On a particle level, what happens when thermal conduction occurs within a liquid?

Answer:

a) When fast particles rise to the top.

Explanation:

Heat is a form of energy that can be studied through the thermal agitation of the molecules that a material involves. When heat is delivered to a body, its temperature increases, the mobility of its molecules increases. In this way, the system is not in thermal equilibrium: the temperature at each point of the body is different and the variations over time.

There are three forms of heat transmission: conduction, convection and radiation. In conduction, heat is transferred only because of molecular movement and shocks between fast and slow molecules, without displacement of matter. Convection is due to the global movement of matter and is only important in liquids and gases. Radiation is an electromagnetic interaction between bodies and does not require the existence of a material means to transmit heat from one to another. The conduction of heat in a medium can be more or less favorable according to the material.

Sherlock Holmes examines a clue by holding his magnifying glass (with
Alborosie

Answer:

Distance: -30.0 cm; image is virtual, upright, enlarged

Explanation:

We can find the distance of the image using the lens equation:

\frac{1}{f}=\frac{1}{p}+\frac{1}{q}

where:

f = 15.0 cm is the focal length of the lens (positive for a converging lens)

p = 10.0 cm is the distance of the object from the lens

q is the distance of the image from the lens

Solving for q,

\frac{1}{q}=\frac{1}{f}-\frac{1}{q}=\frac{1}{15.0}-\frac{1}{10.0}=-0.033\\q=\frac{1}{0.033}=-30.0 cm

The negative sign tells us that the image is virtual (on the same side of the object, and it cannot be projected on a screen).

The magnification can be found as

M=-\frac{q}{p}=-\frac{-30}{10}=3

The magnification gives us the ratio of the size of the image to that of the object: since here |M| = 3, this means that the image is 3 times larger than the object.

Also, the fact that the magnification is positive tells us that the image is upright.

A mass m is attached to an ideal massless spring with spring constant k. In experiment 1 the mass oscillates with amplitude a, a
JulijaS [17]

The experiment's time period is unaffected by the change in amplitude in either experiment.

<h3>What are the variables that affect time in SHM?</h3>

The time frame is provided by:

$T=2 \pi \sqrt{\frac{m}{k}}$

where,

T = Time period.

M = mass.

k = spring constant.

We can see from the formula above that the only factors affecting the time period in a Simple Harmonic Motion (SHM) are the object's mass and spring constant. Any changes in the object's mass or the spring constant will cause the time period to adapt.

<h3>Describe the Spring Constant.</h3>

The attribute is known as a spring's "spring constant" describes the relationship between the force acting on a spring and the displacement it causes. In other terms, it describes the stiffness and size of a spring's range of motion.

My predicted height was lower than the final height i measured. this is because friction slowed the puck as it was sliding along
LekaFEV [45]

I disagree since friction will cause the ultimate height to be lower than what was anticipated. To reduce the height, resist the action.

<h3> What is the height?</h3>

The vertical distance between an object's top and the bottom is defined as its height.

It is measured in centimeters, inches, meters, and other units. The height of the cliff is obtained by the Newton equation of motion.

My actual height was less than what I had anticipated. this is because the puck's movement along the track was impeded by friction.

To the Khalida, I object. Disagree, since friction will cause the ultimate height to be lower than the anticipated height. To reduce the height, resist the action.

Hence, I disagree with Khalida.

To learn more about the height, refer to the link;
