Answer:
increases
Explanation:
as we know, that submarines need to be really really strong to go down in the ocean. That means that the more they go down in the water (liquid) then, they will face more pressure. That as we said, that the more down they go, the more pressure will be on them, which means that the pressure will keep on increasing as you go down and down in the ocean.

If an object accelerates from rest, what will its velocity be after 2.1 s, if it has a constant acceleration of 9.8 m/s²?
If an object accelerates from rest, the velocity after 2.1 s, if it has a constant acceleration of 9.8 m/s² is 43.218 m/s².
To find the velocity, the given values are,
Time = 2.1 seconds
Acceleration = 9.8 m/s².
What is Acceleration?Acceleration can be defined as the rate of change of the velocity of an item with appreciation to time. Accelerations can be vector portions. The orientation of an item's acceleration is given by the orientation of the net pressure appearing on that object.
The acceleration will remain the same at 9.8 m/s². as under free fall conditions acceleration due to gravity remains constant.
Calculation:-
V = U + at
V = 0 + 9.8 × (2.1)²
= 9.8 × 4.41
= 43.218 m/s².
But, the acceleration will remain the same at 9.8 m/s neglecting air resistance.
Acceleration is the charge at which velocity modifications with time, in terms of each speed and route. A factor or an object moving in a straight line is accelerated if it quickens or slows down. movement on a circle is extended despite the fact that the rate is consistent because the course is continually changing.

