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?

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

answer; how far out of place which the object finished relative to the starting location;
