How you can prevent thermal energy from moving by conduction, convection, and radiation?
Answer:
Using insulating materials is the best way to prevent heat transfer by conduction and convection. Insulating materials are poor conductors of thermal energy and also limit the movement of air in spaces, reducing convection. Insulation slows the rate at which unwanted energy enters the home in the summer.
Explanation:
Easy peasy.
One can prevent thermal energy from moving by conduction, convection, and radiation by using insulating material.
What is thermal energy?Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy.
What is conduction?Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules.
What is convection?Convection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid.
What is radiation?Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium.
What is insulating material?There are two types of insulating materials: radiant barriers and reflective insulation systems.
Insulating materials are poor conductors of thermal energy and also limit the movement of air in spaces, reducing convection.

Answer:
I believe the answer is Particles
Explanation:
let me know if i'm wrong
Isaac Newton believed that light was made of particles.
What is light?Light or visible light is electromagnetic radiation that can be perceived by the human eye.Visible light is usually defined as having wavelengths in the range of 400 – 700 nanometers (nm), corresponding to frequencies of 750 – 420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths)Given is the theory of light by Sir Isaac Newton.
Corpuscular Theory →
According to Newton's corpuscular theory of light, light is composed of very tiny, elastic and rigid particles called corpuscles. When this corpuscles enters into our eye, we get the sensation of light or sensation of vision.Therefore, Isaac Newton believed that light was made of particles.

In one ride, there are two identical roller coaster cars (orange and green) that start on opposite sides of a large magnet located at the center of a station. Shanika wants to get the largest increase in potential energy she can by moving one car one space to the left or the right.
Shanika can move the orange car to point A or point B, or she can move the green car to point C or point D. Which movement should she make? Why will that movement result in the largest increase in potential energy? Describe the magnetic force that will act on the roller coaster car she moves.

A student has designed a circuit with one battery, two light bulbs, and two switches, pictured to the left. She would like for each switch to control one light bulb, so that when one switch is open and the other is closed, one of the light bulbs will remain lit. From the image, we can see that neither light bulb is lit, even though one of the switches is closed. What is the error the student made? Your explanation should include a discussion of the flow of electrons in the circuit.
Answer:
The bulb is not powered because the negative end of the battery is not connected to the electric current,making it dysfunctional. The electrons have to flow through the positive and negative ends of the battery in order for it to work.
Hope this helps.
The mistake of the student is that the circuit was left open hence current can not flow across in the circuit.
What is a circuit?A circuit is designed for the flow of current. In this case, we know that current can only flow when the circuit is closed. A closed circuit implies that the switch has been closed.
