Svetradugi [14.3K]
Below are the questions:

A) A hovering mosquito is hit by a raindrop that is 45 times as massive and falling at 8.9m/s , a typical raindrop speed. How fast is the raindrop, with the attached mosquito, falling immediately afterward if the collision is perfectly inelastic? 

<span>B) Because a raindrop is "soft" and deformable, the collision duration is a relatively long 8.0 ms. What is the mosquito's average acceleration, in g's, during the collision? The peak acceleration is roughly twice the value you found, but the mosquito's rigid exoskeleton allows it to survive accelerations of this magnitude. In contrast, humans cannot survive an acceleration of more than about 10 g. 
</span>
Below are the answers:

a. <span>MU = (M + m)V; where M = 45 m, U = 8.9 m/s, find V = ?. V = (45/46)*8.9 = 8.7 m/s 
</span>
b. <span>F = m dV/dT = m 8.7/8E-3 = m 1.0875E+03; so G = 1.0875E+03/9.8 = 111 G's.</span>

The level of ATP tells the level of vitality inside heart cells, telling how well the heart capacities. The sorts of cells in the body that I would hope to require the most ATP are muscle cells. Muscle cells require bigger measures of ATP. They are in charge of the greater part of our developments. The majority of the vitality consumed amid your day is through development of your body by skeletal muscles.

50 POINTS!!!! Heart disease is the leading cause of death among both men and women in the United States. It is usually caused wh
Paul [167]

Answer:

Heart disease is prevalent in the United States because... well, we consume a lot of sodium and fat. If you look at the stats, we are the third country with the most obese residents, with a whopping percentage of 36.20% people in the US tipping the scales. Also, people smoke a lot. Not just adults, but teenagers. Because of this, youngsters tend to also get heart disease too, despite the small age. According to cdc.gov, a family history of heart disease increases the rates, especially if one of your relatives got it under the age of 50. Due to the smoking rates at a young age, those diseases tend to transfer and increase the rates of the future US citizens.

Heart disease can affect a lot of organs, but listing them would be a pain. Here are the highlights: The heart and the lungs are intimately connected. This means that having heart disease may lead to having trouble breathing. You may have chest pains, and particularly in woman, it may affect the digestive system and cause stomach pain when eating.

Which lipoprotein carries cholesterol to the cells in your body, but can get stuck in arteries while traveling in the blood, dep
Viktor [21]

LDL (low-density lipoprotein) carry cholesterol from the liver to the tissues and can contribute to the formation of plaque that builds up in the arteries.

<h3>What are lipids?</h3>

Lipids are soluble in fat and to circulate in the blood, which is an aqueous medium, they form lipoprotein complexes called lipoproteins, these constitute a transport medium and circulating reservoir for lipids.

<h3>Characteristics of LDL (low-density lipoprotein)</h3>

  • Low-density lipoproteins, composed of 50% triglycerides, are the ones that transport the lipids synthesized in the liver to other parts of the body.

  • LDL, composed mainly of cholesterol, when in excess, also deposits it on the walls of the arteries, contributing to the formation of plaque.

Therefore, we can conclude that excess LDL (low-density lipoprotein) poses a health risk because it facilitates the accumulation of fat in the arteries.
