<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:
a - carbon is not toxic to living things
Explanation:
The reason carbon dating works is that the fresh carbon-14 gets mixed in with the rest of the carbon in the atmosphere and, since it's chemically identical to regular carbon, gets worked into whatever is presently absorbing atmospheric carbon
Covalent bonding!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:209.53
Explanation:
Molar concentration=moles/Volume. Volume is given as 750mL which can be converted as 0.75l,so moles of CuBr2 is molar concentration ×Volume= 1.25×0.75=0.9375
Mole =mass of CuBr2/molecular Mass of CuBr2.
Molecular Mass of CuBr2 is 63.5+80×2=223.5(mass number of Cu=63.5 and Br=80).
So mass required= 223.5×0.9375=209.53g
