The forces exerted between electric charges at a distance is evidence that each charge is surrounded by an electric _____.
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.

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.
Which type of rock has been formed?

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

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.

How does changing the mass of a wheelchair affect its velocity?
Explanation:
Mass and velocity are inversely propotional, which means that if you increase the mass of the wheelchair the velocity would automatically decrease, similarly, if you decrease the mass of the wheelchair the velocity of the wheelchair would increase.

Why might hydrogen be a wonderful fuel for the future?
Answer:
In the future, hydrogen will join electricity as an important energy carrier, since it can be made safely from renewable energy sources and is virtually non-polluting. It will also be used as a fuel for 'zero-emissions' vehicles, to heat homes and offices, to produce electricity, and to fuel aircraft.
Answer:
It can be a wonderful fuel, because unlike other sources of power generation, it produces no greenhouse gas and hence does not contribute in polluting the environment or causing global warming. However it can be a dangerous fuel as well, as it is highly flammable.

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.

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!
