<span>Force of the helicopter is equivalent to weight for this case. </span>Weight is calculated by multiplying the mass of
the object and the acceleration. For this case, the acceleration would be the
acceleration due to gravity which is equal to 9.81 m/s^2. We calculate as
follows:<span>
W = mg
<span>W = 1500 kg ( 9.81 m/s^2 )</span></span>
<span><span>W = 14715 N </span></span>
Answer:
<em>It is a chemical reaction in which the reactants form products and products react together to give reactants back. That means reversible reactions can go in both directions forward as well as backward direction.</em>
<span>There are three isotopes of hydrogen H-1, H-2, and H-3 all of these isotopes have "One Proton"
Hope this helps!</span>
I think it would be B
hope this works
