explain, how is t
there are 3 types of hybridisation for carbon in organic compounds, sp, sp2 and sp3 depending on the number of sigma and pi bonds between the carbon atoms. more the ‘s’ character more is the electronegativity of the carbon as ‘s’ orbitals are closer to the nucleus, hence electrons held more closely.
not understood actually. plz clarify in detail let me explain the... i know th answer check this video about. In the middle of the TT youll Find a C-Clip It needs to be Removed before the Platter can be removed,You either have a Broken Belt,Or the Grease in the Guide is Old and must be Cleaned out and Relubed Rule No.1 on Duolingo-Arabic: Do not pay attention to the audio. Or rather, not much attention to the audio. I've been working on correcting some things for learners here who were misled big time by the audio.  

The audio here is mainly a speech machine or TTS. The speech machine is not adequate and makes a lot of mistakes (even grammatical-wise) and there are many words out there that do sound funny when the TTS spells them out. To add salt to the wound: Duolingo uses some words and expressions from dialects and mixes them up with MSA (or modern standard Arabic). please We are given:  

\(\displaystyle{t}={t}{0}+{\left({\frac{{{k}}}{{{2}}}}\right)}{w}\)  

Subtract t0 from both sides:  

\(\displaystyle{t}-{t}{0}={t}{0}+{\left({\frac{{{k}}}{{{2}}}}\right)}{w}-{t}{0}\)  

\(\displaystyle{t}-{t}{0}={\left({\frac{{{k}}}{{{2}}}}\right)}{w}\)  

Multiply both sides by \(\frac{2}{k}\)  

\(\displaystyle{\left({t}-{t}{0}\right)}{\frac{{{2}}}{{{k}}}}={\left({\frac{{{k}}}{{{2}}}}\right)}{w}\cdot{\left({\frac{{{2}}}{{{k}}}}\right)}\)  

\(\displaystyle{\frac{{{2}{\left({t}-{t}{0}\right)}}}{{{k}}}}={w}\)  

\(\displaystyle{w}={2}\frac{{{t}-{t}{0}}}{{k}}\) thanks for the tip details  here
