Answer:
Kidney
Explanation:
One of the main function of the kidney is to maintain the homeostasis of sodium and potassium ions in the blood and body.
Aldosterone is a key steroid hormone that balances sodium and potassium ions in the blood and body fluid. Potassium and sodium ions generate electric impulse in the body which helps to perform different activities such as muscles flexing.
Kidney function for reabsorption and secretion, in which reabsorption of Na is done nd balances the sodium and potassium in the blood and body.
Answer:
The work done by the man is 260 J.
(E) is correct option.
Explanation:
Given that,
Force = 80 N
Distance = 5.0 m
Angle = 30°
Acceleration = 1.5 m/s²
Let F be the man's force
We need to calculate the force
Using balance equation




We need to calculate the work done by the man
Using formula of work done



Hence, The work done by the man is 260 J.

Answer:
is the minimum depth of snow for survivable stopping.
Explanation:
Given:
- terminal velocity of fall,

- mass of the paratrooper,

- force on the paratrooper by the ice to stop him,

<u>Firstly, we calculate the deceleration caused in the snow:</u>



Now, using equation of motion:
....................(1)
where:
v = final velocity of the body after stopping
u = initial velocity of the body just before hitting the snow
a = acceleration of the body in the snow
s = distance through in the snow
Putting respective values in eq. (1)
