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
Answer:
453.25 MJ
Explanation:
The formula to find kinetic energy is :
E.k = ?
m = 0.56kg
v = 25mi./s which needs to be converted into metres per second
1mi./s= 1609.34m/s
25 mi./s = 40233.6 m/s.
E.k. = 0.5 × 0.56 × 40233.6²
e.k = 453247919.3J
E.k.= 453.25 MJ
