PLZ ANSWER FAST!!!! THE FIRST ANSWE GETS BRAINLIEST

Answer:

F=dA  

dF=0  

d⋆F=⋆J  

where in fact the second equality is not needed because of the identity  d2=0 . In abstract tensor notation, these equations expand to

Fab=2∇[aAb]  

∇[aFbc]=0  

∇aFab=Jb  

where in the above, additional compact notation has been used to simplify things: square brackets mean antisymmetrizing indices, and the covariant derivative  ∇a  is related to a flat derivative  ∂a  and a connection  Γbac . Now, performing a 3+1 decomposition (here in flat space-time) Maxwell's equations break down as

∇⋅B⃗ =0  

∇⋅E⃗ =4πρ  

∂B⃗ ∂t=−∇×B⃗  

∂E⃗ ∂t=+∇×B⃗ −4πJ⃗ .  

In the above, there is yet more compactifying notation: the divergence is defined as

∇⋅v⃗ =∂vi∂xi  

and the curl is defined as

(∇×v⃗ )i=ϵijk∂vk∂xj.  

In the above, still more compactifying notation has been used, namely the Einstein summation convention. Written out in components, the divergence is

∇⋅v⃗ =∂vx∂x+∂vy∂y+∂vz∂z  

and curl is defined as

(∇×v⃗ )z=∂vy∂x−∂vx∂y  

and similarly for the other two components.

As you can see, the extremely compact and powerful notation

dF=0  

d⋆F=⋆J  

expands out to a large set of component equations—but they have the same content, so it's not very meaningful that the equations in components are much longer than in terms of differential forms.

As another example, Elson Liu answered with an exploded-out form of the Standard Model Lagrangian. However, it can be written much more compactly:

L=LYM+LHiggs+Llep.+Lqrk.+LYuk.  

where

LYM=−14TrFabFab  

LHiggs=−(Daϕ†)(Daϕ)+14λ(ϕ†ϕ−12v2)2  

Llep.=iℓ†I/DℓI+ie¯†I/De¯I  

Lqrk.=iq†I/DqI+iu¯†I/Du¯+id¯†I/Dd¯I  

LYuk.=−yIJϕℓIe¯J−y′IJϕqId¯J  

−y′′IJϕ†qIu¯J+h.c.  

and specifying that F is the curvature on the gauge group  G≃SU(3)⊗SU(2)⊗U(1) ,  Da  is the gauge covariant derivative on G,  /D  is the gauge covariant Dirac operator on G, and specifying the representations of the fields: the scalar  ϕ  in the rep (1,2,-1/2), and the fermions  ℓ  in the rep (1,2,-1/2),  e¯  in (1,1,+1),  q  in (3,2,+1/6),  u¯  in  (3¯,1,−2/3) , and  d¯  in  (3¯,1,+1/3) ; where I is a generation index running over 1,2,3, and where everything else is a constant.

Step-by-step explanation:

Answer:

A 4/5 × 10 1/2 =8.4

B 2 1/2 × 16/5 =8

C 3 2/3 × 2 1/2 = 330/36 = 9.1666

D 20/3 × 9/10 =6

C IS THE GREATEST because 9.166 is greater than 8.4, 8 and 6

Answer:

1) x-3=0

Step-by-step explanation:

Answer:

Alright Ima jsut say common phrases and do em at the end

Veritcal angles:

Well these angles are equal and always across form each other. Too determine if its a vertical angle, if you see an “x” Like shape, you can draw a maximum of two lines, one horizontal, one vertical. The number those lines tough are vertical the fore the SAME.

Complementary angles:

These are 2 or more angles that add up to 90 degrees. You can have like 20 different angles with different numbers, as long as they add up to 90 degrees. 90 degrees is a right angle so no matter what, it has to equal 90 degrees from all angles.

Supplementary angles:

These are 2 or more angles that add up to 180 degrees or a straight line more common. As long as all the angles add up to 180, its supplementary.

Adjacent angles:

These are angle show lie next to each other. They don’t have anything special, their just next to each other. Ima use an example form the graph. Take for example the angle RNX. XNE is adjacent, its lies right next to it. Another Example could be KND. DNE is adjacent, right next to it.

1) ANR

2) KNE

3) KND

4) RNX

Answer:

Yes.

Step-by-step explanation:

Although there is not much info on this question, if you were to assume that there are 3 different answers or 3 different methods of solving that problem, it is definitey possible to assume that this is possible.

The probability of the spinner landing on A is 3/8, the probability of the spinner not landing on C or E is 1/2

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

1) What is the probability of the spinner landing on A:

Total outcomes = 8

Total favourable = 3 (A repeated 3 times)

Probability = 3/8

2) Do you have an equal chance of landing on either B or E:

No, because the probability for B is 1/8 and the probability for E is 3/8

3) What is the probability of the spinner not landing on C or E:

P(not landing on C or E) = 4/8 = 1/2

4) Do you have an equal chance of landing on either B or C:

Yes, because both event has same probability = 1/8

5) What is the probability of the spinner not landing on A or E:

P(not landing on A or E) = 2/8 = 1/4

6) What is the probability of the spinner landing on C or E:

P(landing on C or E) = 4/8 = 1/2

7) What is the probability of the spinner not landing on A or B:

P(not landing on A or B) = 4/8 = 1/2

Similarly, we can find the rest of the probability.

Thus, the probability of the spinner landing on A is 3/8, the probability of the spinner not landing on C or E is 1/2

#SPJ2

Answer:

V=14

Step-by-step explanation:

Well its a supplementary angle if you add everything together.

We know theres a 90 degrees angle and a 34 degree angle.

90+34=124

124+4v=180

Since if you add everything up its a straight line

Solve the equation normally

56=4v

14=v

Answer:

1- alternate exterior

2-vertical

3- linear/supplementary

4-alternate interior

5-same side interior

6-corresponding

hope this helps! have a lovely day :)
