Answer:

The way that technology impacts the environment are:

Positive:

It can be used to develop better processes of employing non-renewable fuel resources.

It can be employed to research ways to reduce the cost of the employment of renewable resources to create energy out of them and contribute to the replacement of non-renewable ones.

Negative:

Since the industrial revolution, technology was used to produce wealth becoming the most important action for societies.

Scientists use non-renewable energy resources to create new technology and at the same time that technology used non- renewable resources to work, without worrying about the impact.

Explanation:

Technology impacts positively the environment because in the first please it allows us to develop cleaner non-renewable energies because of the research performed on them. In the second place by researcher ways to reduce the cost of production of renewable sources of energy. However, it also negatively impacts the environment. The first one is that since the industrial revolution the world turned itself to a monetary perspective in which create wealth and produce goods is more important than anything else. So, technology was created to industrialize the processes of production without worrying about the environment. And in second place because the technological advancement many times uses resources that are non-renewable and scientists release them as patents to make money out of them instead of being environmentally responsible.

Negative:
plants and animals risk habitat loss as they have had exposure to dangerous byproducts of technology.
if someone creates something dangerous, then humans can inhale harmful chemicals in air pollution and it also consumes resources that are non-renewable
positives:
you can use technology to help the environment, through the use of recycling, purification of water and air to prevent pollution and contamination. for the second one you could say that technology has stopped the habitats from dying 

hope this helps in some way :)

What is the main cause of twice-daily tides around the world?<br><br><br> Help me.
liraira [26]

<em>The main cause of twice-daily tides around the world are;</em>

Gravitational pull of the moon

<u>Tides are the rise and fall of water caused by gravitational forces of the moon and sun on the oceans of the earth. </u>

<u>The moons gravity is large enough to actually pull water out of the ocean from space. Just enough to create motion of the tides.</u>

The James Webb Space Telescope is positioned around 1.5 million kilometres from the Earth on the side facing away from the Sun.
Bad White [126]

The angular velocity depends on the length of the orbit and the orbital

speed of the telescope.

Response:

First question:

  • The angular velocity of the telescope is approximately <u>0.199 rad/s</u>

Second question:

  • The telescope should accelerates away by approximately F = <u>0.0005·m </u>

Third question:

  • <u>The pulling force between the Earth and the satellite</u>

<h3>What equations can be used to calculate the velocity and forces acting on the telescope?</h3>

The distance of the James Webb telescope from the Sun = 1.5 million kilometers from Earth on the side facing away from the Sun

The orbital velocity of the telescope = The Earth's orbital velocity

First question:

Angular \ velocity = \mathbf{\dfrac{Angle \ turned}{Time \ taken}}

The orbital velocity of the Earth = 29.8 km/s

The distance between the Earth and the Sun = 148.27 million km

The radius of the orbit of the telescope = 148.27 + 1.5 = 149.77

Radius of the orbit, r = 149.77 million kilometer from the Sun

The length of the orbit of the James Webb telescope = 2 × π × r

Which gives;

r = 2 × π × 149.77 million kilometers ≈ 941.03 million kilometers

Therefore;

Angular \ velocity = \dfrac{29.8}{941.03}\times 2 \times \pi \approx 0.199

  • The angular velocity of the telescope, ω ≈ <u>0.199 rad/s</u>

Second question:

Centrifugal force force, F_{\omega} = m·ω²·r

Which gives;

F_{\omega} = m \cdot \dfrac{28,500^2 \, m^2/s^2}{149.77 \times 10^9 \, m} \approx 0.0054233 \cdot m

Gravitational \ force,  F_G = \mathbf{G \cdot \dfrac{m_{1} \cdot m_{2}}{r^{2}}}

Universal gravitational constant, G = 6.67408 × 10⁻¹¹ m³·kg⁻¹·s⁻²

Mass of the Sun = 1.989 × 10³⁰ kg

Which gives;

F_G = 6.67408 \times 10^{-11} \times \dfrac{1.989 \times 10^{30} \times m}{149.77 \times 10^9} \approx   0.00592 \cdot m

Which gives;

F_{\omega} < F_G, therefore, the James Webb telescope has to accelerate away from the Sun

F = \mathbf{F_{\omega}} - \mathbf{F_G}

The amount by which the telescope accelerates away is approximately 0.00592·m - 0.0054233·m ≈ <u>0.0005·m (away from the Sun)</u>

Third part:

Other forces include;

  • <u>The force of attraction between the Earth and the telescope </u>which can contribute to the the telescope having a stable orbit at the given speed.
