UGH NO ONE IS HELPING MEEE Think and discuss : Why doesn't the steepness of a frictionless ramp affect the velocity of the block at bottom of the ramp? (Hint: Discuss conservation of energy in your answer .)

Because energy is conserved, the kinetic energy of a block at the bottom of a frictionless ramp is equal to the gravitational potential energy of the block at the top of the ramp. This value is proportional to the square of the block’s velocity at the bottom of the ramp. Therefore, the block’s final velocity depends on the height of the ramp but not the steepness

of the ramp

Explanation:

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.

if you're asking what comes out, it's steam.
