identical conducting spheres that are
actually well separated from one an-
other. Sphere W (with an initial
charge of zero) is touched to sphere Fig. 21-36 Problem 38.
A and then they are separated. Next, sphere W is touched to sphere
B (with an initial charge of -32e) and then they are separated.
Finally, sphere W is touched to sphere C (with an initial charge of
+48c). and then they are separated. The final charge on sphere W is
+ 18c. What was the initial charge on sphere .1?

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
