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.

write down everything that you know about heat temperature pressure and heat transfer
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:

Oil and gas are formed from the remains of microscopic ocean organisms. A student claims that the oil and gas deposits in Missouri are about 100 million years old. Based on the map, decide whether you agree or disagree with the student’s claim and then explain your decision.
Identify the main areas of North America on the map where people would expect to find 100-million-year-old sedimentary rocks that contain fossils of microscopic ocean organisms.
Answer:
I desagree with the student.
Explanation:
the part most near of U.S. is Wertern Interior Seaway, so missory is on the Easter, more specific on the Appalachia, but the mark gray not pass by the Appalachia, so this mean that Missouri is not expect to have 100 million years old of deposit of oil and gas.
compare the approximate distance from Hawaii and approximate age of the mountains in the Hawaiian–Emperor Seamount Chain. In your graph, be sure to include data from the seven mountains.
Explanation:
I don't have the data specific for this question, but I do have a general understanding of the science behind this and what the shape of this graph should look like.
The underwater mountain range and the Hawaiian Island chain were formed by a mantle plume hot spot, which is a hotter area in the mantle. Magma from the boundary between the lower mantle and inner core floated up due to its higher temperature and cooled to become a rock after reaching earth's surface, forming and island or volcano.
However, due to the movement of the Pacific Plate, this volcano moved away from its place precisely over the hot spot. Without heat from underneath, these volcanoes could no longer be active, rendering them extinct. The hot spot continued spewing lava, forming another volcano and repeating the cycle.
Over time, the rock from these volcanoes weathered and eroded away, causing them to sink under sea level and forming the mountain range and island chain.
Knowing the backstory behind Hawaii's formation, we can conclude that the islands further away from Hawaii, the biggest island with active volcanoes, are older in age.

Your concept map will compare the manner in which energy is transferred by mechanical waves and electromagnetic waves. Include the following somewhere in your concept map:
types of energy transferred
medium required (if applicable) for transfer of energy
speed of energy transfer through various mediums (solid, liquid, gas)
Explanation:
One of the various ways that energy moves through space is by electromagnetic radiation.
Electromagnetic radiation includes the heat from a blazing fire, the sun's light, the X-rays used by your doctor, and the energy used to cook food in a microwave.
Waves are recognizable to anyone who has ever gone swimming in the ocean.
Electromagnetic waves are similar, however they differ in that they are made up of 222 waves that oscillate perpendicular to one another.
An oscillating magnetic field is one of the waves, while an oscillating electric field is the other.
Mechanical waves travel in a vacuum, whereas electromagnetic waves travel in a vacuum. Mechanical waves require the assistance of a medium to travel and can only travel at the speed of that medium whereas electromagnetic waves can pass through any medium.
