In The Diagram, R1 = 40.0 ,R2 = 25.4 Q, And R3 = 70.8 Q. What Isthe Equivalent Resistance Of The Group?Reg

Answers

Answer 1

Answer:

51 Ω.

Explanation:

We'll begin by calculating the equivalent resistance of R₁ and R₃. This can be obtained as follow:

Resistor 1 (R₁) = 40 Ω

Resistor 3 (R₃) = 70.8 Ω

Equivalent Resistance of R₁ and R₃ (R₁ₙ₃) =?

Since the two resistors are in parallel connection, their equivalent can be obtained as follow:

R₁ₙ₃ = R₁ × R₃ / R₁ + R₃

R₁ₙ₃ = 40 × 70.8 / 40 + 70.8

R₁ₙ₃ = 2832 / 110.8

R₁ₙ₃ = 25.6 Ω

Finally, we shall determine the equivalent resistance of the group. This can be obtained as follow:

Equivalent Resistance of R₁ and R₃ (R₁ₙ₃) = 25.6 Ω

Resistor 2 (R₂) = 25.4 Ω

Equivalent Resistance (Rₑq) =?

Rₑq = R₁ₙ₃ + R₂ (series connection)

Rₑq = 25.6 + 25.4

Rₑq = 51 Ω

Therefore, the equivalent resistance of the group is 51 Ω.

Justin mixed two cups of lemon juice and two cups of sugar with a gallon of water in a pitcher. What happened to the lemon juice, sugar, and water?

Answers

Answer:

The correct answer is - Lemon juice hydrolyzes sugar and dissolves it faster and creates a solution.

Explanation:

When mixing lemon juice and sugar in water are mixed together, the lemon juice dissolves the sugar faster as it has citric acid that hydrolyzes sucrose molecules of sugar in glucose and fructose.

This mixing of all three lemon juice, water, and sugar form a solution. Here in this solution, water is solvent, and sugar and lemon juice are solutes. The quantity of all three determined the nature of the solution if it will be acidic or more diluted.

Answers

Answer:

the Input Energy  is 1,100 J

Explanation:

Given;

useful energy, = 1000 J

energy wasted, = 100 J

The total or input energy is given as;

Input Energy = useful energy + energy wasted

Input Energy = 1000 J   +   100 J

Input Energy = 1,100 J

Therefore, the Input Energy  is 1,100 J

First, evaluate these three models. One represents fission, one fusion, and one radioactive decay. Write three sentences about each one according to the following framework:
---State what reaction the model represents, including what it demonstrates about mass and/or energy.
---State whether you think the model accurately represents the reaction. Explain why or why not.
---Suggest one way to improve the model.


Model A: Two sponge balls representing two atoms are soaked in water. You hold one ball, and your friend holds the other. Then you press the two balls together. As you press them together, water leaks out. What type of reaction does this model represent?



Model B: You draw a tree diagram showing a large atom splitting into two parts and neutrons being released. Your diagram also shows the released neutrons hitting other large atoms, which then each split in two and release more neutrons, which hit more large atoms, and so on. What type of reaction does this model represent?



Model C: You have 100 candies with the letter "M" on one side. You pour the candies into a pan. You count and remove all the candies with the "M" facing upward. Then you shake the pan and again count and remove all the candies with "M" facing upward. You shake, count, and remove candies four more times. What type of reaction does this model represent?

Answers

When energy is transferred from system to surrounding then the corresponding reaction known as exothermic reaction in Modle A when we press the ball(atom) the water(energy) is transferred into surrounding hence it is an exothermic reaction.

When a single atom disintegrate to give two or more atom with radioactive substance then the corresponding reaction know as Nuclear Fission reaction. hence Modle B represents Nuclear fission reaction.

