The mean free path of identical molecules is given by: $l = \frac{k_B T}{\sqrt{2 \pi P d_m^2}}$ Where $k_B$ is the Boltzman constant ($1.38 \times 10^{-23}$ J/K), P is the pressure, $d_m$ is the molecular diameter, T is the temperature. Calculate the mean free path (in meter) for nitrogen molecules at 300K and pressure of $10^{-5}$mbar. Use a value of molecular diameter of ($3.80 \times 10^{-10}$ m). Please remember to put all input values to SI units before calculating l Part(b) The pressure is now reduced from $1\times10^{-5}$ to $1\times10^{-7}$ mbar. The mean free path will therefore: Select one: Increase by a factor of $10^4$ Decrease by a factor of 10 Decrease by a factor of 100 Increase by a factor of 10 Stay the same Increase by a factor of 100

Title: Digital Circuit Analysis and 7-Segment Display Connection Time Slot: 9:00 am - 2:00 pm, 12:00 pm - 3:00 pm, Monday to Friday 2:59 pm - 5:59 pm, 5:39 pm - 8:30 pm Please attempt all problems below. Half of your grade for this assignment will be based on your performance. Consider the digital circuit below: a) Record the predicted output of the circuit for the inputs provided by each row of Table 1. In the table, "T" is equal to one period of the clock signal (Tc) and the arrow symbol (→) indicates a rising edge of the clock. Table 1: | Time (Tc) | CE | Q1 | TQ0 | ST | |-----------|----|----|-----|----| | 0 | 0 | 0 | 0 | 0 | | 1 | 1 | 0 | 1 | 0 | | 2 | 1 | 1 | 1 | 0 | | 3 | 0 | 1 | 0 | 1 | | 4 | 1 | 0 | 0 | 1 | | 5 | 0 | 0 | 1 | 1 | | 6 | 1 | 1 | 1 | 1 | | 7 | 0 | 1 | 0 | 0 | b) We now connect the output bus (Q) to a common Anode 7-segment display. Please shade each 7-segment display at each time interval in Table 2. Table 2: | Time (s) | 7-Seg Connected | |----------|-----------------| | 0 | 0 | | 3T | 0 | | 6T | 0 | | 7T | 0 |
