Aman walked back and forth in a straight line. if he travels from point a to point b, then turns around and stops at point c, what is his total displacement after 2 minutes? a. 150 b. 350 c. 100 d.50

The answer is D.50

Hope i helped

Answer : The total displacement after 2 minutes is 50 m.

Solution :

Displacement : It is defined as the change in the position of an object. It is a vector quantity that means it has direction as well as magnitude.

In mathematical term, it is defined as,

By using this formula, we get the total displacement after 2 minutes.

Initial position, A = 0 m

Final position, C = 50 m

Now put the given values in above formula, we get

Therefore, the total displacement after 2 minutes is 50 m.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
