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
where;
E is the electric field Q is the electric chargeThus, we can conclude that the forces exerted between electric charges at a distance is evidence that each charge is surrounded by an electric field.

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!

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.

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.

Temperate grasslands have trees and shrubs
True or false
Temperate grasslands have trees and shrubs. This statement is false.
What do temperate grasslands have?Cold winters and mild, rainy summers are characteristics of temperate grasslands. Every year, grasses wither to their roots, and the soil and sod shield the roots and young buds from the winter cold or dry circumstances.
Because of the lack of rainfall, this biome may have a few trees along the streams, but not many.
The correct amount of rain and other factors aren't present in grassland ecosystems for trees to flourish, yet there is enough rain for grass to grow and cover the ground there. The length of the grass in grassland ecosystems can vary depending on the precise amount of rainfall.
Thus, Temperate grasslands do not have trees and shrubs.

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.

Why is diversity in the field of science important?
Answer:
Scientific progress relies on problem solving and collaboration. Groups composed of people with diverse experiences and areas of expertise tend to be more creative and innovative. Asking questions drives science forward, and scientists with different perspectives often ask different questions.
Explanation:
Identify the state of matter: Takes the shape of the container that it's in,
particles are very far apart, particles have high thermal energy.
The state of matter that is described is a gas; in a gas, the particles are not held together in a fixed arrangement like in a solid but are instead free to move and take on the shape of their container.
What is gas property?The state of matter being described here is gas. In a gas, the particles are not held together in a fixed arrangement like in a solid but are instead free to move and take on the shape of their container. Gas particles are very far apart from one another compared to particles in solids and liquids, which allows them to easily flow and diffuse. Gases also have high thermal energy, meaning their particles are in constant motion and collisions between particles are frequent. This results in gases expanding to fill any available space and exerting pressure on the walls of their container.
Hence, the state of matter that is described is a gas, as in a gas the particles are not held together in a fixed arrangement like in a solid but are instead free to move and take on the shape of their container.

The taxonomy is a branch of biology which classifies the living things. It was given by Carolus Linnaeus. The taxonomic ranks in order from most specific to least specific is family, order and phylum.
What is Taxonomic Hierarchy?The process of arranging different kinds of organisms into successive levels of the biological classification either in a decreasing or an increasing order from kingdom to species and vice versa is known as Taxonomic hierarchy.
Each level of the hierarchy is defined as the taxonomic category or rank. In this system of classification, Kingdom is always ranked the highest which is then followed by division, class, order, family, genus and species.
The correct order of Taxonomic Hierarchy is:
Kingdom - Phylum - Class - Order - Family - Genus - Species.
The species is the lowest level of the taxonomic Hierarchy. This can be further divided into sub-species.
