How does gravity depend on the mass of the two objects?
O
A. Gravity decreases as the mass of the larger object increases,
O
B. Gravity increases with the product of the mass and the distance,
O
C. Gravity increases os the mass of either object increases
D. Gravity decreases as the mass of the smaller object increases

1.solid

2.carbon dioxide

3.helium

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
