Can someone answer this question about Compton effect?

The correct answer is c. The exponential decay constant's value is [tex]2.6*10^{-55 }s^{-1}[/tex].

To find the value of the exponential decay constant, we need to calculate Ks, the thermal conductivity of the sample. We employ the equation to arrive at this. [tex]Ks = mc + mow[/tex],

where m is the mass of Polly, c is the specific heat of the human tissues, and mow is the mass of the water. Plugging in the values for Polly's mass (60 kg), the specific heat of the human tissues (3500 J/(kg°C)) and

the mass of the water (300 kg),

and the specific heat of the water (4186 J/(kg°C)),

we get Ks = 0.5 W/(m°C).

Now, we can plug in the values for Ks, A, I, and Ax into the equation for[tex]Tdif = (constant) e^{-t}[/tex]

to calculate the exponential decay constant. By entering the values, we obtain the equation.

[tex]Tdif = (constant) e^{-t} = (0.5 W/(mC) * 2nrl * 1.5 m * 0.5 m) e^{-t}.[/tex]

Simplifying, we get  [tex]Tdif = 2.6*10^{-55} e^{-t}.[/tex].

Therefore, the value of the exponential decay constant is  [tex]2.6*10^{-55 }s^{-1}[/tex].

Answer:

A

Explanation:

Momentum change is basically impulse

Object possessing more velocity after bouncing OR the object which bounces more have more impulse

When a skydiver falls, air resistance, or drag, is the force that acts in the opposite direction to gravity.

As the skydiver falls through the atmosphere, air molecules collide with their body, creating a force that opposes the direction of motion. The magnitude of the air resistance force depends on the speed of the skydiver, the surface area of their body, and the density of the air.

Initially, when the skydiver jumps out of the plane, the force of gravity pulls them downward, and they start accelerating towards the ground. As they gain speed, the air resistance force gradually increases until it becomes equal in magnitude to the force of gravity. At this point, the skydiver stops accelerating and falls at a constant velocity, known as the terminal velocity.

The air resistance force is proportional to the velocity of the skydiver, which means that increasing the velocity increases the air resistance force. At high velocities, the air resistance force becomes so strong that it eventually overcomes the force of gravity, allowing the skydiver to slow down and eventually land safely on the ground.

Acceleration is defined as the rate at which velocity changes with time.

There are two types of velocity which includes:

Average velocity: This is the average rate of change of position of particles with respect to time over an interval.

Instantaneous velocity: This is defined as the specific rate of change of position with respect to time at a particular point.

The situation that will make the average velocity and the instantaneous velocity vectors to be equal or identical is when acceleration is equal to zero.

Answer:

The object's speed is 3 meters per second.

Explanation:

The impulse is  force × time. Option D

In physics, impulse is a quantity that describes the change in momentum of an object that results from a force acting on it for a period of time. Mathematically, impulse is defined as the product of force and the time interval over which it acts:

Impulse = force × time

The unit of impulse is the newton-second (N·s) in the SI system of units.

Impulse is closely related to the concept of momentum, which is the product of an object's mass and velocity. When a force acts on an object, it causes a change in the object's momentum. The magnitude of this change is equal to the impulse that the force imparts on the object.

The power of x is the exponent of x in an equation. The power of x (x^n) is the result of multiplying a number (x) by itself (n) times. For example, in an equation of the form x^a, the power of x is a.

For example, if x = 2 and n = 3, then x^n = 8 (2 x 2 x 2).

The Excel equation is similar to the equation V=kQ/d in that they both contain variables (x, k, Q, and d) and the goal is to calculate a result (x^n, V). However, the Excel equation is specific to the power of x and is used to calculate the result of multiplying a number by itself a certain number of times. The equation V=kQ/d is used to calculate velocity based on a constant (k), a quantity (Q), and a distance (d). However, the equation V=kQ/d does not involve x, and it is used to calculate the voltage, V, in a circuit. The power of x is simply a mathematical notation used to indicate the number of times a variable is multiplied by itself, while the equation V=kQ/d is used to calculate the voltage in a specific circuit.

the stone's final speed just before hitting the ground is: v = √(2 × 9.81 × 90) m/s = √(1765.8) m/s = 42.0 m/s.

a) the magnitude of the force parallel to surface 1 is 6.13 N

b) the magnitude of the force parallel to surface 2 is 4.02 N.

The gravitational force acting on each object is given by F = m * g

where m is the mass of the object

and g is the acceleration due to gravity (g = 9.8 m/s^2 on the surface of the earth).

