Answer:
<em>The current is 1 A</em>
Explanation:
<u>Current in a Series Connection </u>
When two or more elements are connected in series, all of them have the same current, and the sum of their individual voltages is the total voltage applied to the circuit.
According to Ohm's law:
V=R.I
Where V is the voltage, R is the resistance and I is the current of a circuit.
We have a voltage of V=1.5 V + 1.5 V = 3 V and a resistance of R=3 ohms.
We can calculate the current by solving for I:
The current is 1 A
Answer:
<h2> The answer is </h2><h2>a. 5g/mL</h2>Explanation:
Given data
mass m= 45g
volume v= 9mL
we know that density=m/v
substituting our given data we have
What is Density?
The Density of a body can be defined as the ratio of mass to volume,
or
Density, mass of a unit volume of a material substance. The formula for density is ,
where d is density,
M is mass, and
V is volume.
Density is commonly expressed in units of grams per cubic centimetre.
