A white blood cell has a diameter of approximately 12 micrometers or 0.012 um a model represents its diameter as 24 um what rati
1 answer:
Answer:
The ratio of the model size is 1 : 2000
Explanation:
Given
Real Diameter = 0.012 um
Scale Diameter = 24 um
Required
Determine the scale ratio
The scale ratio is calculated as follows;
Substitute values for real and scale measurements
Divide the numerator and the denominator by 0012um
Represent as ratio
<em>Hence, the ratio of the model size is 1 : 2000</em>

Answer:
When they are connected in series
The 50 W bulb glow more than the 100 W bulb
Explanation:
From the question we are told that
The power rating of the first bulb is
The power rating of the second bulb is
Generally the power rating of the first bulb is mathematically represented as
Where is the normal household voltage which is constant for both bulbs
So
substituting values
Thus the resistance of the second bulb would be evaluated as
From the above calculation we see that
This power rating of the first bulb can also be represented mathematically as
This power rating of the first bulb can also be represented mathematically as
Now given that they are connected in series which implies that the same current flow through them so
This means that
So when they are connected in series
This means that the 50 W bulb glows more than the 100 \ W bulb
Total resistance=R1+ R2= 6Ω
Voltage=12v
Current =
Current= 2A
In a series circuit, equal current passes through every resistance.
Answer is option A
Voltage=12v
Current =
Current= 2A
In a series circuit, equal current passes through every resistance.
Answer is option A
