<h2>Weight of astronaut 2450 miles above the Earth is 80.38 pounds</h2>
Explanation:
Given that gravitational force, F, between an object and the Earth is inversely proportional to the square of the distance from the object and the center of the Earth.
Where F is gravitational force between an object and the Earth, r is the distance from the object and the center of the Earth and k is a constant.
Radius of Earth = 4000 miles
In case 1 an astronaut weighs 209 pounds on the surface of the Earth,
Now we need to find weight of astronaut 2450 miles above the Earth
r = 4000 + 2450 = 6450 miles
Weight of astronaut 2450 miles above the Earth is 80.38 pounds
Answer
given,
width of slit, d = 0.08 mm
d = 8 x 10⁻⁵ m
light of two wavelength
I₁= 446 nm
I₂ = 662 nm
a) angles at which the third dark fringe
m = 3 , I₁= 446 nm
C = 0.958°
m = 3 , I₁= 662 nm
C = 1.423°
b) angles at which the third dark fringe
m = 1 , I₁= 446 nm
C = 0.319°
m = 1 , I₁= 662 nm
C = 0.474°
