Which type of telescope focuses star light using mirrors?

Physics
1 answer:
Tatiana [17]3 years ago
7 0

Coudé telescopes use a convex secondary mirror like a Cassegrain and an angled mirror like a Newtonian reflector to move the light rays to a focal point away from the telescope. This arrangement is useful when optical equipment is being used that is too heavy to mount directly on the telescope.

Which of these will cause the highest tides? A. when the Sun, Moon and Earth are in a straight line B. when all of the planets a
marusya05 [52]

Answer:

A. when the Sun, Moon and Earth are in a straight line

Explanation:

The highest tide is formed when the sun, moon, and also the earth are in alignment. This high tide is known as spring tides.

Spring tides happen when we have a new moon or a full moon. With the earth, sun and moon aligning. We have lunar and solar tide forming a reinforcement with each other causing high tides or extreme tides. we have collectively, their gravitational pull on water of the earth to become stronger

We often see cracks on rocks and stones why
Paul [167]

Answer:

Due to the process of weathering and erosion.

Explanation:

  • As the rocks are made of different forms of minerals they may have an igneous, metamorphic or sedimentary origin. Hence the natural stone surfaces can be made of granite, lime, or even shale.  
  • The process of physical weathering that is called as mechanical weathering of rocks tends to break them apart and leads to the development of crack and small openings.
  • The diurnal exposure of bare rocks to extreme temperatures of day and night leads to onion peeling and slowly with water as an agent of erosion lead to cracks in joints of rocks.

How does the way that matter cycles through an ecosystem differ from the way that energy flows?
guapka [62]

Unlike the one-way flow of energy, matter is recycled within and between ecosystems. Every living organism needs nutrients to build tissues and carry out essential life functions.

Water is flowing into a factory in a horizontal pipe with a radius of 0.0183 m at ground level. This pipe is then connected to a
timama [110]

Answer:

0.0168 m^3/s

Explanation:

We are given that

r_1=0.0183 m

h_1=0

r_2=0.0420 m

h_2=12.6 m

Let P_1=P_2=P

By using Bernoulli theorem

P+\frac{1}{2}\rho v^2_1+\rho gh_1=P+\frac{1}{2}\rho v^2_2+\rho gh_2

\frac{1}{2}\rho v^2_1+\rho gh_1=\frac{1}{2}\rho v^2_2+\rho gh_2

v^2_1+2gh_1=v^2_2+2gh_2

A_1v_1=A_2v_2

v_1=\frac{A_2v_2}{A_1}

(\frac{A_2}{A_1})^2v^2_2+2g\times 0=v^2_2+2\times 9.8\times 12.6

(\frac{\pi r^2_2}{\pi r^2_1})^2v^2_2-v^2_2=246.96

v^2_2((\frac{r^2_2}{r^2_1})^2-1)=246.96

v^2_2=246.96\frac{r^4_1}{r^2_4-r^4_1}

v_2=\sqrt{246.96\frac{r^4_1}{r^4_2-r^4_1}}

v_2=\sqrt{246.96\times \frac{(0.0183)^4}{(0.042)^4-(0.0183)^4}}

v_2=3.038 m/s

Volume flow rate =A_2v_2

Volume flow rate =\pi r^2_2v_2=\pi (0.042)^2\times 3.038=0.0168 m^3/s
