Total distance between Sally's house and mall = 10 kilometers
Distance covered during half way drive = Kilometers
Now, she goes back to her home.
Distance covered going back home = Kilometers
Now, she drives from home to mall.
Distance covered from Sally's home to mall = 10 kilometers
Hence, the total distance Sally traveled = 5 + 5 + 10
Total distance Sally traveled = 20 kilometers
Hence, the answer is 20 kilometers

Answer:
2 x 10⁻¹²F
Explanation:
Capacitance is defined as the ration of charge (q) on either plates to the potential difference V between them.
C =
Where q is the charge on the plates
V is the potential difference
From the given parameters:
Charge on plate, q = 2.0 x 10⁻¹⁰C
Potential difference across the plate = 100V
Unknown parameter:
Capacitance of the system = ? = C
Solution
Capacitance = 2.0 x 10⁻¹⁰/100 = 2 x 10⁻¹²F
Answer:
C

Answer:
1.117935:1
Explanation:
Since the wires are of the same material, they will have the same resistivity .
The cross-sectional area of the of a wire is given by;
where d is the diameter of the wire.
Also, the relationship between resistance R, cross-sectional area A and length l of a wire is given as follows;
Since the resistivity same for both wires, say wire 1 and wire 2, we can wreite the following;
Hence from eqaution (3), the ration of wire 1 to 2 is expressed as;
Given;
We then use equation (1) to fine the ratio of the area to
bearing in mind that
This ratio gives 0.8281. Substituting this into equation (5), we get the following;
