What is the acceleration of an object if it goes from a velocity of +25 m/s to rest in 5.0 s?A. –5 m/s^2


B. +5 m/s^2


C. –25 m/s^2


D. +25 m/s^2

Answers

Answer 1
Answer: In this question, there are several information's that can be used to determine the right answer.Let us first check all the information's that have been provided in the question.
Initial velocity = 25 m/s
Final velocity = 0 m/s
Initial time = 0 second
Final time = 5 second
Now we can write an equation to determine the acceleration.
Acceleration of the object = (Final velocity - Initial velocity)/ (Final time - Initial time)
                                         = (0 - 25)/ (5 - 0)
                                         = - 25/5
                                         = -5 m/s^2
So we find the acceleration of the object as -5m/s^2. the correct option among the given options in the question is option "A".
Answer 2
Answer:

the correct answer is -5 m/s^2

hope this helps:)

Three examples of bacteria billions of years ago

Answers

three examples of bacteria billions of years ago are the coccus, bacillus, and spirochete

Final answer:

Bacteria billions of years ago played a critical role in shaping the Earth's atmosphere and the development of life. Cyanobacteria, archaea, and stromatolites are examples of bacteria from that time.

Explanation:

Billions of years ago, bacteria played a crucial role in shaping the Earth's atmosphere and the development of life. Some examples of bacteria that existed back then include:

  1. Cyanobacteria: These ancient bacteria were the first organisms capable of photosynthesis, releasing oxygen as a byproduct and contributing to the oxygenation of our planet's atmosphere.
  2. Archea: Certain types of archaea bacteria, such as methanogens, were present and played a role in the early carbon cycle, producing methane gas.
  3. Stromatolites: These are fossilized bacterial mats found in ancient rocks, providing evidence of early bacterial life and their important role in Earth's history.

How do the chromosomes at the end of meiosis 1 compare with the chromosomes at the end of meiosis 2

Answers

Chromosomes have two chromatids at the end of meiosis I and one chromatid at the end of meiosis II. The correct option is D.

What is meiosis?

The division of gametic or sex cells is known as meiosis. The process of reproduction involves this. It takes eight phases to finish. It is split into two sections. The first and second meiosis.

When a cell is dividing, it is a haploid cell. One set of chromosomes makes up a haploid cell. It includes all of its chromosomes during meiosis. Chromosomes are hereditary material.

In the chromosomes in meiosis 1 a full set of chromosomes is present and in meiosis 2, the number is diploid (2N).

Therefore, the correct option is D,Chromosomes have two chromatids at the end of meiosis I and one chromatid at the end of meiosis II.
