Answer:
B) shrinks
Explanation:
The magnetic force is a force exerted between two magnets, or two magnetic materials, or also on an electric charge moving in a magnetic field.
If we talk about magnetic material, the magnetic field they generates can be represented using a dipole: essentially, they have a north pole (where the lines of the field go out) and a south pole (where the lines of the field go in).
Also, the lines spread apart as we move away from the magnet itself. This means that the strength of the field (and so, the intensity of the force) decreases as we move away from the magnet.
Using this description, we can now understand that when we move the paper clip further from the magnet, the force exerted on the clip decreases, as the magnetic field becomes weaker. So, the correct answer is B.
A Cyclone is a hurricane.
1.2 x (2.2 x 10⁵) = 264,000 Ω
0.8 x (2.2 x 10⁵) = 176,000 Ω
With a 'nominal' value of 220,000 Ω, it could actually be anywhere <em>between 176,000Ω and 264,000Ω</em> .
Explanation:
The forces acting on a massless object (spring, hook, string or wire, if considered massless) will always balance. Balanced forces acting on an object cause it to compress or stretch. The forces acting on a mass will never cancel.
