How can yield strength be reduced? For the majority of materials, the yield strength decreases with increasing temperature. In metals, this decrease in yield strength is due to the thermal activation of dislocation motion, resulting in easier plastic deformation at higher temperatures. What happens when plastic is cooled? Once a plastic has been cooled below […]
What is the difference between 0 and 180 phase?
What is the difference between 0 and 180 phase? The phase control operates over a range of 0 to 180 degrees. Setting the phase control to 180 degrees reverses the polarity of the subwoofer. In some application where the subwoofer is placed on a wall opposite from the speakers, reversing the subwoofer polarity can yield […]
Do humans have free will?
Do humans have free will? At least since the Enlightenment, in the 18th century, one of the most central questions of human existence has been whether we have free will. In the late 20th century, some thought neuroscience had settled the question. However, as it has recently become clear, such was not the case. What […]
Does salt and sugar affect water evaporation?
Does salt and sugar affect water evaporation? You are right in that the salt water and sugar water should have evaporated more slowly. The reason for this can be explained with some advanced chemistry, but I’ll try to explain in simpler terms so your son can understand it. Does salt water or pure water evaporate […]

What are the similarities and differences between replication and transcription?
What are the similarities and differences between replication and transcription? Both DNA replication and Transcription involve the generation of a new copy of the DNA in a cell. DNA transcription is involved in replicating the DNA into RNA, while the DNA replication makes another copy of DNA. Both the process is involved in the production […]
What are the 7 parts of a lab report?
What are the 7 parts of a lab report? Sections of a laboratory report: A typical report would include such sections as TITLE, INTRODUCTION, PROCEDURE, RESULTS, and DISCUSSION/CONCLUSION. What are the 8 steps of a lab report? That procedure is commonly called the scientific method and consists of the following eight steps: observation, asking a […]
What does adding baking soda to your laundry do?
What does adding baking soda to your laundry do? It may sound like an old wives’ tale, but adding baking soda to your regular amount of liquid laundry detergent truly will make your colored clothing brighter and your whites whiter. Baking soda is a natural deodorizer and cleanser, and it also softens the water, which […]
When we touch a metal spoon it feels cold Why?
When we touch a metal spoon it feels cold Why? A: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they’re good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects. How do you feel when you touch […]
Do LEDS have resistance?
Do LEDS have resistance? An LED (Light Emitting Diode) emits light when an electric current passes through it. The simplest circuit to power an LED is a voltage source with a resistor and an LED in series. Such a resistor is often called a ballast resistor. If the voltage source is equal to the voltage […]
