What is the contour interval of this map? 50 100 400

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?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

The speed of light can be used to measure the
