Atest charge of -1.4 × 10-7 coulombs experiences a force of 5.4 × 10-1 newtons. calculate the magnitude of the electric field created by the negative test charge.

a. 1.4 × 106 newtons/coulomb
b. 1.9 × 106 newtons/coulomb
c. 5.4 × 10-1 newtons/coulomb
d. 3.6 × 106 newtons/coulomb

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
