Answer:
<h2>a = - 4.8</h2>Step-by-step explanation:
To find the value of a when b=6 we must first find the relationship between them.
The statement
a is inversely proportional to b is written as
where k is the constant of proportionality
When a = 7.2 , b = -4
So we have
k = 7.2 × - 4
k = - 28.8
So the formula for the variation is
When
b = 6
That's
We have the final answer as
<h3>a = - 4.8</h3>Hope this helps you
<h2>Answer:</h2>
is 3 ohms
In a circuit containing two resistors and
connected together in parallel, the total resistance
is given by;
---------(i)
<em>Make </em><em> subject of the formula;</em>
=>
=>
=> ---------------(ii)
From the question,
= 6Ω
= 2Ω
Substitute these values into equation (ii) as follows;
=>
= 3Ω
Therefore, the value of = 3 ohms or
= 3Ω
