Answer:
C
Explanation:
the plant cools itself down by allowing water to evaporate from their leaves so it doesn't need water to cool down
To solve this problem we will make a graph that allows us to understand the components acting on the body. In this way we will have the centripetal Force and the Force by gravity generating a total component. If we take both forces and get the trigonometric ratio of the tangent we would have the angle is,


Dividing both.




Therefore the angle that should the curve be banked is 15.608°
Friction is causing the skateboard to stop rolling.
Answer:x=2 and x=3
Explanation:
Given
Potential Energy for a certain mass is

and we know force is given by


For Force to be zero F=0




Therefore at x=2 and x=3 Force on particle is zero.
