Climate change from the use of metals i think sorry if i’m wrong that one seems the most ligit to me
A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one thus equalizing the concentrations on each side of the membrane. I hope this helps :D

Hi, There!
<em>Drinking energy drinks make people more hyper. What is the independent variable and the dependent variable?</em>
<em>The independent Vairable is the people drinking the energy drinks.</em>
<em>The Dependent variable is is the result which makes people more hyper</em>
Hope this Helps!
The half-life of cesium-137 is 30 years. Suppose we have a 150 mg sample. The masses (in mg) that remains after t years A=150/2^t/30yrs
<h3>what do you mean by half-life?</h3>
A substance's half-life is the amount of time it takes for half of it to decompose.
<h3>What is a half-life example?</h3>
Half-life is the length of time it takes for half of an unstable nucleus to go through its decay process. A radioactive element's half-life decay time varies depending on the element. For instance, carbon-10 has a half-life of only 19 seconds, making it impossible to discover in nature. On the other hand, uranium-233 has a half-life of almost 160000 years.
When n half-lives have passed, the formula for estimating the amount still left is:-
A=A°/2^n
where,
A=initial amount
A°=remaining amount
n=t/t_{1/2}
A=150/2^t/30yrs
