A circular coil of radius 0.110 m contains a single turn and is located in a constant magnetic field of magnitude 0.320 T. The magnetic field has the same direction as the normal to the plane of the coil. The radius increases to 0.290 m in a time of 0.0740 s. (a) Determine the magnitude of the emf induced in the coil. (b) The coil has a resistance of 0.670 Ω. Find the magnitude of the induced current.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

13.46

step-by-step explanation:

16.80 x .20 = 13.46
