Answer:
C. This is because he is asking him to disregard what his parents are saying and listen to his own values. This is not morally wrong, just the answer that works in that situation.
For one thing, hydrogen gas or fuel is really expensive compared to present diesel and gasoline. There's no point in actually investing in them since economy will not improve otherwise. Gasoline stations will also have to adjust to how tricky hydrogen gas will be to support and store with ease. It's dangerous also to the driver, passengers and our environment.
<span>Integrate a to get v and use initial data for v to evaluate the constants of integration.
v = [(3/2)t^2 + Ci]i + [2t^2 + Cj]j
When t=0, v = 5i + 2j, hence Ci=5, Cj=2
So v = [(3/2)t^2 + 5]i + [2t^2 + 2]j <==ANS
(b)
Integrate v to get r and use initial data for r to evaluate the constants of integration:
The result is:
r = [0.5t^3 + 5t + 20]i + [(2/3)t^3 + 2t + 40]j <==ANS
Set t=4 in the above expression to evaluate (c)
Convert the result of (c) to polar form to evaluate (d)</span>
The formula for ethane is C2H6. (the 2 and 6 are supposed to be subscripts) they show the number of atoms per element. So there are two carbon atoms and six hydrogen atoms in ethane. The subscript in a chemical formula represents the amount of that atom in that compound's formula. <span>In chemistry, no subscript indicates 1 of that particular atom. HCl contains 1 atom of hydrogen and 1 atom of chlorine, whereas H20 contains 2 atoms of hydrogen and 1 atom of oxygen.It should be noted, however that this does not necessarily hold true for empiracle formulas, since these have been reduced to the simplest whole number ratio and do not necessarily reflect the number of each element present in an actual molecule.
I hope this helps you! Good luck :)</span>
