Answer:
Explanation:
Using Coulomb's Law we know that the electric field E at point
is:

where
is the Coulomb's Constant, q is the source charge, d is the distance between point and position of the source point charge, and
is the position of the source point charge.
Taking all this in consideration, the unit vector clearly is:

For our problem,
, as the charge is located at the origin.
So

and d will be the magnitude of 
Now, we can take the values for each point.
<h3>a.</h3>

and, the magnitude of the vector is



So, the unit vector is:



<h3>b.</h3>

and, the magnitude of the vector is



So, the unit vector is:



<h3>c.</h3>

and, the magnitude of the vector is



So, the unit vector is:



Answer:
Most commercial aircraft typically fly at around 460-575 mph, or 740-930 km/h, according to Flight Deck Friend. But private jet speed can vary depending on a variety of factors, such as the weight onboard and the weather conditions.
<span>Tech A is correct. An evaporator is part of the heat exchange system in a vehicle. Sometimes vehicles will have more than one evaporator, each located in different areas of the vehicle. A condenser is part of the air conditioner system, and only one is normally required.</span>
Answer:
Coil 2 have 235 loops
Explanation:
Given
The number of loops in coil 1 is n
₁=
159
The emf induced in coil 1 is ε
₁
=
2.78
V
The emf induced in coil 2 is ε
₂
=
4.11
V
Let
n
₂ is the number of loops in coil 2.
Given, the emf in a single loop in two coils are same. That is,
ϕ
₁/n
₁=
ϕ
₂
n
₂⟹
2.78/159
=
4.11/
n
₂
n₂=
n₂=235
Therefore, the coil 2 has n
₂=
235 loops.
Energy is measured by joule(j)
