Answer:
44.2 mmHg
Explanation:
We have to apply the colligative property of lowering vapor pressure:
P° - P' = P° . Xm
where P' refers to vapor pressure of solution
P° refers to vapor pressure of pure solvent
Xm is the mole fraction of solute
Let's determine the mole fraction (moles of solute / Total moles)
Total moles = Moles of solute + Moles of solvent
Moles of solute → 15 g . 1 mol/18g = 0.833 moles
Moles of solvent → 100 g . 1mol / 46 g = 2.174 moles
Total moles = 0.833 + 2.174 = 3.007
Xm = 0.833 / 3.007 = 0.277
We replace data in the formula: 61.2 mmHg - P' = 61.2 mmHg . 0.277
P' = - (61.2 mmHg . 0.277 - 61.2 mmHg) → 44.2 mmHg
The first one you did wrong on the side its GG not GgThe second one is wrong to on the side it its Tt not TTthe third one is wrong to on the side its tt, not TTthe last one is wrong to is wrong to the top is RR and the side is rr P.S i did this 1 year ago :PPPPthat the one i did to and the other one too *sigh*

Answer: C, an apple staying at rest on the ground.
Explanation: When one or more unbalanced forces are acting on an object, it causes change (eg. the apple falling on the ground would be a result of gravity being stronger than the kinetic energy that the tree is putting on the apple). Even in D, the apple is not moving, but the tree branch is still exerting force to keep the apple hanging there.
PS: I studied net forces last year. Hope this helps!
Answer:
It allows the completion of the metamorphosis of the silkworm to its moth stage, whereas most silk harvesting requires the silkworms to be killed in their cocoon stage. No animals suffer or die for the silk to be produced, making it a favorable alternative to normal silk for those who do not believe in harming animals.
