Answer:
<em>The force is W</em>
Explanation:
<u>Sum of Electrostatic Forces</u>
The electrostatic forces have magnitude and direction as all physical forces do. Two point charges repel each other if their charges have the same sign, and they attract each other if their signs are opposite.
The bottom two charges and the top charges are negative, thus all the forces are repulsive. Charge 1 exerts a force F1, charge 2 exerts a force F2. Please look at the diagram in the figure below. The sum of both forces is shown with a red line. The horizontal component of the forces cancel each other, thus the total force goes upward.
The correct vector that best represents the net force is W
Vê quantidade de movimento precisa ta em kg.m/s certo?
a questão disse que a gravidade é de 10 int posso dizer q minha massa é de 36kg pois p(360n)= massa . gravidade(10).
ja a velocidade esta km/h int vou dividir por 60 por 3,6 ou 600 por 36, aumentando de 10 vezes pra poder ajudar no calculo.
quantidade de movimento é Q= m(36) . velocidade( 600/36)
Q= 36.600/36 se corta 36 de cima com o 36 de baixo vai ficar 600kg . m/s
Answer:
D. A record of all the physical activity you complete in one week.
Explanation:
A "Fitness Log" allows you to keep track of your workout or exercise. Therefore, it is <em><u>a record of the different workout you've managed to complete within a time frame</u></em>. It gives you several information such as the<em> type of workout you've completed, its duration and the time of the day it was performed</em>. This makes a person motivated to exercise because he can see his progress. He may also include <em>his mood before and after workout</em> in order to become more mindful in exercising and many other things.
