Answer:
1.2 kg
Explanation:
Let UP ramp be the positive direction
F = ma
T - Wt || - Ff = m(0)
mg - Μgsinθ - μΜgcosθ = 0
m(9.8) - 13sin35 - 0.36(13)cos35 = 0
m = 13(sin35 + 0.36cos35) / 9.8
m = 1.15205... ≈ 1.2 kg
A.Positive as work=force×distance (assuming that distance is always a constant) the work will always be positive as the force is always positive(this is because force=mass×acceleration where the acceleration is always positive unless the mass is being slowed down)
A black sweater. Why? Because black is the most absorbent color while as white is reflecting the light. Hope this helps...
The appropriate response is tropics. Rainstorms happen when there is warm air that ascents. This air should likewise be clammy or saturated. Hence, regions that are warm and moist are typically where rainstorms happen. (These spots are most generally found around the equator)
