A certain orthodontist uses a wire brace to align a patient's crooked tooth as in the figure below. The tension in the wire is adjusted to have a magnitude of 21.12 N. Find the magnitude of the net force exerted by the wire on the crooked tooth.
Fnet=2(Tension of Wire)sin14
=2(21.12N)sin14
=10.219
Well, looks like this orthodontist is really pulling the strings, or should I say, wires! Anyway, to find the magnitude of the net force exerted by the wire on the crooked tooth, we'll need to consider the tension in the wire, which is 21.12 N.
Now, since we're dealing with a wire brace, we can assume that the tension in the wire is the only force acting on the tooth. So, the magnitude of the net force exerted by the wire on the tooth is simply the tension in the wire, which is 21.12 N.
To put it humorously, the wire is giving that crooked tooth a good tug, straightening it out with a force of 21.12 N!
Hope that helps, and remember, always keep your teeth in line, both figuratively and literally!
To find the magnitude of the net force exerted by the wire on the crooked tooth, we need to consider the tension in the wire.
The tension in the wire represents the magnitude of the force exerted by the wire on the crooked tooth. So, the magnitude of the net force exerted by the wire on the crooked tooth is equal to the tension in the wire.
Therefore, the magnitude of the net force exerted by the wire on the crooked tooth is 21.12 N.
To find the magnitude of the net force exerted by the wire on the crooked tooth, we can apply Newton's second law of motion, which states that the net force on an object is equal to the mass of the object multiplied by its acceleration.
In this case, the wire brace is applying a tension force on the tooth to align it. The tension force is directed along the length of the wire brace.
Since the tooth is not accelerating (assuming it's in equilibrium), the net force on the tooth must be zero. Therefore, the magnitude of the net force exerted by the wire on the tooth is equal to the magnitude of the tension force.
Given that the tension in the wire is 21.12 N, the magnitude of the net force exerted by the wire on the crooked tooth is 21.12 N.
