The magnetic field strength is 17 Weber.
<h3>How can we find the value of magnetic field?</h3>
We know, The magnetic field equation is given by:
<h3>Given,</h3>
Where, we know,
= 
= It is the magnetic constant or the permeability of free space.
n = The turn density which is equivalent to number of turns per unit length = 3300 turns per meter = 3300 
I= the amount of current applied to it = 4. 1 kA = 4 × 
A.
We have to find the magnetic field strength = B
Substituting the known values into the equation gives the strength of the magnetic field, which is:
[We know, 
]
So, from the above calculation we can see that, The magnetic field strength is 17 Weber.

<u>Explanation for the given picture:</u>
Initially, three principles of movement proposed by Sir Isaac Newton in 1686 "Principia Mathematica Philosophiae Naturalis". The third law says that every action (force) in nature has an equal but has opposite reaction.
In other words, when object A produces force on object B, then this object B also exerts the same but opposite forces on object A. Remember that forces get exerted on various objects. For example, if we put a wooden block in the floor, this block will create a force that should be equal to its mass, W = mg, which will work down.
The photo above clearly shows a person jumping off a tree on a wooden board, and therefore bouncing on the board because of the force exerted by the wooden board. Newton's third law is important if a person uses his power as weight (W = mg), and this in turn turns the person upside down! hence
Newtons 3rd law applies in above picture.
Given that : d = 5sin(pi t/4), So, maximum displacement, d = 5*(+1) = 5 Also, maximum displacement, d = 5*(-1) = -5
Answer:
Experimental
Explanation:
Here the dependency of pressure on the temperature is to be determined. For finding this factor we need to calculate the pressure of the object at different temperature.
The process of calculating pressure for different temperature is experimental investigation because we need to perform this experiment for finding these value. On the basis of observed values the we can conclude the dependency.
Thus, this investigation is experimental.
