Which changes would changes would correspond to a decrease in a star's absolute brightness?
A decrease in the star's temperature
Why does the dark matter theory explain the decrease in brightness of spiral galaxies?
The decrease is caused because it makes the spiral galaxy move further apart.
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 does closing the iris diaphragm affect image brightness and contrast?
An iris diaphragm controls the amount of light admitted to a lens. Closing the iris diaphragm will decrease the brightness and increase the contrast of an image.
What affects absolute brightness?
Brightness corresponds to amplitude of waves. Greater amplitude means greater brightness (so lower amplitude means less brightness).
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.
Which changes would changes would correspond to a decrease in a star's absolute brightness?
A decrease in the star's temperature
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.
Why does the dark matter theory explain the decrease in brightness of spiral galaxies?
The decrease is caused because it makes the spiral galaxy move further apart.
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.
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?
