What is the name for the study of why objects move?
The study of why objects move is dynamics, whereas the study of how objects move is kinematics.
The total momentum of a group of objects is conserved unless what?
outside force's act on the objects. :3
What are the 3 laws of charges?
1.) Opposite charges attract. 2.) Like charges repel. 3.) Neutral objects are attracted to charged objects.
What ballasts are used for LEDs?
We don't use ballasts for LEDs. Ballasts are used with fluorescent lighting fixtures to both step up voltage to fire the tube and to provide an in-circuit load when the tube fires and conducts. LEDs have a series resistor either integral to the LED or separate to it which limits current in the LED when it is turned on.
What is the name for objects that repeat in a predictable way?
A pattern
Which is a more powerful light - 95 leds or 128 leds?
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
Can a 3 volt battery light 5 leds?
It depend on what the rating voltage of the LEDs are.
What things need to have an L.E.D.light?
Leds can be helpful when seeing if an object is on or off or has a signals. They can also be used for decoration on some objects.
When to connect LEDs in parallel?
Basically, when LEDs are connected in parallel, the LEDs with the lowest resistance will be the brightest, the other LEDs will be dimly lit or not lit at all. Therefore, use LEDs with the same model number and colour.
What is the name of solid figure?
Solid figures are normally classed as 3 dimensional objects
What are 3 things that visible light can be emitted by?
stars, flashlights, toasters, CFLs, LEDs, fireflies
How many colors do LEDs come in?
red, green, yellow, blue leds
Are colored Christmas tree leds the same as the leds used in grow lights?
No.
What has LEDs in it?
Most modern torches have LEDs in them, several newer models of Audis do too.
In what year did SemiLEDS Corporation - LEDS - have its IPO?
SemiLEDS Corporation (LEDS) had its IPO in 2010.
How many resistors are needed 2 light up 5 leds?
Resistors don't light up LEDs. They're required in a circuit along with LEDs in order to prevent excessive current through the LEDs when the LEDs are forward biased. The correct resistance value depends on the supply voltage and the desired (rated) current through the LEDs, and there's typically one resistor in series with each LED.
How are LEDs different from other artificial light sources?
The difference is that LEDs use less electricity.
