In a chemical reaction, carbon combines with oxygen to form carbon dioxide gas.
What is a chemical reaction?A chemical reaction can be defined as a process that causes the chemical transformation of one chemical substance to another. The chemical reactions accompany chemical changes that involve the rearrangement of electrons in the forming and breaking of bonds between atoms, with no change to the nuclei.
The substances which are primarily involved in a reaction are known as reactants or reagents. Chemical reactions are commonly characterized by a chemical change, and yield products, which exhibit properties different from the reactants.
Chemical reactions take place at a characteristic rate of reaction at a given temperature, pressure, and chemical concentration. The rates increase with the increasing temperature of the reaction when more thermal energy is available to achieve the activation energy for breaking bonds between atoms.
The combustion reaction takes place when carbon combines with oxygen to produce carbon dioxide gas.

A disk of a radius 50 cm rotates at a constant rate of 100 rpm. What distance in meters will a point on the outside rim travel during 30 seconds of rotation?
Answer:
A point on the outside rim will travel 157.2 meters during 30 seconds of rotation.
Explanation:
We can find the distance with the following equation since the acceleration is cero (the disk rotates at a constant rate):
[tex] d = v*t [/tex]
Where:
v: is the tangential speed of the disk
t: is the time = 30 s
The tangential speed can be found as follows:
[tex] v = \omega*r [/tex]
Where:
ω: is the angular speed = 100 rpm
r: is the radius = 50 cm = 0.50 m
[tex] v = \omega*r = 100 \frac{rev}{min}*\frac{2\pi rad}{1 rev}*\frac{1 min}{60 s}*0.50 m = 5.24 m/s [/tex]
Now, the distance traveled by the disk is:
[tex] d = v*t = 5.24 m/s*30 s = 157.2 m [/tex]
Therefore, a point on the outside rim will travel 157.2 meters during 30 seconds of rotation.

Consider a simple pendulum that consists of a massless 2.00-meter length of rope attached to a 5.00-kg mass at one end. What happens to the frequency of oscillation of the pendulum if we double the length of the rope
Answer:
If we double the length we will have:
[tex]f'=\frac{f}{\sqrt{2}}[/tex]
Explanation:
The equation of the angular frequency of a pendulum is given by:
[tex]\omega=\sqrt{\frac{g}{L}}[/tex]
Where:
g is the gravityL is the length of the pendulumBy definition the period is:
[tex]T=\frac{2\pi}{\omega}[/tex]
And frequency is 1 over the frequency T:
[tex]f=\frac{1}{T}[/tex]
[tex]f=\frac{1}{2\pi}\sqrt{\frac{g}{L}}[/tex]
Now, if we double the length we will have:
[tex]f'=\frac{1}{2\pi}\sqrt{\frac{g}{2L}}[/tex]
[tex]f'=\frac{1}{2\pi\sqrt{2}}\sqrt{\frac{g}{L}}[/tex]
[tex]f'=\frac{f}{\sqrt{2}}[/tex]
Therefore, the new frequency is the old frequency over √2.

As you look out of your dorm window, a flower pot suddenly falls past. The pot is visible for a time t, and the vertical length of your window is Lw. Take down to be the positive direction, so that downward velocities are positive and the acceleration due to gravity is the positive quantity g. Assume that the flower pot was dropped by someone on the floor above you (rather than thrown downward). If the bottom of your window is a height hb above the ground, what is the velocity vground of the pot as it hits the ground? You may introduce the new variable vb, the speed at the bottom of the window, defined by
vb = Lwt + gt2.
Answer:
[tex]\mathbf{v_{ground} = \sqrt{{v^2+2ghb}}}[/tex]
Explanation:
From the information given:
The avg. velocity post the window is;
[tex]v_{avg} = \dfrac{L_w}{t}[/tex]
[tex]v_b[/tex] = velocity located at the top of the window
[tex]v_b[/tex] = velocity situated at the bottom of the window
Using the equation of kinematics:
[tex]v_b = v_t + gt[/tex]
Hence,
[tex]v_t = v_b - gt[/tex]
To determine the average velocity as follows:
[tex]v_{avg} = \dfrac{1}{2} (v_t + v_b)\dfrac{L_w}{t}= \dfrac{1}{2}(v_b - gt +v_b) \\ \\\dfrac{L_w}{t} = v_b - \dfrac{1}{2}gt \\ \\ v_b = \dfrac{L_w}{t }+ \dfrac{1}{2} gt\\ \\ = \dfrac{1}{t} \Bigg(L_w + \dfrac{1}{2}gt^2 \Bigg) \\ \\[/tex]
where;
[tex]v_b[/tex] = velocity gained when fallen through the height h.
Similarly, using the equation of kinematics, we have;
[tex]v_b^2 = 2gh \\ \\h = \dfrac{v_b^2}{2g}[/tex]
[tex]\implies \dfrac{(L_w + \dfrac{1}{2} gt^2_^2}{2gt^2}[/tex]
Thus, the velocity at the ground is;
[tex]v^2_{grround} = v_b^2 + 2ghb[/tex]
[tex]\mathbf{v_{ground} = \sqrt{{v^2+2ghb}}}[/tex]

