The loss of voltage brought on by the passage of current through a resistance is known as voltage drop.
What is Voltage Drop?The cable's resistance and reactance grow proportionately with its length. This means that VD is a problem that is especially prevalent where there are long cable runs, such as in large buildings or on expansive properties like farms. In any single phase, line to line electrical circuit, this technique is frequently used to size conductors properly. Use a voltage drop calculator to determine this.Current flowing through electrical cables is always impeded or met with resistance. VD is defined as the voltage loss (in volts) caused by cable "impedance" that occurs throughout all or a portion of a circuit.Insufficient VD can result in lights that flicker or burn dimly, heaters that heat inefficiently, and motors that run hotter than necessary and eventually burn out. In this situation, less voltage is pushing the current, which makes the load work harder.To Learn more About voltage drop refer to:

The silver wire will be longer than the copper wire as the silver has the high expandability than the copper and not just that the silver is very good conductor for electricity but we use copper for wires cause of there cheap availability.
what is resistance?
The amount that an object impedes or resists in an electric current is referred to as resistance. Electric current is the flow of electrons. Consider an example of a person attempting to move from one shop to another in a busy market. This condition is eerily similar to an electron attempting to pass through a wire.
Resistance is the property of materials that allows electric current to flow. Resistance unquestionably resists the passage of current. Furthermore, the unit of resistance is ohms, which is symbolised by the Greek capital letter omega.

In the reaction shown, iron reacts with water to form iron oxide (Fe3O4) and hydrogen gas (H₂).
3Fe + 4H₂0
Fe3O4 + 4H₂
Which of these BEST describes the iron (Fe) reactant?
A. molecule
B. ion
C. compound
D. Element
Cold water does not react with iron. Iron, however, interacts with steam to create iron and hydrogen oxide. Fe3O4 + 4H2 = 3Fe(s) + 4H2O. Iron (II, III) oxide, also known as ferric oxide (Fe3O4), is a combination of Fe O and Fe2O3.
What happens when water and iron are combined?Ferric oxide (Fe2O3) and hydrogen gas are produced when ferrous oxide (Fe O) and water (H2O) combine (H2). This reaction yields a black solid called Fe3O4, which is frequently used as an antirust pigment. Understanding the chemical equation for this reaction is required to determine whether a specific mixture will produce Fe3O4: 2Fe3+(aq)+3H2 = 2Fe(s)+3H2(g) (g). According to this equation, two moles of iron metal will interact with to create two moles of ferric ion and three moles of hydrogen gas, it takes three moles of hydrogen gas. All of the iron will be transformed to Fe3+ ions and no Fe3O4 will occur if the combination only contains one mole of each component.

What is the Roche limit of Earth?
Solar influence
Far from the Roche limit, the mass is practically spherical. Closer to the Roche limit, the body is deformed by tidal forces. Within the Roche limit, the mass's own gravity can no longer withstand the tidal forces, and the body disintegrates.If Earth had two moons, it would be catastrophic. An extra moon would lead to larger tides and wipe out major cities like New York and Singapore. The extra pull of the moons would also slow down the Earth's rotation, causing the day to get longer.The Moon will swing ever closer to Earth until it reaches a point 11,470 miles (18,470 kilometers) above our planet, a point termed the Roche limit. "Reaching the Roche limit means that the gravity holding it [the Moon] together is weaker than the tidal forces acting to pull it apart," Wilson said.The Roche limit for the Moon orbiting the Earth is 2.86 times radius of EarthThe nearest distance between the planet and its satellite at where the planets gravitational pull does not torn apart the planets satellite is known as Roche limit.The relation to determine Roche limit is:

Using the concepts of work, we got that 0 joule is the amount of the work done during the process in which 1.2-m3 rigid tank contains nitrogen gas at 200 kpa and 350 k and heat is transferred to the nitrogen in the tank and the pressure of nitrogen rises to 900 kpa.
We are given some values of the rigid tank which are
Volume of the tank (V) = 1.2 m³
Initial pressure of the nitrogen (P₁) = 200 kPa
Initial temperature of the nitrogen (T₁) = 350 K
Final pressure of the nitrogen (P₂) = 900 kPa
The volume of nitrogen gas is same as volume of tank. Now, as the tank is rigid so, the volume of nitrogen gas remains the same.
We know that,
Work done on a gas is given as: PΔV
Where, ΔV is the change in volume.
But, the volume here is constant. So, ΔV = 0.
Therefore, work done=P×0=0Joules.
Hence, if 1. 2-m3 rigid tank contains nitrogen gas at 200 kpa and 350 k and Heat is transferred to the nitrogen in the tank and the pressure of nitrogen rises to 900 kpa, then the work done during this process is 0 joules.

Acceleration will be zero when there is no movement. The coefficient of static friction is 0.6
What is Friction ?Friction is a force that opposes motion. It is static in a stationary object while dynamic in a moving object.
Given that Block A has a mass of 10 kg and block B has a mass of
6 kg. They are connected by a rope and pulley system as shown in the diagram in the question. Since both blocks are not moving, acceleration a = 0
The weight W on block B = mg
