WILL AWARD BEST ANSWER! find the current flowing across the 30 ohm resistor
i = _ a
Answers
0.143 A
Explanation:
The total resistance of the circuit is
[tex]r = \frac{(40)(30)}{40 + 30} + \frac{(50)(20 + 10)}{50 + (20 + 10)} \\ = 35.89 \: ohms[/tex]
so the total current is
Itotal= V/R = 9V/35.89 ohms
= 0.25 A
To find the voltage drop across the 30-ohns resistor, use
V = Itotal × (combined resistance of 40 30)
= 0.25 A × 17.14 ohms = 4.285 volts
so the current through the 30-ohm resistor is
I = (voltage drop)/30-ohms
= (4.285 V)/(30 ohms)
= 0.143 A
For a parallel circuit the voltage across each resistor is the same. Therefore, the voltage drop across the 30 Ω resistor is 9V. Then, the current through this resistor is 0.3 A.
What is resistance ?Resistance is the hindrance to the flow of current through a circuit. It is expressed in Ohms. Resistance and current are in inverse proportion. According to Ohm's law, the product of current and resistance is the voltage across the circuit.
V = I R
There are two type of circuits parallel and series. Parallel circuits connects each components in parallel fashion where, the current through each one will be different and voltage is constant.
In a series circuit, the voltage drop across each component is different but the current is the same.
Here, the resistors are connected in a parallel fashion. Hence the voltage drop across each resistors will be 9 V itself.
then current across 30 Ω resistor is:
I = V/R
= 9 v/ 30 Ω
= 0.3 A.
Therefore, the current through the resistor of 30 Ω is 0.3 A.

A force of 12 N is applied to a ball which has a mass of 6 kg. What is the acceleration of the ball?
Answers
Answer:
The acceleration of the bowling ball is
1.875 m/s2
1.875 m/s^2
Explanation:
The formula we will use is based off of Newton's Second Law is FNET= ma Where:
=> the net force is in Newtons (N).
=> m is mass in kilograms (kg).
=> a is acceleration in m/s^2
The FA is 12N [forward], therefore we know the net force is not 0. Normally, FF is considered, but we do not have enough information to calculate it, so we will assume a frictionless problem.
If the only force is the applied force, then the net force is 12N. Knowing this and the mass, we can isolate and solve for a.
FNET = ma
12=6.4a
1.875=a
ANSWER = Therefore, the acceleration of the bowling ball is 1.875 m/s^2

The equivalent resistance is 14.5 ohms
We need to find the value of R₂.
When two resistors are connected in parallel. The equivalent resistance is given by :
[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}\\\\\dfrac{1}{14.5}=\dfrac{1}{35}+\dfrac{1}{R_2}\\\\\dfrac{1}{R_2}=\dfrac{1}{14.5}-\dfrac{1}{35}\\\\\dfrac{1}{R_2}=0.04039\\\\R_2=\dfrac{1}{0.04039}\\\\R_2=24.75\ \Omega[/tex]
So, the value of R₂ is equal to 24.75 ohms.

How high should a box of mass 20kg is lifted to store energy of 10,000 J? (g=10m/s)
Answers
Answer:
Height, h = 50 meters.
Explanation:
Given the following data;
Mass = 20kg
Potential energy = 10,000 J
Acceleration due to gravity, g = 10m/s²
To find the height of the box;
Potential energy can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
[tex] P.E = mgh[/tex]
Where,
P.E represents potential energy measured in Joules.m represents the mass of an object. g represents acceleration due to gravity measured in meters per seconds square. h represents the height measured in meters.Substituting into the formula, we have;
10000 = 20*10*h
10000 = 200h
Height, h = 10000/200
Height, h = 50 meters.

