Answer:
By using magnet.
Explanation:
Put sand and zinc in the bowl.
Take a magnet an bring it close to the bowl.
The zinc from the sand will be attracted towards the magnet.
In this way it will be separated.

Answer:
The liquid level will rise in Side A and drop in Side B.
Step-by-step explanation:
The membrane is impermeable to sucrose, but permeable to sucrose and water.
<u> Side A </u> <u> Side B </u>
2 M sucrose 1 M sucrose
1 M glucose 2 M glucose
(a) Ignoring osmotic effects
The glucose will diffuse spontaneously from the side with higher concentration to that of lower concentration until equilibrium is established. There is no change in volume on either side.
At this point, we have
<u> Side A </u> <u> Side B </u>
2 M sucrose 1 M sucrose
1.5 M glucose 1.5 M glucose
=====
(b) With osmotic effects
The solute concentration on Side A is greater than on Side B.
Water will diffuse into Side A.
The liquid level will rise in Side A and drop in Side B.
Answer:
d
Explanation:
I believe the answer to this question is d , I believe this as the question doesn't explain properly the surface under the boulder. it is questionable as the question is not clear though I believe this as there must be friction under the boulder stopping it from moving.
I think the answer is Joule.
As an amount of energy (being transferred), the SI unit of heat is the joule (J).
