Answer:
The vibrating length of the air column is greater than the actual length of the organ pipe
Explanation:
Centripetal force is mass times centripetal acceleration:
F = m v² / r
If force is doubled while mass and radius are held constant, then velocity will increase.
2F = m u² / r
2 m v² / r = m u² / r
2 v² = u²
u = v√2
So the velocity increases by a factor of √2.
Tycho Brahe ( 1546 - 1601 ) was a Danish astronomer known for his accurate astronomical and planetary observations. Tycho tried to produce a model with the best of both Ptolemy ( earth-centered solar system ) and Copernicus ( sun-centered solar system ).
Answer: B ) observation.
Answer:
To a tenth of a mililiter (0.1mL)
Explanation:
When considering the precision of a measurement system, a more precise intrument needs to record smaller intervals of data; a better resolution. In this case we have a cylinder with a resolution of 1 mL. When we pour the amount of water we can't precisely measure anything less than 1 mL UNLESS it is added to the pipet described in this problem which records measurements of up to 0.1 mL (a tenth of a mililiter). Thus the total measurement system can only report a resolution of up to 0.1 mL
The woman is correct because it is the pace he is moving not walking.
