Consider long polystyrene chains in carbon disulphide (athermal solvent). Estimate the correlation length ξ and tube diameter a at vol- ume fractions φ = 0.1 and φ = 0.02. (ii) Consider long polystyrene chains in cyclohexane at 35 ◦C (θ−solvent). Estimate the correlation length ξ and tube diameter a at volume frac- tions φ = 0.1 and φ = 0.02.

What is the measure of a change in an objects velocity?

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
