<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>
The answers to your questions are 6 and 4. Trust me my friend.
Hope this helps! God bless

If he was 30.8% too low, it means that he was at 69.2% of the boiling point needed. So 50o C is 69.2% of total.
In order to know what 100% is, you can divide the number by it's percentage and then multiply it by a hundred.
So: 50/30.8=1.623
1.623*100=162.3
So the correct boiling point of the liquid he was working with in the lab is 162.3 oC
What you have to keep in mind is that
pH = - log[H+]
so 3.75 = -log[H+], we get [H+]=
,
that is [H+]≈1.77827941×
(i see this result on calculator)
this is just what you want!
Benedict's solution is used to test simple sugars, such as glucose. It is blue solution, when sugar is present, it turns to orange / brick red. Depends on the concentration of sugar.
