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:
534.7
Explanation:
55/1010 = 0.0545m^3
1000(0.0545)(9.81) = 534.7 N (kept at 4 sig figs)
Explanation:
(a) Net force acting on the block is as follows.
or, ma = -mg Sin (\theta)[/tex]
a =
=
= -3.35
According to the kinematic equation of motion,
Distance traveled by the block before stopping is as follows.
s =
=
= 21.5 m
According to the kinematic equation of motion,
v =
0 =
= 7.16 sec
Therefore, before coming to rest the surface of the plane will slide the box till 7.16 sec.
(b) When the block is moving down the inline then net force acting on the block is as follows.
ma =
a =
=
= 3.35
Kinematics equation of the motion is as follows.
s =
21.5 m =
=
= 3.58 sec
Hence, total time taken by the block to return to its starting position is as follows.
t =
= 7.16 sec + 3.58 sec
= 10.7 sec
Thus, we can conclude that 10.7 sec time it take to return to its starting position.
To find black holes in space, scientists use telescopes to study visible light, X-rays, and radio waves. When gas orbits a black hole, it gets very hot and starts emitting X-rays and radio waves. Through special telescopes, the area surrounding the black hole looks really bright.
Answer:
625 N
Explanation:
The impulse given to the nail is equal to the change in momentum of the hammer:
where
F is the force exerted by the hammer
is the time of contact
is the mass
is the change in velocity of the hammer
Substituting the data and re-arranging the equation, we can find the force:
