Answer:
A. 
B. P ≈ 0
Explanation:
In order to calculate the magnetic field strength we have to use the magnetic field strength of a straight wire.
(eq. I)
B = magnetic field strength at distance d
I = current (A)
mi = represented by the greek letter μ, represents the permeability of the free space, which is: 4 × π 10^(-7) T m/A
d = distance from the wire
By replacing the values in eq I, we have the following:
(eq II)
The earth magnetic field in the surface variates from 25 to 65 microteslas. Thus:
P = Percentage from the wires/percentage of the earth
∵
∴
P ≈ 0
If the forces on an object are balanced (or if there are no forces acting on it), this is what happens:
a stationary object stays still
a moving object continues to move at the same speed and in the same direction
It has many different colors without gaps.
There is no list but I would say a landslide.
Answer:
thermal conductivity = 0.2906 W/m.K
Explanation:
thermal conductivity = 0.168 BTU/h.ft⁰F
1 BTU/h.ft⁰F = 1.7295772056 W/m.k
0.168 BTU/h.ft⁰F = 0.168 * 1.7295772056 W/m.k
0.168 BTU/h.ft⁰F = 0.2906 W/m.k
