The answer is C, because there are only so many elements therefor you can have only so many compounds.
Answer:
D
Explanation:
F = G m1 m2 / r^2 now double r
F = G m1m1/ (2r)^2
F = 1/4 G m1m2/r^2 <===== this is 1/4 of the original
Explanation:
Using Coulomb's law, the relation between force and charge is as follows.
F =
In the given case, = q
Hence,
F =
Squaring on both the sides, we get
q =
=
= C
=
Thus, we can conclude that magnitude of the charge on each grape is .
The apparent magnitude<span> (m) of a celestial object is a number that is a measure of its brightness as seen by an observer on Earth. The brighter an object appears, the lower its magnitude value.</span>
