Explanation:
I don't know if you answered your own question but I'll just answer this for others confused ahh
As the average kinetic energy of a substance increases, its thermal energy increases which increases the temperature, and as the temperature increases, the internal energy of the substance increases.
The thermal energy, internal energy and kinetic energy of a gas are interrelated.
The average kinetic energy of a gas is its internal energy presented by the equation E = \(\frac{3}{2}k_{b}T\), here \(k_{b}\) is Boltzmann's constant and T is the temperature of the gas.We can see that the average kinetic energy of the internal energy is directly proportional to temperature.So if the thermal energy of the gas is increased, it raises the temperature of the gas, which will increase the vibrations of the molecules of the gas and the velocity of the molecules.The increase in the vibration of the molecules and their velocities results in increase in average kinetic energy and internal energy of the gas.Learn more about internal energy:

The wrecking ball swings along the wall between her house and the neighbor’s house. In an effort to determine the length of the cable on the wrecking ball the student builds a pendulum using a random rock and a string. Her pendulum turns out to be 0.500m long. While she plays with her pendulum she realizes that the wrecking ball swings back and forth in the same amount of time that it takes the rock to complete 5 full oscillations. What is the length of the cable on the wrecking ball?
Answers
Answer:
The length of cable is 12.5 m
Explanation:
Since, the wrecking ball completes 1 oscillation, in the same time, as it takes for the rock to complete 5 oscillations.
Therefore,
Time Period of Wrecking Ball = 5 (Time Period of Rock)
Since,
Time Period of Pendulum = 2π√(L/g)
Therefore,
2π√(L₁/g) = 5[2π√(L₂/g)]
√L₁ = 5√L₂
Squaring on both sides:
L₁ = 25 L₂
where,
L₁ = Length of Cable = ?
L₂ = Length of string = 0.5 m
Therefore,
L₁ = 25 (0.5 m)
L₁ = 12.5 m
A gas undergoes two processes. In the first, the volume remains constant at 0.170 m3 and the pressure increases from 1.50×105 Pa to 6.00×105 Pa . The second process is a compression to a volume of 0.130 m3 at a constant pressure of 6.00×105 Pa. Find the total work done by the gas during both processes.
Answers
Answer:
\(W_{T} = - 24 kJ \)
Explanation:
The work (W) done by the gas can be calculated using the following equation:
\( W = p*\Delta V = p*(V_{f} - V_{i}) \)
Where:
p: is the pressure
[tex}V_{f}\): is the final volume
[tex}V_{i}\): is the initial volume
In the first process, the work done by the gas is:
\( W_{1} = p*\Delta V = p*0 = 0 \)
Since the volume remains constant, the total work done by the gas is equal to zero.
In the second process, the work done by the gas is:
\( W_{2} = p*(V_{f} - V_{i}) = 6.00 \cdot 10^{5} Pa*(0.130 m^{3} - 0.170 m^{3}) = -24 kJ \)
Now, the total work done by the gas during both processes is:
\( W_{T} = W_{1} + W_{2} = 0 + (-24 kJ) = - 24 kJ \)
Therefore, the total work done by the gas during both processes is - 24 kJ.
I hope it helps you!
The total work done by the gas during both processes is 0 Joules and -2.4 × 10⁴ Joules respectively.
The work done on a system at constant pressure (P) can be expressed by using the relation:
W = ρdV
here:
dV = change in volume, and since the volume is said to remain constant in the first process, then V = (0)∴
W = ρ(0)
W = 0 Joules
In the second process;
V₂ = 0.130 m³V₁ = 0.170 m³Using the same relation;
W = ρdV
where
dV = (0.130 - 0.170) m³dV = - 0.04 m³∴
W = 6.00 × 10⁵ (-0.04) Joules
W = -24000 Joules
W = -2.4 × 10⁴ Joule

The magnitude of the resultant vector to round the answer to the nearest tenth, we look at the digit in the hundredth's place. If this digit is 5 or greater, we round up. If it is less than 5, we round down.
In the study of physics, we use vectors to represent quantities that have both direction and magnitude. It is often the case that we want to add two or more vectors together to obtain a single vector that represents the net result of these additions. The process of adding two or more vectors together is known as vector addition.The magnitude of the resultant vector is the length of the line that represents it on a scale drawing.
When we add two or more vectors together, the resultant vector is the vector that represents the net result of these additions. To find the magnitude of the resultant vector, we use the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
In the case of vector addition, the hypotenuse is the resultant vector, and the other two sides are the component vectors. If we have two vectors a and b, the magnitude of the resultant vector is given by the following equation:|R| = √(ax2 + bx2)where R is the resultant vector, a and b are the component vectors, and x is the angle between the vectors.

