<h2>Answer:</h2>

<u>The Equivalent resistance is 2.17 Ohms</u>

<u>The current in 4 ohm resistor is 6 amps</u>

<u>The current in 4 ohm resistor is 3 amps</u>

<u />

<h2>Explanation:</h2><h3>Part 1</h3>

Equivalent resistance in parallel is given as

1/Re = 1/R1 + 1/R2  + 1/R3

By putting the values

1/Re = 1/4 + 1/8 + 1/12

Equivalent Resistance = 2.17 ohm

<h3>Part 2</h3>

By Using Ohm Law

V = IR

I = V/R

I = 24/4

I = 6 amp

<h3>Part 3</h3>

According to Ohms law

V = IR

I = V/R

I = 24/ 8

I = 3 amp

PART A)

Equivalent resistance in parallel is given as

\frac{1}{R} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3}

now we have

\frac{1}{R} = \frac{1}{4} + \frac{1}{8} + \frac{1}{12}

R = 2.18 ohm

PART B)

since potential difference across all resistance will remain same as all are in parallel

so here we can use ohm's law

V = iR

for 4 ohm resistance we have

24 = 4(i)

i = 6 A

PART C)

since potential difference across all resistance will remain same as all are in parallel

so here we can use ohm's law

V = iR

for 8 ohm resistance we have

24 = 8(i)

i = 3 A

The water skier has a mass of 73 kg. Find the magnitude of the
Papessa [141]

To solve this problem we will apply the linear motion kinematic equations, specifically the concept of acceleration as a function of speed and time, as well as Newton's second law.

PART A) Acceleration can be described as changing the speed in a period of time therefore,

a = \frac{V}{t}\\a = \frac{11}{8}\\a = 1.375m/s^2

Force is the proportional change between mass and acceleration therefore

F = (73)(1.375)

F= 100.375N

PART B) We will apply the same concept given but now we will change the time to 21s therefore:

a = \frac{V}{t}\\a = \frac{11}{21}\\a = 0.5238

Now the force

F = (73)(0.5238)

F = 38.23N

Older railroad tracks in the U.S. are made of 12 m-long pieces of steel. When the tracks are laid, gaps are left between the sec
Shkiper50 [21]

Answer:

0.005 m

Explanation:

length of steel (L°) = 12 m

initial temperature (T) = 16 degrees

expected temperature (T') = 50 degrees

We can find how large the gaps should be if the track is not to buckle when the temperature is as high as 50 degrees from the formula below

ΔL = ∝L°ΔT where

  • ΔL = expansion / gap
  • ∝ = linear expansion coefficient of steel = 12x10^{-6} C^{-1}
  • L° = initial length
  • ΔT = change in temperature

ΔL = 12x10^{-6} x 12 x (50-16) = 0.005 m

The absolute magnitude of a star________.

<span>The absolute magnitude of a star is how bright it would appear to us
if it were located ten parsecs (about 32.6 light years) from us.  So it's
a way of treating all stars equally ... on a "level playing field" ... and it

What is the best way to support your hypothesis
Diano4ka-milaya [45]

Answer:

Making a Hypothesis

Explanation:

-Research the subject of your question. Review the literature and find out as much as you can about previous information and discoveries surrounding your question.

-Develop an educated guess that answers your initial question. This is your hypothesis. Make a prediction based on your hypothesis and state it as a cause-effect relationship.
