To calculate the strength of the eye lens, we use the formula
( thin lens formula)
Here, u is the object distance and v is image distance.
Given, and
Therefore,
Thus, strength of the eye lens is
1cathode rays plural : the high-speed electrons emitted in a stream from the heated cathode of a vacuum tube
2: a stream of electrons emitted from the cathode of a vacuum tube —usually used in plural

Answer:
This was my best estimation of the answers
Answer:
15000000 m
Explanation:
From the question,
Speed (S) = Distance(d)/Time(t)
S = d/t....................... Equation 1
Make d the subject of the equation
d = St..................... Equation 2
Given: S = 50 km/s = 50000 m/s, t = 5 minutes = 5*60 seconds = 300 seconds
Substitute these values into equation 2
d = 50000(300)
d = 15000000 m
Hence the skier travels 15000000 m
