The vibrating length of the air column is greater than the actual length of the organ pipe
B)comet nuclei are not uniform in composition
Answer:
dimension is 20ft*20ft*10ft
Explanation:
let a,a and h are length, width and height of given tank with square base.
volume = a*a*h
surface area =aa +2(ah+ah)
for weight to minimize, surface area is to be minimum i.e.
a = 20ft
now
at a = 20 ft
h = 10ft
hence dimension is 20ft*20ft*10ft
