Answer:
The distance is
Explanation:
From the question we are told that
The wavelength of the light is
The distance between the slit is
The between the first and second dark fringes is
Generally fringe width is mathematically represented as
Where D is the distance of the slit to the screen
Hence
substituting values
Answer:
a
The orbital speed is
b
The escape velocity of the rocket is
Explanation:
Generally angular velocity is mathematically represented as
Where T is the period which is given as 1.6 days =
Substituting the value
At the point when the rocket is on a circular orbit
The gravitational force = centripetal force and this can be mathematically represented as
Where G is the universal gravitational constant with a value
M is the mass of the earth with a constant value of
r is the distance between earth and circular orbit where the rocke is found
Making r the subject
The orbital speed is represented mathematically as
Substituting value
The escape velocity is mathematically represented as
Substituting values
