You create a plot of voltage (in v) vs. time (in s) for an rc circuit as the capacitor is charging, where v=v_{0} \cdot \left(1- e^{ \frac{-\left(t\right)}{rc} } \right). you curve fit the data using the inverse exponent function y=a \cdot \left(1- e^{-\left(cx\right)} \right)+b and loggerpro gives the following values for a, b, and c. a = 4.211 ± 0.4211 b = 0.1699 ± 0.007211 c = 1.901 ± 0.2051 what is the time constant for and its uncertainty?

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j

The speed of light can be used to measure the

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
