Answer:
The magnitude of force is 1.86 N and the direction of force is towards the other wire.
Explanation:
Given:
Current flowing through each power line, I = 130 A
Distance between the two power lines, d = 40 cm = 0.4 m
Length of power lines, L = 220 m
The force exerted by the power lines on each other is given by the relation:

Substitute the suitable values in the above equation.

F = 1.86 N
Since the direction of current flowing through the power lines are opposite to each other, so the force is attractive in nature. Hence, the direction of force experienced by the power lines on each other is towards the each other.
Answer:
For two polarizing filters to block out all light passing through them, one filter should be rotated 90 degrees from the other.

0.03719 lbs/in³
Explanation:
Specific weight is given by multiplying the density of an object to the acceleration due to gravity.




So,

Answer:
Explanation:
it is a vector as it has a magnitude and a direction. If it was a scalar quantity it would just have a magnitude and would be 45 m. Acceleration is an example of a vector quantity
there are different types of power so ill show you all the examples of power.
