Answer:
The correct answer is: in the magma chamber.
Explanation:
The volcanoes are creating igneous rocks, and they can be intrusive and extrusive. The intrusive ones are forming deep into the ground, while the extrusive are forming on the surface. Where the rocks are formed makes a big difference in their crystals size. The rocks that form by magma that has cooled the deepest into the ground would have the largest crystals, thus the coarsest grains. The reason for this is that the magma that has been cooling the deepest into the ground will be exposed to higher temperatures and pressures, which will lead to a very slow cooling off. Because the cooling off will be at such a slow rate, the crystals will have enough time to became much larger. The deepest part of a volcano is its magma chamber, thus it will be the place that will produce the coarsest grained igneous rocks.
what type of meter is connected in parallel in a circuit and why
Potential difference is measured using a device called a voltmeter . Just like ammeters, some types have a pointer on a dial, but most have a digital display. However, unlike an ammeter, you must connect the voltmeter in parallel to measure the potential difference across a component in a circuit.

What crop is least likely to do well when the temperatures are very hot?
a. sweet corn
b. spinach
c. tomatoes
d. okra
PLEASE HURRY
a. Sweet corn and possibly d. okra.
Spinach is the crop least likely to do well in very hot temperatures due to its preference for cooler temperatures and increased likelihood of bolt when exposed to high heat.
Explanation:The crop that is least likely to do well when the temperatures are very hot is spinach.
Spinach is a cool-season vegetable that prefers temperatures between 35 and 75 degrees Fahrenheit. When exposed to high temperatures, spinach is more prone to bolting, which means it quickly produces flowers and seeds instead of growing leaves. This affects the flavor and texture of the spinach, making it less desirable.
Sweet corn, tomatoes, and okra, on the other hand, are warm-season crops that are better adapted to hot temperatures and can tolerate higher heat without significant negative effects.

Boltzmann’s constant is 1.38066 × 10−23 J/K, and the universal gas constant is 8.31451 J/K · mol.
If 2.4 mol of a gas is confined to a 4.3 L vessel at a pressure of 11 atm, what is the average kinetic energy of a gas molecule? Answer in units of J.
Answer:
[tex]4.95\cdot 10^{-21} J[/tex]
Explanation:
First of all, let's convert everything into SI units:
n = 2.4 mol (number of gas moles)
[tex]p=11 atm = 1.11\cdot 10^6 Pa[/tex] (gas pressure)
[tex]V=4.3 L=4.3\cdot 10^{-3} m^3[/tex] (gas volume)
R = 8.31451 J/K · mol (gas constant)
The ideal gas equation states that
[tex]pV=nRT[/tex]
Solving for T, we find the gas temperature
[tex]T=\frac{pV}{nR}=\frac{(1.11\cdot 10^6)(4.3\cdot 10^{-3})}{(2.4)(8.31451)}=239.2 K[/tex]
And now we can find the average kinetic energy of the gas:
[tex]E_K = \frac{3}{2}kT[/tex]
where
k = 1.38066 × 10−23 J/K is the Boltzmann's constant
Substituting,
[tex]E_K = \frac{3}{2}(1.38066\cdot 10^{-23} J/K)(239.2 K)=4.95\cdot 10^{-21} J[/tex]
The average kinetic energy of the gas molecule is 4.97 × 10⁻²¹ J
Calculating the average kinetic energy of a gas moleculeFrom the question, we are to calculate the average kinetic energy of the gas molecule.
The average kinetic energy of a gas molecule can be calculated from the formula,
[tex]KE_{avg}=\frac{3}{2}k_{b}T[/tex]
Where [tex]k_{b}[/tex] is the Boltzmann's constant
and T is the temperature
Now, we will determine the temperature of the gas
From the given information
R = 8.31451 J/K.mol
n = 2.4 moles
V = 4.3 L
P = 11 atm = 1114.58 KPa
From the ideal gas equation
PV=nRT
Then, we can write that
[tex]T = \frac{PV}{nR}[/tex]
Putting the parameters into the equation, we get
[tex]T = \frac{1114.58 \times 4.3}{2.4 \times 8.31451}[/tex]
T = 240.1772
T ≅ 240.2 K
Now, for the average kinetic energy of the gas molecule
[tex]KE_{avg}=\frac{3}{2}k_{b}T[/tex]
From the given information
[tex]k_{b} = 1.38066 \times 10^{-23}[/tex]
∴ [tex]KE_{avg}=\frac{3}{2} \times 1.38066 \times 10^{-23} \times 240.2[/tex]
[tex]KE_{avg}= 4.97 \times 10^{-21} \ J[/tex]
Hence, the average kinetic energy of the gas molecule is 4.97 × 10⁻²¹ J

