The graph shows the layers of Earth's atmosphere. Which statement best describes the relationship between temperature and altitude in the atmosphere?
A. The relationship between temperature and altitude is variable and unpredictable.
B. Overall, the temperature of the atmosphere increases with altitude.
C. The relationship between temperature and altitude is different in each zone of the atmosphere.
D. Temperature decreases with altitude until the stratosphere is reached, and then it increases from there.
Answer:
The best statement which describe this is actually:
D. Temperature decreases with altitude until the stratosphere is reached, and then it increases from there.
Explanation:
From the graph shown, it could be seen that, temperature decrease with height. The higher the height, the lower the temperature. For example, from the graph, when the height was around 50 km, the temperature was within the range of -10⁰C to 0⁰C. On the other hand, when the height increases around 78 km, the temperature decreases to the range of to -70 ⁰C to -80⁰C

First, evaluate these three models. One represents fission, one fusion, and one radioactive decay. Write three sentences about each one according to the following framework:
---State what reaction the model represents, including what it demonstrates about mass and/or energy.
---State whether you think the model accurately represents the reaction. Explain why or why not.
---Suggest one way to improve the model.
Model A: Two sponge balls representing two atoms are soaked in water. You hold one ball, and your friend holds the other. Then you press the two balls together. As you press them together, water leaks out. What type of reaction does this model represent?
Model B: You draw a tree diagram showing a large atom splitting into two parts and neutrons being released. Your diagram also shows the released neutrons hitting other large atoms, which then each split in two and release more neutrons, which hit more large atoms, and so on. What type of reaction does this model represent?
Model C: You have 100 candies with the letter "M" on one side. You pour the candies into a pan. You count and remove all the candies with the "M" facing upward. Then you shake the pan and again count and remove all the candies with "M" facing upward. You shake, count, and remove candies four more times. What type of reaction does this model represent?
When energy is transferred from system to surrounding then the corresponding reaction known as exothermic reaction in Modle A when we press the ball(atom) the water(energy) is transferred into surrounding hence it is an exothermic reaction.
When a single atom disintegrate to give two or more atom with radioactive substance then the corresponding reaction know as Nuclear Fission reaction. hence Modle B represents Nuclear fission reaction.
The Model C represents Radioactive decay, So in the given example or model the water is playing role of radiation through which we are removing the candies having M on upside.

Explanation:
for every 1000 joules or useful energy output, the heater wastes 100 joules, find the input energy of the heater.
Answer:
the Input Energy is 1,100 J
Explanation:
Given;
useful energy, = 1000 J
energy wasted, = 100 J
The total or input energy is given as;
Input Energy = useful energy + energy wasted
Input Energy = 1000 J + 100 J
Input Energy = 1,100 J
Therefore, the Input Energy is 1,100 J

A roller coaster goes down a slope with a starting speed of 5 m/s then 6
seconds later at the bottom of the slope the roller coaster is moving at a
speed of 27 m/s. What is the acceleration of the roller coaster? **Round to
1 decimal place**
Answer:
Acceleration = 3.67 m/s²
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
Given the following data;
Initial velocity, u = 5 m/s
Final velocity, v = 27
Time, t = 6
To find the acceleration;
Acceleration = (v - u)/t
Acceleration = (27 - 5)/6
Acceleration = 22/6
Acceleration = 3.67 m/s²

A 37 kg child jumps in the air. At the maximum height of the jump, the GPE is 500J. If the mass of the boy is tripled, how much Potential Energy does the child have at the top of his jump? If the same boy's mass is doubled, but his height is quadupled, how much Potential Energy does the child have at it's maximum and in what position in the jump will he be?
Answer:
*Answers are in their respective order with the questions.
[tex]1500\:\mathrm{J},\\4500\:\mathrm{J},\\5.52\:\mathrm{m}[/tex]
Explanation:
The [gravitational] potential energy of an object is given by [tex]PE=mgh[/tex], where [tex]m[/tex] is the mass of the child, [tex]g[/tex] is acceleration due to gravity, and [tex]h[/tex] is the height of the object (relative to the ground).
"If the mass of the boy is tripled, how much potential energy does the child have at the top of his jump?"
Without actually plugging and chugging, notice the formula in which gravitational potential energy is given. Potential energy is directly proportional to mass. Therefore, if the mass of the boy is tripled, his potential energy will also be tripled, yielding an answer of [tex]500\cdot 3=\boxed{1500\:\mathrm{J}}[/tex]
"If the same boy's mass is doubled, but his height is quadrupled, how much potential energy does the child have at its maximum and in what position in the jump will he be?"
In similar fashion to the first question, we can note that the potential energy of an object is directly proportional to its mass and height. Therefore, if the boy's mass is doubled and his height is quadrupled, his potential energy will be [tex]2\cdot 4=8[/tex] times as large at maximum height. Thus, he will have [tex]500\cdot 8 =4,000\:\mathrm{J}[/tex] of potential energy at the maximum height. I'm assuming that "in what position in the jump will he be?" is asking for the height at the maximum height of the jump.
The original height can be solved using:
[tex]PE=mgh,\\500=37\cdot 9.8\cdot h,\\h=\frac{500}{37\cdot 9.8}=1.37892995036\:\mathrm{m}[/tex]
Quadrupled implies being multiplied by four. Therefore, we have:
[tex]h'=1.37892995036\cdot 4=5.51571980143\approx \boxed{5.52\:\mathrm{m}}[/tex]

