Describe a young star.
Devils Tower is primarily made of a greenish rock called phonolite. The Giant's Causeway is made of a black rock called basalt.
green rock with flecks of white and red and fine-grained black rock
Compare the appearance of the two rocks. What do their appearances suggest about the composition of each rock?
Answer:
One of the rocks seems to be made of more than one mineral. This could suggest that it is a METAMORPHIC rock. Basalt would be an IGNEUS rock! Hope this helped!

What is the life span of our sun?
What is the life span of stars larger than the sun?
Answer:
What is the life span of our sun?
Stars like our Sun burn for about nine or 10 billion years. So our Sun is about halfway through its life. But don't worry. It still has about 5,000,000,000—five billion—years to go.
What is the life span of stars larger than the sun?
Stars live different lengths of time, depending on how big they are. A star like our sun lives for about 10 billion years, while a star which weighs 20 times as much lives only 10 million years, about a thousandth as long.
Explanation:
Why can't a volume of water be compressed or expanded like a volume of air in a closed syringe system?
Answer:
It is all about pressure. When you plug upon the nozzle, there is no way for the pressure of the fluid to rise above a certain value, so pushing in is opposed by the fluid pushing back on your finger, it gets hard! However, if you open the valve and allow fluid to squeeze out, then the pressure can be relieved a bit and that allows you to keep the piston moving down. That is applying an unbalanced force that allows the fluid to accelerate from zero velocity inside the barrel to some higher velocity through the nozzle.

(The picture shows a child sliding down a plastic slide.)
Which statement best describes why the child's hair stands up after he slides down the slide?
A) Friction caused a transfer of electrons between the slide and the child, making each of his like-charged hairs repel each other.
B) Energy was transferred from the slide to the child through induction, causing the child's hair to become charged and stand up.
C) Energy was transferred from the child to the slide through conduction, causing the child's hair to become charged and stand up.
D) Friction caused a transfer of electrons between the slide and the child, making his like-charged hairs attract the air through induction.
Answer:
Your answer is A: Friction caused a transfer of electrons between the slide and the child, making each of his like-charged hairs repel each other.
Explanation:
The most likely explanation for why the child's hair stands up after sliding down the slide is due to the transfer of electrons caused by friction between the slide and the child's hair. Hence, option A is correct.
Why does the child's hair stand up after sliding down the slide?When the child slides down the slide, there is friction between the slide and the child's hair. This friction causes a transfer of electrons between the two surfaces, with electrons moving from one surface to the other.
This transfer of electrons can result in the child's hair becoming negatively charged, which causes the individual hairs to repel each other, leading to the hair standing up.
Therefore, the correct answer is A Friction caused a transfer of electrons between the slide and the child, making each of his like-charged hairs repel each other.

Which statement accurately describes renewable energy sources?
They take millions of years to form and should be used responsibly.
They include fossil fuels and hydroelectric power.
They are found in nearly limitless supply.
They provide the majority of the energy for the United States.
Answer:
They are found in nearly limitless supply.
Explanation:
Renewable energies (or renewables) are ways to generate energy from (theoretically) unlimited natural resources. These resources are either available with no time limit or replenish more quickly than the rate at which they are consumed. Renewable energies are generally spoken of as opposed to fossil fuel energies.

(Gillian is investigating the distribution of charge in objects using friction. Gillian gently rubs a rubber balloon on the fur of her pet cat. When she pulls the balloon away from the cat's fur, the fur is attracted to the balloon.) Which BEST explains why the fur becomes attracted to the balloon?
A) Rubbing the balloon along the cat transfers extra protons from the balloon to the cat.
B) Rubbing the balloon along the cat transfers extra electrons from the cat to the balloon.
C) Rubbing the balloon along the cat creates extra protons that will stick to both the balloon and cat.
D) Rubbing the balloon along the cat creates extra electrons that will stick to both the balloon and cat.
Rubbing the balloon along the cat transfers extra electrons from the cat to the balloon.
What are static charges?
The static charges are the charges that are developed on objects that are stationary. There are several ways by which static charges could be developed. One of the ways that static charges could be developed is by the use of friction. Friction is known to occur when surfaces are being rubbed together in such a way that there must have to be a transfer of charges.
Thus, in this case, we are told that Gillian gently rubs a rubber balloon on the fur of her pet cat. When she pulls the balloon away from the cat's fur, the fur is attracted to the balloon.
The reason why the fur becomes attracted to the balloon is that rubbing the balloon along the cat transfers extra electrons from the cat to the balloon.

According to the forces of attraction, rubbing the balloon along the cat transfers extra electrons from the cat to the balloon.
What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

Which type of data would be considered qualitative data? diameter measured distance travelled density calculated discoloration amount
Answer:
Explanation:
Qualitative data is descriptive information that cannot be measured in numbers. So among the choices, only discoloration amount is descriptive and cannot be measured.
The type of data which will be considered as qualitative data is discoloration amount.
What is qualitative data?Qualitative data is that data which depends on the quality not in the quantity of any object.
Diameter, travelled distance and density are the quantitative data means they all depends on the quantity and measurement. Whereas the discoloration amount is the qualitative data as it is not measurable and not depends on the quantity.
Hence correct answer is discoloration amount.
