Answer:

C) Points 2 and 4

Explanation:

In a complete electric circuit, wires carry the current from the battery to the bulb and from the bulb to the battery. The wires should be attached to points 2 and 4 to make the bulb glow.

Answer:

The points 2 and 4 should be connected.

Explanation:

To complete the circuit, we need to connect the two points which when connected, encompass the battery and the bulb in the circuit. The points 2 and 4 do the job, since they connect the terminal of the battery and the terminal of the bulb, and thus complete the circuit.

Therefore,  the choice C is correct.

An infinitely long cylindrical insulating shell of inner radius a and outer radius b has a uniform volume charge density p. Dete
xenn [34]

Answer: The electric field is: a) r<a , E0=; b) a<r<b E=ρ (r-a)/εo;

c) r>b E=ρ b (b-a)/r*εo

Explanation: In order to solve this problem we have to use the Gaussian law in diffrengios regions.

As we know,

∫E.dr= Qinside/εo

For r<a --->Qinside=0 then E=0

for a<r<b er have

E*2π*r*L= Q inside/εo       in this case Qinside= ρ.Vol=ρ*2*π*r*(r-a)*L

E*2π*r*L =ρ*2*π*r* (r-a)*L/εo

E=ρ*(r-a)/εo

Finally for r>b

E*2π*r*L =ρ*2*π*b* (b-a)*L/εo

E=ρ*b* (b-a)*/r*εo

A 49.3 g ball of copper has a net charge of 2.0 µc. what fraction of the copper's electrons has been removed? (each copper atom
Serggg [28]
First, find how many copper atoms make up the ball: 
 moles of atoms = (49.3 g) / (63.5 g per mol of atoms) = 0.<span>77638</span><span>mol 
</span> # of atoms = (0.77638 mol) (6.02 × 10^23 atoms per mol) = 4.6738*10^23<span> atoms </span>

<span> There is normally one electron for every proton in copper. This means there are normally 29 electrons per atom:
</span> normal # electrons = (4.6738 × 10^23 atoms) (29 electrons per atom) = <span> <span>1.3554</span></span><span>× 10^25 electrons 
</span>
<span> Currently, the charge in the ball is 2.0 µC, which means -2.0 µC worth of electrons have been removed.
</span><span> # removed electrons = (-2.0 µC) / (1.602 × 10^-13 µC per electron) = 1.2484 × 10^13 electrons removed
 
</span><span> # removed electrons / normal # electrons = </span>
<span>(1.2484 × 10^13 electrons removed) / (1.3554 × 10^25 electrons) = 9.21 × 10^-13 </span>

<span> That's 1 / 9.21 × 10^13 </span>

As a wave moves through a medium, particles are displaced and (2 points)
Scorpion4ik [409]

As a wave moves through a medium, particles are displaced and return to their normal position after the wave passes.

Explanation:

A wave is a traveling disturbance that  carries energy from one location to  another. All waves move in straight lines  outward and away from the source of a  disturbance. Like the radiating circular  ripples, the waves of water carry energy  away from where a rock was dropped into  the pond.

Waves can move as a single pulse or as a continuous series of waves, carrying  energy away from its source. A pulse is a single disturbance, wave, or ripple that moves  outward from the point of disturbance. A train of waves are many waves emitted over and  over again from a single source.

As waves travel through matter, they will temporarily  displace the molecules or particles in matter up-and-down  or side-to-side. Waves move the energy but they do not  carry the matter with them longitudinally as they move  through matter. Once the disturbance passes, the medium  will return to its original state or position.

Therefore, as the waves move through a medium, particles are displaced and return to their normal position after the wave passes.
