined axis around the Sun there are four main positions that means four different periods throughout the year: they are the solstices and the equinoxes. These periods are also known as the spring, summer, autumn, and winter seasons. Each season of the year has its characteristics concerning temperature, rainfall, and sunlight, among other characteristics. The image shows the sun to the left of the earth, so it can be said that it is in the position of the equinox on September 23. In this position, the northern hemisphere is in autumn and the southern in spring. So the correct answer is C. Autumn.
Find the area of the figure.
Answer:
132 cm²
Explanation:
The figure can be decomposed into a rectangle and a trapezoid
Area of the figure = area of the rectangle + area of the trapezoid
= L*W + ½(a + b)*h
Where,
L = 7 cm
W = 4 cm
a = 7 cm
b = 19 cm
h = 8 cm
Area of the figure = 7*4 + ½(7 + 19)8
= 28 + ½(26)8
= 28 + 104
= 132 cm²

The fuel oils and coal are classified as
Fossil fuels include coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils. All contain carbon and were formed as a result of geologic processes acting on the remains of organic matter produced by photosynthesis, a process that began in the Archean Eon (4.0 billion to 2.5 billion years ago).
Coal, petroleum, natural gas, oil shale, bitumen, tar sands, and heavy oils are examples of fossil fuels.
All of them include carbon and were created by the action of geologic processes on organic material left over after photosynthesis, a process that started in the Archean Eon (4.0 billion to 2.5 billion years ago).
Explain what are coal and petroleum?
Ancient plant life that existed millions of years ago is what causes coal and petroleum to form. Plant remains began to assemble, creating a material known as peat.
These minerals were gradually converted into coal and petroleum by the heat and pressure of geological processes throughout time.
Coal, petroleum, and natural gas are examples of finite natural resources that were created from the decayed remains of living things (fossils). These are referred to as fossil fuels.
Petroleum and coal are two highly important natural resources that are essential to contemporary society. They are located in the crust of the earth.
