Answer:
27.82m
Explanation:
The distance of the cyclist can be calculated using the formula:
S = ut + 1/2 (at^2)
Where; S = distance
u = initial velocity
a = acceleration
t = time
However, to find acceleration, we use:
a = v - u/t, where v is the final velocity
According to this question, u = 4.2m/s, v = 6.3m/s, t = 5.3s
a = 6.3 - 4.2 / 5.3
a = 2.1/5.3
a = 0.396m/s^2
Hence, using S = ut + 1/2 (at^2)
S = (4.2 × 5.3) + 1/2 (0.396 × 5.3 × 5.3)
S = 22.26 + 5.56
S = 27.82
Therefore, the cyclist travel in 27.82m
Remains unchanged (as it's a solid)
Frequency measures how many waves pass a certain point in a given amount of time.
High frequency means the waves are closer together and more frequent, making for a lower wave length.
Low frequency means the waves are farther apart and less frequent, making for a higher wave length.
So the answer is frequency.
Answer:
give me more information so I can help
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!
