The true statement about a series circuit is: the current flow through every part of the circuit is the same. Hence, option (B) is correct.
What are series and parallel circuit?Electrical networks and two-terminal components can be linked either serially or parallelly. The electrical network that results will have two terminals and be capable of operating in either a series or parallel topology.
It depends on your point of view whether a two-terminal "thing" is an electrical network (like resistors connected in series) or an electrical component (like a resistor). In this article, a two-terminal "thing" that participates in series/parallel networks will be referred to as a "component."
Each component connected in series travels the same "electrical path" and carries the same amount of current—equal to the network's current—through it.

The density of water is 1.00 g/cm3. The density of ethanol is 0.80 g/cm3. What is the volume of ethanol, in cm3 that has the same mass as 100 cm3 of water?
Explanation:
Given that,
The density of water is 1 g/cm³
The density of ethanol is 0.8 g/cm³
We need to find the volume of the ethanol that has the same mass as 100 cm³ of water.
Density=mass/volume
For water,
[tex]d=\dfrac{m}{V}\\\\m=dV\\\\m=1\ g/cm^3\times 100\ cm^3\\\\m=100\ g[/tex]
For ethanol,
[tex]d=\dfrac{m}{V}\\\\V=\dfrac{m}{d}\\\\V=\dfrac{100\ g}{0.8\ g/cm^3}\\\\V=125\ cm^3[/tex]
Hence, 125 cm³ of ethanol has the same mass as 100 cm³ of water.
Answer:
1.00 g/cm3

where
d is the distance
t is the time
From the question
d = 100 km
t = 5 hrs
We have
[tex]a = \frac{100}{5} \\ [/tex]

What makes an electric charge?
Answer:
Most electric charge is carried by the electrons and protons within an atom. Conversely, two protons repel each other, as do two electrons. Advertisement. Protons and electrons create electric fields, which exert a force called the Coulomb force, which radiates outward in all directions.
Which type of thermal energy transfer does a foil wrapping reduce the most? O A. Conduction O B. Translation O C. Radiation O D. Convection
The foil reduces radiation the most in terms of thermal energy transfer. Thermal energy transfer is the movement of heat from one place to another. The four types of thermal energy transfer are radiation, conduction, convection, and advection. The correct answer is option OC.
Foil wrapping reduces radiation as the most type of thermal energy transfer. Thermal energy transfer is the movement of energy from one place to another. There are four types of thermal energy transfer: conduction, convection, radiation, and advection. The foil wrapping reduces radiation the most. When there is a foil wrapped around food, the foil traps the heat inside the food, which reduces the radiation energy transfer. Radiation is the heat transfer that occurs in the form of electromagnetic waves. It requires no matter to move, which is why it can occur in the vacuum of space. Radiation transfer can be absorbed, transmitted, or reflected. Therefore, the correct answer is option OC.For more questions on radiation

what is the average velocity of a car that travels 30 kilometers due west in 0.50 hour
The average velocity of a car that travels 30 kilometers due west in 0.50 hour - 60 km/hour west.
Average velocity is the displacement of an object with the time change. To find the average speed of an object we divide the distance travelled by the time elapsed.
Velocity is a vector quantity and average velocity can be found by dividing displacement by time.Average velocity is defined as the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occursAverage velocity = ∆x/∆t
Then,
average velocity = 30/0.5
= 300/5
= 60
Thus, the correct answer would be - 60 km/hour west.

write the equation for calculating relative velocity in one dimensional.

Key Equations
Position Vector: `n r (t) = (t)^j+y
Total acceleration: `n a = `n aC
+ `n aT
Position Vector in frame S is the position Vector in frame S` plus the vector from the origin of S to the origin of S`: `n rPS = `n rPS`
+ `n rS`S
Relative velocity equation connecting two references frame: `n vPS = `n vPS`

How many hours would it take a plane to fly 1,500 miles if it was moving at a constant speed of 400 miles/hour.
It would take 3 hours and 45 minutes, for a plane to fly 1,500 miles if it was moving at a constant speed of 400 miles/hour.
Calculation
Round off 3.75 to the nearest one to give the hour value i.e., 3.The minutes are obtained by multiplying the fractional portion of the decimal value by 60, or 0.75 x 60 = 45.we have 3 hours and 45 minutes.What is speed?The distance traveled in a unit of time is called speed. It refers to a thing's rate of movement.This scalar quantity known as speed is the velocity vector's magnitude, It has no clear direction.A faster rate of movement is indicated by a higher speed. It is travelling more slowly if the speed is lower. It has zero speed if it isn't moving at all.The formula: can be used to determine the constant velocity of an object traveling straight forward.r = d / twhere,
r stands for rate or speed (sometimes denoted as v, for velocity)
d is the traveled distance.
t is the amount of time needed to finish the movement.
The average speed of an object over a period of time is given by this equation. We can see the object's average speed here, however at some moments over the time frame, it may have been moving faster or slower.As the time interval gets closer to zero, the maximum average speed is reached. The speed at that moment is what you see when you look at a speedometer in an automobile. While you may have briefly reached a speed of 60 mph, your average speed over the course of 10 minutes could have been much higher or much lower.M/s is the SI unit of speed (meters per second). Miles per hour or kilometers per hour are the most widely used units of speed in everyday life. A typical speed at sea is in knots, or nautical miles per hour.To learn more about speed, refer to https://brainly.com/question/24739297

1 a rectangular block of steel measures 4cm * 2cm* 1.5cm. its mass is 93 .6g
a) calculate the density of steel
b)steel is made up of almost entirely of atoms butt is denser than iron
suggest a reason for this
a) density = 93.6g/12cm³
= 7.8g/cm³
b) The reason is alloying
Explanation:
volume of the rectangular block = l× b × h
= (4 × 2 × 1.5)cm
= 12 cm³
density = mass/ volume
mass = 93.6g
volume = 12cm³
therefore,
density = 93.6g/12cm³
= 7.8g/cm³
b) °Steel is formed when alloying Iron with carbon.
°Alloying improves the physical properties of the metals and non-metals
