Hey there!
Okay so, the Lithosphere is made out of Earth’s outermost layer, which is composed of rocks in the crust and the upper mantle that behave as brittle solids.
The Mantle is made up of rock containing silicon, iron, magnesium, aluminum, oxygen and other minerals.
The Core has two parts. The solid inner core made up of iron. The outer core is surrounded by a liquid composed of a nickel-iron alloy.
I hope this helps!
We can solve the problem by requiring the equilibrium of the forces and the equilibrium of torques.
1) Equilibrium of forces:
where
is the weight of the person
is the weight of the scaffold
Re-arranging, we can write the equation as
(1)
2) Equilibrium of torques:
where 3 m and 2 m are the distances of the forces from the center of mass of the scaffold.
Using
and replacing T1 with (1), we find
from which we find
And then, substituting T2 into (1), we find
Answer:
here
Explanation:
There are two forces acting upon the skydiver - gravity (down) and air resistance (up). The force of gravity has a magnitude of m•g = (72 kg) •(9.8 m/s/s) = 706 N. ... a 3.25-kg object rightward with a constant acceleration of 1.20 m/s/s if the force of ... of 33.8 kg, how far (in meters) will it move in 1.31 seconds, starting from rest?
