. You have 2 metal samples as shown above. Find the volume for each of the metals in the correct number of SIG FIGS and designate the metal that has the greatest volume.

3 hours because it is a decent distance.

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.

b is the correct answer

mark me brainliest and hope this
