Describe three objects in your house that use LEDs ​

Firlakuza [10]3 years ago

Answer:

1. Accent Lighting: Often used on stair wells and kitchen islands, LED accent lighting is a cost-effective way to light your home at night – and avoid stubbing your toe in the middle of the night. It’s also effortless to recreate using flexible LED strips or rope lights, which can fit almost anywhere.

2. Faucets & Showerheads: Adding LEDs to a bathroom or kitchen faucet, or a showerhead, produces a neat, futuristic effect especially when paired with streamlined chrome. All you’ll need to do is install a new showerhead to enjoy a shower in bright blue or purple hues. There’s even a designer line of LED sinks and tubs if you care to extend the look to the rest of your bathroom.

3. Wallpapers: LED walls are nothing new; folks have been rigging those up through various methods for years, but now there is LED wallpaper – in a few different styles from high-tech geekery, to more subtle designs. If that’s far too much effort, you can still take part in the trend with the LED wave projector, which drapes your wall in cool blue tones. There are also some lovely ceiling designs that use fibre optics that would probably be quite easy to duplicate with LEDs as well.

4. Centerpieces: Much like adding a tiny, cool plastic LED light disk into a faux candle provides you with a warm flame effect, putting colored LED disks into centerpieces will add atmosphere to the party. Likewise, waterproof LEDs can be added to glasses, and strands of LEDs can be worked into flower arraignments.

5. Planter Pots: Green thumbs don’t get left out when it comes to LEDs – far from it. In fact, LEDs are commonly used to help plants grow. So, an LED planter pot is another perfect combination of style and substance. Studio Shulab’s Lightpot and Rotoluxe both have excellent examples; Firebox has a solar powered version.

Hope it helps

Three groups of students are given study outlines for 6 weeks. One group studies 2 hours a night, a second group studies 1 hour
katrin2010 [14]

Answer:

The constant here is the study outline

Explanation:

In scientific research, the constant variable is that part/variable of the experiment that does not change or is set not to change. Examples include temperature, environment or height.

Assuming the scenery described in this question is an experiment. All the groups presented are bound by a constant during the experiment. The constant here is the study outline. The study outline provided to the students is not going to change.

NOTE: There could be confusion as regards the answer being the final exam grade but that will be the dependent variable as that will be the outcome of the experiment while the time spent to study will be the independent variable.

A student checks her car's tyre air pressure at a petrol station and finds it is 31 psi. Re-express this as an absolute pressure
victus00 [196]

Answer:

Absolute Pressure=315.06256 kPa

Explanation:

Gauge pressure= 31 psi

Atmospheric Pressure at Sea level= 1 atm=101.325 kPa

1\ psi=6.89476\ kPa\\\Rightarrow 31\ psi=31\times 6.89476\\\Rightarrow 31\ psi=213.73756\ kPa=Gauge\ Pressure\\Absolute\ Pressure=Gauge\ Pressure+Atmospheric\ Pressure\\\Rightarrow Absolute\ Pressure=213.73756+101.325\\\therefore Absolute\ Pressure=315.06256\ kPa

Voltage signals are generated on the output of a piezoelectric pressure transducer that is equipped with an amplifier.
Tema [17]

Answer: True

Explanation: Piezoelectric pressure transducers are equipments that helps to generate voltage through the mechanical actions such as applied pressure. Piezoelectric transducer is made up of quartz crystals which are made of silicone and oxygen formed in a crystalline structure.

Piezoelectric transducer can also be described as a Piezoelectric sensor as it helps to detect electric voltage generated through applied pressure.

Determine the change in the enthalpy of helium, in kJ/kg, as it undergoes a change of state from 100 kPa and 20 oC to 600 kPa an
MatroZZZ [7]

Answer:

The change in enthalpy of helium is 4073.86kJ/kg

Explanation:

∆H = Cp(T2 - T1)

Cp = 3.5R = 3.5×8.314 = 29.099kJ/kgmolK ÷ 2 (1kgmol of helium = 2kg of helium) = 14.5495kJ/kgK, T2 = 300°C = 300+273K = 573K, T1 = 20°C = 20+273K = 293K

∆H = 14.5495kJ/kgK(573K - 293K) = 14.5495kJ/kgK × 280K = 4073.86kJ/kg
