Static electric fields are caused by charged particles when the atoms which compose the particle will have the same number of electrons as protons.
Each point in space has an electric field associated with it when the charge of any kind is present. The value of E, often known as the electric field strength, electric field intensity, or just the electric field, expresses the strength and direction of the electric field.
Both the electromagnetic wave produced by a radio broadcast monopole antenna and the field created in the dielectric of a parallel-plate capacitor are examples of electric fields (which create a time-varying field). Every place in space where a charge, regardless of its shape, is present is said to have an electric field, which is an electric attribute. The electric field's equation is given as E = F / Q.

I think it’s D) all of the above
Answer:
294.0724 N/C
Explanation:
From the question, we are given the following parameters: linear charge density,α = 4 nC/m = 4 × 10^9 C/m, radius, r= 2.5 m, the angle in the counter clockwise direction from the positive x-axis= θ= 287° and the Coulomb constant,Kc= 8.98755 × 109 N · m2 /C 2.
So, we can solve this question by using the formula below;
==>E(x direction)= - (Kc ×α )/ r × {sin 287° - sin 0°} i.
==>> - (8.98755 × 10^9 × 4 × 10^-9)/2.5 × { −0.9563047559630354
- 0} I.
==> -14.4 × [−0.9563047559630354].
==> 13.8 N/C i.
E( y direction)= - (Kc ×α )/ r × ( cos 0° - cos 287°) j.
==> -14.4 × (1 - [ 0.29237170472273672]).
==>( -14.4 × 0.7076) j.
==> - 10.18944 n/C j.
==>E(x direction)^2+ E( y direction)^2.
==> (13.8^2 + (- 10.18^2) N/C.
==> 190.44 N/C. + 103.6324 N/C.
= 294.0724 N/C
The reason that land is significantly cooler than the ocean is because of land breeze. Sea breeze is what makes oceans colder than land during the day, but when night happens, the heat from the land goes into the ocean, changing temperatures of both sides.
