hi can anyone help me with this question
Imagine that you have a green light bulb in a dark room will using a colored light appear to change the color of the objects in the room.
A. Yes the green items will appear white
B. yes blue and red items will look different
C. green is a primary color so it is neutral
D.no the brightness of the light determines the color
1. Yes, blue and red items will look different
2. It accentuates the bicycle
3. Hold up a clear glass of water
4. Black
5. All color in the light are absorbed except pink
6. Yes, the video is a completely different medium than the car parts
7. No, primary colors are used to make secondary colors
8. Black is not a color on the color spectrum
9. Blue
10. A shade is variations of one color, and a hue can be several colors
11. Installation
12. Hue
13. Add a little black to change the value
14. The combination of light and water creates a prismatic effect
15. Assemblage
(Try doing the lesson instead of cheating I need to learn that lesson as well)

of the objects in the room, not the color of the light bulb. Therefore, the answer is D.
A radio signal travels at 3.00 108 meters per second. How many seconds will it take for a radio signal to travel from a satellite to the surface of Earth if the satellite is orbiting at a height of 3.54 · 107 meters?
We can use the equation:
distance = rate x time
to solve for the time it takes for the radio signal to travel from the satellite to Earth's surface. Rearranging the equation, we get:
time = distance / rate
The distance in this case is the sum of the radius of the Earth (6,371,000 meters) and the height of the satellite (3.54 x 10^7 meters):
distance = 6,371,000 + 3.54 x 10^7 = 4.981 x 10^7 meters
The rate is the speed of light, which is 3.00 x 10^8 meters per second. Plugging in these values, we get:
time = 4.981 x 10^7 / (3.00 x 10^8) = 0.166 seconds (rounded to three significant figures)
Therefore, it would take approximately 0.166 seconds for a radio signal to travel from a satellite orbiting at a height of 3.54 x 10^7 meters to the surface of Earth.
Can I j get the math from that question no words
distance = 6,371,000 + 3.54 x 10^7 = 4.981 x 10^7 meters
rate = 3.00 x 10^8 meters per second
time = distance / rate
time = 4.981 x 10^7 / (3.00 x 10^8) = 0.166 seconds (rounded to three significant figures)
Thanks u have been really handy today
You're welcome! I'm glad I could help. Don't hesitate to ask if you have any more questions.
Is 4.981 x 10^7 over (3.00 x 10^8)
Is that what the / stands for
Yes, that is correct. In the expression "4.981 x 10^7 / (3.00 x 10^8)," the forward slash "/" is used to represent division. It means we are dividing 4.981 x 10^7 by 3.00 x 10^8 to find the time it takes for the radio signal to travel from the satellite to the surface of Earth.
To answer your question properly, we need to understand how colors work. Colors are defined by both the light that illuminates an object and the way our eyes perceive that light.
In this scenario, you have a green light bulb in a dark room. When the green light bulb emits light, it essentially floods the space with green-colored light. The objects in the room reflect some of this light and absorb the rest.
Answering the question now:
A. If the green items in the room reflect the green light, they would appear brighter or more illuminated, but they would not appear white. So, option A is incorrect.
B. If there are blue or red items in the room, they would largely absorb the green light rather than reflecting it. So, they would appear darker or less illuminated. This contrast between the green items appearing brighter and the blue/red items appearing darker can indeed make them look different. Hence, option B is correct.
C. Green is indeed one of the primary colors, along with red and blue. However, being a primary color does not make it neutral. In this scenario, the green light will predominantly affect the green items, making them appear brighter. So, option C is incorrect.
D. The brightness of the light does not determine the color. The color of light is determined by its wavelength. So, option D is incorrect.
Therefore, the correct answer is B – yes, blue and red items will look different in the room illuminated by a green light bulb.