A disk of known radius and rotational inertia can rotate without friction in a horizontal plane around its fixed central axis. The disk has a cord of negligible mass wrapped around its edge. The disk is initially at rest, and the cord can be pulled to make the disk rotate. Which of the following procedures would best determine the relationship between applied torque and the resulting change in angular momentum of the disk?
a. Pulling on the cord, exerting a force of 15 N for 2 s and then 25 N for 3 s, and measuring the final angular velocity of the disk
b. For five forces of different time intervals, pulling on the cord for 5 s, exerting a force of 15 N, and then measuring the angle through which the disk rotates in each case
c. For five forces of different time intervals, pulling on the cord for 5 s, exerting a force of 15 N, and then measuring the final angular velocity of the disk
d. For five forces of different magnitude, pulling on the cord for 5 s, and then measuring the final angular velocity of the disk
Pulling on the cord, exerting a force of 15 N for 2 s and then 25 N for 3 s, and measuring the final angular velocity of the disk.
What is torque?Torque is defined as the rate of change of angular momentum.[tex]\tau = \frac{dL}{dt} \\\\[/tex]
[tex]Fr = \frac{\Delta L}{\Delta t} \\\\Fr = \frac{\Delta m\omega ^2r}{\Delta t} \\\\F = \frac{\Delta m\omega ^2}{\Delta t}[/tex]
[tex]F = \frac{m\Delta \omega ^2}{\Delta t} \\\\F = \frac{m(\omega _f^2 - \omega _i^2)}{t_2 - t_1}[/tex]
where;
[tex]\omega _i[/tex] is the initial angular velocity
[tex]\omega _f[/tex] is the final angular velocity
Since the disk is initial at rest, applying a force such as 15 N gives the disk its first angular velocity and applying 25 N force for 3 seconds gives the disk its final angular velocity.

1.00 x 10^3 kg of clear liquid (specific heat
capacity = 5.11 x 10^2 J/kg-°C) at a temperature
of 15.0°C gains 3.33 x 10° J of heat. What is the
final temperature of the liquid? (Assume the
melting point is less than 15.0°C and the boiling
point is greater than 62.0°C.)
Answer:
15.00000652 °C
Explanation:
From the question,
Q = cm(t₂-t₁)................ Equation 1
Where Q = heat gained by the liquid, c = specific heat capacity of the liquid, m = mass of the liquid, t₁ = Initial Temperature of the liquid, t₂ = Final temperature of the liquid.
Given: Q = 3.33 J, c = 511 J/kg°C, m = 1000 kg, t₁ = 15°C
Substitute these values into equation 1 and solve for t₂
3.33 = 511×1000(t₂-15)
3.33 = 511000(t₂-15)
(t₂-15) = 3.33/511000
(t₂-15) = 0.0000065
t₂ = 15+ 0.0000065
t₂ = 15.00000652 °C

Design a diagram, sketch, or other model to show changes in the nucleus of an atom during nuclear fission and fusion. Include a short description and a way to compare the amounts of energy released in each event.
Fusion:
Fission:
here's the definition if it helps!
"Nuclear fission, or radioactive decay, occurs when a heavy atomic nucleus splits into smaller nuclei. For example, atoms of uranium-235 can break down into smaller particles. Some of those particles are atoms of lighter elements. The rest are neutrons."
"Nuclear fusion are reactions that occur when two small nuclei combine to form one larger nucleus. Like nuclear fission reactions, fusion reactions release very large amounts of energy."
this does not belong to me to person it belongs to their name is on this but they had already answered this question but I hope their answer helps you.
Explanation:
archanamourya726
Inside the sun, fusion reactions take place at very high temperatures and enormous gravitational pressures
The foundation of nuclear energy is harnessing the power of atoms. Both fission and fusion are nuclear processes by which atoms are altered to create energy, but what is the difference between the two? Simply put, fission is the division of one atom into two, and fusion is the combination of two lighter atoms into a larger one. They are opposing processes, and therefore very different.
The word fission means "a splitting or breaking up into parts" (Merriam-Webster Online, www.m-w.com). Nuclear fission releases heat energy by splitting atoms. The surprising discovery that it was possible to make a nucleus divide was based on Albert Einstein’s prediction that mass could be changed into energy. In 1939, scientist began experiments, and one year later Enrico Fermi built the first nuclear reactor.

