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
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.
1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

The standard reduction potential for the half-reaction of Be^2+ + 2e^- -> Be is given as E^0 = 3.83 V.
For the half-cell Hg^2+ | Hg, the standard reduction potential is not provided in the given information. To calculate the electric potential for the voltaic cell, we need the reduction potential for the Hg^2+ | Hg half-cell.
A voltaic cell, also known as a galvanic cell or an electrochemical cell, is an electrochemical device that generates electrical energy through a spontaneous chemical reaction. It consists of two half-cells connected by an external circuit and a salt bridge or porous barrier that allows the flow of ions between the two half-cells.
Each half-cell consists of an electrode immersed in an electrolyte solution. The electrode is typically made of a metal or a conductive material, and the electrolyte is a solution containing ions that can participate in the redox (reduction-oxidation) reaction.

mass of silver, in megagrams, will fit in this moving truck? The density of silver is 10.49 g/mL.
_________ Mg (input numerical answer only)
Answer: The mass of silver is 1.19 X 10^14 M g
Explanation: The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.
The density of silver is 10.49 g/mL.
We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,
d= m/v where m= mass m= d x VM=10.49 g/mL X 1.138 X 10∧7 mLM=119376200 g 1 gram=10⁻⁶ Megagram 119376200= 1.19 X 10^14 Mg hence the mass of silver is 1.19 X 10^14 M g hopefully this will help you please mark me as brainlist

The water of a swimming pool is hypotonic to our cells. Explain in detail with evidence and reasoning why we do not swell and pop when we go for a swim.
Answer: Hello: ) ✨ It depends on the concentration of all solutes in the solution (ie, its osmolarity). A solution with low osmolarity is hypotonic and vice versa. Solutions having the same osmolarity are isotonic. Water in pools and rivers is hypotonic compared with sea water, but water from the Dead Sea is hypertonic.We do not swell and pop when we go swimming in a hypotonic swimming pool because our skin protects us from the external environment and does not let water cross into or out of our body surfaces. ... hope this helps have a great dayAssuming the water is warm enough that you don’t simply die of hypothermia, the next problem would be your skin. For reasons that still aren’t well understood, human skin starts to break down after continuous immersion in water of a few days. You’d suffer open sores and be liable to fungal and bacterial infections just from the spores on your skin, even if the water itself was perfectly sterile. The pressure of the water also reduces the circulation to your extremities and makes breathing more difficult.
Explanation:
A relative term, hypotonicity defines a solution's characteristic in relation to another solution.
What is hypotonic solution?The cytosolic fluid or the fluid found inside a cell is frequently used as the comparison solution in biology. Therefore, a solution would be considered hypotonic in biology if it contained fewer solutes than the cytosol of a cell. The semipermeable membrane is the cell membrane. What then occurs to a cell in a hypotonic environment.
Tonicity has the prefix "hyper," which denotes "more" or "excess." Consequently, a solution that contains more non-penetrating solutes than the other solution can pass through a semipermeable barrier.
Therefore, A relative term, hypotonicity defines a solution's characteristic in relation to another solution.

How does an increase in altitude affect the climate?
Answer:
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.

How is the form of energy being changed when a student uses an electric sharpener to sharpen a pencil?
from mechanical to electrical
from electrical to mechanical
from thermal to mechanical
from magnetic to electrical
Answer:
B
Explanation:
Because the sharpener is attached to an electrical outlet
When a student uses an electric sharpener to sharpen a pencil then from electrical energy to mechanical energy. Therefore, option (B) is correct.
What is mechanical energy?Mechanical energy can be defined as the addition of kinetic energy and potential energy that is used to perform work. The total mechanical energy is conserved when the forces performing work are conservative in nature.
The principle of conservation of mechanical energy can be described as when an isolated system is under the influence of conservative forces, then the mechanical energy is constant. If a body moves in the opposite direction of a net force, the potential energy will increase and the speed of the object changes, the kinetic energy also changes.
Many devices are used to transform mechanical energy to or from other forms of energy, such as an electric motor converts electrical energy to mechanical energy,
An electric sharpener converts mechanical energy into electrical energy. Therefore, option (B) is correct.