B is a speed.
A is an acceleration.
C and D are velocities.
The example of speed, with the unit as m/s (meter per second) in the following options is, option B. The option B has speed of 2 meter per second.
What is speed?Speed of an body is the distance traveled by it with respect to time. Speed of a object is the ratio of total distance traveled by the object to the time taken by it. It can be given as,
[tex]s=\dfrac{x}{t}[/tex]
Here, (x) is the distance traveled by a body and (t) is the time taken by it.
As the distance is measured in the meters and time is measured in the second. Thus the speed of an object is measured in meter per second (m/s).
When the distance travelled by an object with respect to time is represented with its direction, then it is called the velocity of the object in that direction.
The rate of change of velocity is called the acceleration. It is represented in the meter per squared second (m/s²).

In a circuit what do lightbulbs and a toaster represent
Answer:
RESISTANCE
Explanation:
Answer:
Resistance
Explanation:
In a circuit, voltage source (cell or battery), key (for closing and opening circuit), resistance and a conducting wire are main components. Ohm's law states that current flowing in the circuit is proportional to the potential difference across the two ends.
V = I R
Where R is the resistance. Current also depends on the resistance. Greater resistance means lesser current would flow.
A light bulb and toaster represent resistance. These devices are based on Joule's Heating. When current passes through a resistance, it heats up and energy is lost as heat in case of toaster and as heat and light in case of light bulbs.

A washing machine is plugged into a wall outlet that has voltage of 240 volts. The total resistance present in the machine's wiring is 12 ohms. What current runs through this current
The resistance between the two sides of an outlet should be infinite. The two sides of the outlet are not connected to one another in any fashion as they are two sides of a circuit. The diagram below shows how this works. In an AC circuit, as shown below, the black wire provides AC power, the white is common, and the green is ground. Back in your breaker box, the common wires all go to one buss bar that is to earth ground and the ground wires go to earth ground as well by a separate path making sure that the residual voltage on the common doesn't cross over to the ground wire of another circuit. In the right hand diagram, they show how to connect wires for a series (daisy chain) to another outlet.
So my question is why are you trying to measure resistance here? Normally we would measure voltage. Are you trying to diagnose a circuit problem? In a 110vac system you should have 110vac from black to white and black to green and none from white to green (ideally if nothing is plugged into any outlets). With the breaker off, you should be able to measure the resistance between the two posts on the black side, and that should be 0ohms as they are the same point.
Current = (voltage) / (resistance)
Current = (240 V) / (12 ohms)
Current = 20 Amperes
Ashlee pours some quantity of orange juice in a glass. She accidentally breaks the glass and juice spills all over the floor. Which characteristic of the juice will change?
A. mass
B. State
C. Shape
D. Volume
Only the shape of the juice will change (C), because liquids take the shape of any container you pour them into.
Pouring the juice from the bottle into the glass doesn't change its mass, stat, or volume. So why should pouring it from the glass onto the floor change any of those things ?
When Ashlee spills the orange juice on the floor, the characteristic that changes is the volume of the juice.
The characteristic of the juice that will change when it spills all over the floor is its volume. When the glass breaks, causing the juice to spill, the volume of the juice will no longer be contained within the glass.

