What does a seismograph record?
A. the distance from the epicenter of an earthquake
B. the vibrations produced by an earthquake
C. the amount of damage that results from an earthquake
D. the total amount of energy released by an earthquake
Answers
1. Magnitude measures the energy released by the earthquake, while intensity measures its duration. The correct option is A.
2. The conclusion you can draw between the two conditions is that there is more likely to be an earthquake in a "highest hazard" location than in a "lowest hazard" location and is denoted as option A.
3. P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.
4. Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network.

B. Desert canyons collect all water and funnel it out of the desert.
C. Desert lakes absorb all the water.
D. Mountains block the winds that bring rain clouds.
Answers
Answer:
As I'm Not % Sure I Can Say C & D don't seem Right, Leaving A & B Having Me to Think the Answer is A (Hope I'm Right Good-Luck)
Explanation:
Answer: Mountains block the winds that bring rain clouds.
Explanation: By acting as obstacles to the flow of air masses, mountains contribute significantly to the dryness of deserts. Orographic lifting is a process that occurs when moist air is forced to ascend as it approaches a mountain range. The moisture in the air condenses and forms clouds as the air cools as it climbs. As a result, on the windward side of the mountains, the air loses a lot of its moisture as precipitation. The air has already lost a significant amount of moisture by the time it reaches the leeward side of the mountains, creating a rain shadow effect. On the leeward side of the mountains, this impact results in a dryer area that is often a desert. Consequently, the existence of mountains influences
Develop models bonds can be placed on a scale that ranges from 100% ionic to 100% covalent. Use what you know about the types of bonds that specific elements tend to form to place each of the following compounds in the correct location on the scale: CO2, N2 , NaF, H2O
Answers
Answer:
Bonds can be placed on a scale that ranges from 100% ionic to 100% covalent.
CO2: CO2 is a covalent compound, with each carbon atom sharing electrons with two oxygen atoms. Therefore, it can be placed closer to the 100% covalent end of the scale.
N2: N2 is a covalent compound, with each nitrogen atom sharing electrons with another nitrogen atom. Therefore, it can be placed closer to the 100% covalent end of the scale.
NaF: NaF is an ionic compound, consisting of a sodium cation (Na+) and a fluoride anion (F-). Therefore, it can be placed closer to the 100% ionic end of the scale.
H2O: H2O is a polar covalent compound, with the hydrogen atoms sharing electrons with the oxygen atom, but the electrons are not shared equally, therefore the oxygen atom has a partial negative charge and hydrogen atoms have a partial positive charge. Therefore, it can be placed closer to the middle of the scale, between ionic and covalent.
Overall, the scale can be represented as follows:
100% Ionic <-------> NaF <-------> H2O <-------> CO2 <-------> N2 <-------> 100% Covalent

Witch statement correctly compares the masses of subatomic particles in an atom such as carbon
Answers
Answer: The statement that correctly compares the masses of subatomic particles in an atom such as carbon is "The mass of a neutron is slightly larger than the mass of a proton, and the mass of an electron is much smaller than that of a proton or neutron." This is because an atom such as carbon is composed of protons, neutrons, and electrons. Protons and neutrons are approximately the same mass and are much more massive than electrons. Therefore, the mass of a neutron is slightly larger than the mass of a proton, and the mass of an electron is much smaller than that of a proton or neutron.

Answer:
C
Explanation:
PROTON AND NEUTRON HAVE SAME MASS . WHILE PROTON HAS APPROXIMATELY 1869 TIMES MORE MASS THAN ELECTRON

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s
kinetic energy is given as
