Answer:

Hello, A magnetic field is created by moving

It is known that current is the flow of electrons or electric charges.

And when electric current flows through a wire or material then it generates a magnetic field outside the material.

where        B = magentic field

       = magnetic permeability

                  r = radial distance

Therefore, we can conclude that a magnetic field is created by a charged particle that is moving. <u><em>Have a Great Day!</em></u>

PolarNik [594]

<u>Answer:</u> The correct answer is Option C.

<u>Explanation:</u>

Precision refers to the closeness of two or more measurements to each other.

For Example: If you weigh a given substance five times and you get 3.2 kg each time. Then the measurement is very precise.  

Accuracy refers to the closeness of a measured value to a standard or known value.

For Example: If the mass of a substance is 32 kg and one person weighed 31 kg and another person weighed 29 kg. Then, the weight measured by first person is more accurate.

According to the question:

Mass weighed by Mary = 10.00 g

Mass weighed by Tommy = 10 g

As, mass weighed by Mary is reported upto 2 decimal places. Thus, it is more precise.

Hence, the correct answer is Option C.
