A robin is flying around and its velocity vvv as a function of time ttt is given in the graph below where rightwards is the positive velocity direction. What is the robin's displacement \Delta xΔxdelta, x from t=0\,\text st=0st, equals, 0, start text, s, end text to 1.5\,\text s1.5s1, point, 5, start text, s, end text?

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.

Aregion of space in which a measurable gravitational force is indicated by the force exerted on a test mass is called
