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.
Answer:
Force = 485000 Newton.
Explanation:
Given the following data;
Mass = 485000 kg
Initial velocity = 20m/s
Final velocity = 25m/s
Time, t = 5 seconds
To find the force;
First of all, we would calculate the acceleration of the train i.e the rate of change of the velocity of the train with respect to time.
Mathematically, acceleration is given by the equation;
Where;
a is acceleration measured in
v and u is final and initial velocity respectively, measured in
t is time measured in seconds.
Substituting into the equation, we have;
Acceleration = (25 - 20)/5
Acceleration = 5/5
Acceleration = 1m/s²
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Force = mass * acceleration
Force = 485000 * 1
Force = 485000 Newton.
