Answer:
= 1000 hours
Explanation:
Earth's circumference is 10⁴ mile
speed of a sailboat is 10¹ mile/hour
distance = speed × time
10⁴ = 10¹ × t
t = 10⁴ / 10¹
t = 10³
= 1000 hours
Increase .... decrease .... presumably it's the "best shape" for a body which has been formed by the gravitational force

The correct answer is: wavelength =
4562 nm
Explanation:Rydberg's formula is given as:
--- (1)
Where
R = Rydberg's constant = 1.096 * 10^7 per meter
= 5
= 7
λ = Wavelength
Plug in the values in (1):
