Three resistors having the same resistance value are wired in parallel. How does the equivalent resistance compare to the resist

ance value of a single resistor?

vfiekz [6]3 years ago

Answer:The equivalent resistance is less than the resistance of a single resistor

Explanation:

Imagine three 3-ohm resistors connected in parallel.

1/Req= 1/R + 1/R + 1/R

1/Req= 1/3 + 1/3 + 1/3

equivalent resistance is [3(1/3)^-1]=1ohm

This is less than the individual resistance of each of the original three ohm resistors. Hence the answer.

Explain how living things such as people and trees are different from non living things such as rocks and tents
Musya8 [376]
The difference between living things and nonliving things is little things that we call is senses like sight, taste, touch, smell, and hearing. For example a human or animal can react to someone or something touching them. For a nonliving thing such as a rock can't react to someone touching them unless u force them to.

If an object falls far enough, it will reach terminal velocity. At this velocity, the force of air
love history [14]

Answer:

The object will contine to fall, but at a constant velocity.  There will be no more acceleration.

Explanation:  When the force of gravity is equal to the reverse force of air resistance, there will will be no net force on the falling obect.  F = ma, and F (net) = 0.  It will continue at the same speed until those forces become imbalanced again (such as when the force pushing up from the ground is greater than the force of gravity pulling it down).  The metric term for this sudden resistance is "crash/bang/clunk/yieouch."

A parallel-plate vacuum capacitor has 8.38 j of energy stored in it. the separation between the plates is 2.30 mm. if the separa
avanturin [10]
<h3><u>Answer;</u></h3>

= 4.19 Joules

<h3><u>Solution;</u></h3>

Energy stored in capacitor = U = 8.38  J

U =(1/2)CV^2

C =(eo)A/d

C*d=(eo)A=constant

C2d2=C1d1

C2=C1d1/d2

Initial separation between the plates =d1= 2.30mm .  

Final separation = d2 = 1.15 mm

But; Energy=U =(1/2)q^2/C  

U2C2 = U1C1

U2 =U1C1 /C2

U2 =U1d2/d1

Final energy = Uf = initial energy × d2/d1

                                = 8.38 ×1.15/2.30

                                = 4.19 Joules

Thus; The final energy = 4.19 Joules

What is the electromagnetic spectrum?
Pavel [41]
What is the electromagnetic spectrum?
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10²⁵ hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus.

How the light affect the color we see?
All of the colors we see are a byproduct of spectrum light, as it is reflected off or absorbed into an object. An object that reflects back all of the rays of light will appear white; an object that absorbs all of the rays, black. All of the millions of other colors are produced by a combination of light rays being absorbed and reflected.