A glass jug can be used to play different pitched sounds by blowing air over the opening of the jug and vibrating the air molecules inside the jug. The sound fluctuates with the amount of liquid in the jug, similar to the length of a pipe organ. A musician wishes to play a higher-pitched sound with their jug. What should they do?
Force more air over the opening of the jub
Remove more liquid
Add more liquid
To increase the pitch of the jug sound, remove more liquid; doing so decreases the air column inside the jug which makes the vibration faster, thereby increasing the pitch.
Explanation:The pitch of the sound produced by a jug when blown across the top is determined by the column of air that can vibrate inside the jug. The longer the air column, the lower the pitch of the sound, analogous to how longer pipes in a pipe organ produce lower notes. Therefore, to play a higher-pitched sound with a jug, the musician should remove more liquid from the jug. By doing so, he decreases the air column which makes the vibration faster, thus producing a higher-pitched sound. It is important to note that forcing more air over the opening of the jug does not change the pitch of the sound but increases the volume while adding more liquid produces a lower-pitched sound.

A brick lands 10.1 m from the base of a building. If it was given an initial velocity of 8.6 m/s [61º above the horizontal], how tall is the building?
First, we have to establish the reference system. Let's assume that the building is on the negative y-axis and that the brick was thrown at the origin (see figure attached).
According to this, the initial velocity [tex]V_{o}[/tex] has two components, because the brick was thrown at an angle [tex]\alpha=61\º[/tex]:
[tex]V_{ox}=V_{o}cos\alpha[/tex] (1)
[tex]V_{ox}=8.6\frac{m}{s}cos(61\º)=4.169\frac{m}{s}[/tex] (2)
[tex]V_{oy}=V_{o}sin\alpha[/tex] (3)
[tex]V_{oy}=8.6\frac{m}{s}sin(61\º)=7.521\frac{m}{s}[/tex] (4)
As this is a projectile motion, we have two principal equations related:
In the x-axis:[tex]X=V_{ox}.t[/tex] (5)
Where:
[tex]X=10.1m[/tex] is the distance where the brick landed
[tex]t[/tex] is the time in seconds
If we already know [tex]X [/tex] and [tex]V_{ox}[/tex], we have to find the time (we will need it for the following equation):
[tex]t= \frac{X}{ V_{ox}}[/tex] (6)
[tex]t=2.42s[/tex] (7)
In the y-axis:[tex]-y=V_{oy}.t+\frac{1}{2}g.t^{2}[/tex] (8)
Where:
[tex]y[/tex] is the height of the building (in this case it has a negative sign because of the reference system we chose)
[tex]g=-9.8\frac{m}{s^{2}}[/tex] is the acceleration due gravity
Substituting the known values, including the time we found on equation (7) in equation (8), we will find the height of the building:
[tex]-y=(7.521\frac{m}{s})(2.42s)+\frac{1}{2}(-9.8\frac{m}{s^{2}}).(2.42s)^{2}[/tex] (9)
[tex]-y=-10.52m[/tex] (10)
Multiplying by -1 each side of the equation:
[tex]y=10.52m[/tex] >>>>This is the height of the building

Pls mark Brainiest, am trying to become Virtuoso
Help with this physics question pls!
The answer would be:
X convex mirror
Y concave mirror
Here's more about it:
Convex mirrors are used in side mirrors in cars because it has a wider field of view than others. This is because convex mirrors bend the light it reflects. The more it bends the light. The further the object is from the mirror, the image that will be produced will be smaller. That's why the side mirrors usually say that objects are closer than they appear.
A concave lens on the other hand, reflect light inwards, away from the light source. That's why they are used in telescopes, ,because they are used to collect light. The images that concave mirrors produces are enlarged.

