There will be 13 new moons to occur in 2016 im pretty sure
Answer:
refractive index of plastic is 1.42
Explanation:
When light ray enters from one medium to other medium then due to transition of light it bends away or towards the normal, this phenomenon is known as refraction of light
So here we know that
here we have
now we have
The direction of the magnetic field between the two cylinders while the capacitor is charging is counterclockwise.
According to Maxwell's law of induction, a changing electric field induces a magnetic field, B given by the equation
∫B.ds = μεdΦ/dt where ds = path length of magnetic field, μ = permeability of free space, ε = permittivity of free space and dΦ/dt = rate of change in electric flux. The electric field in the cylindrical capacitor is directed from the inner cylinder to the outer cylinder since the inner cylinder is positive and outer cylinder negative.
For an electric current which increases, the rate of change of electric flux is positive and this produces a magnetic field in the clockwise direction.
Since in this case, we have an exponentially decreasing current, dΦ/dt is negative. Thus, this will produce a magnetic field opposite to that of an increasing current. So, the direction of the magnetic field would be counter clockwise.
So, the direction of the magnetic field between the two cylinders while the capacitor is charging is counterclockwise.

Because the move through water
Answer:
Gamma rays
Explanation:
The penetrating power of gamma rays is maximum as compared to beta and alpha rays. Gamma rays are nothing but the photons i.e. the packets of energy. Their energy range lies from kilo electron volts to 8 mega electron volts. It is emitted during the decay of many radioactive isotopes, such as U-238 and I-131. A large amount of energy is produced in decay of uranium 238.
Hence, the correct option is " gamma rays ".
