A scientific law is the simple mathematical expression of the relationship involved. A principle is the same relationship expressed in words. A theory is the explanation of the facts that make up the relationship.
The stress force that causes a mass of rock to pull or twist in opposite directions in called shearing. Shearing forces<span> are unaligned </span>forces<span> pushing one part of a body in one direction, and another part of the body in the opposite direction. Hope this answers the question.</span>
Answer:
A(3.56m)
Explanation:
We have a conservation of energy problem here as well. Potential energy is being converted into linear kinetic energy and rotational kinetic energy.
We are given ω= 4.27rad/s, so v = ωr, which is 6.832 m/s. Place your coordinate system at top of the hill so E initial is 0.
Ef= Ug+Klin+Krot= -mgh+1/2mv^2+1/2Iω^2
Since it is a solid uniform disk I= 1/2MR^2, so Krot will be 1/4Mv^2(r^2ω^2= v^2).
Ef= -mgh+3/4mv^2
Since Ef=Ei=0
Mgh=3/4mv^2
gh=3/4v^2
h=0.75v^2/g
plug in givens to get h= 3.57m
Answer:
Will load input interchange
Explanation:
The only thing that happens is the working position and the load input will interchange with each other. If the work output requirement changes with the hydraulic-press change. None of that destroyed.
B) the crust is much thinner from the other layers
