Carry out the following calculation and report the answer using the proper number of significant figures: 549.101 + 8.12 + 95.0076 - 651.9
a) 3.286
b) 0.3286
c) 0.33
d) 0.3
e) 1268.1

D) 0.3

Explanation:

Significant figure rules when adding and subtracting are that you keep the least number of decimals.

549.101 + 8.12 + 95.0076 - 651.9

=557.22 + 95.0076 - 651.9

=652.23 - 651.9

=0.3

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

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.
