I'm feeling defeated by the following circuit where I'm asked to find the total resistance. I can't make any sense of the correct answer, fear that I'm misunderstanding the basics about which parts are in series/parallel - would someone please calculate this and briefly explain the steps involved to get there?
My mum has had a pair of Phonak Audéo I50-R aids for the last year. She has always answered phone calls on the phone itself and had easy conversations over Bluetooth, but is now envious of her friend answering calls with a simple tap on her aid (different make model, I presume).
Reading the manual suggests that my mum should be able to do the same with a short press of the button on the aid, but it doesn't work. Can someone confirm, or not, that the I50 model can answer calls in this way? Is it a function that her audiologist has perhaps disabled?
I'd be grateful to have the correct "Discrete covalent molecular" answer to the following problem explained to me, please:
While I can understand this answer given the "small group of atoms" and "shared pair of electrons" clues, the combination of the metal and non-metal in a compound has me automatically assume ionic bonding as a catch-all.
The same website (BBC Bitesize) has the following as the first lines describing covalent and ionic bonding:
>A covalent bond is a shared pair of electrons between atoms of two non-metal elements.
Ionic bonds are formed between a metal and non-metal...
Are these statements a bit misleading in sounding so definitive?
These plants have sat happily on the kitchen windowsill over winter, occasionally watered and now a solitary beautiful flower is slowly appearing. The rest of it is just a healthy mass of leaves. Is there something I can do to promote more flowers? The plants mean a lot to us, I'm a novice and don't want to blindly try anything that might kill it.
