Answer: Your question is missing below is the question
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
There is 0 acceleration because the pony is moving at a constant velocity
Unalienable rights are the natural rights to which all people are entitled.
The right of the people to alter or to abolish government means that the government exists to serve the people.
The words "governments are instituted among men" describe the idea of a social contract.
Answer: 1 and 6, 2 and 5, 3 and 4.
<u>Explanation:</u>
The government is a system in which the power to administer or to govern the country is given to that system and divided among the different organisations of that system. There is proper division of the power so that there is no abuse of the power by the government officials.
The government of the country is for the betterment of the country and for the welfare of the people of that country. They exist for the people and therefore the people have to right to change or abolish the people. There are certain unalienable rights given to the citizens which can not be taken from them.
Answer:
Temperature when sound wave with wavelength 0.47m has frequency 741 hz is 188 degrees Centigrade.
Step-by-Step Explanation:
Given:
Speed of sound at 0 degrees centigrade = 235 ms
frequency = f = 741 hz
wavelength = w = 0.47m
speed of sound wave = wavelength * frequency = 741 * 0.47 = 348.27 m/s
Using the formula for speed of sound at a specific temperature:
Speed of sound at T degrees Centigrade = Speed of sound at 0 degrees + 0.6 * T
When speed of sound is 348 m/s, the temperature is given by:
348 = 235 + 0.6(T)
T = (348-235)/0.6
T = 188 degrees Centigrade
