With the equation Vf = Vi + at, you can determine the unknown variable. I presume that gravity is the acceleration, so 30 = 10 + 9.8(t) —> 20 = 9.8(t) —> 2.040816 = t
Answer:
344Hz
Explanation:
First we need to more that the frequency will inky resonate in the portion not containing water. If the total length is 1m and the filled with water up to 75cm, the length of the air column will be 100cm - 75cm = 25cm
Fundamental frequency of a closed pipe fo = V/4L
V is the velocity of sound in air
L is the length of the air column
Given V = 344m/s
L = 25cm = 0.25m
fundamental resonant frequency = 344/4(0.25)
= 344/1
= 344Hz

1)Divergent boundaries – where two plates are moving apart.
2) Tectonic plates and Asthenosphere
3)Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys. ... Subduction zones occur where an oceanic plate meets a continental plate and is pushed underneath it. Subduction zones are marked by oceanic trenches.
4)New crust is being generated
Answer:
10 feet
Explanation:
In a standard procedure, there should be an approximate value of 10 feet between the water pipe and the Earth. This is to prevent the contamination of water and also the corrosion of the water pipe. Most pipes are made of iron and in the presence of water, there can be a chemical reaction between the iron and water in the presence of oxygen.