Develop a Model to Show the Release or Absorption of Energy from a Chemical Reaction System
In this project, you will develop a model of a chemical reaction that either releases energy or absorbs energy. Whether a reaction releases or absorbs energy depends on the overall difference in the bond energies of the reactants and products. Your model should show the relationships between the parts of the system. These parts are the molecules and atoms that take part in the reaction. The model should also distinguish the reaction system from other systems.
Background
Atoms are the basic units of the types of matter known as elements. Very few elements exist in nature as single atoms. Most elements exist as atoms joined together into compounds by chemical bonds. During a chemical reaction, bonds are broken, atoms are rearranged, and new substances with new bonds form. Energy must be absorbed in order to break bonds, and energy is released when bonds form.
For any given compound, the amount of energy that will break its bonds and the amount released when the same bonds form are the same. For example, 1 mole of water molecules must absorb 1,840 kJ of energy for its bonds to break. And, when 1 mole of new water molecules form, the same amount of energy (1,840 kJ) is released. The amount of energy needed to break or form
1 mole of a certain type of bond is called bond energy.
As a reaction proceeds, the total bond energy of the reaction system changes. The total change in the bond energy depends on two factors:
1) the energy absorbed by the initial molecules (reactants) in order to break their bonds, and
2) the energy released as the bonds in the molecules that result (products) form.
For example, if breaking the reactants' bonds requires less energy than is released as the bonds of the products form, then the chemical reaction releases energy. This is what the graph on the left below shows. A chemical reaction that releases energy overall is called an exothermic reaction. If breaking the reactants' bonds requires more energy than is released as the bonds of the products form, then the chemical reaction absorbs energy. This is what the graph on the right below shows. A chemical reaction that absorbs energy overall is called an endothermic reaction.
The graph on the left shows a reaction system whose bond energy decreases. The graph on the right shows a system whose bond energy increases. So, the overall difference in the bond energies of the reactants and products determines whether the system absorbs or releases energy overall.
You will need to work with your teacher to develop your model. You can model either an exothermic reaction or an endothermic reaction. Materials needed should be readily available to you. After plans for your model are approved, you will need to build and use your model. This will enable you to determine how well your model works. You should then make changes, if necessary so that your model more accurately describes the chemical reaction system.
Part I: Develop a Plan for Your Model (20 points)
1. Research atoms, chemical bonds, chemical reactions, and molecules. As part of your research, find ways that other people have modeled chemical reactions. Summarize your research. Use your summary to develop a plan to create a model showing that the release or absorption of energy from a chemical reaction system depends on the changes in total bond energy. (13 points)
2. Write a brief description of the project you will do. Your description should include these parts: (7 points)
- A descriptive title
- An introduction that describes models and what they are being used for in this project
- A review of scientific research related to your topic
- A step-by-step procedure that describes the methods and materials for developing and using the model
- Any limitations of your model
- A description of how you will evaluate your model

2. Lithium ion battery provides energy through chemical reaction. Inside the battery, Lithium metal loses an electron as it reacts with acid and forms a Lithium salt solution. The total bond energy of Lithium salt is less than the Lithium metal with its electron. So energy is given out as electricity and heat. The chemical reaction is an exothermic reaction.
By connecting the battery to a music player, the battery will power up the player, turning electricity into sound energy.

A 80 kg person buys a scale at a mall that reads weight in Newtons and can’t wait to try it out, so they open the scale on an elevator. What would the scale read if the elevator was moving upward at 6.2 m/s2?
Answers
Answer:
The scale read 1280 N.
Explanation:
Given that,
The mass of a person, m = 80 kg
We need to find the scale reading when the elevator is moving upward at 6.2 m/s².
We know that, when an elevator moves up, the reading on the scale is given by :
N-mg=ma
N=m(a+g)
Put all the values,
N = 80(6.2+9.8)
= 80(16)
= 1280 N
Hence, the scale read 1280 N.

Explanation:
In the equation energy E = h X v
The "h" there signifies Planck's constant
Planck's constant is a value, that shows the rate at which the energy of a photon increases/decreases, as the frequency of its electromagnetic wave changes.
It was named after Max Planck who discovered this unique relationship between the energy of a light wave and its frequency.
Planck's constant, "h" is usually expressed in Joules second

22) Net force is the total of all forces acting on an object. When a force is balanced and the object does not move, the net force is equal to what: A) 0 B) 10 C) 100 D) The weight of the object
Answers
Answer:
A) but be sure and read the answer.
Explanation:
If the object does not move at all, (that's an important restriction) the net force = 0. That being so, the acceleration must be 0 as well. But there is no law saying that there cannot be a constant motion and that's why the restriction is important.