A small bag of sand is released from an ascending hot‑air balloon whose constant, upward velocity is 0=2.25 m/s . Knowing that at the time of the release the balloon was 35.8 m above the ground, determine the time it takes for the bag to reach the ground from the moment of its release. Use =9.81 m/s2.
Answers
The time that takes for a small bag of sand to reach the ground after it is released from an ascending hot-air balloon whose upward velocity is 2.25 m/s is 2.94 s.
We can find the time that takes for the bag to reach the ground with the following equation:
\( y_{f} = y_{i} + v_{i_{y}}t + \frac{1}{2}gt^{2} \) (1)
Where:
\( y_{f} \): is the final height = 35.8 m
\( y_{i} \): is the initial height = 0
\( v_{i_{y}} \): is the initial velocity = 2.25 m/s
t: is the time =?
g: is the acceleration due to gravity = 9.81 m/s²
When the bag is released, it will move upward until it reaches a maximum height and then begins to fall. We can find the time that takes for the bag to reach the maximum height as follows:
\( v_{f} = v_{i} - gt \) (2)
Where:
\( v_{f} \): is the final velocity = 0 (at the maximum height)
\( v_{i} \): is the initial velocity = 2.25 m/s
The time is:
\( t = -\frac{v_{f} - v_{i}}{g} = \frac{2.25 m/s}{9.81 m/s^{2}} = 0.23 s \)
This is the rise time it takes for the bag to reach the maximum height, which is equal to the fall time it takes for the bag to reach the same starting point (35.8 m above the ground), so:
\( t = 0.23 s*2 = 0.46 s \)
Now, from equation (1) we have:
\( 35.8 m = 0 + 2.25 m/s*t + \frac{1}{2}9.81 m/s^{2}*t^{2} \)
By solving the above quadratic equation for t we have:
\( t = 2.48 s \)
Hence, the total time is:
\( t = 2.48 s + 0.46 s = 2.94 s \)
Therefore, the time that it takes for the bag to reach the ground is 2.94 s.

Here are the details about the block- spring-Earth system:The block- spring-Earth system has minimum potential energy at point Y.
This statement is correct about the block- spring-Earth system. Let's explain this statement with some reasons. The system's gravitational potential energy is zero at point X, which is the lowest point of the center of mass of the block as it oscillates. At point Z, the highest point of the center of mass of the block as it ocillates, the gravitational potential energy of the block-spring-Earth system is maximum. The spring potential energy of the block-spring-Earth system is maximum at point Y, the equilibrium position of the block-spring system.Therefore, the block-spring-Earth system has minimum potential energy at point Y. In the absence of external forces and friction, total mechanical energy, which is the sum of the gravitational potential energy and the spring potential energy, should remain constant throughout the system's oscillation.

D) 11.2 A

E) 16 A
Answers
Answer:

Explanation:
The total resistance in the circuit is the resistances in parallel plus that in series.
Total resistance for those in parallel is;
1/(1/4 +1/6 +1/10) = 1/ (15+10+6 /60)
1/(31/60)= 60/31 ohms
Hence total resistance of the circuit is;
60/31 + 2 = (60+62)/31 = 122/31=3.94 ohms
To calculate the current flowing through the 10ohm resistance we need to know the voltage drop by subtracting the voltage drop in the 2ohm resistance from the total voltage drop.
Voltage drop on the 2 ohm resistance is;
Current on the 2 ohm resistor × 2 ohms
V = I ×R ; I - current
R - resistance
Current drop on the 2ohm resistance is;
Total voltage in the circuit/ total resistance in the circuit
12/3.94= 3.05A
Voltage drop on the 2 ohm resistance;
3.05 × 2 = 6.10volts
Hence voltage drop on the parallel resistance would be ;
12-6.10= 5.90V
Now voltage drop in a parallel circuit is the same hence 5.90v is dropped in each of the parallel resistance.
That said, the current drop on the 10 ohm resistor would be;
5.90/10 = 0.59A
Remember V= I× R so that I = V/R
The current flowing through the 10 ohms resistor is 0.59 A.
The given parameters;
resistors in parallel, = 4.0 Ω, 6.0 Ω, and 10.0 Ωresistor in series = 2 0 Ω,The equivalent resistance of the parallel resistors;
\(\frac{1}{R_e} = \frac{1}{4} + \frac{1}{6}+ \frac{1}{10} \\\\\frac{1}{R_e} = \frac{31}{60} \\\\R_e = \frac{60}{31} = 1.94 \ ohms\)
The overall resistance with series resistor
R = 1.94+ 2 = 3.94 ohms
The current flowing in the entire circuit is calculated as follows;
\(I = \frac{V}{R} \\\\I = \frac{12}{3.94} \\\\I =3.05 \ A\)
The voltage drop due to the 2 ohms resistor is calculated as follows;
V = 12 - 3.05(2)
V = 5.9 V
The current flowing in the 10 ohms resistor is calculated as follows;
\(I = \frac{5.9}{10} \\\\I = 0.59 \ A\)
Thus, the current flowing through the 10 ohms resistor is 0.59 A.

