If the amount of electrical energy is 50 Joules before the conversions, then it would be 50 Joules after the conversion.
According to law of conservation of energy, we cannot create or destroy energy so it remains constant
Hope this helps!
Answer:
Those substances which can conduct electricity are called conductors, while those substances which don't conduct electricity are called insulators.
Resistance is the obstruction provided by the material through which the current passes,so since conductors conduct electricity and insulators don't,so the obstruction i.e resistance provided by the conductor must be less,while insulators being unable to conduct electricity,has very high resistance.
Example of conductor is copper
Example of insulator is plastic
Answer:
the answer is B ( Argon (Ar) )
Answer:
an active galaxy is the galaxy that produces large amounts of energy in a very small volume of space.
Explanation:
active galaxies such as the M87 gives out extremely bright straight jets having speeds close to the speed of light providing the evidence that power in active galaxies is concentrated in a small region. this power from such a small region cannot be generated throught nuclear fusion as it happens in stars, this is the region why the concentration of matter in the center of this galaxies is not made up of stars.
