Which changes would changes would correspond to a decrease in a star's absolute brightness?
A decrease in a star's absolute brightness could be caused by the star moving farther away from Earth, interstellar dust blocking some of its light, or a decrease in the star's temperature. All of these factors would result in less light reaching Earth, causing a decrease in the star's apparent brightness.
The current is 0.4 A and the bulb in the circuit is bright. What will happen to the brightness of the bulb if you put another bulb in series in the circuit?
ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down.
How to adjust brightness on kobo touch?
To adjust the brightness on a Kobo Touch, tap on the top of the screen to bring up the menu, then select the "Brightness" icon. You can slide the brightness bar left or right to decrease or increase the brightness according to your preference. If your device has light sensors, it may also have an automatic brightness adjustment feature that can be turned on or off in the settings.
The earth is moved from 1 au from the sun to 2 au from the sun how is the apparent brightness of the sun as seen from earth affected?
The apparent brightness of the sun would decrease because the intensity of sunlight weakens with distance. By moving the Earth from 1 AU to 2 AU, the distance between the Earth and the Sun doubles, resulting in a decrease in the amount of sunlight reaching Earth and causing a decrease in apparent brightness.
Why does the dark matter theory explain the decrease in brightness of spiral galaxies?
The dark matter theory explains the decrease in brightness of spiral galaxies because dark matter does not emit, absorb, or reflect electromagnetic radiation, making it invisible to telescopes that rely on detecting light. The presence of dark matter provides extra mass in the galaxy, which affects the gravitational interactions within the galaxy and with other galaxies in a way that accounts for the observed decrease in brightness at large distances from the center.
What will happen to the lamp if current decreases?
brightness will decrease
What happens to the brightness of the star as you observe it from farther away?
The brightness of star will decrease as you observe it from farther away.
What happen to the brightness of a star as you observe it from farther away?
The brightness of star will decrease as you observe it from farther away.

How does added resistance affect the brightness of the bulb?
Added resistance in a circuit will decrease the current flowing through the circuit, resulting in a decrease in the brightness of the bulb. This is because the bulb's brightness is directly proportional to the current passing through it. More resistance means less current, which leads to reduced brightness.
What is f1 on a Mac?
On a Mac, the F1 key decreases brightness, unless your Mac is set to do otherwise. Decrease brightness is the default. To increase brightness, press the F2 key.
What will happen to the brightness of blub connected in series with a solenoid with a source of dc?
THE brightness would decrease as solenoid would have some resistance.
Which circuit can decrease the fluorescent brightness to the minimum amount?
You need to purchase a Fluorescent dimmer switch, no circuit can dim the brightness of the light safely.
Is there a filter that can decrease the brightness of a bulb?
A: It is not a filter but rather a limiting resistor for the current.
How do we decrease the brightness of a bulb?
If the bulb is of the incandescent variety, then reducing the current in the circuit will do this.
The current is 0.4 A and the bulb in the circuit is bright. What will happen to the brightness of the bulb if you put another bulb in series in the circuit?

You are building a string of lights using several bulbs how is the brightness of the lights related to whether you connect the bulbs in series or in parallel?
Overall brightness (not individual bulbs' brightness) will increase when we connect them in parallel & it will decrease when we connect them in series.
