Cell wall and Chloroplast which are found in Plant cell but not in animal cell.
A) The calculated resistance needed to generate the current at low speed is; R = 480 ohms
B) Resistance at medium and larger speeds are;
At medium speed; R is less than that at low speed
At larger speed; R is less than that at medium speed.
A) We are given;
Voltage; V = 120 V
Current at lower speed; I = 0.25 A
Formula for resistance here is;
R = V/I
R = 120/0.25
R = 480 ohms
B) This means that if larger currents are required at higher speeds, it means that lower resistance would be required.
Similarly at medium currents the resistance will be lesser than that at lower speed but greater than that at larger speeds.

The tension on each segment of the clothesline is : 110 N
<u>Given data : </u>
mass of object = 100 n = 10 kg
Horizontal distance of clothesline = 4 m
middle of clothesline sag s by : 1m
<h3 /><h3>Determine the tension on each segment of clothesline</h3>
<u>First step</u> : calculate the horizontal angle made by the sagging
β = arctan ( 1 m / 2m ) ----- ( 1 )
= arctan ( 0.5 )
≈ 26.57°
Note : Tension in th y axis ( Ty ) = Tsinβ
Therefore :
Tension on each segment can be calculated using the formula below
2Tsinβ - mg = 0
solve for T
T = mg / 2sinβ
= ( 10 * 9.8 ) / 2 * sin 26.57°
= 98 / 0.89
= 110 N
Hence we can conclude that the tension on each segment of the clothesline is : 110 N

The Fifteenth reconstruction amendment (1869) was intended to protect freedmen against the injustices depicted in this cartoon.
In 1869, Congress passed a constitutional amendment guaranteeing black suffrage.
The Civil War Amendments, often known as the Reconstruction Amendments, are the Thirteenth, Fourteenth, and Fifteenth Amendments to the United States Constitution, which were ratified between 1865 and 1870.
The Thirteenth Amendment (1864) outlawed slavery and involuntary servitude.
The Fourteenth Amendment (1866) emphasizes citizenship rights and equal legal protection for all people.
The Fifteenth Amendment (1869) forbids discrimination in citizens' voting rights based on "race, color, or prior condition of servitude."
