Answer: A is your answer i am sorry if i am wrong

Explanation:

he first PLCs were programmed with a technique that was based on relay logic wiring schematics. This eliminated the need to teach the electricians, technicians and engineers how to program a computer - but, this method has stuck and it is the most common technique for programming PLCs today.

<span>A lot of things take up electricity. Just leaving something plugged in can cost energy that could have been used for something more worth while. I think the biggest thing people do that wastes energy is that we leave lights on when we don't need them. I would like to improve this method by turning my lights off everytime I exit the room or by not even turning on the light if I can see without it. If it is daylight outside and you have a window in the room and you can see perfectly fine without the light, then why turn it on? No one ever thinks about that. Leaing our lights on is a common factor that raises our light bills. We always think we are gonna come back into the room in a minute but it ends up being a hour later. That's valuable money down the drain because no one is in the room using the light.

An electron in a mercury atom jumps from level a to level g by absorbing a single
statuscvo [17]

Answer:

7.39ev

Explanation:

Energy levels are found inside the atom. Electrons occupy these energy levels depending on the energy they possess. Electrons can move from one energy level to another due to absorption or emission of a photon or other factors. As the electron, jumps from a higher energy level to a lower energy level emitting a photon of measurable frequency, the photon carries energy equal to the amount of energy between the gap of the levels. This idea was first proposed by Neils Bohr and became the forerunner of the wave mechanical model of the atom.

Hence the energy of a photon is the energy of the gap between the two energy levels. Since Ea= 2.48ev and Eg= 10.38 ev.

If an electron jumps from Ea to Eg, the energy of the photon absorbed is given by;

E=Eg-Ea

E= 10.38ev - 2.48ev

E= 7.39ev

Suppose you have measured the diffraction pattern of a grating with d = 0.19 mm and have found that the spots were separated by
cestrela7 [59]

Answer:

d = 0.076 mm

Explanation:

Given data

diffraction pattern d1 = 0.19 mm = 0.019 cm

separated s(1)  = 1.8 cm

separated s(2) = 4.5 cm

to find out

d2 for an unknown

solution

we know here that spacing in between the diffraction fringe is always inversely proportional to diffraction grating so

we will apply here formula for unknown d that is

d1 (s1 / L) = d2 (s2 /L)

d2  = d1 ×  s(1) / s(2)

put here all thes evalue we get d2

d2  = d1 ×  s(1) / s(2)

d2  = 0.019 ×  1.8  / 4.5

d2 = 0.0076 cm

d2 = 0.076 mm
