PLEASE HELP!!!!

8) The gravitational force is a force of attraction between two objects. It can be expressed mathematically as:

F = G m₁*m₂/d² ------(1)

m₁ and m₂ are the masses of two interacting systems

d = distance between them

G = gravitational constant

Thus according to equation(1), the gravitational force is directly proportional to the mass of the objects. Greater the masses, stronger will be the force of attraction.

In this case, the distance (d) and the one of the masses i.e. mass of earth would be the same for both situations. However, since an elephant would weigh more than a human, the gravitational force will be stronger between an elephant and earth.

9) Since the masses of spheres is the same, the gravitational force between the red and blue spheres would be the same as well, provided the distance d remains constant.

A certain radioactive isotope has a half-life of 5 days. If one is to make a table showing the half-life decay of a sample of th

Pepsi [2]

It will take 25 days for this substance to become 1gram from 32 grams.

<h3><u>Explanation</u>:</h3>

Radioactivity or radioactive decay is the process of formation of different element from one Radioactive element due to decay of the radioactive nucleus. The radioactive decay is a first order kinetic reaction. This reaction has a straight log C vs T graph.

Here in this particular reaction, the half life of the radioactive substance is 5 days. So within 5 days, the concentration of the substance becomes halved.

Now, in the sample the amount of substance present = 32 grams

The final amount of this sample = 1 grams.

So number of half lives needed for this decay = 5 half lives.

So number of days required for this decay = $5\times5$ =25.

So within 25 days, 32 grams of the substance becomes 1grams.
