a netrual atom of helium has 2 protons and ____ eletrons ( enter whole number )
Answers
The answer is 2
The picture I put might explain it but if not. I think it’s because since there is 2 protons there should be 2 electrons to keep it equal?
Answer:
a neutral atom of helium has 2 protons and 2 electrons

what is the definition of inertia? (picture down below)
Answers
Answer:
A
Explanation:
A tendency to do nothing or to remain unchanged.
A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
Explain- inertia is typically defined as An object in motion will stay in motion unless interacted upon by an unbalanced force. Meaning an object will not change it to motion until something gets in its way.

Why is it less noisy stomping on carpet than stomping on tile floors?
Answers
Answer:
Carpet softens harsh sounds and creates a quieter, more peaceful indoor environment. The installation of carpet and underlay is the only method available for eliminating excessive noise generated by floor impacts such as noise produced from footfalls, chairs scraped across the floor and objects dropped on the floor.

Carpets are thicker. That's why when you stomp it's more quieter because the impact of your foot will hit the thickness.

write down everything that you know about heat temperature pressure and heat transfer
Answers
Answer:
Heat is always transferred from the object at the higher temperature to the object with the lower temperature. For a gas, the heat transfer is related to a change in temperature. The temperature, pressure, and volume of the gas determine the state of the gas. Heating a gas changes the state of the gas.
Explanation:
This is something I know about heat temperature pressure and heat transfer
The object with the higher temperature always transfers heat to the thing with the lower temperature. The heat transfer for gas is connected to a temperature change.
What is meant by heat transfer?Heat transfer is defined by thermodynamic systems as "The transfer of heat over the system boundary caused by a temperature difference between the system and its surroundings."There are several ways for heat to go from one place to another. The many heat transmission mechanisms consist of:Conduction: Thermal energy is transferred from an area with higher kinetic energy to an area with lower kinetic energy. Slow-moving particles gain kinetic energy as a result of collisions between high-speed and slow-moving particles. This common type of heat transmission occurs when two objects physically touch. Convection: The flow of fluid molecules from higher temperature regions to lower temperature regions is referred to as convection.Radiation: Radiant heat is the name for thermal radiations. Emission of electromagnetic waves results in the production of thermal radiation. The energy from the producing body is removed by these waves. A vacuum or transparent media, which can be made of solid or liquid, is used for radiation transmission.To learn more about heat transfer, refer to:

Answer:
Radio waves and the are various frequencies of radio waves are used for television and FM and AM radio broadcasts, military communications, mobile phones, ham radio, wireless computer networks, and numerous other communications applications. They are important because Radio waves are very widely used in modern technology for fixed and mobile radio communication, broadcasting, radar and radio navigation systems, communications satellites, wireless computer networks and many other applications.
Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication. They are important because microwaves play an increasingly wide role in heating and cooking food. They are absorbed by water and fat in foodstuffs (e.g., in the tissue of meats) and produce heat from the inside. In most cases, this reduces the cooking time a hundredfold.
