<span>Slow moving vehicles must display reflective emblem at the rear to warn of their low speed.
The sign consists of a triangle and the primary purpose is to prevent any sad incident to happen, as slow moving vehicle (SMV) can cause serious accidents due to the less visibility at various times, therefore the sign must be visible enough. </span>
I believe the answer is convection!
Answer: The charges on cation and anion balances each other.
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Thus 
combines with two 
ions to give neutral

Answer:
0.28 year
Explanation:
Heat lost through new window per year = heat loss through a window / R- value = (10 MMBTU/year × 2) / 7 = 2.86 MMBTUs/yr
Reduction in heat lost per year = heat loss through a window - Heat lost through new window per year = 10 MMBTUs/yr - 2.86 MMBTUs/yr = 7.14 MMBTUs/yr
Savings in energy cost per year = Reduction in heat lost per year × heating price = 7.14 MMBTUs/yr × $10/MMBTU = $71.4 / yr
Payback period = cost for filling Argon / Savings in energy cost per year = $20 / $71.4 /yr = 0.28 yrs
