A firefighter slides down a pole in a fire station with an acceleration of 6.2 m/s^2. Starting at rest he slides 3.7 m. What is his final speed. Time is not given help would be appreciated. I only need the equation as I already know the answer of 6.8 m/s.

Agalvanometer has an internal resistance of 100 ω and deflects full-scale at 2.00 ma. what size resistor should be added to the galvanometer to convert it to a milliammeter capable of reading up to 4.00 ma, and how should this resistor be connected to the galvanometer?

Idon’t quite understand this problem

Greg drew a diagram to compare two of the fundamental forces. which labels belong in the areas marked x, y and z? gravitational force electromagnetic force x. attractive y repulsive z: infinite range x: infinite range y attractive z. repulsive x. always attractive y: infinite range z: attractive or repulsive x. attractive or repulsive y infinite range z: always attractive
