A coil of wire can become a temporary magnet if connected to a battery O True O False

Physics
1 answer:
GrogVix [38]3 years ago
4 0

Answer:

true

Explanation:

An Electromagnet is called as a temporary magnet, because electromagnet is made up of insulated copper wire wrapped around soft iron, which allows current to flow in it and at that moment iron gains it magnetic properties and when the current is switched off, then there will be no flow of current and hence iron loses its magnetic properties.  

Hence it works temporarily as long as electric current flows in a conductor and hence known as temporary magnet. .

If two tiny identical spheres attract each other with a force of 2.00 nn when they are 20.0 cm apart, what is the mass of each s
attashe74 [19]

The mass of each sphere is m=1.7kg

<h3>What is the mass?</h3>

The amount of matter in a particle or object is represented by the dimensionless quantity mass (symbolized m). The kilogram is the chosen unit of mass according to the International System (SI) (kg).

<h3>According to Given Information:</h3>

We'll apply the formula.

Now take note that the value we must discover is m1 = m2 = m. When m is solved for,

m=1.7kg is obtained using the formulas Fg = 2.0 109 N and G = 6.673 1011 N m2/kg2.

<h3>What is the force?</h3>

A force refers to the push or pull that such an object feels when it comes into contact with another object. A force is applied to each object when two things come into contact. The interaction between the two items stops when the force is no longer looks by either.
