6. When two oceanic plate boundaries meet, what crustalfeature forms(see photo below)
A Plate Tectonics
B. Sea Floor Spreading
C. Folded Mountains
D. Volcanic Island Arc

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.

answerspecific gravity;

the objects have the same charge.
