use newton's first law of motion to explain why you feel tossed around whenever a roller coaster goes over a hill or through a loop

Answers

Explanation:


A roller coaster is hard to stop because it has a lot of inertia. Inertia can be simplified to, "objects want to keep doing what they are doing." It's when they are forced to do something different that they are doing that is why roller coaster riders experience the float or tossing around of the ride.
Newton's First law of motion:  An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.
This is also known as the law of inertia
Anyways,  you feel tossed around because unbalanced forces are acting upon you while riding on a roller coaster.  Hope this helps!

mitosis produces four daughter cells in meiosis produces two diploid cells ​

Answers

Answer:

Mitosis produces two daughter cells and meiosis produces four daughter cells

Explanation:

In mitosis, you start off with one parent cell, and it duplicates itself, so as you could see, you would have the original cell as well as the duplicated version, which is a total of 2. In meiosis, there are two main phases, Meiosis I and Meiosis II. The first phase produces two cells and the second phase takes those two cells to form four daughter cells / gametes
