Calculate the magnetic field in a solenoid with 400 turns, a length of 0.03m and a current of 1.0A. What do you expect to have happen to the field if you double the current to 2.0A? 3. (2 pts) Calculate the period of the oscillation of a pendulum with a length=0.45m. 4. (2 pts) Calculate the magnitude of the induced emf in a 400-turn coil if the magnetic field inside the coil increases from 0T to 0.0200T (200g) over a time of 0.10s. Presume the area of the coil is 0.0004m 2 . If the induced emf in the first part was negative, what happens to the magnitude and the sign of the induced emf when the field is reduced from 0.0200T to 0T in 0.10s?

3. Start from: $D = -\frac{d(\ln q)}{dt} = D_i \left(\frac{q}{q_i}\right)^b$ to obtain: $G_{pD} = -\frac{q_i^b}{(1-b)D_i} \left[q_i^{1-b} - q_t^{1-b}\right]$ Please show all derivation steps. Describe a graphical method to analyze $q_t$ vs. $G_{pD}$ data based on the above equation. All symbols have usual meanings.

Texts: 9) Write a procedure named DisplayFirst20Factorials that displays the first 20 factorials in two columns. A factorial is defined as a function where F(N) is equal to N * F(N-1) where N > 0 and F(1) = 1. For example: 5! = F(5) = 5 * F(5-1) = 5 * F(4) = 5 * 4 * F(4-1) = 5 * 4 * F(3) = 5 * 4 * 3 * F(3-1) = 5 * 4 * 3 * F(2) = 5 * 4 * 3 * 2 * F(2-1) = 5 * 4 * 3 * 2 * F(1) = 5 * 4 * 3 * 2 * 1 = 120. Call the DisplayFirst20Factorials procedure from main. The output should look something like this: The white squares are where I cut out the numbers so you can't see the results. 10) Write a procedure named DisplayUserFactorial. The procedure should prompt the user to enter a number from 1 to 100. Continue to prompt the user until a number in that range is entered. Once a number in that range is entered, display the factorial. For example: The factorial of 5 is 120. Call the DisplayUserFactorial procedure from main.

7. 100% Sorting numbers is a very common problem; here, you just have 3 numbers to sort. This MIPS/SPIM program includes a subroutine called myadd that performs x=(y+z);. In the space below, replace the myadd subroutine with one named mysort that will sort the values of x, y, and z and into increasing order (i.e., make x the smallest and z the largest). (Hint: your code may take advantage of the fact that x, y, and z are consecutive words in memory.) You should test your routine using SPIM before you submit it, which will require merging it with a test framework like the one used in this MIPS/SPIM program but only submit the mysort routine here. #### # # Addition routine: # # x = y + z # .text .globl myadd myadd: la $t0, y # t0 = y lw $t0, 0($t0) la $t1, z # t1 = z lw $t1, 0($t1) addu $t2, $t0, $t1 #t2 = y + z la $t0, x # x = t2 sw $t2, 0($t0) jr $ra # return
