What are Two reasons why one star would be brighter than another?
One reason could be that the brighter star is larger and hotter, emitting more light. Another reason could be that the brighter star is located closer to Earth, making it appear brighter in the sky.
Why do some stars appear bigger and brighter than others?
A stars brightness depends on two factors; its distance from us and its actual brightness (absolute magnitude). The actual brightness of a star depends on various factors, such as its mass, its temperature and its age.Consider two stars of the same actual brightness (absolute magnitude) - if one of them is much closer, then is will be brighter than the further one. It will appear brighter, even though it would be the same side by side - it can be said to be apparently brighter (higher apparent magnitude) due to its distance.A:They appear bigger and brighter because they really are bigger and brighter, but even if they are not bigger and brighter it could be because they are closer.
Is Pollux brighter than Castor?
It's a close call, but Pollux is brighter. Pollux has an apparent magnitude of 1.15 whereas Castor has an apparent magnitude of 1.96.(Note: the smaller the apparent magnitude the brighter it is)
Is sunnier an adjective?
Yes, "sunnier" is the comparative form of the adjective "sunny." It is used to compare two things or situations to indicate that one has more sunshine or is brighter than the other.
How long does the supermoon last?
A supermoon typically lasts for just one night when the full moon coincides with its closest approach to Earth in its orbit. The moon appears larger and brighter than usual during this time.
Out of the two bulbs in the house one glows brighter than the other which one of the two has a larger resistance?
The bulb that glows brighter has a smaller resistance. This is because a larger current flows through the bulb with smaller resistance, resulting in it glowing brighter.
Does strongness of two battry light a bulb stronger or not?
Yes, having two strong batteries will likely light a bulb brighter than just one battery. The combined voltage and current from the two batteries will provide more energy to the bulb, resulting in a brighter light.
Which is brighter 10 watts or 25 watts bulb?
That depends on so much more then just the watt of the bulb, but if you have two identical bulbs where the only difference is the amount of watt, then logic dictates that 25watt is brighter then 10watt
What would be different if only one light bulb were wired in this circuit instead of two?
I you wired a light bulb in to the same circuit you have the possibility of over loading the circuit but other than that it would just be brighter.
Can you make a bulb glow more brightly by adding a second battery?
Yes, two batteries will make a light bulb brighter than one, provided that the batteries are placed in series. The brightness of the bulb is determined by the voltage, and placing two batteries in series rather than just using one increases the voltage.
Which arrangement should be brighter when hitched to a single bulb 2 batteries in a series or 1 battery?
Two batteries in series will cause the bulb to burn brighter.
Two lamps A and B are rated 60W 220V and 100W 220V respectively so why does the answer say that when connected in parallal bulb A is brighter?
In parallel, they both obviously have 220 v across them, so the 100 W bulb is obviously brighter than the 60 W one. The 60 W bulb has more resistance, and in series they both have to pass the same current, so the 60 W has more voltage across it and might be brighter.
What happens in a series circuit with three different watt bulb's which bulb will brighter?
The 2 bulb series circuit , a 3 bulb series circuit will increase resistance and therefore reduce the voltage across the bulb. The current in all points of the circuit will remain the same according to Kirchhoff.
Why are two bulbs in parallel bright when you build a parallel circuit with two bulbs a one d- cell battery?
Two bulbs in parallel are brighter than the same two bulbs in series, given the same potential voltage, because there is twice the available voltage to each bulb.
What happens to a light bulb in series?
If you put two incandescent bulbs of the same wattage in series, they will both light with the same intensity. If one is lower wattage than the other, the lower wattage bulb will light brighter than the oter one. If you put two 115 volt bulbs of the same wattage in series across 230 volts, both will light equally, but if you use dissimilar wattages, the smaller one will burn out.
Is the planet jupiter brighter than stars?
For us, it looks brighter than any star, but this is because it is much nearer. Now (March/April 2012) you can see two bright "stars" in the west, after sunset - the brighter one is planet Venus, the second-brightest one is planet Jupiter. In terms of absolute brightness, a star is brighter than a planet.
What are Two reasons why one star would be brighter than another?
One reason could be that the brighter star is larger and hotter, emitting more light. Another reason could be that the brighter star is located closer to Earth, making it appear brighter in the sky.
