0.008 degC^-1 is alpha ... its not 1/alpha ... that's what is wrong...
1/alpha will have the unit deg celsius. only then you can add it with T0 ..
What you have taken as alpha is actually 1/0.008 degC^-1 ... so your 1/alpha will have the units degC^-1 so you cannot add it to T_{0}
In a...

And try this question out ... I think all the information necessary for solving this question has been provided there ...
The decibel is a logarithmic scale. The decibel level can be calculated by
\beta=10\log_{10}{\frac{I}{I_{0}}}
where I_{0} is a constant reference intensity = 10^{-12}W/m^{2} This is roughly the intensity of a just audible sound.
Your problem can be solved only if the intensity of the chain...
The field is indeed given by
B=\frac{\mu_{0}NI}{L}
and the total flux through the solenoid
\phi=NAB is also right.
Maybe what they asked for is the flux through a single turn which would be your answer divided by N
Also keep in mind that
B=\frac{\mu_{0}NI}{L}
is valid only for a long...
For Average velocity
Find the final displacement of the particle from the initial position. Then divide this by the total time taken.
For average speed
Find the total distance traveled by the particle. Divide this by the total time taken.
i'm not sure of this ... but
i think we can do this problem like radioactivity problems...
for the first part
given that half-life = 4s. Now calculate deacy constant which is ln2/(half-life period)...
The decay constant is defined as inverse of time taken to decay to 1/e times the original...
the question is :
suppose the resonance frequency of the LCR series circuit is f[SIZE="1"]r. Will the current in the circuit lag behind the voltage or lead the voltage in the following cases :
(i) when the applied AC frequency f > f[SIZE="1"]r
(ii) when f < f[SIZE="1"]r
we can say that the...
