Suppose you are trying to lift a 3200 kg snuffleupagus with balloons. if each balloon has a volume of 150,000 cm^3. what is the minimum number of balloons you will need? the balloons have an average density of 0.245 kg/m^3 and assume a density of air of 1.20 kg/m^3?

Which best represents the law of conservation of mass ?

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?

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
