Answer:
0.334 m
Explanation:
The magnetic field due to current in a straight thin wire,
, is given by

where
is the permeability of free spave with value
and
is the distance from the wire.

Substituting the values from the question,


Answer:i
9E13 ELECTRONS
Explanation:
First we find the number of charges in two hrs
Which is - 2x 7200=- 14400NC
So no of electrons is now q/e
-144x10^-7/-1.6*10^-19
= 9*10^13
The answer would be that the plane would move upward and to the right! Hope this helps, message me if you need more help!

Answer:
A
Explanation:
The slope of the graph has the units of vertical axis divided by horizontal axis. This means that the slope of a distance vs time graph is distance/time, or velocity.
Slope is calculated by "rise over run" so C is incorrect.
Since the slope represents velocity, a constant slope equates to a constant velocity, hence B is incorrect. Same reasoning for D being incorrect: if the slope is zero, the object is not moving.
