the chart below compares the characteristics of four objects discovered in the solar system. which of these objects is most like

olga_2 [115]

Answer:

I would go with B

Explanation:

first of all,planets don´t exist in Kuiper belt because that is where dwarfs go

second,a planet is not a moon of another object,there is no such thing as that

third,planets do have enough gravity to keep other objects far away from its orbit.

fourth,a planet does orbit around the sun

fifth,planets do have a long orbit

sixth,a planet is also almost in a circular shape

B was the most likely to be a planet because one of the characteristics were wrong,unlike the others,I also hope this helps and hope that its the right answer,I'm actually not too sure,sorry if I got it wrong.

Calculate the force needed to accelerate a baseball with a mass of 0.45

RideAnS [48]

Mass=0.45kg
Acceleration=175m/s^2

$\\ \bull\tt\dashrightarrow F=ma$

$\\ \bull\tt\dashrightarrow F=0.45(175)$

$\\ \bull\tt\dashrightarrow F=78.75N$

$\\ \bull\tt\dashrightarrow F=78.8N$
