Question : What is the no-friction needed speed (in m/s ) for these turns?
answer:
20.1 m/s
Explanation:
2.5 mile track
number of turns = 4
length of each turn = 0.25 mile
banked at 9 12'
<u>Determine the no-friction needed speed </u>
First step : calculate the value of R
2πR / 4 = πR / 2
note : πR / 2 = 0.25 mile
∴ R = ( 0.25 * 2 ) / π
= 0.159 mile ≈ 256 m
Finally no-friction needed speed
tan θ = v^2 / gR
∴ v^2 = gR * tan θ
v = √9.81 * 256 * tan(9.2°) = 20.1 m/s
<h2>Answer:</h2>
Phytochemicals are compounds that are produced by plants ("phyto" means "plant"). They are found in fruits, vegetables, grains, beans, and other plants. Some of these phytochemicals are believed to protect cells from damage that could lead to cancer.

The <em>approximate</em> difference in pressure between the two balls is 1961.4 pascals.
<h2>Procedure - Pressure difference between two balls at distinct heights and submerged in the same fluid</h2>
<h3>Mathematical model for difference in pressure</h3>
The difference in pressure between the two balls is expressed by a formula derived from the concept of manometric pressure (), in pascals:
(1)
Where:
- - Height difference between balls 2 and 3, in meters.
- - Water density, in kilograms per cubic meter.
- - Gravitational acceleration, in meters per square second.
<h3>Calculation of the difference in pressure</h3>
If we know that , and , then the difference in pressure is:
The <em>approximate</em> difference in pressure between the two balls is 1961.4 pascals.
