The option that would be consistent through alternation of generations is that it exists as a diploid organism, and at other times as a haploid.
<h3>What is the alternation of generation?</h3>
This is the type of life cycle that is found in those plants and also algae which are known to have haploid and diploid stages.
The haploids usually grow to become a gametophyte.

It is important to note that the direct of flow of the electricity current in the Linear Machine is anti-clockwise direction. The resultant effect of this is such that is stand at variance with the change in flux as force is going the right direction. See attached Image (Illustration I).
<h3>What is the magnitude of the current?</h3>
Recall that Force (f) = il xB
Given that Force (F) = 10N; and
Magnetic Field Density B = 0.5T
Hence,
10 = i x 0.2 x 0.5
[Note that Width is converted to Meters from millimeters that is 200 mmm = 0.2m]
10 = 0.1i
i = 10/0.1
i = 100A
<h3>
What is the Induced Voltage Across the metal bar?</h3>
Note that Vg = Vde + IR
Vg = 10 + 100 x 0.05
Vg = 10 + 5
Vg = 15v
<h3>
What is the final speed of the metal bar?</h3>
The final speed of the bar is given as V
Recall that Induced Voltage is VB x L
That is:
15 = V x 0.5 x 0.2;
15 = 0.1 V
make V the subject of the formula:
V = 15/0.1
V = 150m/s
<h3>
What is the status of the Machine? a motor or generator?</h3>
Given that the current being supplied is in DC hence the machine is a generator. [Vdc x i]
<h3>What is the electric power of the source?</h3>
The electric power of the source is:
Vdc x i
= 10 x 100
= 1,000 watts

The expression which gives the same result as 4(-15) is
(-15) + (-15) + (-15) + (-15) .
According to the given question.
We have an expression 4(-15).
Since,
4(-15) = -60
Now, 4(-15) can be written as
(-15) + (-15) + (-15) + (-15)
And the value of the above expression
(-15) + (-15) + (-15) + (-15) = -60
Therefore,
4(-15) = (-15) + (-15) + (-15) + (-15)
Hence, the expression which gives the same result as 4(-15) is (-15) + (-15) + (-15) + (-15) .
