Answer:
Explanation:
Given data
Length L=0.24 m
Magnetic field B=7.0 T
Current I=90 A
To find
Number of turns N
Solution
As we know that magnetic field is given as:
Rearrange the equation and solve for N
So
Using Newton's Law of Cooling, the given are:
Temperature of the first bath (Ta1): 25C
a(final temperature)= 50C, b (initial temperature)=100C
x-y is the difference in time. In the first bath, 150s
dT/dt=-k(T-Ta)
ln (T-25) [from a=100 to b=50]= -k*150
ln ((50-25)/(100-25))= -k*150
Solving for k=7.324081X10^-3
For the second bath: find Ta2 with dt=120s
dT/dt=-(7.324081x10^-3)*(T-Ta2)
ln (T-Ta2) [from a=100 to b=50]= -(7.324081x10^-3)*120
ln ((50-Ta2)/(100-Ta2))= -(<span>7.324081x10^-3)</span>*120
Solving for Ta (second bath temperature)= 14.49 degrees Celsius
