Answer:
Explanation:
Given that,
Small wheel applied force
F₁ = 50N
Small wheel radius
r₁ = 18cm
Bigger wheel radius.
r₂ = 29cm
Bigger wheel applied force
F₂ =?
Since the combination of those forces did not cause the wheel to rotate,
Then, Στ = 0
F₁•r₁ —F₂•r₂ =
50×18 — 29F₂ = 0
900 = 29F₂
F₂ = 900 / 29
F₂ = 31.03 N
The pulling force applied at the larger wheel is 31.03N
I had the SAME problem, put down Radiation and it’s thermal/light.
Energy is able to be transferred from one into another
Elements are identified by the nuclei of the atoms of which they are made. For example, an atom having six protons in its nucleus is carbon, and one having 26 protons is iron. ... Heavy elements can be formed from light ones by nuclear fusion reactions; these are nuclear reactions in which atomic nuclei merge together. This is how they are formed
