Answer:
3,6,9 is the answer it might be right but not sure
The balanced equation is C[tex]_3[/tex]H[tex]_8[/tex] + 5O[tex]_2[/tex] → 3CO[tex]_2[/tex] + 4H[tex]_2[/tex]O. An imbalanced chemical equation describes the products and reactants of a chemical process.
What is balanced equation?The balanced equation is indeed a chemical reaction equation in which the overall charge and the quantity of atoms for every element inside the reaction are identical for both the products and the reactants. In other terms, the mass plus charge on both side of the reaction are balanced.
An imbalanced chemical equation describes the products and reactants of a chemical process but does not include the quantities needed to meet mass conservation.
The carbon atom on lefts side is 3 while on right side it is 1
C[tex]_3[/tex]H[tex]_8[/tex] + O[tex]_2[/tex] → 3CO[tex]_2[/tex] + H[tex]_2[/tex]O
now balance oxygen
C[tex]_3[/tex]H[tex]_8[/tex] + 5O[tex]_2[/tex] → 3CO[tex]_2[/tex] + 4H[tex]_2[/tex]O

You are given two particles, each with a positive charge,
and a box that is 1 m by 1 m. How would you arrange the
particles to create the weakest electric force between
them? Explain.
Answer:
they are like charges so they magnitude repulsive & direction will be ones left &ones right. but it depends on the axis of rotation.
You are given two particles, each with a positive charge, and a box that is 1 m by 1 m. To arrange the particles to create the weakest electric force between them i put at opposite direction diagonally.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
According to Coulomb's law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Not all metals have the same current for a given electric potential
The statement 'Not all metals have the same current for a given electric potential' is TRUE. It is conductivity.
What is conductivity?All the metals are able to conduct electric currents, but some metals have a higher conductivity.
Metals are able to conduct electric currents due to the free movement of negatively charged particles i.e., electrons, across the conductor.
The band theory of metals states that metals can conduct electrons (e-) in an electric current by means of the help of the e- valence.
The density of free electrons in metals is around 10^28 m-3, which indicates the number of states at a particular energy level that negative e- can occupy.

A cart with mass 2m has a velocity v before it strikes another cart of mass 3m at rest. The two carts couple and move off together with a velocity of?
Answer:
2/5 v
Explanation:
Use conservation of momentum
originally mv = 2m v
after the crash mv is still the same (2mv)
but the mass is now 5m x where x is the new velocity
2mv = 5 mx
x = 2/5 v
The momentum of two objects in a collision is conserved. Hence, the total initial momentum is equal to the final momentum of the coupled mass. Here the final velocity will then be 2/5 v.
What is momentum ?Momentum of a moving object is the product of mass and velocity. It is a vector quantity with direction and magnitude. The total momentum of two colliding bodies is equal to the total final momentum after collision.
Let m1 and m2 be the masses and v1 and v2 be the final velocities. Vt be the velocity of the coupled mass.
Then, m1 v1 + m2 v2 = (m1 + m2) Vt
Given, mass of cart 1 = 2m
cart 2 = 3m
velocity of cart 1 = v
cart = 0 since it was at rest.
Then, 2m v + 0 = (2m + 3m) Vt
Vt = 2/5 v
Therefore, the final velocity of the couple of carts will be 2/5 v.

Water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell describes the movement of water when a cell shrinks and shrivels due to [ osmosis. Expert answered|emdjay23|Points 175268| Log in for more information.
Explanation:
Water went out of the cell because the concentration of water inside the cell was higher than the concentration outside the cell.
when there is a higher concentration of water inside the cell, water will begin to move out of the cell, eventually creating a hypertonic solution in which the cell shrivels and shrinks.
A bus is traveling at 25 m/s, and a cyclist is traveling at 5 m/s behind the bus, in the same direction. the frequency of a sound coming from the bus is observed by the cyclist to be 1000 hz. approximately what is the frequency of the sound as perceived by the bus driver
Answer:
Approximately [tex]1061\; {\rm Hz}[/tex] (rounded to the nearest whole number,) assuming that the speed of sound in the air is [tex]330\; {\rm m \cdot s^{-1}}[/tex].
Explanation:
Let [tex]v[/tex] denote the speed of this sound wave: [tex]v = 330\; {\rm m\cdot s^{-1}}[/tex] by assumption.
Let [tex]\Delta v[/tex] denote the speed at which the source (the bus) moves away from the observer (the cyclist.) In this question, [tex]\Delta v = 25\; {\rm m\cdot s^{-1}} - 5\; {\rm m\cdot s^{-1}} = 20\; {\rm m\cdot s^{-1}}[/tex].
Let [tex]d[/tex] denote the distance between the source (the bus) and the observer (the cyclist) when the first crest leaves the source. At a speed of [tex]v[/tex], it would take [tex]d / v[/tex] before the first crest arrive at the observer.
Let [tex]T[/tex] denote the period of this wave. If a crest of this wave leaves the source at [tex]t = 0[/tex], the very next one would leave at [tex]t = T[/tex]. Since the source is moving away from the observer at [tex]\Delta v[/tex], the distance between the two would have since increased from [tex]d[/tex] to [tex](d + \Delta v\times T)[/tex]. At a speed of [tex]v[/tex], this crest would now need [tex](d + \Delta v\times T) / v[/tex] to reach the observer.
In summary:
The first crest leaves the source at [tex]t = 0[/tex] and arrives at the observer at [tex]t = d / v[/tex].The second crest leaves the source at [tex]t = T[/tex] and arrives at the observer at [tex]t = T + (d + \Delta v\times T) / v[/tex].The time difference between the two crests is [tex]T[/tex] at the source. However, at the observer, this difference would have become:
[tex]\begin{aligned} &T + \frac{d + \Delta v\times T}{v} - \frac{d}{v} \\ =\; & T + \frac{\Delta v\times T}{v} \\ =\; & T\times \frac{v + \Delta v}{v}\end{aligned}[/tex].
Therefore, the ratio between the period at the source and at the observer would be:
[tex]\begin{aligned}\frac{T(\text{observer})}{T(\text{source})} &= \frac{\displaystyle T \times \frac{v + \Delta v}{v}}{T} \\ &= \frac{v + \Delta v}{v}\end{aligned}[/tex].
The frequency [tex]f[/tex] of a wave is equal to the reciprocal of its period [tex]T[/tex]. In other words, [tex]f = (1 / T)[/tex]. Therefore:
[tex]\begin{aligned}\frac{f(\text{observer})}{f(\text{source})} &= \frac{T(\text{source})}{T(\text{observer})} \\ &= \frac{v}{v + \Delta v}\end{aligned}[/tex].
Since [tex]f(\text{observer}) = 1000\; {\rm Hz}[/tex], [tex]\Delta v = 20\; {\rm m\cdot s^{-1}}[/tex], and [tex]v = 330\; {\rm m\cdot s^{-1}[/tex] by assumption:
[tex]\begin{aligned} & f(\text{source})\\ =\; & f(\text{observer}) \times \frac{v + \Delta v}{v} \\ =\; & 1000\; {\rm m\cdot s^{-1}} \times \frac{330\; {\rm m\cdot s^{-1}} + 30\; {\rm m\cdot s^{-1}}}{330\; {\rm m\cdot s^{-1}}} \\ \approx\; & 1061\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].
