Answer:Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity.
Explanation:
Answer:
Explanation:
n = Refractive index of air = 1
= Refractive index of contact lens = 1.6
= Refractive index of cornea = 1.4
= Refractive index of fluid = 1.3
From Snell's law
The angle is the light traveling in the fluid behind her cornea is .
Answer:
Part a)
Part b)
So density of atmosphere at Martian Surface is very less than the density at Earth.
Explanation:
Part a)
As per ideal gas equation we know that
here we know that Martian atmosphere is equivalent to that of carbon
so we will have
now we will have
Part b)
Now for the earth surface the density of air is given for
so we will have
So density of atmosphere at Martian Surface is very less than the density at Earth.
