Answer:
n = 223 revolutions
Explanation:
It is given that,
The angular acceleration of a helicopter blade,
Initial speed of the helicopter blade,
The final speed of the blade,
We need to find the number of revolutions. Firstly we will find the angle turned by the blade. Let the angle is . So,
Let there are n number of revolutions made by the blade. So,
or
n = 223 rev
So, there are 223 revolutions.
Answer:
a) 12.56 rad per minute
b)62.8 inches per minute
Explanation:
Given:
- Radius of the blades, R=5 inches
- Frequency of the blades, f=2 revolutions per minute
a)
Let be the angular velocity of the blade which is given by
b)
Let v be the linear speed of the tip of the blade which is given by
Hence we have calculated the angular velocity and linear speed.
Answer:
ADH
Explanation:
The osmotic pressure depends on the osmolality of the plasma. In addition, the plasma osmolality is measured by the plasma content of the total body. And when there is a drop in total body volume then the plasma osmolality will boost as the plasma concentration of Na+ will rise.
As a response, water will transfer the concentration gradient downward from all cells to plasma. It causes contraction of the osmoreceptors cells. As a consequence, afferent impulses are sent to the posterior pituitary gland from the hypothalamus, to enhance the production of ADH.
