A long straight wire carries a current of 1.0 A.
(a) At what distance from the wire is the magnitude of the magnetic field
equal to 2.5 x 10^-5 T?
(b)What is the magnitude of the magnetic force that this wire will exert on a
3.0 nC particle moving at 4.2 x 10^4 m/s perpendicular to the field at that
distance?
A 55.0 m wire carries a current of 2.25 A in a location where Earth’s
magnetic field is 4.5 x 10^-3 T. The wire experiences a force of 0.15 N. Find
the angle between the wire and the magnetic field.

Write a program that declares and initializes an array of 7 integers. The program uses these static methods to perform different operations on the array:
void printArray(int[] arr) – takes the array as parameter and prints the array in horizontal order
int sumOfArray(int[] arr) – takes the array as parameter and returns the sum of the array
int getHighest(int[] arr) – takes the array as parameter and returns the highest value in the array
int resetArray(int[] arr) – takes the array as parameter and resets the value of each element to 0
Sample output:
Here’s the array:
3 1 3 2 1 9 1
Sum: 20
Highest: 9
Here’s the array:
0 0 0 0 0 0 0
The variance of a population is 3.26. If a sampling distribution of the sample mean is constructed from the population with a sample size of 3, what is the variance of the sampling distribution of the sample mean?
