Answers
Answer:
The work-energy theorem says the following
Wnet = ΔE
Wnet = Ef - Ei
Therefore, the net work is equal to the difference between the final energy and the initial energy.
It can be rewritten as:
Ei + Wnet = Ef
So, it looks like the equation for the conservation of energy (Ei = Ef) but it adds the term for the net work (Wnet) on the left side of the equation.

The magnitude of the power dissipated in resistor R4 is approximately 10,028 watts.
How to find magnitude?To find the power dissipated in resistor R4, use the formula:
P = I² × R
where P = power, I = current flowing through the resistor, and R = resistance of the resistor.
The total resistance, Rt, can be calculated using the formula:
1/Rt = 1/R1 + 1/R2 + 1/R3
Substituting the given values:
1/Rt = 1/3 + 1/0.8 + 1/2
Simplifying the equation:
1/Rt ≈ 1.6667
Rt ≈ 0.6 Ω
Next, calculate the total voltage, Vt, by summing the individual voltage sources:
Vt = ε1 + ε2 + ε3
Substituting the given values:
Vt = 9 + 6 + 4
Vt = 19 V
Now calculate the current flowing through resistor R4 using Ohm's Law:
I = Vt / Rt
Substituting the calculated values:
I = 19 / 0.6
I ≈ 31.6667 A
Finally, calculate the power dissipated in resistor R4:
P = I² × R4
Substituting the calculated values:
P = (31.6667)² × 10
P ≈ 10,028 W
Therefore, the magnitude of the power dissipated in resistor R4 is approximately 10,028 watts.

30 Ω
[?] volts
Answers
24 volts is the voltage drop across each of the resistors in the parallel configuration.
When resistors are connected in parallel, they share the same voltage across them. Therefore, the voltage drop across each resistor in this scenario would be the same.
Given:
Power supply voltage (V) = 12 V
Resistance of each resistor (R) = 30 Ω
Since the resistors are in parallel, the total resistance (R_total) can be calculated using the formula:
1/R_total = 1/R1 + 1/R2
Substituting the values:
1/R_total = 1/30 Ω + 1/30 Ω
1/R_total = 2/30 Ω
R_total = 15 Ω
Now, we can find the current flowing through the resistors (I) using Ohm's Law:
I = V / R_total
I = 12 V / 15 Ω
I = 0.8 A
Since the voltage drop across each resistor is the same, we can find it using Ohm's Law:
V_drop = I * R
V_drop = 0.8 A * 30 Ω
V_drop = 24 V
Therefore, the voltage drop across each of the resistors in the parallel configuration is 24 volts.

Answers
Answer:
Natural selection.
Explanation:
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.
On the other hand, artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.

Monochromatic light passes through two narrow slits 0.23 mm apart and forms an interference pattern on a screen 2.17 m away. If light of wavelength 611.17 nm is used, what is the distance from the center of the central maximum to the center of the third order bright fringe in centimeters?
Answers
Firstly, for us to solve this problem, we must remember that the distance between each maximum can be written as:
\(\Delta y_{max}=\frac{D\lambda}{d}\)Where D is the distance from the slit to the screen, d is the distance between each slit and lambda is the wavelength. Thus, we can calculate this as:
\(\Delta y_{max}=\frac{2.17*611.17*10^{-9}}{0.23*10^{-3}}=5.766mm\)Thus, the distance from the central max (y0) and third max (y3) is three times this distance:
\(\Delta_{y0y3}=3*\Delta y_{max}=3*5.766mm=17.2988mm\)Then, our final answer is delta=1.73cm
A radio is rated as 50 W. Calculate the energy transferred in Joules by the radio when it has been switched on for 2 minutes?
Answers
The energy transferred in Joules by the radio when it has been switched on for 2 minutes would be 6000 Joules.
Energy transferPower is defined as the rate of energy transfer or the rate at which work is done, and is given by the equation:
Power = Energy transferred / Time
Rearranging the equation to solve for energy transferred, we get:
Energy transferred = Power x Time
We are given:
Power = 50 W
Time = 2 minutes = 120 seconds
Therefore, the energy transferred by the radio when it has been switched on for 2 minutes is:
Energy transferred = Power x Time = 50 W x 120 s = 6000 J

