PLEASE HELP DUE SOON 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:

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
