Question1
The input capacitance to an STM amplifier is 2pF. Desired frequency response is 5 kHz (such as 0.0002 s time constant). Select the largest current to voltage conversion resistor this constraint allows, and then compute the smallest measureable current (as in. just equal to the Johnson noise) at target bandwidth. The angular frequency, ω, at that is the response of an RC integrator falls by 3dB is given by ωRC=1
Question2
What opinion is answer for the monetary value of Gold with the density of 19.3g/cm^3 when it value is about $10 per gram. The Possible answers are 10^3, 10^6, 10^9 and 10^12. ^ represent an exponential power
Question3
You have a mass of 98 kg and are on a 55-degree slope hanging on to a cord with a breaking strength of 154 nektons. What should be coefficient of static friction to 2 decimal places between you and surface for you to be saved from the fire?
