Expert Answer:

1.Henry Per Meter (H/m) is the unit commonly used in the SI unit system.


The original unit for measuring the amount of radioactivity was the curie (Ci)–first defined to correspond to one gram of radium-226 and more recently defined as:

1 curie = 3.7x1010 radioactive decays per second [exactly].

In the International System of Units (SI) the curie has been replaced by the becquerel (Bq), where

1 becquerel = 1 radioactive decay per second = 2.703x10-11 Ci.

3.1 kilowatt hour = 3.6 × 106 J


5.(4) They change with change of conditions
