Answer: 69.8 degree
Explanation:
F*cos(theta)
is your pushing force projected along the x axis and
-F*0.368*sin(theta)
is the friction force generated by the pressure downwards
when F cos(theta) = F*0.368*sin(theta)
the box wont move no matter how large F is, because you are adding no net force along the x-axis
so sin(theta)/cos(theta) = 1/0.368
tan^-1(1/0.368) = theta
theta = 69.8 degrees
Answer:
The two major sources of energy for the rock cycle are also shown; the sun provides energy for surface processes such as weathering, erosion, and transport, and the Earth's internal heat provides energy for processes like melting, and metamorphism
In gasoline powered boats, it is important to keep in mind the proper procedures in handling before activating the engine or your boat. Such as activating the blower.
