Where did most of the comets in the kuiper belt come from?

a. they came from the oort cloud
b. they are the remains of a planet after it exploded
c. they are the remnants of the inner planet's accretion
d. they are the remnants of the outer planet's accretion

D. They are the remnants of the outer planet's accretion

Explanation:

Comets are small irregular shaped and sized icy bodies found in Kuiper belt and Oort cloud. These are the primordial debris. The comets are the remnants of the outer planets accretion disk. These are composed of rocks, dust, ice and frozen gases. The comets present in Kuiper belt are short period comets. Comets revolve around the sun in elliptical orbit.

it is called kinetic energy

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
