Answer:
The area of the portion of the wall that will be painted is 105 square feet
Explanation:
Total area of wall = 12 × 10 = 120 ft²
The area of the wall that will not be painted = area of the blackboard = 5 × 3 = 15 ft²
So, the area of the wall to be painted = Total area of wall - Area of the wall that will not be painted = 120 - 15 = 105 ft²
Answer:
The converging lenses make the eyes appear larger, and the diverging lenses make the eyes appear smaller.
Explanation:
Diverging lenses are placed in the path of a beam of parallel rays that allow the rays to diverge after refraction.
Glasses use diverging lenses to correct for nearsightedness a diverging lens will diverge light before it reaches the eye.
Farsightedness refers to the inability to see close objects for which a converging lens is required to increase power.
In the given situation,
<u>the converging lenses make the eyes appear larger, and the diverging lenses make the eyes appear smaller</u>

Answer:
1.6 s
Explanation:
To find the time in which the potential difference of the inductor reaches 24V you use the following formula:
V_o: initial voltage = 60V
R: resistance = 24-Ω
L: inductance = 42H
V_L: final voltage = 24 V
You first use properties of the logarithms to get time t, next, replace the values of the parameter:
hence, after 1.6s the inductor will have a potential difference of 24V
