Explanation:
We know that the relation between volume and density is as follows.
Volume =
So, V =
=
Now, we will calculate the area as follows.
Area =
=
=
Formula to calculate the resistance is as follows.
R =
=
=
Thus, we can conclude that the resistance of given wire is .
Answer:
System D --> System C --> System A --> System B
Explanation:
The gravitational force between two masses m1, m2 separated by a distance r is given by:
where G is the gravitational constant. Let's apply this formula to each case now to calculate the relative force for each system:
System A has masses m and m separated by a distance r:
system B has masses m and 2m separated by a distance 2r:
system C has masses 2m and 3m separated by a distance 2r:
system D has masses 4m and 5m separated by a distance 3r:
Now, by looking at the 4 different forces, we can rank them from the greatest to the smallest force, and we find:
System D --> System C --> System A --> System B
