Wave speed = frequency * wavelength
Rearrange so it's equal to wavelength. Do this by diving both sides by frequency to leave you with:
Wave speed / frequency = wavelength
340 / 265 = 1.2830 m
Answer:
The initial velocity of the gymnast is 8.5 m/s.
Explanation:
We can use the kinematic equation
to figure out the initial velocity 
of the gymnast.
Now, when the gymnast reaches the maximum height, the distance he has traveled is 
, and his velocity is zero; therefore 
.
Thus, we have
Answer:
The answer is D.
Explanation:
This is because mass always remains constant and weight is dependent on a gravitational pull.
Answer:
I'm no expert, but multitasking is a no bueno. Because multitasking reduces your efficiency and performance because your brain can only focus on one thing at a time. When you try to do two things at once, your brain lacks the capacity to perform both tasks successfully.
Therefore I would choose A, considering he could easily workout another time, whilst the test is a one time thing. He can't redo the test, but he can workout again. So my answer is A.
If he HAS to workout and study at the same time, then C would be appropriate.
I hope this helps!
