The more slanted the sun's rays are, the longer they travel through the atmosphere, becoming more scattered and diffuse. In the winter, Earth tilts away from the Sun.
C) refract
Explanation:
When light passes from air into water, the light waves will bend or they refract and the pencil will appear to be broken.
In normal space, light travels along a straight path with no alteration of the path along which it travels.
- When light crosses the boundary from a denser to a less dense medium, it is refracted.
- Refraction implies that the angle of the light is bent.
- This is because the new medium causes the light rays to slow down compared to the speed it was coming forth with.

<span>I think the average velocity b/w t =a and t= b would be
Avg vel. = change in vel./ change in time</span>
Answer:
gravity is vital because as we know space curves around objects like planets, in this curvature is our atmosphere and a gravitational pull holding everything in, without this curvature we would not have any gravitational pull.
Hope it helps!!!
Explanation:
Answer:
speed of the arrow as it leaves is 41.05 m/sec
Explanation:
We have given mass m = 0.285 kg
Average force F = 182 N
Distance traveled d = 1.32 m
We know that work done = force distance
Sp work done =
Now according to work energy theorem work done will be equal to kinetic energy
So
v = 41.05 m/sec
So speed of the arrow as it leaves is 41.05 m/sec
