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.
Answer:
Line OX = 7.09
Explanation:
The question is incomplete. Find attached the complete question.
SOLUTION
Given:
Line OL is perpendicular to DX
Line DX = 13
Line PO = the hypotenuse of the larger triangle
Line PO = 10
Line BO = hypotenuse of smaller triangle
Line BO = 12
To find length of line OX, we would apply rule of similar and congruent triangles.
∆DPO = ∆XBO
<POD = <BOX
Line DP is parallel to line XB
Since length of side DX = 13
Side DX = side DO + side OX
Let side DO = x
Side OX = 13-x
(Adj of ∆DPO)/(Adj of ∆XBO) = hyp of ∆DPO/hyp of ∆XBO
DO/OX = PO/BO
x/ (13-x) = 10/12
12x = 10(13-x)
12x = 130-10x
12x +10x = 130
22x = 130
x = 130/22 = 65/11
x is approximately = 5.91
Therefore line OX = 13 - 5.91
Line OX = 7.09
Answer:
The Earth rotates about an imaginary axis that passes two different poles. ... So, the equator experience more angular speed that tries to pull off the part of the Earth from the rotational axis. Hence the equator of the Earth is wider and bulge. The rotation of the Earth about its own axis affects the shape of the Earth.
