The currents in the wires are in opposite directions.
- Two long parallel wires separated by a distance 'r' having current and have force per unit length which is given by .....(1) where is permittivity of free space whose value is .
If the current flowing through the wire are in same direction then they the wire attract each other and if the current flowing through the wire are opposite in direction then they the wire repel each other .
As it is given that two wires repel each other which means that current in the wires are in opposite direction .
Hence current flowing through wires are opposite in direction.

Answer:
lungs, bronchi, trachea, larynx, pharynx, and nose.
Explanation:
The important parts of the respiratory system are lungs, bronchi, trachea, larynx, pharynx, and nose.
The respiratory system helps in bringing in oxygen in our body and taking out carbon dioxide from our body.
<em>The question is incomplete and doesn't have any requirement. I'm computing the angle at which the dart should have been thrown to hit in the center of the target</em>
Answer:
The dart should be thown with an angle of elevation of
Explanation:
<u>Horizontal and Diagonal Motion</u>
When an object is launched horizontally, its initial vertical speed is zero and the horizontal component remains the same in time. If the initial velocity forms an angle with the horizontal, then the vertical velocity has an initial value which can be positive or negative depending on the angle (above or below the horizontal).
The dart is thrown horizontally and when it reaches the target, 5 meters away, the center of the target was missed by 0.15 meters below. The question doesn't have any requirement, but I'll assume you want to know at what angle should the dart be thrown at the same speed, to be exact on target.
Let's start with the original horizontal launching. The distance x is computed as
The distance y is
We need to find the value of , given x and y. Solving for t in the last equation
Replacing in x
Solving for
Now, let's suppose we try to reach the center of the target by throwing the dart at the same speed but with a certain angle above the horizontal. That way, the formulas for x changes to
Replacing the value of
Operating
Simplifying
Solving for the angle
