R1+R2+R3 =1+1+1=3 is used to represent the circuit's overall resistance.
The 3 resistors on the upper side of the circuit are linked in series in this instance, and the total resistance R1 is expressed as 1+1+1=3.
The combined resistance R2 is expressed as 2+2+2=6 due to the series connection of the three 2-ohm resistors on the lower part of the circuit. The intermediate resistances R1, R2, and 2 are linked in parallel. This parallel connection's total resistance, R3, is therefore represented as 2/1+ 2/1+ 6/1 = 1/1=1 ohm.
In other words, the closed loop's resistance is decreased to 1 ohm.
Now, R1+R2+R3 =1+1+1=3 is used to represent the circuit's overall resistance (R).
As a result, the resistance in the circuit from point A to point B is 3.

A solid block of metal is at its melting temperature. it takes 24j to melt 6kg of a metal. what is the latent heat of fusion of the metal?
The Latent heat of fusion is also known as the Enthalpy of Fusion. It is a kind pf change in enthalpy.
Brief explanation of Latent Heat of Fusion?The latent heat of fusion, is the change in enthalpy that takes place when energy, typically heat, is provided to a specific quantity of a substance to causes it to change from a solid state to a liquid state at a constant pressure.
For instance, 1 kilogram of ice melts at 0 °C at a variety of pressures, absorbing 333.55 kJ of energy without causing a change in temperature.
The heat of solidification, which occurs when a substance changes from a liquid to a solid, is equal and opposing.
This energy includes the contribution necessary to displace its surroundings against ambient pressure in order to accommodate any corresponding change in volume.
The melting point or the freezing point, depending on the situation, is the temperature at which the phase transition takes place. Conventionally, unless otherwise stated, the pressure is taken to be 1 atm (101.325 kPa).
CalculationThe formula of latent heat of fusion is L= q/m
Here q is the heat provided and m is the mass of the object.
So, L = 24j/6kg
L= 4j/kg
So, the latent heat of fusion is 4 j/kg

A resistor carries 0.40 a when connected to a 9.0-v battery. what is theresistance of the resistor?
The resistance of the resistor which carries 0.40 a when connected to a 9.0-v battery is 22.5 ohm
Given:
current of resistor = 0.40 A
voltage of resistor = 9.0 V
To Find:
the resistance of the resistor
Solution: Resistance of a resistor with current I and voltage V is defined as the ability of the element to resist the flow of current through it. It's SI unit is V/A or ohm. Ohms () are used to express resistance values. Electricity will flow from high to low when two terminals have an electron difference. That flow is countered by resistance. The current decreases as resistance increases. Conversely, the higher the current, the lower the resistance.
Voltage = Current x Resistance
Resistance = Voltage/Current
Resistance = 9 V/0.40 A = 22.5 ohm
Hence, the resistance of the resistor is 22.5 ohm

What is the acceleration of a 10 kg mass pushed 5 n forceushed by a 5n(kg-m/s2) (use gresa method)
The final acceleration of the object is 2 m/[tex]s^{2}[/tex].
In this problem,
Applied force(F) = 10 N
The object’s mass (m) is 5 kg.
Having said that,
An object’s force is equal to the product of its mass and the acceleration it experiences as a result of the applied force.
i.e., Mass + Acceleration = Force (a)
F= m×a
Therefore,
A= F÷m
A= (10÷5) m/sec²
A= 2 m/sec²
Consequently, the object’s acceleration,
A=2 m/sec²
Concept of force and acceleration:
This states that the rate of velocity change of an object is directly proportional to the applied force and moves in the direction of the applied force.
It can be expressed mathematically as force (N) = mass (kg) x acceleration (m/s2). Therefore, an object with constant mass will accelerate in direct proportion to the applied force.

A battery is discharging. electric current exits the battery through the ______ terminal, at a ______ potential than when it entered
When a battery discharges the current exits through the positive terminal at a higher potential than it entered.
When a battery discharges the current exits the battery through the positive terminal as a circuit connected to that should conduct current from positive to a negative potential.Accordingly, the current enters the battery at its negative terminal.In practicality, batteries contain some internal resistance that restricts the current flow during current flow.That is why there is a potential difference between the 2 terminals.To drive the current through the external circuit connected to the battery, it keeps a higher potential at its positive terminal while the negative terminal is kept at a lower potential in contrast.#SPJ4

Gases at pressure are released by rockets as they travel towards space. According to Newton's third law, the combustion chamber's exhaust gases push the rocket with an accelerating force known as the thrust.
Explain exactly Newton's Third Law:According to Newton's third law, if an object A pulls on an object B, then object B must exert an equal-sized and opposite-direction force on the first thing directed in the opposite direction. This law illustrates a symmetry in nature whereby forces always occur in pairs and whereby no body can exert a force without also being subjected to one.

Why is sugar solution classified the way it is?
Why would you have to know how to convert measurements when looking at a technical drawing?
1.) When examining technical drawings, conversion of dimensions is crucial knowledge to have. A person with measurement skills may use an object's shape to determine its sides, angles, area, and volume. If he is aware of these factors, he will be able to modify a sketch or design if the need arises.
If someone knows how to convert a measurement to a system that the other person is familiar with, they can do so when working with someone who is unfamiliar with the measuring system.
2.) Units have a crucial role. No meaning is given to numbers without units in scientific computations. For instance, if someone asks a shopkeeper for three rice, the shopkeeper may not grasp what he means, but if he is told that the customer wants three kilograms of rice, the shopkeeper will. Because the value of anything in one system of units may differ from that of the other, you need also be familiar with unit conversion into other systems (Metric, SI). Understanding units in this way can help with numerous issues.
An object or event's attributes are quantified through measurement so that they can be compared to those of other things or occurrences. Therefore, measurement is the process of determining the size or smallness of a physical quantity in relation to a primary reference quantity of a similar kind. The act or system of measuring is referred to as measurement. It can be viewed as a procedure for utilizing numbers to define physical objects.
