Answer:
An observer in space will see that Earth requires 23 hours, 56 minutes, and 4 seconds to make one complete rotation on its axis. But because Earth moves around the Sun at the same time that it is rotating, the planet must turn just a little bit more to reach the same place relative to the Sun.
Answer:
Yes, but actually no.
Explanation:
Since gravity pulls inward from all directions equally, a clump, if big enough, will eventually become a round planet. Inertia then keeps that planet spinning on its axis unless something occurs to disturb it.
To simplify, due to gravity, things will keep spinning until something stops it from spinning (this applies to being in space, I think).

In what year should we expect ocean pH to adversely affect zooplankton population?
The year we should expect ocean pH to adversely affect zooplankton population is 2030.
What are zooplanktons?Zooplankton is a small floating or weakly swimming organisms that drift with water currents and, with phytoplankton, make up the planktonic food supply upon which almost all oceanic organisms are ultimately dependent.
Ocean acidification may affect zooplankton directly by decreasing in pH, as well as indirectly by trophic pathways, where changes in carbon availability or pH effects on primary producers may cascade up the food web thereby altering ecosystem functioning and community composition.

Which of the following is an example of refuse? A. Medical waste thrown out by a hospital B. The waste produced by a chemical factory C. The waste people flush down their toilets B. Spoiled food thrown out by a supermarket
Answer:
the last one
Explanation:
The best example of refuse here is option D. Spoiled food thrown out by a supermarket.
What is refuse?Refuse refers to any disposable materials, which includes both recyclable and non-recyclable materials. The term refuse is often used interchangeably with waste, but refuse is a broader term that applies to anything that is leftover or refused as a result of mishandling or spoilage occurred during manufacturing or processing.
Whereas, waste refers to leftovers including manufacturing byproducts as chemicals, or dirty water that cannot be reused. Municipal solid waste (MSW), sometimes known as refuse, is a community's nonhazardous solid waste that needs to be collected and transported to a processing or disposal location.
Thus, from description, best example of refuse here is option D. Spoiled food thrown out by a supermarket

Are the nitrogenous bases just free floating in the nucleus? If so..why are they just floating? And how are they made? Thank you :)
Answer:
No, they order in sequences of base pairs in DNA
Explanation:
As you know, there are four nucleotides: Adenine, Thiamine, Cytosine, and Guanine. Adenine and guanine are purines, and cytosine and guanine are pyrimidines. You might not know what that means, so just in case purines are longer and pyrimidines are shorter. Therefore, A pairs with T and C with G. These pairings, along with other structural enzymes, build strands of DNA in the nucleus. I hope that helped, if you have more questions just let me know.

HELP! A 20-kg bag of rice dropped from an airplane. What is the gravitational force on the bag? Acceleration due to gravity is 9.8 m/s/s.)
10.02 N
19.6 N
20.8 N
196 N
Answer:
20.8
Explanation:
I took it and it was right
196N is the gravitational force on the bag. So, the correct option is D.
What is gravitational force?Any two items in the universe can be attracted to one another by the gravitational force. All mass-containing objects are drawn towards one another by this attraction, which also keeps the moon in its orbit around the Earth and the planets in their orbits around the sun.
The mass of the two objects and their separation determine the gravitational force's strength. The force of gravity between two objects is directly proportional to their masses and inversely correlated to the square of their distance, according to Newton's law of universal gravitation.
The gravitational force on the bag can be calculated using the formula:
force = mass x acceleration due to gravity
Plugging in the given values, we get:
Force = 20 kg x 9.8 m/s/s
Force = 196 N
Therefore, the correct option is D.

6. If you are given a piece of white marble and a piece of white quartzite what test can
you do to determine which is which? What results will you get?
Answer:
Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. Such conditions fuse the quartz grains together forming a dense, hard, equigranular rock. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content. Quartzite generally comprises greater than 90% percent quartz, and some examples, containing up to 99% quartz, and are the largest and purest concentrations of silica in the Earth's crust. Although a quartz-rich sandstone can look similar to quartzite, a fresh broken surface of quartzite will show breakage across quartz grains, whereas the sandstone will break around quartz grains. Quartzite also tends to have a sugary appearance and glassy lustre. The variety of colours displayed by quartzite are a consequence of minor amounts of impurities being incorporated with the quartz during metamorphism. Although quartzite can sometimes appear superficially similar to marble, a piece of quartzite will not be able to be scratched by a metal blade, and quartzite will not fizz on contact with dilute hydrochloric acid.Explanation:
