To solve this problem we need to consider the concept about Ampere's Law.
The Ampere's law say that,
Where,
F= Mangetic field
Permeability of free space
I =current
R= Radius from the wire in meters.
A) At the first case the force on wire is repulsive, replacing our values
In repulsive direction.
B) At the second case de Force flow in the same direction, then we have,
In attractive direction
I’m pretty sure A is the answer
Answer:
D. The net force on an object applied over a distance
Explanation:
Work can be defined as the product of force multiplied by a distance
Where
F = force [Newtons]
d = distance = [meters]
Therefore:
Work = F * d
Work in units of Joules [J]
Answer:
0.176m from the flagpole, westward.
Explanation:
Let the Eastward be the positive direction. So initially runner A is at position -6km, running with velocity of 9km/h while runner B is at position 5km running at a velocity of -8km/h. We can conduct the following equation for their distances over the same time t
When A an B meets, they are at the same position and at the same time. So
So where they meet is 0.176m from the flagpole, westward.
