The correct answer is: <span>The water and ions lost through perspiration must be replaced during recovery so the body can replenish fluid and stored energy
This is the relation of perspiration to recovery after exercise. That is why it is important to replenish the body with water to avoid dehydration. </span>
Answer:
(A) 1.01 s
(B)
Explanation:
horizontal distance (L) = 3 m
vertical height (h) = 1.25 m
acceleration due to gravity (g) = 9.8 m/s^{2}
(A) hang time refers to how long the person remains in the air, and is the summation of the time it took attain maximum height and the time it takes to get back to the ground.
- it is going to take the same amount of time to attain maximum height and to return to the ground.
- from s = ut + 0.5g we can get the time taken to attain maximum height.
where s = vertical distance = 1.25 m
u = initial velocity = 0 (since body starts from rest)
g = acceleration due to gravity = 9.8 m/s^{2}
t == time taken to get to maximum height
the equation now becomes s = 0.5g
1.25 = 0.5 x 9.8 x
= 1.25/(0.5x9.8)
t =
t = 0.505 s
- now that we have the time taken to attain maximum height which is also equal to the time it takes to get back to the ground.
total time = time taken to attain maximum height + time it takes to get back to the ground.
total time = 0.505 + 0.505 = 1.01 s
(B) when horizontal distance = 6 m , the hang time would remain the same, because the horizontal component does not affect the vertical component . Also we can see that from the equation used in part A above the horizontal component was not used to solve for the time. Therefore hang time = 1.01 s
Answer:
The potential energy of the electron in the field of the positive proton point charge is U(r) = -qeV(r) = - keqe2/r. The total energy is the sum of the electron's kinetic energy and its potential energy.
Explanation:
In each case the origin is located at the intersection of the axes. The electric potential from a single charge is defined to be zero an infinite distance from the charge, and the electric potential associated with two charges is also defined to be zero when the charges are infinitely far apart.
<span>sometimes you can see yourself as well, due to refraction and reflection
</span>
That is called the "Revolution Period of a planet" and one year on Jupiter equals to 4300 days as compared to Earth
In short, Your Answer would be 4300
Hope this helps!
