Answer:
time of collision is
t = 0.395 s
so they will collide at height of 5.63 m from ground
Explanation:
initial speed of the ball when it is dropped down is
similarly initial speed of the object which is projected by spring is given as
now relative velocity of object with respect to ball
now since we know that both are moving under gravity so their relative acceleration is ZERO and the relative distance between them is 6.4 m
Now the height attained by the object in the same time is given as
so they will collide at height of 5.63 m from ground
The wavelength of the third resonance of the closed organ pipe is equal to the ratio between the speed of sound and the frequency of the 3rd harmonic:
The relationship between length of a closed pipe and wavelength of the standing waves inside is:
where n is the number of the harmonic. In this case, n=3, so the length of the pipe is

-- Jupiter is about 5.2 times as far from the sun as the earth is.
-- So when Jupiter and the EARTH are aligned in both orbits, Jupiter is about
(4.2) x (150 million kilometers) = 630 million kilometers
Time = (distance) / (speed)
The speed of light and radio is 300,000 km/second
Time = (630 million / 300 thousand)
<em>Time = 2,100 seconds</em>
That's 35 minutes.
Fossil fuels . . . coal, oil, natural gas
Among primitive cultures, wood is an important source.
Answer:
Part a)
distance = 112 miles
Part b)
current position = 112 miles from the position of town
Explanation:
Part a)
Since the distance marker is showing the distance between the town and the position of john at all time
so here we have
Part b)
Current position of John is given as
from the position of the town