Light can act as a wave or a particle. This is called light wave-particle duality, simply that the light has both the characteristics of fluctuations, but also has the characteristics of particles. Light can propagate forward like a wave, and sometimes show the characteristics of particles.
Metal is not heat resistant and therefore it is not a good heat shield. For example pots are made out of metal because they are good conductors of heat.
Light is said to be the fastest, it is because we have not discovered anything faster than light. If someone discover's something faster than light then that will become the fastest. It is not that we have tried hard enough, it is just that our technology, research and veiw of outer space is limited. Implementing good research and technology requires a lot of money, time and expertise.

Answers
Robert has done 50,000 Joules of work in pushing the car 50 meters with a force of 1000 N
What is Work?Work is a measure of energy transfer that occurs when a force is applied to an object and causes it to move in the direction of the force.
Equation:To calculate the work done by Robert in pushing the car, we need to use the formula:
work = force x distance x cos(theta)
In this case, the force is 1000 N, the distance is 50 meters, and we assume that the force is applied parallel to the ground, so theta is 0 degrees. Therefore, cos(theta) is equal to 1.
Plugging in these values, we get:

A 1.2 kg ball drops vertically onto a floor hitting with a speed of 15 m/s
Answers
The magnitude of the change in momentum is 36 kg m/s.
The momentum of an object is defined as the product of its mass and velocity.
The symbol for momentum is p. Its unit is kilogram meters per second (kg m/s). When a ball falls vertically onto a surface, the momentum is said to change.
The magnitude of the change in momentum can be found by calculating the difference between the initial momentum and the final momentum.
We can use the equation below to find the change in momentum.Δp = pf - pi
Where Δp is the change in momentum, pf is the final momentum, and pi is the initial momentum.The initial momentum of the ball can be found using the equation:
p = mv
where p is momentum, m is mass and v is velocity.
Therefore, the initial momentum of the ball is:
p = mv= 1.2 kg × 15 m/s= 18 kg m/s
The final momentum can be found using the same equation, but with a negative velocity since the ball is bouncing back with the same speed but opposite direction.
Therefore, the final momentum is:-18 kg m/s/
The change in momentum can now be calculated using the equation:
Δp = pf - piΔp = (-18 kg m/s) - (18 kg m/s)Δp = -36 kg m/s
Therefore, the magnitude of the change in momentum is 36 kg m/s.

inquiry based pedagogy is being embraced in principle across the globe . in the last decade , it has been supported by an increasing body of research on its effectiveness . illustrate your understanding of the concept of inquiry based pedagogy with a relevant example.( 10 marks)
Answers
Inquiry-based pedagogy empowers students to explore, question, and construct knowledge through active engagement. It encourages curiosity, critical thinking, and independent investigation, fostering a deeper understanding of concepts and skills that extend beyond the classroom.
Inquiry-based pedagogy is an approach to teaching and learning that emphasizes the active engagement of students in the exploration of meaningful questions, problems, or phenomena. It encourages students to ask questions, investigate, and construct their own knowledge through critical thinking, problem-solving, and hands-on experiences. Here's an example to illustrate the concept of inquiry-based pedagogy:
Example: Exploring Ecosystems
In a biology class, the teacher introduces the topic of ecosystems using an inquiry-based approach. The teacher poses a driving question to the students: "How do living organisms interact with their environment to form ecosystems?"
1. Questioning and Investigation: Students begin by generating their own questions related to ecosystems. They might wonder about the roles of different organisms, energy flow, or the impact of human activities. Guided by their questions, they conduct research, gather information from various sources, and share their findings.
2. Hands-on Exploration: The teacher organizes hands-on activities to allow students to observe and explore ecosystems firsthand. For example, they could set up mini-ecosystems in terrariums or conduct field trips to local habitats. Through these experiences, students can make observations, collect data, and analyze patterns.
3. Collaborative Learning: Students work in groups or pairs to analyze the data they have collected and draw conclusions. They engage in discussions, share their ideas, and challenge each other's thinking. This collaborative learning environment promotes critical thinking, communication, and teamwork.
4. Reflection and Presentation: Students reflect on their findings and insights gained from their investigations. They are encouraged to synthesize their learning into presentations, reports, or visual representations. These presentations provide opportunities for students to articulate their understanding and demonstrate their learning outcomes.
By engaging in inquiry-based learning, students develop essential skills such as critical thinking, problem-solving, communication, and self-directed learning. They become active participants in their own education, taking ownership of their learning process and developing a deeper understanding of the subject matter.
