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:
#7 is D because you move the decimal 4 places
C
The elements are Lithium and Beryllium— just look at the mass number on the periodic table
Gas and liquid both take the shape of their container. The difference is gas molecules equally fills the space. Is there any more information?
