Reflecting telescope. Reflecting telescopes tend to have larger objective (due to the use of mirrors, mirrors are a lot cheaper than lenses) and have the ability to collect more light, while refracting telescopes are limited to objective lenses with smaller diameters due to their structural limitations (chromatic abbreviation, for example). Therefore, reflecting telescopes should be better at viewing faint distant stars

How much work done when .0080 C is moved through a potential difference of 1.5 V? Use W = qV. A.

grin007 [14]

Answer:

0.012 J

Explanation:

We are given:

q = 0.0080C

Potential difference = 1.5V

W=qV

Substituting the values into the equation:

W=0.0080*1.5= 0.012J

What was the first evidence that gravity outside our solar system worked the same way as it does inside?

Julli [10]

The first evidence that gravity outside our solar system worked the same way as it does inside is that Herschel measured the two stars that make up the Castor system moved around each other

<h3>What is a Solar system ?</h3>

The Sun, eight planets, their moons, comets, asteroids, meteoroids, and dwarf planets make up a solar system, which revolves around the Sun. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are the eight planets that revolve in a particular order around the Sun.

Although there are more than 3,200 other stars in our galaxy with planets around them, our solar system is the only one that is formally referred to as a "solar system."

The closest stellar system to our solar system, Alpha Centauri, is one of the brightest stars in the southern skies and is only 4.3 light-years away.

The amount of sea ice and permafrost have steadily decreased near Shishmaref, Alaska, over the last century. The loss of ice has

Dovator [93]

Answer:

Climate change, where there is an increase in the average temperature, due to continuous human activities. These activities increase greenhouse gases in the atmosphere.

Explanation:

Alaska is the largest state in the United States, and it has a cold climate. The climate changed over time as human activities such as coal mining contributed to greenhouse gas emissions leading to global warming. Over the years. the variations in weather leading to climate change melt the permafrost (frozen ground below the soil surface) causing ocean waves to erode the land and destroy property.

A NASA explorer spacecraft with a mass of 1,000 kg takes off in a positive direction from a stationary asteroid. If the velocity

Georgia [21]

Answer: 10000 kg

Explanation:

The momentum $p$ is given by the following equation:

$p=m.V$ (1)

Where:

$m$ is the mass of the object

$V$ is the velocity of the object

Now, in this case and according the conservation of momentum:

$m_{1}v_{1}+m_{2}v_{2}=m_{1}u_{1}+m_{2}u_{2}$ (2)

Where:

$m_{1}=1000kg$ is the mass of the spacecraft

$m_{2}$ is the mass of the asteroid

$v_{1}=0$ is the initial velocity of the spacecraft

$v_{2}=0$ is the initial velocity of the asteroid (because we are told the asteroid is stationary, as the spacracft is on the sateroid it remains stationary as well)
