Social scientists have argued about the importance of a multidimensional approach to the study of societal issues. from this perspective, researchers prefer to measure a construct with a multiple-item scale rather than a single-item scale. explain how you would measure satisfaction of the financial aid and scholarshipâs website at unr using a multiple-item scale (3 points). explain how you would measure satisfaction of the financial aid and scholarshipâs website at unr using a single-item scale (2 points). which one do you prefer to use? explain why one is better than the other.

The de broglie relation λ=h/p can be rewritten in terms of the wave number k as p=kâ. recall that wave number is defined by k=2Ï/λ. using the fact that λ=v/f, find the wave numbers k1 and k2 corresponding to frequencies f1 and f2. express your answer as two expressions

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