Resistors are connected in parallel circuit
Voltage is constant as usual in circuitsCurrent is different#5
They differs
Because
For series connection
[tex]\\ \rm\rightarrowtail R_{net}=R_1+R_2\dots[/tex]
For parallel connection
[tex]\\ \rm\rightarrowtail \dfrac{1}{R_{net}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}\dots[/tex]
So resistance becomes low in parallel circuitSo, here for question no. 4 and 5, we are given a Diagram, which have 3 resistors connected in parallel each having a resistance of [tex]{\bf{2\Omega}}[/tex], [tex]{\bf{3\Omega}}[/tex] and [tex]{\bf{4\Omega}}[/tex]. And we are told to find a factor which will change for the given combination, and a factor which will not change, So here, as the resistors are connected in parallel, so the voltage will remain same for all the resistors, while the Current will be different for every resistor, And that's what the reason of why we always do connection in parallel for home purposes, because, we need voltage same in every resistor of the circuit. So, the factor which will change is [tex]{\boxed{\bf{Current}}}[/tex] and the factor which willn't change is [tex]{\boxed{\bf{Voltage}}}[/tex], and if the resistors were connected in Series combination, then current should be same for all resistors, while voltage will change.
Well, if the resistors are connected in the above way we have, and if we call our Resistors as [tex]{\bf{R_{1}}}[/tex], [tex]{\bf{R_{2}}}[/tex] and [tex]{\bf{R_{3}}}[/tex], then the equivalent resistance we will be having is :
[tex]{:\implies \quad \boxed{\bf{\dfrac{1}{R_{eq.}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}+\dfrac{1}{R_3}}}}[/tex]
Also, we can prove this fact just with the help of the reason provided in the above question, i.e that in Parallel combination, voltage remains same, but current changes, while in Series combination, current remains same but voltage changes, so we are just gonna prove the formula for both series combination and Parallel as well
So, let's prove the formula for series combination first, so consider n resistors connected in series, let Resistors as [tex]{\bf{R_{1},R_{2},R_{3}\cdots \cdots R_{n}}}[/tex], now as current will be same through all the resistors as connected in series, so if the current [tex]{\bf{I}}[/tex] from then, same current will flow through the whole circuit and each resistors, also let the voltages of every resistors being [tex]{\bf{V_{1},V_{2},V_{3}\cdots \cdots V_{n}}}[/tex], so now by Ohm's law, we can deduce that, the current from first circuit will be [tex]{\bf{V_{1}=IR_{1}}}[/tex]...and so on for all Resistors, and now if we add all resistors, so the equivalent Voltage will just be ;
[tex]{:\implies \quad \sf V_{eq.}=V_{1}+V_{2}+V_{3}+\cdots \cdots +V_{n}}[/tex]
[tex]{:\implies \quad \sf IR_{eq.}=IR_{1}+IR_{2}+IR_{3}+\cdots \cdots IR_{n}}[/tex]
[tex]{:\implies \quad \sf I(R_{eq.})=I(R_{1}+R_{2}+R_{3}+\cdots \cdots R_{n})}[/tex]
[tex]{:\implies \quad \boxed{\bf{R_{eq.}=R_{1}+R_{2}+R_{3}+\cdots \cdots R_{n}}}}[/tex]
Therefore, we proved for series.
Now, consider n resistors connected in parallel, with resistances, [tex]{\bf{R_{1},R_{2},R_{3}\cdots \cdots R_{n}}}[/tex], now as voltage will be same through all the resistors as connected in parallel,while current will change, so let total voltage be [tex]{\bf{V}}[/tex], and current for each resistor as [tex]{\bf{I_{1},I_{2},I_{3}\cdots \cdots I_{n}}}[/tex],so by using the same concept as above we can write by using ohm's law :
[tex]{:\implies \quad \sf I_{eq.}=I_{1}+I_{2}+I_{3}+\cdots \cdots +I_{n}}[/tex]
Rewrite using ohm's law :
[tex]{:\implies \quad \sf \dfrac{V}{R_{eq.}}=\dfrac{V}{R_1}+\dfrac{V}{R_2}+\dfrac{V}{R_3}+\cdots \cdots +\dfrac{V}{R_n}}[/tex]
[tex]{:\implies \quad \sf V\dfrac{1}{R_{eq.}}=V\bigg(\dfrac{1}{R_1}+\dfrac{1}{R_2}+\dfrac{1}{R_3}+\cdots \cdots +\dfrac{1}{R_n}\bigg)}[/tex]
[tex]{:\implies \quad \boxed{\bf{\dfrac{1}{R_{eq.}}=\dfrac{1}{R_{1}}+\dfrac{1}{R_{2}}+\dfrac{1}{R_{3}}+\cdots \cdots +\dfrac{1}{R_{n}}}}}[/tex]
Hence, we proved for Parallel combination too
Also, refer to the attachment for a better understanding, and just a point that Voltmeter is always connected in parallel while ammeter in series, and all the things above are taken in SI units
How can the intensity of a sound be changed without changing the pitch
Answer:
Sound waves are greatly affected by the medium in which they travel, not just in terms of speed, but also in terms of loudness and tonal quality. Just think of the variation in loudness and sound quality of different acoustic guitars which may use the same strings, but the sound is greatly affected by the different media in which it travels, including the wood, sound cavities, even the varnish on the instrument.

how does the mass of an object affect its acceleration
Answer:
Explanation:
For an object falling under the influence of gravity, the mass does not affect the acceleration -- that is a constant called "g". As the mass gets larger, it takes a greater force (supplied by the greater weight) to be able to support the same acceleration. g=F/m. The weight (the force) is proportional to mass, so the fraction is the constant g.
Answer:
As the mass of an object is increased, the acceleration of the object is decreased.
My explanation:
I like to think of it as if you have a wooden car going straight forward it will go a certain speed, if you add a 1 pound weight to that very same car it will go slower than the car without the weight.

Myra solved an inequality to determine the number of rolls of wrapping paper the school band must sell to meet their fundraising goal. The number line below shows the solution to the inequality. A number line going from 184 to 190. An open circle is at 188. Everything to the right of the circle is shaded. Which phrase best describes the number of rolls the band must sell?
The solution of the inequality means that the band must sell more than 188 rolls of wrapping paper.
How to interpret a solution of an inequality?
We are told that the solution to the inequality is represented with a number line that goes from 188 to 190, such that we have an open circle at 188 and all the region to the right is shaded.
The open circle means that the point itself is not a solution, and because the region at the right is shaded, the solutions are larger than 188, then the solution of this inequality will be:
188 < x.
If x represents the number of rolls of wrapping paper that the band must sell, this means that the band must sell more than 188 rolls of wrapping paper.

