A long solenoid has 1400 turns per meter of length, and it carries a current of 4.8 A. A small circular coil of wire is placed inside the solenoid with the normal to the coil oriented at an angle of 90.0\deg with respect to the axis of the solenoid. The coil consists of 54 turns, has an area of 1.2 x 10-3 m?, and carries a current of 0.80 A. Find the torque exerted on the coil.

Write a function that receives a two-dimensional array (4 X 5) of integers and then returns an integer number, which contains indices of columns containing the max value. Note: there might be several max values and the order of digits is not important. Input: 8 7 19 1 3 4 19 5 8 6 2 4 1 6 19 13 5 13 11 7 output: 124 (the max value is 19 and indices of columns containing 19 is 124)

Let B and C be bases for a vector space V. Determine whether the statement below is true or false. Justify the answer. The columns of the change-of-coordinates matrix P are B-coordinate vectors of the vectors in C. Choose the correct answer below. $C \leftarrow B$ A. The statement is true. For $1 \le i \le n$, $[\mathbf{b}_i]_C = \mathbf{b}_i$; therefore, $P_{C \leftarrow B} = [\mathbf{b}_1 \dots \mathbf{b}_n]$. B. The statement is false. The columns of the matrix $P_{C \leftarrow B}$ are the C-coordinate vectors of the vectors in C. C. The statement is true. For $1 \le i \le n$, $[\mathbf{c}_i]_B = \mathbf{c}_i$; therefore, $P_{C \leftarrow B} = [\mathbf{c}_1 \dots \mathbf{c}_n]$. D. The statement is false. The columns of the matrix $P_{C \leftarrow B}$ are the C-coordinate vectors of the vectors in B.
