Answer:
The magnetic field along x axis is
The magnetic field along y axis is zero.
The magnetic field along z axis is
Explanation:
Given that,
Length of the current element 
Current in y direction = 5.40 A
Point P located at 
The distance is
We need to calculate the magnetic field
Using Biot-savart law
Put the value into the formula
We need to calculate the value of 
Put the value into the formula of magnetic field
Hence, The magnetic field along x axis is
The magnetic field along y axis is zero.
The magnetic field along z axis is
Answer:
The fuse must be connected between the device and the power intake source.
Explanation:
A fuse is a protective component of electrical appliances that is designed to be sensitive to a particular range of electric current
The fuse is made of a thing metal strip with a known melting point. Once current abive its carrying capacity flows through it, large heat is generated in the metal strip which melts it and causes the metal strip to cut int two protecting the device from the power spike.
Given data:
- It is a graphical display where the data is grouped in to ranges
- A diagram consists rectangles, whose area is proportional to frequency of a variable and whose width is equal to the class interval.
- It is an accurate representation of the distribution of numerical data.
<em>From Figure:</em>
Each box in the graph (small rectangle box) is assumed to be one download. So, in the graph the time between 8 p.m to 9 p.m, the number of downloads are 8.75 approximately (because the last box is incomplete, therefore 8 complete boxes and 9th is more than half).
<em>So, We conclude that the total number of downloads are approximately 9 in the time span of 8 p.m. to 9 p.m.</em>
