F = m · a
In order to accelerate 82 kg upward at the rate of 3.2 m/s², a NET upward force of (82kg · 3.2m/s²) = 262.4 Newtons is required.
But if the object is on or near the surface of the Earth, then there's a downward force of (82kg · 9.8m/s²) = 803.6 N already acting on it because of gravity.
So you need to apply (803.6N + 262.4N) = <em>1,066 Newtons UPward</em>, in order to cancel its own weight and accelerate it upward at that rate.
many answers to this question so chose whatever you link:
- urbanisation -> more people, humanity keeps on living, more job opportunities etc
- source of income for farmers
- source for food (farming)
- source for trees (eg, to create wood (houses), or to use logs for fire)
The numbers in front of a compound is called a subscript. It shows how many atoms of that specific element it is next two that is involved in the reaction or is in that compound.
The answer is then D.
Coefficient is found behind the compounds, the charges are written above.
I think it’s C but I’m not sure:/
