The selling rate of a radioactive isotope is decided by its activity. What will be the second-hand rate of a one month old 32P(t1/2​=14.3 days ) source if it was originally purchased for 800 rupees?

A flat circular coil of 200 turns of diameter 25cm is laid on a horizontal table and connected to a ballistic galvanometer. The complete circuit is having resistance of 800Ω. When the coil is quickly turned over, the spot of light swings to a maximum reading of 30 divisions. When a 0.1μF capacitor charged to 6V is discharged through the same ballistic galvanometer, a maximum reading of 20 divisions is obtained. Calculate the vertical component of the earth's magnetic induction.

Q.42. Figure 5.9 illustrates an aligned system consisting of three thin lenses. The system is located in air. Determine:(a) the position of the pointof convergence of a parallel ray incoming from the left after passing through the system;(b) the distance between the first lens and a point lying on the axis to the leftof the system, at which that point and its image are located symmetrically with respect to the lens system.

INSTRUCTIONS: YOU HAVE AN EXAMPLE OF DTMF signal synthesizing and analyzing to send a message as an audio waveform. In the provided example, A FILTER BANK approach has been utilized to find out the power for each frequency band, WHICH IS ESSENTIALLY A TIME-DOMAIN APPROACH. (The power of the signal's at the output of filters is found in the time domain). Run the code and try to understand the method. YOU ARE EXPECTED TO UTILIZE FREQUENCY DOMAIN APPROACH by taking Fourier Transforms of the audio signal and find power in the frequency bands which are described in Table 1 as follows. In MLX file, you should change some lines of code. DESCRIPTION OF FREQUENCY BANDS: Describe 10 frequency bands as follows. FOR LOW frequency bands, the center frequencies in COLUMN are given fi_Low=ID+50i. Say if the last TWO DIGITS of your ID number is 01, fLow=01+50*1=51. FOR HIGH frequency bands, the center frequencies in ROW are given. If your last digit of your ID is i, fi_HIGH=ID.ID.ID(i+2). For example, if ID = 1, f1_HGx = (1.1.1) * (i + 2) = 111 * (1 + 2) = 333. Table 1. Under this example, frequency bands should be as follows: LOW-FREQUENCY BANDS (in Hz): Band1 LO: 25-75 Band2_LO: 75-125 Band3_LO: 125-175 Band4_LO: 175-225 Band5_LO: 225-275 Band1_HI: 280-380 HIGH FREQUENCY BANDS (in Hz): Band2_HI: 388-499 Band3_HI: 499-610 Band4_HI: 610-721 Band5_HI: 721-832 ADD NOISE TO DTMF signal to test the performance of the algorithm under noisy signal conditions.
