This question involves the concepts of th magnetic field and current.
The magnetic field created by the current at the house is "6.75 x 10⁻⁷ T".
<h3>Magnetic Field</h3>
The magnetic field created by a current carrying wire can be given by the following formula:
where,
- B = magnetic field = ?
- = permeabiliy of free space =4π x 10⁻⁷
- I = current = 152 A
- r = distance = 45 m
B = 6.75 x 10⁻⁷ T

Answer: +2.10V
Explanation:
Using Nernst equation :
where,
= standard emf for the cell = +2.20 V
n = number of electrons in oxidation-reduction reaction = 6
= emf of the cell = ?
= concentration =
= concentration =
Now put all the given values in the above equation, we get:
The standard emf for the cell using the overall cell reaction below is +2.10 V
If ball return to the hand of player then we can say that displacement of ball will be zero
so here we will have
so here we will have
so it will take 1 second to come back in its hand
Its either B. force or A. net force but I will go with force because forces can either push or pull I hope it help you.
C.) <span>The total mass of an object can be assumed to be focused at one point, which is called its center of "Mass"
Hope this helps!</span>
