If objects with a greater mass have greater gravitational pull, why is our solar
STatiana [176]

Answer:

It's too far away

Explanation:

According to classical mechanics, gravitational pull is inversely proportional to the distance squared; as the distance increases, the gravitational pull decreases at a faster and faster rate. Since Alpha Centauri A is a few lightyears (Tens of trillions of kilometers away), without even needing to calculate the force of gravity, it is very miniscule.

Much like its household namesake, a molecular sieve utilizes differences in what property of substances to separate the componen
nlexa [21]

Answer: B . particle size

Explanation:

Let's begin by explaining that a molecular sieve is a device, whose composition allows the absorbtion of molecules that are small enough to pass through its pores, since it is made up of small pores of a precise and uniform size.

Thus, very small molecules manage to pass through the pores of the sieve, while large ones do not.

So, based on this premise, a molecular sieve separates the substances by their size.

Hence, the correct option is B.
