Answer:
As each mower presumably needs the same torque to start, and torque is a product of force and moment arm, the longer moment arm of 10.42 cm on Uwi's mower means lower force is required when compared to Urippe's shorter moment arm of 1.35 cm
350 rev/min = 350(2π) / 60 = 36.652 rad/s
36.652 rad/s / 0.294 s = 124.66... <u>125 rad/s²</u>
a = αR = 125(0.1042) = 12.990... <u>13 m/s²</u>
a = αR = 125(0.0135) = 1.68299... <u>1.7 m/s²</u>
I am GUESSING that we are supposed to model these mowers as a uniform disk
τ = Iα
FR = (½mr²)α
F = mr²α/2R
Urippe's pull = (3.56)(0.2041²)(124.66) / (2(0.0135)) = 702.008... <u>702 N</u>
Usi's pull = (3.56)(0.2041²)(124.66) / (2(0.1042)) = 90.9511...<u>91.0 N</u>
L = Iω = (½(3.56)(0.2041²))36.652 = 2.71771...<u>2.72 kg•m²/s down</u>
using the right hand rule
The answer would be true.
Explanation:
Although some silk in is more flexible than others, there are many varieties. There are high medium and low flexibility. Even though there are different levels, it is still considered a trait. Again, the answer in True.
Hope this helped you. I did some research on this before, so this should be correct. If you aren’t satisfied then you can ask me a question! Have a nice day.
:)
Answer:
yes. why do you need this answered asap? lol
The answer is going to be C, Bacteria. Therefore the organisms that are used to manufacture human insulin would be bacteria.
It uses the corkscrew to anchor it to the cork and a lever to pull the cork out
Hope this helps buddy:D
