7. i am making composites of silicone rubber and copper particles; by mixing thermally conductive particles into the thermally insulating rubber, i can increase the thermal conductivity of the mixture over that of the ‘neat’ rubber. the density of the rubber is 70 lbm/ft3 and the specific gravity of the copper is 9. if my composite is 15 mass percent copper, what is the composition on a volume basis?

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