how is sound detected by the brain
begin with vibrations of the eardrum. Sound waves cause the eardrum to vibrate. Cells in the cochlea detect the vibrations and send a message to the brain.
Answer:
Sound must have a means by which it can be transported, for example air. That is why there is no sound in space.
The way our brain perceives sound is through the ears. The tympanum that the human being has is connected to three bones and when the air vibrates, the tympanum also vibrates, causing these vibrations to pass through those bones towards the inner part of the ears and from there to our brain.
That is the way the brain perceives sound.
the chemical formula for cesium oxide is cs2o. what is the charge of cesium
Charge +1
Explanation;Cs2O is a neutral compound, so the sum of the charges must total up to zero. Oxygen always has a charge of -2, so this means that Cs2 must have a sign of +2. Since +2 is the charge for 2 Cs atoms, this means that each Cs atom has a charge of +1.That is; (1 × -2) + (2 × x) = 0 , where x is the charge of Cs
= -2 + 2x = 0
= 2x = +2
x = +1
The charge of cesium in the compound with a formula of Cs₂O is +1
How do i determine the charge of cesium?To obtain the charge of cesium, Cs in the compound with a formula of Cs₂O, we shall determine the oxidation number of cesium, Cs in the compound. This is illustrated below:
Compound = Cs₂OOxidation number of O = -2Oxidation number of Cs =?Cs₂O = 0 (Ground state)
2Cs + O = 0
2Cs - 2 = 0
Collect like terms
2Cs = 2
Divide both sides by 2
Cs = 2/ 2
Cs = +1
Thus, we can conclude from the above calculation that the charge of cesium, Cs is +1

Which statement is true about the law of conservation of energy for an object released from a certain height above the ground
The question is really specific enough, but I will take a guess. If nothing else changes (like the mass or the gravitational constant) then the Potential Energy will increase with an increase in height. Ep will decrease with a decrease in height.
If you are talking about Ke, then the height does not matter unless the object is moving up. Then it slows down. When that happens the Ke decreases because the formula for Ke = 1/2 m v^2. If v becomes less then Ke becomes less.
I suppose you could say if the object is going down and the distance is decreasing then the speed will increase. It's an inverse relationship.
I think you are best talking about Pe.

4 m/s²
Explanation;When both forces point due east then;
the resultant force will be; 10 + 30 = 40 N due east
But; From second Newton's law of motion;
F = ma
Thus;
a = F/m ; F= 40 N and mass = 10 kg
= 40/ 10
= 4 m/s² to wards east
2. Answer;1 m/s²
Explanation;when 10 N force points due east and 30 N force points due west then;
the resultant force will be; 30 N - 10 N = 10 N due west
But; From second Newton's law of motion;
F = ma
Thus;
a = F/m
= 10 /10
= 1 m/s² , towards the west direction
Explanation:
Given that,
First force = 10 N
Second force = 30 N
Mass of box = 10 kg
(1). When both forces point due east
Then the net force will be
[tex]F_{net}=F_{1}+F_{2}[/tex]
[tex]F_{net}=10+30[/tex]
[tex]F=40 N[/tex]
We need to calculate the acceleration
Using newton's second law
[tex]F= ma[/tex]
put the value into the formula
[tex]40=10\times a[/tex]
[tex]a=\dfrac{40}{10}[/tex]
[tex]a=4\ m/s^2[/tex]
The box accelerate towards east.
(2). When 10 N force points due east and 30 N force points due west.
Then the net force will be
[tex]F_{net}=F_{2}-f_{1}[/tex]
[tex]F_{net}=30-10=20\ N[/tex]
We need to calculate the acceleration
Using newton's second law
[tex]F= ma[/tex]
[tex]20=10\times a[/tex]
[tex]a=\dfrac{20}{10}[/tex]
[tex]a=2\ m/s^2[/tex]
The box accelerate towards west.
Hence, This is the required solution.

Why?Since we know the angle and the horizontal component (x-axis component) of the initial velocity, we can calculate the actual velocity (initial velocity) using the following equation:
[tex]Vo_{x}=Vo*Cos\alpha[/tex]
Where:
[tex]Vo_{x}=40\frac{m}{s}\\Vo= Initial velocity\\\alpha = angle= 30 (degrees)[/tex]
So, from the equation we can calculate Vo,
[tex]Vo_{x}=Vo*Cos\alpha\\\\\frac{Vo_{x}}{Cos\alpha}=Vo[/tex]
Then, by substituting we have:
[tex]Vo=\frac{40\frac{m}{s} }{Cos30}=\frac{40\frac{m}{s}}{0.866}=46.19\frac{m}{s}[/tex]
Have a nice day!
