Answer:
9
Explanation:
bc I cant understand what your sayinnggggggg
Answer:
D. keep your hand and forearm in the same plane
Explanation:
The ergonomic principle explains how to maintain a good posture. And if hands and forearms are in the same plane then you will do least work, and hence not loss more energy, which you can lose if your elbows are close together while typing or your hand and forearm is not in the same plane, or your hands are crossed, or your neck is non aligned to your spines. And if you want to work more efficiently in your office, then you should study ergonomic principles certainly.
The answer would be false, an internet spy makes it easier for them to see everything.
Resposta:
<u>Per a càrrega de 680Ω:</u> 7,27 volts
<u>Per a les dues càrregues de 220Ω:</u> 2,36 volts cadascuna
Explicació:
Segons la llei d’ohms
E = IRt
E és la força electromotriu = 12V
I és el corrent total que circula al circuit
Rt és la resistència equivalent total
Com que els 680Ω, 220Ω i 220Ω estan en sèrie;
Rt = 680 + 220 + 220
Rt = 1120Ω
Obteniu el corrent total del circuit:
Recordem que: E = IRt
I = E / Rt
I = 12/1120
I = 0,0107A
<u>Tingueu en compte que el mateix corrent flueix a través de resistències connectades en sèrie, però tensions diferents.
</u>
Obteniu les tensions individuals;
Per a càrrega de 680Ω;
V = IR
V = 0,0107 * 680
V = 7,27 Volts
Per a la càrrega de 220Ω
V = IR
V = 220 (0,0107)
<em>V = 2,36 volts
</em>
<em>Per tant, les tensions de les dues càrregues de 220Ω seran de 2,36 volts cadascuna</em>
