1-We have a lab-made voltmeter. It is made from a Galvanometer with a max current of 1000 JLA, a multiplier with a resistance of 199 ko. When the lab-made voltmeter shows 400 uA, our digital voltmeter displays the voltage 0,03' volt less than the actual value. If the digital voltmeter shows 8.03 volts, what is the internal resistance of Galvanometer?

Aparticle with mass 1.81×10−3 kg and a charge of 1.22×10−8 c has, at a given instant, a velocity v⃗ =(3.00×104m/s)j^. what are the magnitude and direction of the particle’s acceleration produced by a uniform magnetic field b⃗ =(1.63t)i^+(0.980t)j^?

The strong nuclear force acts over a small distance than the electrostatic force. true or false

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
