Waves A fisherman notices that wave crests pass the bow of his anchored boat every 3.0 s. He measures the distance between two crests to be 6.5 m. How fast are the waves traveling? 2. A sound wave in air has a frequency of 262 Hz and travels with a speed of 343 m/s. How far apart are the wave crests (compressions)? io signals have frequencies between 550 kHz and 1600 kHz and travel with...
An event observed by a stationary observer for 12 seconds. What is the time interval of the event, according to an observer who moving at a speed of 0.8 c (c = the speed of light).
Please show all steps! Much appreciated, thank
you!

can you please help me with these 1. A wave has a period of 0.0002727343 seconds and a wavelength of 248.75 cm. What is the velocity of the wave in m/s? 2. The frequency stamped on a tuning fork is 230 Hz. The actual frequency you obtained through measurement is 232 Hz. What is the percent error of the stamped value? 3. What is the speed of sound in air under normal conditions in m/s? 4. A sound wave has...
Please help in c++, follow the instructions, please. try to use pass by reference and pass by value if you could Description: Write a program that will input wind speed and temperature and output the wind-chill factor. W = 35.74 + 0.6215 ∗ T − 35.75 ∗ V 0.16 + 0.4275 ∗ T ∗ V 0.16 Your program should use at least 2 functions in addition to main. One that uses pass by reference parameters and prompts the user for...
I'm not sure how to answer. how do I figure out the
wavelength? or the speed of the wave? can someone please help me
answer these 3 questions? I would appreciate it.
5. For the waves pictured below (physics.stackexchange.com); a. Determine the wavelength. b. If 637 waves pass a point every 241.0 seconds, determine the period and the frequency of the wave. c. What is the speed of the wave?
#22 Suppose cars pass an intersection at a rate of 120 per hour. What is the probability that we need to wait between 25 and 30 seconds for the next car to pass? Please round your answer to 4 decimal places. Expert Answer
Bruce runs a 100m race. 5 seconds after the race
started Bruce is 45 mi from the starting line and reaches his max
speed, he runs at his max speed for the rest of the race. Bryce
notices that he is 77 meters from the starting line 9 seconds after
the race started.
a. what is Bryce's max speed
b. suppose Bryce runs for an additional Z seconds
after reaching his max speed
i. how far will Bryce travel during...
Waves on a lake pass under a floating bird causing the bird to bob up and down with a period of 2.5 seconds. If the distance from wave trough to wave trough is 3.0 meters, what is the speed of the wave? a) 0.21 m/s b) 1.2 m/s c) 1.5 m/s d) 2.1 m/s E) 1.9 m/s
Suppose a computer manufacturer claims that their average customer support call wait time is 30 seconds. We believe this to be an exaggeration of their efficiency and we wish to test this at a 99% confidence level. A random sample of 50 phone calls yields an average waiting period of 45 seconds, with a standard deviation of 15 seconds. Set up and conduct a test of the hypothesis that µ = 30 seconds against an appropriate alternative hypothesis.
