Military submarines incorporate multiple technologies in order to remain silent and undetected in the water. Submarine crews are cautioned not to make loud sounds or drop tools or equipment to avoid detection. Use what you have learned about the factors that affect sound transmission to explain why submarines have to be careful not to make sounds while other military craft, such as airplanes or tanks, don't have to worry about the sounds they make? Use evidence and scientific reasoning to support your response.
Answer:
Explanation:Military submarines are designed to roam the oceans undetected by enemies or spies. They rarely surface, except to establish radio contact or perform data communication with their respective headquarters. Otherwise, their job is to be as silent as possible.
Answer
Sorry if this is incorrect, but I think the reason submarines have to stay quiet is because they want to evade discovery by passive sonar.
Explanation:
My explanation is because passive sonar detects acoustic signals and sounds which are detected because sound travels faster in water compared to air.
Hope this helps!

A chemist performs the same tests on two white solids, A and B. The results are shown in the table below.

Which result identifies the substances, A and B, correctly?
The melting point of a substance is characteristics to it. Hence, we can identify a compound by calculating its melting point. If the solids are pure they will give their characteristic actual melting point.
What is melting point?Melting point of a substance is the temperature at which it converts from solid state to liquid state where, the two phases are in equilibrium. Melting point is dependent upon the intermolecular forces, molar mass, temperature and presence of impurities.
Melting point of a pure substance is a characteristic feature for it. Hence, we can qualitatively test a compound using its melting point and using standard dats of melting points we can identify the substance.
Conductivity, solubility etc. are not characteristic for a substance and can be similar to other solids. Therefore, option A melting point tests helps to identify A and B.

Read the following passage:
Wind and water carry sand, debris, and small pieces of rocks and deposit them in layers. These layers pile up and after many years form a single rock called Rock A. The movement of tectonic plates buries Rock A deep inside Earth. Heat and pressure change the mineral composition of Rock A and transform it into Rock B. Rock B comes out to the surface of Earth due to plate movements.

Sound waves travel as particles of matter collide and transfer energy.
True
False
6
Answer:
True
Explanation:
Sound waves require a medium/substance to transmit through, for example, sound waves cannot travel through the vacuum of space . The medium, water or air, itself does not move in bulk with the wave . The medium's particles carry kinetic energy from one point to another . This is when the wave transmits through its medium, the particles simply vibrate as the wave passes through. The vibrations carry the energy from one particle to the next. This means that the sound wave is carried through the medium.
*Note: Sound waves need particles to travel but light does not.

Answer:
The stoma allows the intake of oxygen gas in photosynthesis and releases oxygen gas in respiration.
Explanation:
Through photosynthesis, leaves turn light energy into food. Through pores, or stomata, leaves “breathe” in carbon dioxide and “breathe” out oxygen. Leaves also release excess water, much like we sweat.
Choose all that apply for grasslands
No trees or shrubs
Rainfall is low
Occur in all climatic zones
Contains grasses and Woody plants
Answer:
-rainfall is low
-occur in all climate zones
-contains grasses and woody plants
The grasslands occur in all climatic zones, contains grasses and Woody plants and rainfall is low. Therefore, option B, C and D are correct.
What do you mean by the grassland ?The grassland biome is made up of broad, open grassy areas. They are kept healthy by animals that feed on them and frequent fires. There are two main types of grasslands: savannas and temperate grasslands.
Grasslands are grassy areas that are often flat, open, and continuous. In high latitudes, they are usually located between subtropical deserts and temperate forests.
Due to the environment, only grasses can thrive in grassland areas. Low precipitation rates are adequate for grasses but not for a forest of trees. Frequent fires also help to preserve grassland ecosystems. Grasses are ideal for recovering from a fire.
Thus, option B, C and D are correct.

For the following reaction:

Which of the following changes would increase the rate of the forward reaction?
Add CaO
Remove CaO
Add CO2
Remove CO2
Add CaCO3
Remove CaCO3
Increase temperature
Decrease temperature
Increase pressure
Decrease pressure
The concept Le Chatelier's principle is used here to determine the effect of change of concentration, pressure and temperature on the state of equilibrium.
What is Le Chatelier's principle?According to Le Chatelier's principle, If a system in equilibrium is subjected to a change in concentration, pressure or temperature the equilibrium shifts in the direction that tends to reduce the effect of the change.
Here adding CaO increases the rate of forward reaction. If the concentration of any reacting species is increased, the equilibrium will shift in the forward direction.
The given reaction is exothermic in forward direction. So the increase of temperature shift the equilibrium to the backward direction and the decrease in temperature shift the equilibrium to the forward direction.
Here increasing pressure will shift the equilibrium to the forward direction accompanied by a decrease in the number of moles.

The forces exerted between electric charges at a distance is evidence that each charge is surrounded by an electric field.
The forces exerted between electric charges at a distance is evidence that each charge is surrounded by an electric field.
The force exerted on an electric charge at any given distance is determined by applying coulomb's law as shown below;
[tex]F = \frac{kQ^2}{r^2}[/tex]
The electric field strength of the charge is given as;
[tex]E = \frac{F}{Q}[/tex]
F = EQ
