In a game of tug-of-war, a rope is pulled by a force of 182 n to the right and by a force of 110 n to the left. what is the magnitude and direction of the net horizontal force on the rope?

tex]\sum F=72N[/tex]

Explanation:

We assume that right side is positive, and left side is negative, which is the normal convention. Then, to calculate the net force applied on the rope, we use Newton's second law: . In words, the net force is the sum of all forces that are being applied, in this case, those forces are:

Therefore, the net force is the difference between forces, because they are being applied in opposite directions:

This result means that the movement is to the right-positive side, basically, right side team wins.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
