Answer:
The time required is 10.078 hours or 605 min
Explanation:
The formula to apply here is ;
K=(d²-d²₀ )/t
where t is time in hours
d is grain diameter to be achieved after heating in mm
d₀ is the grain diameter before heating in mm
Given
d=5.5 × 10^-2 mm
d₀=2.4 × 10^-2 mm
t₁= 500 min = 500/60 =25/3 hrs
t₂=?
n=2.2
First find K
K=(d²-d²₀ )/t₁
K={ (5.1 × 10^-2 mm)²-(2.4 × 10−2 mm)² }/ 25/3
K=(0.051²-0.024²) ÷25/2
K=0.000243 mm²/h
Re-arrange equation for K ,to get the equation for d as;
d=√(d₀²+ Kt) where now t=t₂
Answer:
A. Bow
Explanation:
Registration number is an evidence or authentication of registration of a vessel or vehicle. This number is very important when an emergency occurs and there is a need to trace the vessel to the owner. And this should be displayed on a vertical surface or a surface where easy view is achievable.
So it is recommended that registration numbers be displayed on the bow of the vessel. The number should be displayed in such a way that it could be read from left to right.
