Use the redlich-kwong equation to plot the compressibility factor, z, against p for methane for t 180 k, 189 k, 190 k, 200 k, and 250 k. hint: calculate z as a function of v and p as a function of v, and then plot z versus p.

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

c) up is the direction the magnetic force is acting on the charge.

it is a negative acceleration

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