If you can make it from one end of a football field to the other (100 meters) with an acceleration of 2.2m/s, what would be your top speed if you started from rest?
Answer:
v = 20.57 m/s
Explanation:
Given that,
Acceleration, a = 2.2 m/s²
Initial speed of the person, u = 0 (at rest)
Distance, s = 100 m
We need to find the top speed. It can be calculated using third equation of motion.
[tex]v^2-u^2=2as[/tex]
v is final speed
[tex]v=\sqrt{2as} \\\\v=\sqrt{2\times 2.2\times 100} \\\\v=20.57\ m/s[/tex]
So, the top speed of the person is 20.57 m/s.

El neumático de un automóvil se infla a una presión manométrica de 207 KPa la cual equivale a(30 lb/in²) en un momento en que la presión de los alrededores es de 1 atmosfera (1 atm = 101,3 KPa) y la temperatura es de 25 °C. Después de manejarlo, la temperatura del aire del neumático aumenta a 40 °C. Supongamos que el volumen del gas cambia sólo ligeramente. ¿Cuál es la nueva presión manométrica en el neumático?
Answer:
La nueva presión manométrica en el neumático es 117,48 kilopascales.
Explanation:
Supongamos que el gas contenido en el neumático del automóvil se comporta como un gas ideal, cuya ecuación de estado es:
[tex]P\cdot V=n\cdot R_{u}\cdot T[/tex] (Eq. 1)
Donde:
[tex]P[/tex] - Presión absoluta del aire, medido en kilopascales.
[tex]V[/tex] - Volumen del aire, medido en metros cúbicos.
[tex]n[/tex] - Cantidad molar del aire, medida en moles.
[tex]T[/tex] - Temperatura del aire, medida en Kelvin.
[tex]R_{u}[/tex] - Constante universal de los gases ideales, medida en kilopascal-metros cúbicos por mol-Kelvin.
Si sabemos que el neumático experimenta un proceso isocórico e isomolar de calentamiento y presurización, entonces podemos reducir la ecuación de estado a la siguiente relación:
[tex]\frac{P_{A}}{T_{A}} = \frac{P_{B}}{T_{B}}[/tex] (Eq. 2)
Donde:
[tex]P_{A}[/tex], [tex]P_{B}[/tex] - Presiones absolutas inicial y final del aire, medidas en kilopascales.
[tex]T_{A}[/tex], [tex]T_{B}[/tex] - Temperaturas inicial y final del aire, medidas en Kelvin.
Despejamos la presión absoluta final del aire:
[tex]P_{B} = \frac{T_{B}}{T_{A}}\cdot P_{A}[/tex]
La presión absoluta es la suma de la presión atmosférica y la presión manométrica, todas medidas en kilopascales. La presión absoluta inicial del aire es:
[tex]P_{A} =101,3\,kPa + 207\,kPa[/tex]
[tex]P_{A} = 208,3\,kPa[/tex]
Si [tex]T_{A} = 298,15\,K[/tex], [tex]T_{B} =313,15\,K[/tex] y [tex]P_{A} = 208,3\,kPa[/tex], la presión absoluta final del aire es:
[tex]P_{B} = \left(\frac{313,15\,K}{298,15\,K} \right)\cdot (208,3\,kPa)[/tex]
[tex]P_{B} = 218,780\,kPa[/tex]
Ahora, la presión manométrica final en el neumático es:
[tex]P_{man, B} = 218,780\,kPa-101,3\,kPa[/tex]
[tex]P_{man, B} = 117,48\,kPa[/tex]
La nueva presión manométrica en el neumático es 117,48 kilopascales.
