Answer:
4.06 Hz
Explanation:
For simple harmonic motion, frequency is given by
where k is spring constant and m is the mass of the object.
Substituting 0.2 Kg for mass and 130 N/m for k then

Answer:
The work done is 5136.88 J.
Explanation:
Given that,
n = 1.90 mol
Temperature = 296 K
If the initial volume is V then the final volume will be V/3.
We need to calculate the work done
Using formula of work done

Put the value into the formula



The Work done on the system.
Hence, The work done is 5136.88 J.

Answer:
An electromagnet is a device which moving electric charges(current) in a coil of wire create a magnet. Electromagnets can easily be turned off and on because it is a electromagnet. When current flows through a wire, a magnetic field is produced around a wire and create an electromagnet. The coils are always made of copper wire because copper is a good conductor of electricity.
Explanation:
Tin is very weakly attracted to magnets, but is not ferro magnetic. I would say it is magnetic even though it is very weakly attracted to it.
