Answer:
the answer is c
Explanation:
by transferring heat from the tropics to the colder climates
Answer:
B
Explanation:
the river is caused by weathering and erosion is the breaking down of rocks
Fk= mgcostheta * coefficient of friction
Fk= (.05kg)(9.80)(cos30)(.20)=.085 N
change in thermal energy= Fk* distance covered up slope (d)
change in thermal energy = .085 * d
the final height so y=dsin30
Kf + Uf + change in thermal energy = Ki + Ui
(.05kg)(9.80)(dsin30) + (.085d) = (.5)(25 N/m)(.1m)^2
d= .379 m = 37.9 cm
