Why do two flashlight have different brightness
1. Why do two flashlight have different brightness
Answer:
There are many factors as to what have prompted the two flashlights to emit different brightness of light or commonly known as luminosity. First reason could be that the batteries inside the two flashlights have now different capacities, which means the other one is nearing its end of life.

4. how does the brightness of the bulb compare with eachother with two dry cells with two flashlight bulbs
Answer:A bulb connected to two cells in series is brighter than connected two to cells in parallel. Compare the brightness of the bulb produced by two cells in parallel with one cell. A bulb connected by two cells in parallel is equally bright as when connected to one cell.I'M NOT SURE, I HOPE OT CAN HELP
5. 1.Why Lights cant travel Though the walls?2.if you turned on a Flashlight Did the place where you turned on the flashlight become bright right away? why?3.if you Turned on a Flashlight , Did the room lit? why?(Thank you)
Answer:
1. On the other side, light waves are very very small waves, their size ( wavelength ) is comparable to the size of atoms in the wall. And that is why they are not able to go through the wall.
2. When the switch of a flashlight is pushed into the ON position, it makes contact between two contact strips, which begin a flow of electricity, powered from the battery. The batteries are connected in such a way that electricity (flow of electrons) runs between the positive and negative electrodes of the battery.
3. Yes, Because that light is shining onto a very rough surface. If it was shone onto a highly polished surface, such as a mirror, you will see something like a point of light- the reflection of light directly from your flashlight to your eyes. When shone on a mirror, all or most parts of the mirror will reflect light, but the light will be reflected in a single direction at each location on the mirror based on the angle of the incoming light (most of which will not be reflected back at your eyes). The image you posted describes what happens very well in the case where the labeled wall is a mirror.
6. AS THE FLASHLIGHT IS MOVED AWAY FROM YOUR FACE DOES THE LIGHT COMING OFF IT OR REALLY CHANGE IN BRIGHTNESS?
Answer:
The intensity or brightness of light as a function of the distance from the light source follows an inverse square relationship. ... Notice that as the distance increases, the light must spread out over a larger surface and the surface brightness decreases in accordance with a "one over r squared" relationship.
Answer:
yes it change brightness so its called lowed light

11. how will you increase the brightness emitted by a flashlight
In cellphone? Because some Iphone users had a setting that you can adjust. You can press auto brightness
12. why do star have different brightness?
Because some stars are bigger some are smaller than others.
13. suppose you have two rechargeable batteries. one is fully charged and the other one is almost empty. you inserted each battery in each of the two flashlights. predict what will happen to the light emitted in the two flashlights
Answer:
The flashlight with full battery will emit more light while the flashlight with the battery of almost empty will emit weaker light.
14. The street lights are all equally bright. Why do they appear different?
Answer:
A star's brightness also depends on its proximity to us. The more distant an object is, the dimmer it appears. Therefore, if two stars have the same level of brightness, but one is farther away, the closer star will appear brighter than the more distant star - even though they are equally bright.
Explanation:
15. If a bright flashlight has a light intensity of 15.0 candela at a distance 1.00 m from the lens, what is the intensity of the flashlight 100.0 m from the lens?
light intensity is 1,500 candela at a distance of 100.0 m
16. What does the color of a star mean? Why do stars differ in brightness? plsss po
Answer:
the color of a star indicates its temperature,stars really differ in their brightness because it depends on its proximity to us. The more distant an object is, the dimmer it appears.

20. Questions: 1. What are the differences between the series and parallel circuits you have made? 2. What happens to the brightness of the bulb on Set-up C as you remove one battery at a time? Why do you think so? 3. What happens to the brightness of the remaining bulb/s on Set-up D as you remove one bulb at a time? Why do you think so?answer it now
Answer:
In a series circuit, all components are connected end-to-end, forming a single path for current flow. In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points.The brightness will get reduced because the total resistance of the bulbs will increase and their current will decrease.Since current multiplied by voltage equals power (I x V = P , directly related to the light output), and the voltage in this case remains the same, the total power gets reduced, and the total light output (and brightness) gets reduced as well.The bulbs in the series will NOT GLOW if you remove one bulb from it (if you expect a detailed answer please read the following explanation)Reason
Imagine a series connection with 3 bulbs. As it's series connection, the negative terminal of bulb 1 is connected to positive terminal of the bulb 2, then the negative terminal of bulb 2 is connected to positive terminal of bulb 3.
As we remove one bulb (For example bulb 2) it removes electrical connection between bulhb 1 and 3. hence circuit will not be complete.
Hence none of the bulbs in series will glow.
In simple terms when we remove a single bulb from a series, No Bulb Glows

21. Have you known bright people who are not wise? Why do you think so? Make two lists, one containing the characteristics of intelligent people, the other the characteristics of wise people. Compare the similarities and differences in your lists. What kind of wisdom would you like to possess?
Similarities and differences in characteristics between intelligent and wise people.
Intelligence is usually measured by IQ, however this is not always the case. How a person behaves can also become a parameter in deciding whether that person is intelligent or not. This also applies to whether a person is wise or not. A wise person is judged based on his behavior, attitude, and most probably what they talk about.
The similarities and differences between the two include:How both are often calm and are not in rush.An intelligent and wise person would not jump into a conclusion easily.They respect people.An intelligent person probably behaves based on his logic, while a wise person based on his feelings.Intelligent people prioritize benefits upon everyone, while a wise person prioritizes other people's feelings.That's it. Now, I hope that you do notice the similarities and differences between an intelligent and a wise person.

23. why do most flowers have bright colored petals?
Answer:
Flower petals are colorful because the color attracts birds, bees and other insects. The insects land in the flower and spread pollen, which helps fertilize the flowers and create seeds
Answer:
Flower petals are colorful because the color attracts birds, bees and other insects. The insects land in the flower and spread pollen, which helps fertilize the flowers and create seeds. Some flowers change color as they grow older. This color change is a signal to insects that the flowers are past their prime.

27. why do some insects have bright colors and sharp patterns?
Explanation:
Some insects have bright colours to attract one another to mate. Others, such as the ladybird, advertise the fact that they taste nasty by being colourful. Birds and other predators soon learn to associate bright colours and bold patterns with creatures that taste nasty or that might be poisonous.
Answer:
The function of aposematism is to prevent attack, by warning potential predators that the prey animal has defences such as being unpalatable or poisonous. ... Aposematic signals are primarily visual, using bright colours and high-contrast patterns such as stripes.

30. Why do stars differ in brightness
Answer:
Stars have a wide range of apparent brightness measured here on Earth. The variation in their brightness is caused by both variations in their luminosity and variations in their distance. An intrinsically faint, nearby star can appear to be just as bright to us on Earth as an intrinsically luminous, distant star.
