Answer:
Below
Explanation:
To calculate the time it took for the cyclist to finish their race, you can you this equation :
time = displacement / velocity
Plug in your values....
time = (100 mi) / (22 mi/h)
= 4.54545454.... hours
As for sig figs in this question you would need to round this answer to 1 sig fig because 100 only has 1 sig fig. (you round to the lowest # of sig figs in the question)
= 5 hours
It took the cyclist 5 hours to complete their race
Hope this helps! Best of luck <3
Answer:
Period of one vibration = 0.00215 second (Approx.)
Wavelength {Is speed of sound is 343 m/s] = 0.736 m (Approx.)
Explanation:
Given:
Frequency of wave = 466 Hz
Find:
Period of one vibration
Wavelength {Is speed of sound is 343 m/s]
Computation:
Period of one vibration = 1/F
Period of one vibration = 1 / 466
Period of one vibration = 0.00215 second (Approx.)
Wavelength = Velocity / Frequency
Wavelength {Is speed of sound is 343 m/s] = 343 / 466
Wavelength {Is speed of sound is 343 m/s] = 0.736 m (Approx.)
Answer:
88 m/s
Explanation:
To solve the problem, we can use the following SUVAT equation:

where
v is the final velocity
u is the initial velocity
a is the acceleration
d is the distance covered
For the car in this problem, we have
d = 484 m is the stopping distance
v = 0 is the final velocity
is the acceleration
Solving for u, we find the initial velocity:
