Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=
r

................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v

Answer:
Purpose of ecosystems
Explanation:
Which of these are causes of long-term climate change? Check all that apply.
Answer:
Where are the answers?
Explanation:
Answer: Earths orbit around the sun, solar energy, and volcanic eruptions
Explanation:
Earths orbit: At other times, the ellipse is more pronounced, so that the Earth moves closer and further away from the Sun in its orbit. When the Earth is closer to the Sun, our climate is warmer and this cycle also affects the length of the seasons.
Solar energy: Solar produces less life-cycle GHG emissions than conventional fossil fuel energy sources.
Volcanic eruptions: Volcanic eruptions of this magnitude can impact global climate, reducing the amount of solar radiation reaching the Earth's surface, lowering temperatures in the troposphere, and changing atmospheric circulation patterns.
Imagine a molecule of free glucose in the blood after a large meal. Which of the following statement is/are true?
a. Be converted to fructose-2,6-bisphosphate in a liver cell
b. Become a glycerol backbone in a triglyceride in an adipose cell
c. Become part of a fatty acid chain in a triglyceride in an adipose cell
d. Be polymerized into glycogen in a skeletal muscle cell
e. Be phosphorylated and bind allosterically to glycogen synthase
Answer:
e. Be phosphorylated and bind allosterically to glycogen synthase
Explanation:
The initial step in the pathways that utilize glucose is its phosphorylation in C6. Glucose-6-phosphosate
The statement that is true is phosphorylated and binds allosterically to glycogen synthase. The correct option is e.
What is phosphorylation?Phosphorylation is a biological process in which a phosphate group is added to an organic molecule. Phosphorylation processes include the following:
1) phosphate added to glucose to generate glucose monophosphate
2) Phosphate addition to adenosine diphosphate (ADP) to generate adenosine triphosphate (ATP).
Phosphorylation regulates several biological functions, including cell cycle, proliferation, death, and signal transduction pathways.
ADP-phosphate group of a reactive intermediate with the transfer of a chemical reaction in which ATP is created in substrate level phosphorylation.
Therefore, the correct option is e. Be phosphorylated and bind allosterically to glycogen synthase.

Answer:
Animalia.
Explanation:
Just ask!
Hope this helps. :)
Animalia that consist of many cells with an organized nucleus, have two parents, and eat food.
What are the characteristics of Animalia?Animal cells are the basic living unit of organisms in the kingdom Animalia. They are eukaryotic cells, which means they have a true nucleus and special structures called organelles that perform various tasks.
All members of the Animalia are multicellular, and all are heterotrophs (meaning that their nutrition depends directly on or indirectly on other organisms). Most swallow food and digest it in an internal cavity. Animal cells lack the rigid cell walls characteristic of plant cells.
Classification of Fauna - Porifera, Coelenterata, Platyhelminthes, Aschelminthes, Annelida, Arthropoda, Mollusca, Echinodermata, Chordata.

Which best describes chromosomal dilatation
Answer:Changes that affect the structure of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can affect many genes along the chromosome and disrupt the proteins made from those genes.
Structural changes can occur during the formation of egg or sperm cells, in early fetal development, or in any cell after birth. Pieces of DNA can be rearranged within one chromosome or transferred between two or more chromosomes. The effects of structural changes depend on their size and location, whether gene function is interrupted, and whether any genetic material is gained or lost. Some changes cause health problems, while others may have no effect on a person's health.

A. interspecific
B. intraspecific
C. invasive
Answer: intraspecific competition
hopes this helps.
Answer:
A. Interspecific is my best guess.
Explanation:
“Inter” means inside, so I’m guessing it would relate to the organisms being of the same species. “Intra” means outside. And invasive just doesn’t make any sense.

What effect does increase salinity have on the density of water?
1. No affect unless temperature also changes
2. Decreases density
3. Increases density
Answer:
3
Explanation:
For example,The density of seawater depends on the content of salt. It is known that the density of salt is 2.165g/cm3, so the more salt, the greater the density of mixed liquid.
Answer:If you know that dissolution of salt only marginally affects the volume of the solution, how would you expect the density to evolve? It should reasonably increase.
Explanation:
at a given temperature, Should salts be dissolved in the water, and the volume remains reasonably constant, the density
. A solute binds water molecules around itself in a coordination sphere, and should a salt be dissolved, both anion and cation must be solvated; hence an increase in solution density with respect to water.
