Answer:
A. A line can be drawn from the planet to the sun that sweeps out equal areas in equal times
Explanation:
This is exactly what Kepler's second law of planetary motion states:
"the segment joining the sun with the center of each planet sweeps out equal areas in equal time"
This law basically tells how the speed of a planet orbiting the sun changes during its revolution. In fact, we have that:
- when a planet is closer to the Sun, it will orbit faster
- when a planet is farther from the Sun, it will orbit slower

Answer:
0.000003782 m
0.000001891 m
0.000001197125 m
Explanation:
= Wavelength = 248 nm
D = Diameter of beam = 1 cm
f = Focal length = 0.625 cm
The angle is given by
The width is given by
The required width is 0.000003782 m
Minimum resolvable line separation is given by
The minimum resolvable line separation between adjacent lines is 0.000001891 m
when 
The new minimum resolvable line separation between adjacent lines is
