What color will a star be with a surface temperature of 5000–6000 K?

Physics

Answer:

C. yellow

Explanation:

The stars have different color depending on their temperature, in general the more blue or violet a star is, the higher its surface temperature, and the more orange or red, the lower its surface temperature.

In the stellar classification, stars with temperatures ranging from 5000K to 6000K are G type stars which are characterized by having a yellow color.

An example of a G-type star is the sun, which has a surface temperature of around 5700K.

Explain how it is that you could have 2 parents with brown eyes, but you have blue eyes. Talk about the role chromosomes, genoty
steposvetlana [31]

Answer:

If both parents had a recessive allele for blue eyes and they had a brown phenotype it is completely possible for the child to have blue eyes.

Explanation:

Chromosomes play the role of transfering the encoded strands of DNA to the child. Genotypes are the traits or groups of traits transferred and need to carry the trait of blue eyes in order for the child to have them. As long as the parents had a recessive allele for blue eyes they could have a blue eyed child.

If an atom has 15 protons, 12 neutrons, and 17 electrons, what is the atom's electrical charge? A. -5 B. -2 C. +3 D. +5
Nimfa-mama [501]

Answer:

B. -2

Explanation:

The total charge on an atom is the sum of all individual charges present in it. Therefore, the total charge on this atom is given by the following formula:

q = (n_p)(q_p)+(n_e)(q_e)+(n_n)(q_n)

where,

q = total charge on atom = ?

n_p = no. of protons in the atom = 15

n_e = no. of electrons in the atom = 17

n_n = no. of neutrons in the atom = 12

q_p = charge on proton = +1

q_e = charge on electron = -1

q_n = charge on neutron = 0

Therefore,

q = (15)(1)+(17)(-1)+(12)(0)\\q=-2

Hence the correct option is:

<u>B. -2</u>

Why do we experience a high tide twice a day?
Veseljchak [2.6K]

Coastal areas experience two low tides and two high tides every lunar day, or 24 hours and 50 minutes. The two tidal bulges caused by inertia and gravity will rotate around the Earth as the moons position changes. These bulges represent high tides while the flat sides indicate low tides.

Over the course of 1 day, the position of the moon does not change very much compared to the rotation of the earth. As the earth rotates below the moon, one point on the earth will go through all levels of tide as the day passes by. Strongly attracted, middling, weakly attracted, and then middleagain. From our perspective it looks like "high, low, high, low." Or equivalently you can think about how the points below the moon and opposite the moon will be high tide, and as the earth rotates, those areas will change.
