Answer: C

Telescope

Explanation: A telescope is an optical device in which scientists ( astronomers) use to view far away distance objects in the universe.

The single invention of the telescope has advanced what we know about the universe more than any other scientific technology. Because with the use of telescope alone, astronomers could view and study many heavenly objects or bodies and many planets in the universe.

The optical instrument makes very far distant objects appear magnified by using an arrangement of lenses or curved mirrors and lenses for clearer viewing of heavenly objects and planets in our universe.

Through what process is carbon pulled from the atmosphere in the carbon cycle
Andrei [34K]

Carbon is pulled from the atmosphere in the carbon cycle through the process of photosynthesis. Details about photosynthesis can be found below.

<h3>What is photosynthesis?</h3>

Photosynthesis is the process whereby green plants obtain their nutrition by utilizing energy from sunlight.

Green plants absorb carbon in the form of carbon dioxide from the atmosphere and use it in the photosynthetic process.

This means that one way that carbon is removed from the atmosphere during the carbon cycle is through photosynthesis.

If the block is subjected to the force of F = 500 N, determine its velocity at s = 0.5 m. When s = 0, the block is at rest and t
STatiana [176]

Answer:

The velocity is  4.6 m/s^2

Explanation:

Given:

Force = 500N

Distance  s= 0

To find :

Its velocity at s = 0.5 m

Solution:

\sum F_{x}=m a

F\left(\frac{4}{5}\right)-F_{S}=13 a

500\left(\frac{4}{5}\right)-\left(k_{s}\right)=13 a

400-(500 s)=13 a

a = \frac{400 -(500s)}{13}

a = (30.77 -38.46s) m/s^2

Using the relation,

a=\frac{d v}{d t}=\frac{d v}{d s} \times \frac{d s}{d t}

a=v \frac{d v}{d s}

v d v=a d s

Now integrating on both sides

\int_{0}^{v} v d v=\int_{0}^{0.5} a d s

\int_{0}^{v} v d v=\int_{0}^{0.5}(30.77-38.46 s) d s

\left[\frac{v^{2}}{2}\right]_{0}^{2}=\left[\left(30.77 s-19.23 s^{2}\right)\right]_{0}^{0.5}

\left[\frac{v^{2}}{2}\right]=\left[\left(30.77(0.5)-19.23(0.5)^{2}\right)\right]

\left[\frac{v^{2}}{2}\right]=[15.385-4.807]

\left[\frac{v^{2}}{2}\right]=10.578

v^{2}=10.578 \times 2

v^{2}=21.15

v = \sqrt{21.15}

v = 4.6 m/s^2

How is Newton’s third law of motion involved when you jump straight upward?
Bad White [126]
<span>Newtons 3rd law of motion states that action and reaction are equal and opposite. How it applies in this statement is that when you jump straight upward you hit the floor and you experience an equal magnitude of force against your feet, because force always acts as a result of two objects and whenever forces occur they do so in pairs of equal magnitude acting in opposite directions. I hope this helps!</span><span>

"Whereas the velocity of a wind-blown wave can be calculated if you know its wavelength, what piece of information do you need t
Artist 52 [7]

Answer: Frequency

Explanation: The velocity of a wave is the product of wavelength and frequency. That is to say:

v=\lambda\cdot{f}

Hence, the frequency associated with the tsunami is needed to calculate the velocity.