Let's call the force parallel to surface 1 F1, and the force parallel to surface 2 F2.

a) To calculate the magnitude of F1:

F1 = m1 * g * cos(angle of elevation of surface 1)

m1 = .800 kg (mass of object on surface 1)

angle of elevation of surface 1 = 40 degrees

F1 = .800 kg * 9.8 m/s^2 * cos(40) = 6.13 N (approx.)

b) To calculate the magnitude of F2:

F2 = m2 * g * cos(angle of elevation of surface 2)

m2 = .500 kg (mass of object on surface 2)

angle of elevation of surface 2 = 55 degrees

The time it takes for the piano to reach the bottom of the ramp can be calculated using basic kinematic equations. First, we must find the initial velocity of the piano as it starts down the ramp. This can be calculated using the formula v = gsinα, where v is velocity, g is the gravitational acceleration (9.81 m/s2 on Earth), and α is the angle of the incline (in this case 28°).
Using this equation, we get an initial velocity of 3.83 m/s.
Next, we need to find the distance that the piano will travel before it reaches the bottom of the ramp. This can be calculated using the formula d = 1/2 gt2, where d is distance, g is the same gravitational acceleration, and t is the time it takes for the piano to reach the bottom of the ramp.
Plugging in our initial velocity from before, we can rearrange the equation to solve for t. We get t = √(2d/g), where d is the distance that the piano needs to travel (in this case, 1.3 m). Plugging in our values, we get a time of 1.29 seconds.

Answer:

The mathematical expression for the quantization of energy in a system described by the Schrödinger equation is given by the eigenvalue equation:

HΨ = EΨ

Where H is the Hamiltonian operator, Ψ is the wave function, and E is the eigenvalue that represents the quantized energy of the system.

The concept of quantized energy levels in an atom is related to the quantization of energy in the Schrödinger equation. In quantum mechanics, atoms can only exist in certain energy levels or states, which are determined by the solutions to the Schrödinger equation. These energy levels are quantized, meaning that the energy can only take on specific values, and not any value in between. This results in the characteristic spectra of atomic systems, where the electrons in an atom can only transition from one energy level to another by absorbing or emitting a photon with an energy that corresponds to the difference in energy between the two levels.

In summary, the quantization of energy in a system described by the Schrödinger equation is the foundation for the concept of quantized energy levels in atoms, which has important implications for our understanding of the behavior of atoms and the properties of materials.

The energy of a wave is proportional to the square of its amplitude. Doubling the amplitude of a wave quadruples its energy.

Therefore, if the original wave on the small lake had an amplitude of 0.1 meters and a certain amount of energy, doubling its amplitude to 0.2 meters would increase its energy by a factor of 4. In other words, the energy of the wave would become 4 times greater than its original value.

The largest deviation a wave can make from its equilibrium position is referred to as its amplitude. In plainer terms, it refers to the height of a wave, or the distance between the highest point (the wave's crest) and the lowest point (its trough).

A wave's energy, or the entire amount of work that the wave may exert on its surroundings, is measured by the amplitude of the wave. The wave carries more energy the larger its amplitude.

The term "amplitude" is frequently used to describe a variety of waves, such as sound, light, and water waves. It is typically expressed as a "A" sign and is measured in units of measurement like meters or feet.

To calculate the energy of the wave by doubling its height:

(Energy after / Energy before) = (Amplitude after)^2 / (Amplitude before)^2

Substituting the given values, we get:

(Energy after / Energy before) = (0.2)^2 / (0.1)^2 = 4

This means that the energy of the wave after doubling its amplitude would be four times the energy of the original wave.

So, if the original wave had an energy of E, the energy of the wave after doubling its amplitude would be 4E.

The cylinder rolls on the plane without slipping, and the string is parallel to the plane. Assume the cylinder has a radius of R and an inertia moment about its center of mass of I.

Tension in the string (T), the gravitational force on mass m (mg), and the frictional force on the cylinder from the plane are the forces acting on the system (f).

The tension in the string (T) is balanced by the gravitational force on mass m because the string is parallel to the plane (mg). As a result, we can write:

T = mg

To find the acceleration of mass m, we can use Newton's second law for the vertical motion of mass m:

mg - T = ma

Substituting T with mg, we get:

a = g - g(M/m)

where M/m is the ratio of the masses of the cylinder and the mass, respectively.

To find the condition on the ratio M/m for which the cylinder accelerates down the plane, we need to apply Newton's second law for the rotational motion of the cylinder. The torque acting on the cylinder is due to the frictional force f, which is given by:

f = μN

where μ is the coefficient of static friction, and N is the normal force on the cylinder from the plane. Since the cylinder rolls without slipping, the frictional force f is equal to the force due to the tension in the string, which is mg.

Therefore, we can write:

mg = f = μN

The normal force N is equal to the weight of the cylinder, which is Mg. Therefore, we can write:

mg = μMg

Simplifying, we get:

μ = m/M

For the cylinder to accelerate down the plane, the frictional force must be less than or equal to the maximum static frictional force, which is given by:

f_max = μ_s N

where μ_s is the coefficient of static friction. Therefore, we need to have:

f <= f_max

Substituting f and f_max, we get:

mg <= μ_s Mg

Substituting μ = m/M, we get:

mg <= μ_s Mg

Simplifying, we get:

m/M <= μ_s

Therefore, the condition on the ratio M/m for which the cylinder accelerates down the plane is:

M/m > μ_s

where μ_s is the coefficient of static friction between the cylinder and the plane.