a snail is at rest. it accelerates at a rate of 0.0075m/s^2. calculate the time it takes to reach a speed of 0.0135m/s
Answer:
1.8 secondsExplanation:
Initial velocity (u) = 0 m/s[Since, it is at rest. ]
Acceleration (a) = 0.0075 m/s²Final velocity (v) = 0.0135 m/s²We are asked to calculate time taken to reach a speed of 0.0135m/s.
By using the first equation of motion,
→ v = u + atv denotes final velocityu denotes initial velocitya denotes accelerationt denotes time takenSubstituting values,
→ 0.0135 = 0 + 0.0075t
→ 0.0135 = 0.0075t
→ 0.0135 ÷ 0.0075 = t
→ 1350000 ÷ 750000 = t
→ 135 ÷ 75 = t
→ 1.8 = t
→ Time taken = 1.8 secondsTherefore, it takes 1.8 seconds to reach a speed of 0.0135m/s.
Wants to slide his 430g water bottle precisely 12m to land inside a Bull's Eye! If the coefficient of kinetic friction between the bottle and the surface is 0.62, calculate the initial speed he must release the bottle?
Answer:
Ff = u M g frictional force where u = .62
1/2 M v^2 kinetic energy of water bottle at release
Ff * d = 1/2 M v^2 = u M g d work to stop equals initial kinetic energy
v^2 = 2 u g d = 2 * .62 * 9.8 * 12 = 146 m^2 / s^2

A particle of mass m and charge q is released from rest in a uniform electric field Find the momentum attained by the particle after moving distance xis
Answer:
Momentum = 2qEx/v
Explanation:
From the work - energy theorem, we know that;
Kinetic energy = work done
Now, formula for both are;
Kinetic energy = ½mv²
Work done = qEx
Where;
m is mass
v is velocity
q is charge
E is Electric field
x is distance covered.
Thus;
½mv² = qEx - - - - (eq 1)
Now, momentum formula is;
p = mv
Let's rewrite the left hand side of equation 1 to reflect p = mv. Thus;
½v(mv) = qEx
½vp = qEx
p = 2qEx/v

Justin mixed two cups of lemon juice and two cups of sugar with a gallon of water in a pitcher. What happened to the lemon juice, sugar, and water?
Answer:
The correct answer is - Lemon juice hydrolyzes sugar and dissolves it faster and creates a solution.
Explanation:
When mixing lemon juice and sugar in water are mixed together, the lemon juice dissolves the sugar faster as it has citric acid that hydrolyzes sucrose molecules of sugar in glucose and fructose.
This mixing of all three lemon juice, water, and sugar form a solution. Here in this solution, water is solvent, and sugar and lemon juice are solutes. The quantity of all three determined the nature of the solution if it will be acidic or more diluted.
Cuánta cantidad de calor de un Añadir a un reciente de agua de 1000 G de masa Una temperatura de 40 grados centígrados para que toda esta agua se vuelva a vapor
Answer:
Q = 251040 J o 251 KJ
Explanation:
Cantidad total de agua = 1000 gramos
Temperatura inicial (T1) = 40 grados Celsius
Temperatura final (T2) = 100 grados Celsius (temperatura de ebullición del agua)
Calor específico del agua (C) = 4.184 J / g
Tal como lo conocemos
Q = m * C * (T2-T1)
Sustituyendo los valores dados, obtenemos -
Q = 1000g * 4,184 J / g / grado Celsius * (100-40) grados Celsius
Q = 1000 * 4,184 * 60 J
Q = 251040 J o 251 KJ
