<u>Answer:</u>
Lead
<u>Explanation:</u>
To get the density of the material, the formula would be:
mass divided by volume which is given by
.
Here in this problem, we are given a mass of
which occupies a volume of
.
So plugging the data in the above formula to find the density:
Density =
From the table, we can see that the material is Lead which has a density of 11.3c/cm^3.

i think these are correct if im wrong on a few im sorry. Hope this helps at least a bit. And if i do get some wrong you know just to pick the opposite answer.
Given:
F_gravity = 10 N
F_tension = 25 N
Let's find the net centripetal force exterted on the ball.
Apply the formula:
![\sum ^{}_{}F_{\text{net}}=F_1+F_2=F_{centripetal}](https://tex.z-dn.net/?f=%5Csum%20%5E%7B%7D_%7B%7DF_%7B%5Ctext%7Bnet%7D%7D%3DF_1%2BF_2%3DF_%7Bcentripetal%7D)
From the given figure, the force acting towards the circular path will be positive, while the force which points directly away from the center is negative.
Hence, the tensional force is positive while the gravitational force is negative.
Thus, we have:
![F_{\text{net}}=F_{\text{centripetal}}=F_{tension}-F_{gravity}=25N-10N=15N](https://tex.z-dn.net/?f=F_%7B%5Ctext%7Bnet%7D%7D%3DF_%7B%5Ctext%7Bcentripetal%7D%7D%3DF_%7Btension%7D-F_%7Bgravity%7D%3D25N-10N%3D15N)
Therefore, the net centripetal force exterted on the ball is 15 N.
ANSWER:
15 N
