Refer to the diagram shown below.
The given data is
mass, kg Coordinates. m
------------- -----------------
2 (0, 0)
2 (2, 0)
4 (2, 1)
Total mass, M = 2+2+4 = 8kg
Let (x,y) be the coordinates of M.
Then, taking moments about the origin, we obtain
8x = 2*0 + 2*2 + 4*2 = 12
x = 1.5 m
8y = 2*0 + 2*0 + 4*1 = 4
y = 0.5 m
Answer: (1.5, 0.5) m
Answer: A herbivore.
Explanation:
A herbivore would be a top consumer in a food chain because they are primary consumers which leads you to secondary consumers who are carnivores to make sure they don't get to over populated and keep balance.
An object with a constant pushing or pulling force is exerted on it is greater than the frictional force, than A. The object will accelerate.
