Answer:
The magnitude of the force that each wire exerts on the other will increase by a factor of two.
Explanation:
force on parallel current carrying wire, F = BILsinθ
where;
B is the strength of the magnetic field
L is the length of the wire
I is the magnitude of current on the wire
θ is the angle of inclination of the wire
Assuming B, L and θ is constant, then F ∝ I
F = kI

When the amount of current is doubled in one of the wires, lets say the second wire;

Also, if will double the amount of current on the first wire, then
F₁ = 2F₂
Therefore, the magnitude of the force that each wire exerts on the other will increase by a factor of two.
X2 = 60
/ 2 / 2
x = 30
Plus or minus square root 60
It is the number in front of the equation
-- When the man at the North end throws the ball, the canoe
accelerates to the North.
-- While the ball is in flight, traveling south by the length of the
canoe, the canoe moves northward at a constant speed.
-- If the man at the south end misses the ball and fails to catch it,
then the canoe continues moving south at a constant speed, even
after the ball has passed him.
-- If the man at the south end successfully catches the ball, then the
canoe accelerates south at that moment, and comes to rest in the water.
