889.9 is written as

In this examples, 5000 and 889.9 are written in the standard notation and  and  are written in the scientific notation.

As we are given that the measurement of mass in standard notation. Now we have to convert it into scientific notation.

Given standard notation : 0.0000064 g

The scientific notation will be,

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
