Em muitas situações do dia a dia, temos que solucionar questões que exigem conhecimento das relações existentes entre as grandez
1 answer:
Answer:
Explanation:
1) Olá, vamos calcular primeiramente o Volume da Piscina. Ela é uma piscina com uma forma tradicional, retangular. Temos a largura, o comprimento e a profundidade.
2) Precisamos fazer uma correlação entre a medida de capacidade (litro) e de volume, já que o custo é por litro d'água.
3) Observe que Francisco gasta 0,005 g de por semana.
Considerando que o mês tenha 4,5 semanas. E que quanto mais se trata a piscina mais se gasta Hipoclorito de Sódio. Temos uma relação diretamente proporcional.
Finalmente,
3.1) Rendimento do hipoclorito de produto em gramas por semana:
3.2) Consumo mensal (y), considerando 4,5 semanas:
3.3) O custo da manutenção, já que 18 kg de custa R$ 135 e são grandezas diretamente proporcionais:

Answer:
- Current = 0.33 A
Explanation:
- For diagram refer the attachment.
It is given that five cells of 2V are connected in series, so total voltage of the battery:
Three resistor of 5, 10
, 15
are connected in Series, so the net resistance:
According to ohm's law:
On substituting resultant voltage (V) as 10 V and resultant resistant, as 30 we get:
The electric current passing through the above circuit when the key is closed will be <u>0.33 A</u>
Answer:
hello your question is incomplete attached below is missing part of the question
answer:
1 ) Magnetic field due to long current carrying wire :
Therefore the net magnetic field due the both wires ; B = B + B
. when we adjust the current I
= I
then the Netfield (B ) = zero
2) The distance between the field lines are not equally spaced and this is because the separation between field lines increases with the increase in the distance between the wires
3) Increase in current through the wire will lead to increase in force and this can be explained via this equation
