The study and practice of map making is called Cartography.
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:
A & B
Explanation:
A & B Would be the right answer since Morse code cannot be represented through the height of the fire.
Answer:
Explanation:
The given differential equation is
and y(0) = 0, y(L) =0
where T and ρ are constants
The given rewrite as
auxiliary equation is
Solution of this de is
y(0)=0 ⇒ C₁ = 0
y(L) = 0 ⇒
we need non zero solution
⇒ C₂ ≠ 0 and
solution corresponding these values
Acceleration = (change in velocity) / (time for the change)
Change in velocity = 59.43 m/s East
Time for the change = 0.312 s
Acceleration = 190.5 m/s^2 East
