Wind direction is reported by the direction from which it originates. For example, a north or northerly wind blows from the north to the south. Wind direction is usually reported in cardinal (or compass) direction, or in degrees.

Answer:

3.7 L

Explanation:

Initial volume (V₁) = 3.3 L

Initial pressure (P₁) = 100 KPa

Final pressure (P₂) = 90 KPa

Final volume (V₂) =?

The final volume of the gas can be obtained by using the Boyle's law equation as follow:

P₁V₁ = P₂V₂

100 × 3.3 = 90 × V₂

330 = 90 × V₂

Divide both side by 90

V₂ = 330 / 90

V₂ = 3.7 L

Thus, the final volume of the gas is 3.7 L

Europium/Eu ( not really sure )

The lanthanide element with the least mass is Lutetium (Lu)

Lutetium (Lu) is a member of the lanthanide series, which is a group of 15 elements located in the f-block of the periodic table. The lanthanide series starts with the element Lanthanum (La) and ends with Lutetium (Lu). Lutetium is the heaviest and most dense element in the lanthanide series. Lutetium has an atomic number of 71, indicating that it has 71 protons in its nucleus. It has a relatively high atomic mass of approximately 174.97 atomic mass units (u) according to the periodic table.

Hence, lutetium is the lanthanide element with the least mass.

Answer:Resistor Basics

Resistors are electronic components which have a specific, never-changing electrical resistance. The resistor's resistance limits the flow of electrons through a circuit.

They are passive components, meaning they only consume power (and can't generate it). Resistors are usually added to circuits where they complement active components like op-amps, microcontrollers, and other integrated circuits. Commonly resistors are used to limit current, divide voltages, and pull-up I/O lines.

Resistor units

The electrical resistance of a resistor is measured in ohms. The symbol for an ohm is the greek capital-omega: Ω. The (somewhat roundabout) definition of 1Ω is the resistance between two points where 1 volt (1V) of applied potential energy will push 1 ampere (1A) of current.

As SI units go, larger or smaller values of ohms can be matched with a prefix like kilo-, mega-, or giga-, to make large values easier to read. It's very common to see resistors in the kilohm (kΩ) and megaohm (MΩ) range (much less common to see miliohm (mΩ) resistors). For example, a 4,700Ω resistor is equivalent to a 4.7kΩ resistor, and a 5,600,000Ω resistor can be written as 5,600kΩ or (more commonly as) 5.6MΩ.

Schematic symbol

All resistors have two terminals, one connection on each end of the resistor. When modeled on a schematic, a resistor will show up as one of these two symbols:

Resistor schematic symbols

Two common resistor schematic symbols. R1 is an American-style 1kΩ resistor, and R2 is an international-style 47kΩ resistor.

The terminals of the resistor are each of the lines extending from the squiggle (or rectangle). Those are what connect to the rest of the circuit.

The resistor circuit symbols are usually enhanced with both a resistance value and a name. The value, displayed in ohms, is obviously critical for both evaluating and actually constructing the circuit. The name of the resistor is usually an R preceding a number. Each resistor in a circuit should have a unique name/number. For example, here's a few resistors in action on a 555 timer circuit:

Answer: resistor is

Explanation:

A resistor controls the flow of the electrical current within a circuit. Resistors are made from materials like copper or carbon, which make it difficult for the electrical charges to flow through a circuit. The most common type of resistor is a carbon resistor, which is a general purpose resistor, best suited for lower-powered circuits.
