Answer:
10/7 m/s² or 1.43 m/s²
Explanation:
Force=Mass*Acceleration
F=ma
Applied Force=4,000N
Mass of the truck=2,800Kg
Acceleration=?
4000N=2800*a
4000/2800=a
10/7 m/s²=a
1.43 m/s²=a (approx)

What is meant by involuntary muscle?
Muscles that contract or move voluntarily are known as involuntary muscles. Involuntary muscle action is controlled by the autonomic nervous system. The internal organs or viscera that exhibit consistent, gradual contractions and involuntary motions are typically connected with these muscles. The heart is one such uncontrollable muscle.The autonomic nervous system, hormones, and local variables can cause the involuntary activity of the majority of involuntary muscles by neural stimulation. But in other muscles, such as the walls of visceral organs, extending the muscle can cause an involuntary muscle contraction.
Therefore, option (C) is correct.

(1 Point)
A. sac that stores water, nutrients and waste products
B. sac filled with digestive chemicals
C. jelly-like substance within the plasma membrane
D. stack of membranes that package materials
The vacuoles are the structures found inside the cells that store water, nutrients as well as waste products. So the correct option is option A.
The vacuole plays a vital role in many cells. Mature cells of all land plants, most fungi, and algae (with the exception of prokaryotes) contain vacuoles. On the other hand, animal cells and immature plant cells (as well as some highly immature plant cells (stone cells) contain no vacuoles.
These vacuoles store the essential nutrients and water that a cell needs to survive. They also contain the waste of the cell and protect it from contamination.

Write a list of the words that directly intervene in the water cycle, that is, that are part of the different states that present the water cycle.
Answer:
Evaporation, transpiration, condensation, precipitation, and runoff.
Explanation:
Evaporation, transpiration, condensation, precipitation, and runoff are the words that directly intervene in the water cycle. The evaporation occurs in the water bodies when the water is heated with the help of solar radiation whereas transpiration occurs from the plant body. When this water vapors goes in the atmosphere, they form clouds by condensation of water molecules and as a result precipitation occurs. Some rain water is absorbed by the soil while the remaining run-off on the surface in the form of streams, lakes and rivers etc.

The organism that is most likely to be found in a deep sea trench is Archaebacteria. The correct option is a.
What is Archaebacteria?The domain of single-celled organisms is called Archaea. These microbes are prokaryotes because they lack cell nuclei.
The term "archaebacteria," which was used to describe archaea when they were first categorized as bacteria, is no longer in common usage.
The group of microorganisms known as archaebacteria is frequently referred to as a kingdom. They are thought to be an ancient form of life that originated independently from bacteria and blue-green algae.
Archaea are well known for their preference for living in harsh conditions.
There is likely life there, and that life is likely an archaeal species whether it is extremely hot (hotter than 100° Celsius), freezing, acidic, alkaline, salty, deep in the ocean, or even assaulted by gamma or UV radiation.
Thus, the correct option is a.
