Answer:
The magnitude of force per unit length of one wire on the other is 
and the direction is away from one another
The magnitude of force per unit length of one wire on the other is and the direction is towards each other.
Explanation:
= Vacuum permeability = 
= Current in first wire = 2.9 A
= Current in second wire = 5.3 A
r = Gap between the wires = 11 cm
Force per unit length
The magnitude of force per unit length of one wire on the other is and the direction is away from one another
The magnitude of force per unit length of one wire on the other is and the direction is towards each other.
A concave mirror is used in the design of solar furnaces because they converge the parallel sunrays at a point. This helps to increase the temperature of the furnace.
If the radius of a circle of area A and circumference C is doubled, <u>the new circumference</u> of the circle, in terms of C, <u>will be</u> equal to 2C.
The area (A) of a circle is given by:
(1)
And a circumference (C) is:
(2)
Where:
r: is the radius
<u>If the radius</u> of a circle and circumference <u>is doubled</u>, the new circumference of the circle is:
Therefore, the new circumference of the circle in terms of C is equal to 2C.
