2. three students derive the following equations in which v refers to the speed(m/s), a, the
acceleration (m/s), t the time, and the subscript zero (0) means a quantity at time t = 0.
here are their equations: (a) v = v. + 2at, (b) v = v, + 1/2 ata and (c) v= vo + at. which on
these could possibly be correct according to a dimensional check, and why?

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
