A new band sensation is playing a concert and recording it for a live album to be released this summer. Select all the statements that are true for when the microphone records the sound. The microphone changes the wave from mechanical wave to an electromagnetic wave. The recorded waves are electromagnetic waves. The microphone does not change the wave type. The recorded waves are mechanical waves. The frequency or amplitude of the waves will not change in the microphone. The frequency or amplitude of the waves will change in the microphone. ✓ The microphone changes the wave from an electromagnetic wave to a mechanical wave. >

This questions from electronics two course

Write the answers precisely, do not elaborate unnecessarily, and don't use chatgpt, if i caught it I'm gonna downvote Question: Discuss the electrochemical techniques that are useful to study the capacitive properties of a material. Highlight the importance of each technique

I need the answer as soon as possible

2. Using the IV plots shown in Fig. 3 (and found in the reintroduction to PSpice) design a BJT biasing circuit that results in the following parameters: VCE = 2 Vand ig = 40 μA. We also require the power supply to be fixed at 5 Volts (this is where the load line intercepts the iB =ic = 0 line). You may use the circuit shown in Example 1. Note that all resistor values in Example 1 must be recalculated. Your solution for the base to ground and base to collector resistors may not be unique.

You have an unfair six-sided die, where the probabilities of rolling each number are asfollows:P(1) = 0.1, P(2) = 0.2, P(3) = 0.3, P(4) = 0.15, P(5) = 0.1, P(6) = 0.15Calculate the mean and variance of this die
