<h2>Sugary Sports drink for hydration.</h2>
Explanation:
- Sugary sports drinks are the best for hydration. False.
Sugary sports drink are not the best option for hydration because many times they lead to excess calorie intake and pave the way for obesity if the physical exercise is not enough to burn the entire calorie. Sugary drinks also have ill effects on tooth due their low pH levels.
The best option for hydration is always water.
Answer:
Velocity of the fish relative to the water when it hits the water = 14.32 m/s along 77.91° below horizontal.
Explanation:
Vertical motion of fish:
Initial speed, u = 0
Acceleration, a = 9.81 m/s²
Displacement, s = 10 m
We have equation of motion, v² = u² + 2as
Substituting
v² = 0² + 2 x 9.81 x 10 = 196.2
v = 14 m/s
Final vertical speed = 14 m/s
Final horizontal speed = initial horizontal speed = 3 m/s
Final velocity = 3 i - 14 j m/s
Magnitude
Direction
Velocity of the fish relative to the water when it hits the water = 14.32 m/s along 77.91° below horizontal.
Answer:
a. ≈ 1.22449s
b. ≈ 14.69387m
c. ≈ 0.532415s
Explanation:
Because we are trying to find when it is at it's highest point we can safely say that it's velocity at that point is 0m/s,
therefore we can use the equation:
and do some algebra to get:
Now we plug in our values (note that this is assumed to be on Earth and that because it says that upwards is positive, we set g to be negative to say that it is pointing down):
To find the final height we can use:
and plug in our values to get:
To find the time we can use the time dependent position equation:
This here can be made into a quadratic equation like so (xi is set up to be 0m, so the equation wont have it):
Here we can use the quadratic formula:
And now it would be best if we put in our values (xf = 5m because that is our question):
Finally we have simplified enough to be worth solving for:
We get:
and
Because time is always positive we want to choose the plus answer.
Answer:
Triton orbits Neptune in what is known as a retrograde orbit. This means that it orbits Neptune a direction opposite the planet's rotation. ... Others think that Triton may have been formed elsewhere and then captured by Neptune's gravity.

Answer:
(B) a whole number of wavelengths.
Explanation:
Two beams of coherent light start out at the same point in phase and travel different paths to arrive at point P. If the maximum destructive interference is to occur at point P, the two beams must travel paths that differ by a whole number of wavelengths.
When the resultant effect of the combination of two identical waves result in their annihilation or complete cancellation of the effect of each other, destructive interference takes place. Hence to have two wave sources producing waves that have the same frequency wavelength and amplitude and which are always in phase with each other or have a constant phase difference are said to be Coherent source