The magnetic field vector B⃗ 1
at point 1 has the magnitude of 1.3 nT
and points out of the figure. What are the magnetic field vectors B⃗ 2
through B⃗ 5
at points 2 through 5 due to the moving charge in (Figure 1)?
Answers
The magnetic field vectors at points 2 through 5 due to the moving charge are B₂ = -1.3 x 10⁻⁹ T into the paper, B₃ = 0, B₄ = 0, and B₅ = 1.3 x 10⁻⁹ T out of the paper.
What are the magnitude of the field vectors?
To determine the magnetic field vectors B₂ through B₅ at points 2 through 5 due to the moving charge, we need to use the Biot-Savart Law. The Biot-Savart Law gives the magnetic field at a point due to a current-carrying wire or a moving charge.
The Biot-Savart Law is given by:
dB = μ₀/4π (I x dℓ x ẑ) / r²
where;
μ₀ is the permeability of free spaceI is the current, dℓ is the infinitesimal length element of the wire,r is the distance between the element and the point at which we are calculating the field, and ẑ is a unit vector in the direction of the current.Considering the velocity of the charge, the magnetic field at each point:
B₂ = μ₀/4π (q vᵧ / r²)sin(90°) = μ₀/4π(q vᵧ / r²)
B₃ = μ₀/4π (q vᵧ / r²)sin(180°) = 0
B₄ = μ₀/4π(q vᵧ / r²)sin(180°) = 0
B₅ = μ₀/4π(q vᵧ / r²)sin(90°) = μ₀/4π(q vᵧ / r²)
where;
r is the distance between the moving charge and each point (2, 3, 4, 5).Using the given distance of 1.0 mm, we can calculate the magnetic field magnitudes at each point:
B₂ = μ₀/4π(q vᵧ / r²)
The velocity of the charge is calculated as;
B₁ = μ₀/4π(q vᵧ / r²)
1.3 x 10⁻⁹ = (1.26 x 10⁻⁶ Tm/A)/4π)(1.6 x 10⁻¹⁹ C)(v)/(0.001)²
v = 1.02 x 10⁵ m/s
B₂ = (1.26 x 10⁻⁶ Tm/A)/4π)(1.6 x 10⁻¹⁹ C)(1.02 x 10⁵ m/s) / (0.001 m)²
B₂ = 1.3 x 10⁻⁹ T
B₃ = 0 (since sin(180°) = 0)
B₄ = 0 (since sin(180°) = 0)
B₅ = μ₀/4π(q vᵧ / r²)
B₅ = (1.26 x 10⁻⁶ Tm/A)/4π)(1.6 x 10⁻¹⁹ C)(1.02 x 10⁵ m/s) / (0.001 m)²

This question involves the concept of the law of conservation of energy.
The potential energy at A,B,C is "9.6 J","3.2 KJ","0 KJ", respectively.
The kinetic energy at A,B,C is "0 KJ","6.4 KJ","9.6 KJ", respectively.
What is the law of conservation of energy?The law of conservation of energy states that total energy of the system at any instant must remain constant.
At point AAt point A, the rider is at rest at a height of 48 m on top of the slide. So the kinetic energy of the rider must be 0 KJ. And the potential energy will be given as follows:
\(P.E=mgh\)
where,
P.E = potential energy = ?m = mass = 20 kgg = 10 m/s²h = height = 48 mTherefore,
\(P.E = (20\ kg)(10\ m/s^2)(48\ m)\\\)
P.E = 9600 J = 9.6 KJ
At point B
The potential energy at point B will be:
\(P.E=mgh\)
where,
P.E = potential energy = ?m = mass = 20 kgg = 10 m/s²h = height = 16 mTherefore,
\(P.E = (20\ kg)(10\ m/s^2)(16\ m)\\\)
P.E = 3200 J = 3.2 KJ
According to the law of conservation of energy the rest of the total energy shall be converted to kinetic energy:
K.E = 9.6 KJ - 3.2 KJ

Advantages of Surface tension are -
It gathers water into a ball.
It permits a distinct boundary layer that is similar to a non-Newtonian liquid.
It enables water to rise into a paintbrush through capillary action.
It permits rain to fall as drops as opposed to a stifling mass.
It enables smooth surfaces to form as concrete and liquid metals solidify.
Disadvantages of Surface tension are -
The behavior of water would alter if surface tension were eliminated, some of these changes being related to surface tension's drawbacks. Washing clothing is one example that is close to home. Detergent is required while washing garments due to the comparatively high surface tension of water. Reduced surface tension enables laundry water to fully permeate the garments for better cleaning as part of the task of laundry detergent. It would take far less detergent to wash clothes if water had a naturally low surface tension.
When you want to create a fine water spray, such as with a lawn sprinkler, surface tension again becomes an issue. Surface tension makes it harder to divide water into tiny droplets. Sprinklers could operate on a hose with less pressure if they were used with water that had a lower surface tension.
What is a surface tension ?
Surface tension is the propensity for liquid surfaces that are at rest to condense into the smallest surface area. Razor blades and insects (like water striders), which have a higher density than water, can float on the surface of the water without even becoming partially buried because to surface tension.
Surface tension at liquid-air contacts originates from the liquid molecules' stronger attraction to one another due to cohesion than to the air molecules (due to adhesion).
There are primarily two mechanisms at work. One causes the liquid to constrict by exerting an inward push on the surface molecules. The second force is tangential and parallel to the liquid's surface. The surface tension is the common name for this tangential force.
Overall, the liquid acts as though an elastic membrane was stretched over its surface. However, this comparison should not be drawn too far because surface tension is a characteristic of liquid-air or liquid-vapor interfaces, but the tension in an elastic membrane depends on how much it is deformed.

Reduced surface tension enables laundry water to fully permeate the garments for better cleaning as part of the task of laundry detergent. It would take far less detergent to wash clothes if water had a naturally low surface tension.
When you want to create a fine water spray, such as with a lawn sprinkler, surface tension again becomes an issue. Surface tension makes it harder to divide water into tiny droplets. Sprinklers could operate on a hose with less pressure if they were used with water that had a lower surface tension.
