At the summit, the temperature can drop to -73° Celsius below zero. But on a sunny summit day, you temperatures can go as high as around -26C
Answer:
find minerals for either use or for economics
Answer:
The black hole in the nucleus of the Milky Way Galaxy could not be the remnant of a single dead star.
Explanation:
The very center of the galaxy is known as the nucleus of the galaxy. The nucleus of the galaxy is hidden due to the dust particles present in the galaxy, which eventually covers the light of the nucleus.
The nucleus of the galaxy is filled with numerous stars and dust and the radiation emitted by them. The black hole lies at the center of the galaxy.
<u>These super-massive black holes could not be the remnant of a single dead star because these holes are very large.</u>
So, the correct answer is no.
Answer:
See explanation below:
Explanation:
Transit Photometry is the most widely-used and effective to date, it has been a method that measures the light curve of distant stars for periodic dips in brightness. These are the result of exoplanets passing or transiting in front of the star relative to the observer. It is currently the most effective and sensitive method for detecting extrasolar planets, particularly from an observatory in space. When combined with radial velocity data, a transit can also provide a good estimate of the planet's mass. This method detects distant planets by measuring the minute dimming of a star as an orbiting planet passes between it and the Earth.
The main reason direct detection of exoplanets is difficult is because most planets orbit planets orbit at small angular separations on the sky, this means a direct detection is only possible if the star's light can be suppressed or occulted such that the faint light from the planet can be detected.
Some planets are found via the wobble method, using both methods, combining mass and size, scientists can calculate the planet's density, an important step towards assessing its composition.
C) i would answer this, because it makes more sense
