<span>So we want to know how can an object have three different weights at different times. So weight is Fg=m*g, where m is the mass of the objecct and g is the gravitational acceleration. On Earth, g=9.81 m/s^2, in space g is much less and on the moon g=1.625 m/s^2 So we see that the object changes its weight by moving it to space and on the Moon. </span>
I think you meant bending :).
Anyway when light enters a different medium the bending of light is refraction. Depending on the medium (i.e if it is denser or rarer) it will bend light closer or away from the normal ray (i.e a ray that hits the medium at 90 degrees does not bend).
Hope this helps :).
Answer:

The surface temperatures decreases with increasing distance from the sun. Venus is an exception because its dense atmosphere acts as a greenhouse and heats the surface to above the melting point of lead, about 880 degrees Fahrenheit (471 degrees Celsius).
Answer:
F = -3120 N
Explanation:
Lets write out everything we have:
Lineman:
m = 120kg
V1 = 6.5m/s
v2 = 0
t = 0.25
We should find acceleration, to move on to the next step;
a = v2-v1 / t
a = 0 - 6.5 / 0.25
a = -26m/s^2
Now we can use the Fnet formula and solve for F;
Fnet = ma
fnet = (120)(-26)
F = -3120 N
