Answer:
20 m
Explanation:
mechanical adv = distance over which the effort is applied (de) / distance the load travels (dr)
MA = de/ dr
10 = de/ 2
de = 20 m
Kinetic energy is energy in motion and potential energy is stored energy
Are there any options??
I would have to say metal of course but without options I can't assume anything
Archimedes principle states
that
F1 / A1 = F2 / A2
F2 = (A2 / A1) * F1
Also, formula for the force is
F = mg. Formula for the area of the cylinder is A = πr^2, therefore we get
F2 = (πr2^2 / πr1^2) * mg
Since the diameter of the
cylinders are 2 cm and 24 cm, r1 = 12 and r2 = 1.
Substituting the values to the
derived equation, we get
F2 = (π 1^2 / π 12^2) * 2400 * 9.8
F2 = 163.3333 N
