<u>Answer</u>
1) A. 96 Candelas
2) A. Both of these types of lenses have the ability to produce upright images.
3) C. 5 meters
<u>Explanation</u>
Q1
The formula for calculation the luminous intensity is;
Luminous intensity = illuminance × square radius
Lv = Ev × r²
= 6 × 4²
= 6 × 16
= 96 Candelabra
Q2
For converging lenses, an upright image is formed when the object is between the lens and the principal focus while a diverging lens always forms and upright image.
A. Both of these types of lenses have the ability to produce upright images.
Q3
Luminous intensity = illuminance × square radius
square radius = Luminous intensity/ illuminance
r² = 100/4
= 25
r = √25
= 5 m
Answer: 2.34s
Explanation:
Given the following :
Horizontal Velocity(V) = 3.22m/s
Horizontal Distance = 7.54m
Therefore, the time spent in the air can be calculated thus:
Using the relation:
Speed = distance / time
3.22m/s = 7.54m / time
Time = 7.54m / 3.22m/s
Time = 2.34s
Answer:
Average velocity is the displacement of an object over time that also in a specified direction...

Answer:
I think it is eyeglasses
Explanation:
I think this because the glasses usually reflect the same thing sometimes and the light passes through really easy
Answer:
You just double the number of boxes it goes higher. Then triple the number for the second question. But don't change the time.