If the efficiency of conversion of this energy to electricity is 50% then calculate the electricity generation capacity in kWh for a period of one year. If the cost of producing 1kWh of energy is $0.12 is it worth producing electricity from this source
Answer:
"13.48 Kwhr" is the right solution.
Explanation:
The given values are:
Average rate of heat energy,
= 0.063 W/m²
Diameter,
= 8m
Efficiency of conversion,
= 50%

Woud earth be the same after losing its gravity,,.¿and how it gets affected by others planets,,.¿
Answer:
If the earth lost its gravity we could not walk or live our normal ways
Answer:
If earth's gravity was to disappear then a lot would happen, but I believe the biggest impact on losing gravity is earth's un-stabilized core, gravity keeping earth's core stable would lead to the earth melting or would lead to its core being ripped apart into outer space, the impact on other planets its huge as well because the gravity keeps the earth in orbit and without it, earth will start roaming around the solar system bumping into planets which would lead to the entire solar system exploding.

A disk of radius 25 cm spinning at a rate of 30 rpm slows to a stop over 3 seconds. What is the angular acceleration?
B. How many radians did the disk turn while stopping ?
C. how many revolutions?
Answer:
A. α = - 1.047 rad/s²
B. θ = 14.1 rad
C. θ = 2.24 rev
Explanation:
A.
We can use the first equation of motion to find the acceleration:
[tex]\omega_f = \omega_i + \alpha t\\[/tex]
where,
ωf = final angular speed = 0 rad/s
ωi = initial angular speed = (30 rpm)(2π rad/1 rev)(1 min/60 s) = 3.14 rad/s
t = time = 3 s
α = angular acceleration = ?
Therefore,
[tex]0\ rad/s = 3.14\ rad/s + \alpha (3\ s)\\[/tex]
α = - 1.047 rad/s²
B.
We can use the second equation of motion to find the angular distance:
[tex]\theta = \omega_i t + \frac{1}{2}\alpha t^2\\\theta = (3.14\ rad/s)(3\ s) + \frac{1}{2}(1.04\ rad/s^2)(3\ s)^2\\[/tex]
θ = 14.1 rad
C.
θ = (14.1 rad)(1 rev/2π rad)
θ = 2.24 rev

1. What evidence do you see that Newton's third law applies to electrostatic forces?
Answer: The Electrostatic force of attraction or repulsion between two charges shows that the Newton's third law applies to electrostatic forces.
Explanation: Consider two Oppositely charged charges separated by distance d.
The electrostatic force exerted by charge 1 on charge 2 is.
By Coulomb's Law :
F1 = k [tex]\frac{Q1 Q2}{d2}[/tex].....................................(1)
The electrostatic force exerted by charge 2 on charge 1 is.
F2 = - k [tex]\frac{Q1 Q2}{d2}[/tex] ................................. (2)
negative sign shows that force are in opposite direction.
From Equation 1 and 2
F1 = - F2
Which implies Newton Third law.
The evidence observed from Newton's third law is that the electrostatic force of attraction exerted by two different charges will be equal in magnitude by acting opposite direction.
Newton's third law states that action and reaction are equal and opposite.
For different charges, say a positive charge (+ Q) and negative charge (-Q), the force of attraction exerted by both charges is equal and opposite.
let the positive charge, +Q = Q₁let the negative charge, -Q = Q₂From Coulomb's law, the force of attraction the two charges will exert on each other is equal and can be calculated as follows;
[tex]F_{12} = \frac{kQ_1Q_2}{r^2}[/tex]
Thus, the evidence observed from Newton's third law is that the electrostatic force of attraction exerted by two different charges will be equal in magnitude by acting opposite direction.
