The answer for that is True.
When you notice the soft sound of rain on the rooftop, it has crossed a perceptual line called you absolute threshold for detecting an auditory sound.
I believe that is the correct answer.
I hope this helps you and have a great day! :-)
Answer: 26.7 s
Explanation:
Given
Width of the river, = 0.2 km = 200 m
Speed of the rover, = 3 m/s
Speed of the boat, = 8 m/s
From the question, the boat would have to move westward. In moving westward, the angle will be
tan A = 3/8
tan A = 0.375
A = tan^-1(0.375)
A = 21°
Then, the velocity of the boat northward will be
v(north) = 8 cos 21
v(north) = 8 * 0.934
v(north) = 7.47 m/s
Therefore, the time taken would be
t = 200/7.47
t = 26.7 s
Answer:
It will take 666.7 seconds for him to complete 2 km run.
Explanation:
1 km → 1000 m
2 km → 2000 m
Here the distance is 2000 m and speed is 3 m/s