The Model C represents Radioactive decay, So in the given example or model the water is playing role of radiation through which we are removing the candies having M on upside.

in 4 seconds, a cheetah can run 112 meters. How fast does this cheetah have to be running? A: 448 m/s || B: 28 m/s || C: 56 m/s || D: 36 m/s​

Answers

Answer:

B: 28m/s

Explanation:

Use the speed formula

Speed =distance / time

Answer:

[tex]\boxed {\boxed {\sf B. \ 28 \ m/s}}[/tex]

Explanation:

If we want to know how fast the cheetah is running, we need to calculate its speed. This is the rate at which an object moves and the formula is distance divided by time.

[tex]s=\frac{d}{t}[/tex]

The cheetah ran 112 meters in 4 seconds.

d= 112 m t= 4 s

Substitute the values into the formula.

[tex]s=\frac{112 \ m}{ 4\ s}[/tex]

Divide.

[tex]s= 28 \ m/s[/tex]

The cheetah's speed is 28 meters per second and choice B is correct.

Draw a circuit that uses the resistors listed below as well as a 12V battery source. For your circuit, determine (a) the total resistance, (b) the total current, and (c) the total voltage over the entire system.

Answers

Answer: hello your questions lacks the required resistor values therefore i will provide a general answer using an example

answer : a) 14 ohms  b) 0.86 amps   c) 10.32 V

Explanation:

Assuming the resistors are : 3 ohms , 4 ohms and 5 ohms

Voltage source = 12V

Assuming that the Resistors are in series

a) Determine Total resistance

Req = R1 + R2 + R3

       = 3 + 4 + 5 = 14 ohms

b) Total current

Ieq = V / Req

      = 12 / 14 =  0.86 amps

c) The Total Voltage over the entire system

Vt = ∑ Voltage drops

    = ( 0.86 * 3 ) + ( 0.86 * 4 ) + ( 0.86 * 5 )

    = 10.32 V

a snail is at rest. it accelerates at a rate of 0.0075m/s^2. calculate the time it takes to reach a speed of 0.0135m/s​

Answers

Answer:

1.8 seconds

Explanation:

Initial velocity (u) = 0 m/s

[Since, it is at rest. ]

Acceleration (a) = 0.0075 m/s²Final velocity (v) = 0.0135 m/s²

We are asked to calculate time taken to reach a speed of 0.0135m/s.

By using the first equation of motion,

→ v = u + at

v denotes final velocityu denotes initial velocitya denotes accelerationt denotes time taken

Substituting values,

→ 0.0135 = 0 + 0.0075t

→ 0.0135 = 0.0075t

→ 0.0135 ÷ 0.0075 = t

→ 1350000 ÷ 750000 = t

→ 135 ÷ 75 = t

→ 1.8 = t

→ Time taken = 1.8 seconds

Therefore, it takes 1.8 seconds to reach a speed of 0.0135m/s.

Answers

Answer:

Explanation:

The extra helium got into the universe through big bang and fusion reaction that occur in stars. Our universe formed about 13.7 billion years ago with big explosion, this event is known as big bang. The fusion of hydrogen nuclei in the stars produces helium and energy so we can say that most of the extra helium got into the universe through fusion reaction that occur in the stars continuously.

Answers

Find answers below

Explanation:

Mathematically, force is given by the formula;

Force = mass * acceleration

Given the following data;

6. Mass = 8 kg

Acceleration = 2 m/s²

Force = 8 * 2

Force = 16 Newton

7. Mass = 5 kg

Acceleration = 2 m/s²

Force = 5 * 2

Force = 10 Newton

8. Mass = 8 kg

Acceleration = 8 m/s²

Force = 8 * 8

Force = 64 Newton

9. Mass = 200 kg

Acceleration = 3 m/s²

Force = 200 * 3

Force = 600 Newton

speed of 27 m/s. What is the acceleration of the roller coaster? **Round to
1 decimal place**

Answers

Answer:

Acceleration = 3.67 m/s²

Explanation:

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]

Given the following data;

Initial velocity, u = 5 m/s

Final velocity, v = 27

Time, t = 6

To find the acceleration;

Acceleration = (v - u)/t

Acceleration = (27 - 5)/6

Acceleration = 22/6

Acceleration = 3.67 m/s²
