One way is the spinning of the wheels can be used to charge a battery. Just like with a generator, you can convert the rotational mechanical energy of the wheels spinning into electrical energy due to Faraday’s Law of Induction if there are magnets on the wheels.
Answer:
0.0016 cm
Explanation:
= Thermal coefficient of expansion of brass =
= Thermal coefficient of expansion of glass =
= Change in temperature =
= Initial radius = 4 cm
Change in radius of material is given by
Difference in radii of the lid and jar
The size of the gap is 0.0016 cm or 0.000016 m
Answer:
Refractive index = 1.15
Explanation:
As we know for constructive interference of reflected light the path difference of two reflected light rays must be integral multiple of the wavelength
so here we have
now here we know that
now we have
Brain & spinal cord makes up the nervous system
