The action that will directly affect the gravitational force between two objects is increasing the pressure on the objects (option B).

<h3>What is gravitational force?</h3>

Gravitational force is a very long-range, but relatively weak fundamental force of attraction that acts between all particles that have mass; believed to be mediated by gravitons.

Gravitational force can also be referred to as the force due to gravity of a planet.

The gravitational force between two objects can be affected by the following factors:

  • Increase in pressure
  • Increase in temperature
  • Increase in speed of objects

Therefore, the action that will directly affect the gravitational force between two objects is increasing the pressure on the objects.

Aminosyn is an amino acid often times used in tpn orders to provide protein for cellular repair and growth. a physician writes a
love history [14]
I think theres a few methods to do it, but this is probably the most efficient.

Physician has prescribed 2.5% of 500ml
Actual amount of Aminosyn in this prescription is
500*0.025= 12.5ml of Aminosin

Therefore you need to ensure when you pour your solution of the 8.5% Aminosyn, it has 12.5 ml of Aminosyn.

To work out how much 8.5% Aminosyn you should pour, you must think of the 12.5ml as 8.5%

Therefore 1% = 12.5/8.5= 1.470588

Therefore the amount of 8.5% solution you need to pour is 100* 1.470588= 147.1ml

Then make up the rest(352.9ml) by adding distilled water. You now have 500ml of 2.5% aminosyn.
