The force of attraction will decrease when objects move apart
use a = (v1-v2)/t so u would put 14 (initial velocity or v 1) - 6 (the v2) and divide all of that by 4 seconds to get 2m/s/s as your acceleration

True
Explanation:
A base is a substance that is often used as the chemical opposite of an acid.
Both behaves in opposite way to one another.
They can be said to complementary or conjugate chemicals.
- According to Bronsted-Lowry theory, an acid is a proton donor and a base is a proton acceptor.
- The lewis theory states that an acid is an electron pair acceptor while a base is an electron pair donor.
- Acids turn blue litmus paper red and bases turns red litmus paper blue.
