The "parallel plate" field plate used in this lab has two parallel conductors separated by (6.70 ± 0.05) cm. If the electric potential difference between the two parallel plates is (8.0 ± 0.5) v, what is the magnitude of the electric field between the plates with an error estimate. Present the answer in appropriate significant figures, as well as proper error propagation / estimates.

What should the power status of a circuit be when measuring resistance with an ohmmeter?

In which situation has the independent variable for the experiment been changed? check all that apply. changed from counting the number of duckweed at day 0 and day 14 to counting them every day changed from testing duckweed growth in beakers to testing duckweed growth in large outdoor tanks changed from testing the effect of ph on duckweed growth to testing the effect of light levels on duckweed growth changed from testing the effect of acid ph on duckweed growth to testing the effect of basic ph on duckweed growth

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
