Answer:
If an object is electrically neutral it has no net charge becuase it has the same number of protons as it does electrons, which are opposite charges that offset each other. No, that just means that the sum of all its positive and negative amounts of charge equals zero.
Answer:
Value of 
Explanation:
We have given
In first case resistance is 
and current is 1.8 A
Let the potential difference is v
So 
----eqn 1
In second case resistance is 
and current is 1.6 A and potential difference will be as it is a series connection
So 
----eqn 2
From eqn 1 and eqn 2
Answer:
energia cinética
Explanation:
Passo um:
Dados fornecidos
Um bloco de peso igual a 10 N,
Constante de mola k = 50N / m
Passo dois:
A forma de energia formada é a energia cinética
Passo dois:
Da lei de Hooke, F = ke
e = F / k
e = 10/50
e = 0,2m
podemos resolver a energia cinética aplicando a fórmula
KE = 1 / 2ke ^ 2
KE = 0,5 * 50 * (0,2) ^ 2
KE = 0,5 * 50 * 0,04
KE = 1J
