Mwanafunzi, weka swali linalokusumbua ili walimu na wazoefu wakusaidie

mwenye kukumbuka derivations ya inverse of coseh plz afanye kisha apige picha na kuweka hapa since there's some place nafail during derivation guys
 

Eti ukiwa na cheti cha AIRFAIR&TICKETING WITH TOUR GUIDING OPERATION cha short course unaweza kuapply diploma ya UALIMU,IT NA ACCOUNTING? Au ni dploma gani naweza kuapply?msaada tafadhalini..Asanteni🙏
 
Ni ngumu kuaply kitu tofauti kwakutumia cheti kisicho ma uhusiano na taaluma mpya unayotaka kusomea.
Nashauri utumie cheti cha elimu inayofahamika (CSEE & ACSEE) kuomba kitu kimya

-NAOMBENI MSAADA WAKUU...
Magnesium will displace copper from copper (II) sulphate solution according to the equation,
CuSO₄(aq)+Mg(s)--->Cu(s)+MgSO₄(aq)
When excess of magnesium was added to 100cm³ of 0.1moldm⁻³ Copper(II) Sulphate,The temperature increased by 46.3ºC.It is known that The density and specific Heat capacity of the solution are 1gcm⁻³ and 4.18JgºC⁻¹ respectively,Calculate
i)The molar Enthalpy Change for the reaction
ii)Minimum quantity of magnesium required
iii)The change in Temperature if only 0.8g og Mg was added
 
sauti ya radi ilisikika sekunde ya 10 baada ya mwanga wa radi , tafuta umbali wa mawingu ikiwa speed ya sauti hewani ni 340m/s na speed ya mwanga ni 300000000m/s .
Consider,
Let the distance be d
''Since they were both started at the same time'' let T be the time taken by light
V=d/t....(since v is uniform)
For light
C₀=d/T
T=d/C₀...1
For sound
V=d/(T+10s)
(T+10s)=d/V
T=d/V -10s .....2
equate eqn 1 and 2
d/V -10s=d/C₀
d(1/V-1/C₀)=10
d=(10xC₀V)/(C₀-V)
d=3400.003853m
 
asante mkuu
