How much work is being done if a force of 75 Newtons is used to push a box a distance of 100 meters?

How to tell if a circuit is connected in.a series.or parallel?

stepladder [879]

Series circuits split the voltage of resistors, so if you see several diodes connected in series or all next to each other, just a complete loop, it will be in series.

Parallel circuits split the current of resistors, so if you see several diodes connected along different branches or pathways, it will be in parallel.

The SAME amount of current I passes through three different resistors. R2 has twice the cross-sectional area and the same length

Snezhnost [94]

Answer:

resistor R₂ has the lowest current density

Explanation:

The current density is

j = I / A

now let's analyze each case

a) R₂ has an area 2A₀ and a length L₀ that R₁

b) R₃ has an area Ao and a length 3L₀ what R₁

we can see that all the area is given in relation to the resistance R₁

the current density in R₁ is

j₁ = I / A₀

the current density in R₂

j₂ = I / 2A₀

j₂ 2 = ½ I/A₀

the current density in R₃

j₃ = I / A₀

j₂ < j₁ = j₃

therefore resistor R₂ has the lowest current density

State in which atoms or molecules are very close together and are regularly arranged

umka21 [38]

Solid, because the atoms maintain their form and do not take the shape of their container. The particles share tight, close bonds due to this set shape
