Answer:
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. ... When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line.
Answer:
The astronaut will weigh 204.5N on the Moon
Explanation:
Weight, w = m*g
where;
m is the mass of the astronaut in kg
g is acceleration due to gravity ( g = 9.8 m/s² on Earth and 1.67 m/s² on the moon)
Given w = 1200N
m = w/g
m = 1200/9.8
m = 122.4489 kg
Thus, mass of the astronaut is 122.4489kg
weight of the astronaut on the moon = 122.4489*1.67 = 204.5N
Therefore, the astronaut will weigh 204.5N on the Moon
