897 m/s
0.19 m/s
41 m/s

Answers

Answer 1
Answer: 5.3 m/s
-------------------------------
Answer 2
Answer: The answer to this is 5.3 cause if you divide both of 69 and 13 it equals 5.3

Double Displacement Reaction

An element from each of two compounds switch places.
Example: compound + compound ⇒ compound + compound

Chemical reactions are processes in which substances change into other substances. A chemical reaction takes place if one or more of these occur:
Color changes - Different combinations of molecules reflect light differently. A color change indicates a change in molecules.
Heat content changes- In all chemical reactions, the heat content of the reactants and the heat content of the products is never the same. Sometimes the difference is great and can be easily detected. At other times, the difference is slight and more difficult to detect.
Gas produced - Whenever a gaseous product forms in a liquid solution, bubbles can be seen. A colorless gas produced in a reaction of solids is much harder to detect.
Precipitate forms- Precipitates are insoluble products formed by a reaction taking place in a liquid solution. This insoluble product will eventually settle to the bottom, but might immediately appear by turning the clear solution cloudy.

Endothermic.

Which type of waves is important to have for a surfer who wants to do aerial maneuvers? A. Plunging waves B. Surging waves C. Orbital waves D. Spilling waves

Answers

Plungingwaves is important to have for a surfer who wants to do aerial maneuvers.

The correct options is A.

What is a plunging wave?

When the ocean floor is steep or has abrupt depth changes, crashingwaves occur. They could be large close-outs or strong barrels. Combining pouring and plungingwaves creates a collapsing wave.

What causes plunging waves to form?

When the incoming surf strikes a steep ocean floor or a sea bottom with abrupt depth changes, plungingwaves are created. The wave's peak curves over and erupts on the trough as a result. A crashing sound is frequently audible due to the compression of the airbeneath the wave's lip.

Aerial maneuvers in surfing demand taking the surfboard into the air. The best type of waves for such maneuvers are:

- the section of a wave coming towards you should be  smaller than the section you are on

- you should try to find closeout sections of waves (  formations that do not allow a tubular ride )

- the wave should be either wedging or bowling in towards you, it should not be a straight wave.

People working in nuclear plants wear special monitoring devices to track their exposure to radiation. Radioactive materials used in plants emit particles but they also emit high energy waves that are potentially lethal to human life. These waves are ______ waves

Answers

Answer:

Gamma rays

Explanation:

Gamma rays are usually defined as a type of electromagnetic radiations, that are characterized by the presence of shorter wavelength and higher energy. These are the common radiations that are released from the radioactive substances, where an unstable nucleus of an atom releases an excess amount of energy by undergoing continuous electromagnetic processes.

These are harmful to humans and other organisms, as they are comprised of very high energy and they can easily penetrate through the bodies of humans and other organisms.

These gamma particles are emitted in the power plants, where the people working in it wear a special type of device that helps them in monitoring the exposure to radiation.

It could also be gamma rays i don't really know

Answers

Heat energy is the energy of the motion or vibration of molecules in a substance. The answer is letter A. A wrecking ball on its way down before it hits a building is an example of kinetic energy being converted into mechanical energy. The answer is letter D.

The answer to the first question is A. Heat, because in order to heat up or catch fire, the molecules have to vibrate quickly.

This wrecking ball is an example of potential energy being converted into kinetic energy, so your answer is B. potential, kinetic.

What are electron orbitals

Answers

Answer:

Electron orbitals are energy levels or shells that an electron inhabits in an atom or a molecule. The number of orbitals in an atom depends on the number of protons in its nucleus. The electrons fill the orbitals from lowest to highest energy. The arrangement of electrons in the orbitals determines the behavior and properties of the atoms and molecules.
