Answer:
Δx = 2m
Explanation:
From the given information:
De la información dada:
El desplazamiento ocurrió en un vector que se mueve desde una posición inicial particular hasta el final.
Entonces, supongamos que el desplazamiento es D;
Luego:
D = (7,5 ) - (5,7)
D = (2, -2)
Por lo tanto, el valor del desplazamiento de la coordenada x; Δx = 2m
Answer: For standardization purposes
Explanation:
As the question mentions, there were different types of measurements in the country for the same things so measuring a thing in one type of measurement and then comparing it to another was quite cumbersome.
It also made comparing units with the rest of the world difficult. To combat this the SI system was introduced. It gave an international standard for measuring different things based on the metric system. This allowed for worldwide standardization and comparison as things could now be measured in the same units.
Answer:
A. Electric potential energy into kinetic energy
Explanation:
The electric potential energy of the charged particles is converted into kinetic energy as the electron is released.

The average velocity of Sandy is given by the total distance covered S divided by the total time taken t:
The total distance covered is
while the total time taken is 2 hours + half an hour (for the rest) + 1 hour and half, so
Therefore, the average velocity is
