Lab notes and DC motor

Lab notes Newton’s laws are based on principia which can be proved with Keplers orbits and projectile motion and electrodynamics particle and more motion and nuclear scattering force Dcmotor and speedometer 4.29 V 2.66 V I = 0.3 A, rint=(4.29-2.66)/0.3=5.43 ohms The voltmeter works based on a analog to digita converter Adc which works based on a digital to analog converter (Dac) and a successive approximation algorithm. The Dc motor when turned in reverse gives a voltage which can throw light on the speedometer thing . Resistance of motor winding 5.0 ohms which implies back emf \epsilon at that rpm= V-IR=2.66-0.3*5 = 1.16 V at an rpm of about 300 rpm Thus speedometer = dynamo + voltmeter <3 Let’s play with smartphone vibrator where if you press it vibrates as therapy did you know there’s heartbeat in settings? Thus speedometer = dynamo + analog voltmeter which works based on a coil spring and relativity based magnetic field force. The dynamo works in inverse law where force generates electricity just as inverse of 0.5 would be 2 I proved the faradays law long ago. I am right now at centrifugal force Phd let’s work on the cycle and forces to balance a friend of mine made. https://youtu.be/4UHLRmYNDMQ I am the best because I have principia . Best in all fields of science including biology and computer science and other fields It takes 2s period of oscillation for a 1 m cable to give g as 10 m/s2 A 40 W bulb had resistance v^2/2P= 600 ohms Del motor Note book Need to do quals prep again to stand for professorship. Digit binary representation Can make CcD thermo meter and shadow locate as part time
