Answer:

Competence

Explanation:

In hydrology, stream competence is a measure of the largest particle a stream can carry. Flow velocity and volume of flow change the stream competence.

An associated concept is stream capacity, but capacity measures the quantity of sediment and not the size of sediment particles.

You have developed a method in which a paint shaker is used to measure the coefficient of static friction between various object

Paladinen [302]

Answer:

0.62

Explanation:

A = Amplitude

f = Frequency = 1.85 Hz

$\mu$ = Coefficient of static

g = Acceleration due to gravity = 9.81 m/s²

Angular frequency

$\omega=2\pi f\\\Rightarrow \omega=2\pi\times 1.85$

Maximum acceleration

$a_{max}=A\omega^2\\\Rightarrow a_{max}=0.045\times (2\pi\times 1.85)^2$

$a_{max}=\mu g\\\Rightarrow \mu=\frac{a_{max}}{g}\\\Rightarrow \mu=\frac{0.045\times (2\pi\times 1.85)^2}{9.81}\\\Rightarrow \mu=0.62$

How do professional bicycle riders reduce friction. Name two ways. Thx

wlad13 [49]

A well maintained bicycle is key. Oil the chain so that it's less likely to get hung up. It will have a smoother flow. Another could be in their clothing. Notice they usually wear good fitting clothing? I believe the more from fitting pants help clothing friction. Another way could be keeping the tires well inflated so that the tires aren't dragging. Rolling along smoothly on properly inflated tires seems like a must. Get a few more answers along with mine, so that you have a variety to choose from.
