Are speakers digital or analog? Are speakers analog or digital devices? Though speakers are regularly connected to digital audio devices, they are inherently analog transducers. Speaker transducers convert analog audio signals (electrical energy) into sound waves (mechanical wave energy). Are headphones analog or digital? Though headphones are regularly connected to digital audio sources, they are […]
What type of central heating system is best?
What type of central heating system is best? A gas fuelled central heating system will more than likely be cheaper in the long run. Electric boilers are 100% efficient whereas a good modern gas boiler will see about 95% efficiency. As you might expect, some energy from gas boilers is lost through heat. Are boilers […]
Why am I all of a sudden getting a lot of Facebook friend requests 2020?
Why am I all of a sudden getting a lot of Facebook friend requests 2020? The influx of friend requests for verified users is “likely due to recent search changes” on the platform, Facebook says, which were intended to more prominently surface search results for verified accounts over unverified ones.

How does a cell turn into a human?
How does a cell turn into a human? Over the course of hours, days, or months, the organism turns from a single cell called the zygote (the product of sperm meeting egg) into a huge, organized collection of cells, tissues, and organs. As an embryo develops, its cells divide, grow, and migrate in specific patterns […]

What is the importance of Glossopteris?
What is the importance of Glossopteris? They literally reveal how the world we recognise today took shape. Glossopteris was easy to recognise because of its distinctive leaves; the name means “tongue-fern” in Greek, because of its shape. Fossil evidence suggests that the plants probably grew in diverse habitats and came in different forms. What does […]
Did the electron move into a region of higher potential or lower potential?
Did the electron move into a region of higher potential or lower potential? Because the electron is a negative charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential. Because the electron is a positive charge and it accelerates as it […]
Can an object have infinite mass?
Can an object have infinite mass? Advertisement. So when we think of mass as energy, we can begin to understand why an object will increase its ‘mass’ as it speeds up. Since an object has infinite kinetic energy when it approaches the speed of light, it therefore has infinite mass as well. Does Goku have […]
