Answer:large
Explanation:
As the temperature increases, materials with large coefficients of linear expansion increases a lot in size
A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.
I'll say that's mechanical weathering
a) since force = mass * acceleration
f= 900 * 0 (because constant speed = 0 acceleration)
similarly b) f = 0
I would say that this is the first law of thermodynamics.
