From the basics conversions:
1 nanogram is equivalent to 1 * 10^-15 megagrams

To convert 7.02 * 10^-10 nanograms to megagrams, all you have to do is cross multiplication as follows:
1 nanogram ................> 1 * 10^-15 megagrams
7.02 * 10^-10 nanograms ...............> ?? megagrams

megagrams = (7.02*10^-10 * 1*10^-15) / (1) = 7.02 * 10^-25 megagrams

Which has more mass: an armful of feathers or an armful of lead? which has more volume: a kilogram of feathers or a kilogram of
valina [46]
Mass is related to weight. It measures the resistance of the substance to acceleration when a net force is applied.
Therefore: armful of lead has more mass

volume measures the amount of 3-dimensional space that an object occupies.
Therefore: kilogram of feather has more volume as it is less dense.

density is the mass per unit volume. Since armful of lead has more mass than a handful of feathers, while kilogram of feather has more volume than a kilogram of lead.
Therefore: kilogram of lead has higher density.

What is the pressure of a gas that began at 38 torr, and 500L and is changed to occupy a volume of 677 L?
qwelly [4]

Answer:

P₂ = 28.5 torr

Explanation:

Given data:

Initial pressure = 38 torr

Initial volume = 500 L

Final volume = 677 L

Final pressure = ?

Solution:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = Initial volume

P₂ = Final pressure

V₂ = Final volume

Now we will put the vales in formula.

P₁V₁ = P₂V₂

P₂ = P₁V₁ /V₂

P₂ = 38 torr × 500 L / 667 L

P₂ = 19000 torr. L / 667 L

P₂ = 28.5 torr

How much force is required to lift a rock a vertical distance of 8 m if 80 j of work were done
yanalaym [24]

we have

work done (W)= force(F) × displacemen(s)

or, 80= F× 8

or, F= 10 N

therefore, 10 N force is required to lift the rock.

What do kinetic and potential energy have in common
adell [148]
Just simply... they both are energy.
Use a bow and arrow as an example:
When you pull back an arrow, potential energy or PE is stored in the string and the limbs of the bow.
When you release the the arrow, energy is being transferred from the bow to the arrow. The arrow now has kinetic energy or KE, this means that the energy is being used by the arrow.
