Answer:
By definition, air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air. These drag forces act opposite to the oncoming flow velocity, thus slowing the object down.
Explanation:
He should add ten more dots so that all thirteen electrons are shown.
He should add a single dot below the symbol.
He should add one dot below and one dot to the left of the symbol.
Since Sal drew the electron dot diagram of an aluminum atom, Sal should;
C. He should add a single dot below the symbol.

3. The Earthquake occured on the other side of the Earth
Explanation:
One of the main difference between P-waves and S-waves is that P-waves can travel through solids and liquids, while S-waves can only travel through solids. They are not able to travel through liquids.
So, if a seismic station showed only P waves, it means that there was some area in liquid state between the seismic station and the hypocenter of the earthquake. Inside the Earth, the outer part of the core is made of liquid, so this means that there outer core was along the line connecting the seismic station and the hypocenter and "blocked" the S-waves: therefore, the earthquake occurs on the other side of the Earth.
4. In order to determine with precision the location of the epicenter
Explanation:
One seismic station is only able to determine the distance of the epicenter - so, by using one seismic station only, we are only able to tell that the epicenter is located on a point along a circle, centered around the seismic station.
If we use two seismic station located at different points, we can draw two circles of possible locations for the epicenter, one for each seismic station. The intersection between the two circles will give us the exact location of the epicenter. However, two circles have two intersections: therefore, there is still an ambiguity concerning the exact location of the epicenter.
If we use three stations, therefore, we can draw three circles, and they have one intersection only: this intersection will give us the exact location of the epicenter.
Answer:
1. P waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth. For example, if an earthquake occurs on one side of Earth, seismometers around the globe can measure the resulting S and P waves.
2. P waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth. For example, if an earthquake occurs on one side of Earth, seismometers around the globe can measure the resulting S and P waves.
3. If a seismogram records P-waves and surface waves but not S-waves, the seismograph was on the other side of the Earth from the earthquake because those waves cannot travel through the liquid core of the earth.
4. Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Knowing this helps them calculate the distance from the epicenter to each seismograph.
5. As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.
If you are talking about volume, then an easy way to measured the volume of a liquid would be with a graduated cylinder. A graduated cylinder is marked with volume units such as milliliter (mL) or the liter (L). One liter equals 1 thousand milliliters.
To measure the volume of a solid you use the formula V = (Length)(Width)(Height)
To measure the volume of a gas you use a graduated cylinder held upside down. At first the cylinder is filled with water. When air is blown into the cylinder, bubbles rise and push some water down. The volume of the water pushed down is equal to the volume of the gas that was blown in.
Answer: Increase internal energy and work done by the system
Explanation: According to the first law of thermodynamics conservation of energy, when heat is added to the system then the system gain or loss of energy.
So, when we add heat to a system then increases internal energy and external work done by the system.
temperature rises ? specific heat capacity etc ...
Answer:
C. The final kinetic energy is equal to the initial potential energy.
Explanation:
Based on the Principle of energy conservation:
Sum of the Initial Energy = Sum of the Final Energy
Initial Kinetic Energy + Initial Potential Energy = Final Kinetic Energy + Final Potential Energy..........(1)
Since according to the question:
Initial Kinetic Energy = 0
Final Potential Energy = 0
The equation (1) above reduces to
Initial Potential Energy = Final Kinetic Energy
