question 26

Multiple Choice

For a long ideal solenoid having a circular cross-section,the magnetic field strength within the solenoid is given by the equation B(t) = 5.0t T,where t is time in seconds.If the induced electric field outside the solenoid is 1.1 V/m at a distance of 2.0 m from the axis of the solenoid,find the radius of the solenoid.

• A) 0.30 m
• B) 77 m
• C) 0.94 m
• D) 9.0 m

Definitions:

Significance Level

A threshold within hypothesis testing that determines whether to reject the null hypothesis, often denoted by alpha (α) and representing the probability of a Type I error.

Kilometres

A unit of length in the metric system equal to 1,000 meters, commonly used to measure distances between geographical locations.

Mean Number

The average value of a set of numbers, calculated by dividing the sum of all numbers by the count of those numbers.

Significance Level

In hypothesis testing, the threshold below which the p-value must fall for the results to be considered statistically significant, commonly set at 0.05.
