Answer:
2nd answer 3.2m/s is a scalar l, all others are vectors.
Explanation:
In order to be considered as a vector a certain quantity must have both a magnitude and a direction.
The most common example is velocity. It has both magnitude and direction, like the 1st and the last answers.
The 3rd answer is an acceleration. It is also given with its direction. So we have to consider it also as a vector.
But 2nd answer has no direction mentioned, so it is considered as a scalar.
Coulomb's law explains the force between the charges whereas Newton's law of gravitation explains the force between the masses. ... The electrostatic force may be positive or negative in the case of Coulomb's law but the force is always negative in the case of Newton's law of gravitation
I believe that the statement is true. <span>Investigations allow for the control of variables. Changing variables will lead you to observations that may prove your hypothesis. Hope this answers the question. Have a nice day. Please feel free to ask more questions.</span>
