Answer:

The answer to your question is the letter B. R = 8/7 Ω

Explanation:

Data

R1 = 2 Ω

R2 = 4Ω

R3 = 8Ω

To calculate the total resistance use the formula

         1/R = 1/R1 + 1/R2 + 1/R3

-Substitution

         1/R = 1/2 + 1/4 + 1/8

- Look for the Greatest common factor

              2   4   8    2

               1   2    4   2

                    1    2   2

                          1

The GCF = 2 x 2 x 2 = 8

-Sum up the fractions

                 1/2 + 1/4 + 1/8 = (4 + 2 + 1) / 8

                                        = 7/8

-Find R

               1/R = 7/8    then, R = 8/7 Ω

The ideal gas law is represented by PV=nRT. As volume is held constant and the temperature increases, how would the pressure be
nydimaria [60]

The pressure would increase as per Charle's Law, therefore the correct answer is option 4.

<h3>What is an ideal gas?</h3>

It is an imaginary gas for which the volume occupies by it is negligible, this gas does not exist in a practical situation and the concept of an ideal gas is only the theoretical one,

PV = nRT

As given in the problem statement we have to find out if the volume is held constant then what would happen to the gas if the temperature is increased,

For constant volume, the pressure of a gas is directly proportional to the temperature of the gas,

Thus, the pressure would increase as per Charle's Law, therefore the correct answer is option 4.

Katena32 [7]

Answer:

400.7886829 rad/s

Explanation:

First we have to turn our 0.35 rev/s into rad/s using the equation

(Xrev/s)*2pi=Xrad/s we can plug in .35*2pi=.7pi rad/s

Now we can us the equation m_1*v_1*r_1^2=m_1*v_2*r_2^2 we can plug in the given. Because the mass remains the same we can cross it off of both sides giving us just: v_1*r_1^2=v_2*r_2^2

(.7pi)*(.54)^2=(v_2)*(.04)^2

(.20412pi)=(v_2)*(.0016)     [.20412pi=.6412618925]

then using division on both sides we get

(.6412618925/.0016)=v_2=400.79rad/s(This answer is rounded to the nearest hundreth)

I personally would write it in a Ballad format.
Ballad poems tell a story.

Narrative poems tells a story often making the voices of the/a narrator or character.

Haiku poems rarely rhyme. 

Sonnet poems are rhythmic.
