Answer:
The density of Saturn is 686.81 kg/m³.
Explanation:
Mass of Saturn, 
Volume of Saturn, 
Density of Saturn is given by its mass divided by its volume i.e.
So, the density of Saturn is 686.81 kg/m³.
The density of water is 1000 kg/m³. It is clear that the density of Saturn is less than water.
The speed of an electron when it moves in a circular path perpendicular to a constant magnetic field is 8.88 x 10^7 m/s.
The angular momentum(L) of an electron moving in a circular path is given by the formula,
L = mvr ........(i)
We know that the radius of the path of an electron in a magnetic field is
r = mv/qB
Putting this value in equation (i),
L = mv x mv/qB
or L = (mv)^2/qB
Putting the given values in the above equation,
4 x 10^-25 = (9.1x10^-31)^2 x v^2/ 1.6 x 10^-19 x 1 x 10^-3
v comes out to be 8.88 x 10^7 m/s.
Hence, the speed of an electron when it moves in a circular path perpendicular to a constant magnetic field is 8.88 x 10^7 m/s.

mass/volume = density.
if bigger than water, sinks
less than water floats.

Answer:
n = 1.5
Explanation:
The speed of light in vacuum is 300000000 m/s
The speed of light in glass is 200000000 m/s
We need to find the refractive index of the glass.
We know that, the ratio of speed of light in vacuum to the speed of light in medium is equal to refractive index of the medium.
So, the refractive index of the glass is 1.5.
