<span>Science is always defined as the body of knowledge and linked to something
related to the physical world, phenomena and lives of everything that exist on
Earth. Science is categorized in various ways. Pure, practical or theoretical, is the largest
distinction of science or whether
science is applied. Generally, pure
science is subdivided into Physical sciences, Earth sciences, and Life
sciences. Physical sciences deal with
energy and matter, Earth sciences explain Earth’s phenomena, to the solar
system where it belongs and its atmosphere. And finally, life sciences describe
internal processes of living organisms, its relationship to each other and to
its environment.</span>
Answer: velocity = -0.65 speed =0.65
Explanation:
Velocity =speed+direction speed =distance/time
The solution for this problem is:
If they feel 50% of their weight that means that the
centripetal force is also 50% of their weight 1g - 0.5g = 0.5g
Then 0.5* 9.8m/s² * 18m = 88.2 would be v²
Then get the square root, the answer would be:
and v = 9.391 m/s is the answer.
With the blocking of activation of clotting factors, the rate of conversion of fibrinogen to fibrin will decrease to a huge extent and this will prevent the clot formation.
Option A
<h3><u>Explanation:</u></h3>
The process of stopping of flow of blood through any wound by formation of a clot is known as blood clotting. The clot in blood is formed by conversion of the fibrinogen protein into its polymer form fibrin which forms a meshwork.
The conversion of fibrinogen to fibrin requires a lot of enzymes and factors present which is required one by one, known as the Cascade theory. Total of 13 factors are required, where there are prothrombin, thromboplastin, and different other factors. Inactivation of any of the 13 factors will lead to less conversion of fibrinogen to fibrin, thereby the rate of conversion will highly decrease.
