1) B.Metallic windows
2) D. Absorption
3) A. Clear glass
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 distance of the object from the mirror is 3cm.
To calculate the distance of the object from the mirror, we make use of the mirror formula
<h3>Mirror formula</h3>
- 1/f = (1/u)+(1/v)............ Equation 1
Where:
- f = Focal length of the mirror
- v = image distance
- u = object distance.
Using the real is positive convention,
Given:
Substitute these values into equation 1 and solve for u
- 1/5 = (-1/10)+(1/u)
- 1/5+(1/10) = 1/u
- 1/u = (2+1)/10
- 1/u = 3/10
- u = 10/3
- u = 3.33
- u = 3 cm
Hence, The distance of the object from the mirror is 3cm.

Answer:
According to Castro, the territory of Latin America is suffering from countries like the United States using their imperialistic powers. According to Castro, countries such as the United States take advantage of Latin American countries. Kennedy and other US leaders believe that Castro has created a dictatorship. The people of Cuba are suffering because Castro and communism oppress people politically and economically.
