If the average rate of sediment accumulation is 3 cm/1000years, how long would be required for sediments to completely bury seamounts 1.5 km high and convert part of the oceanic ridge into a part of the abyssal plains. (Show your work).
Answer:
500,050000 years
Explanation:
Given that :
Rate of Accumulation = 3cm/ 1000 years
Height of seamounts = 1.5km
Representing height of seamounts in cm;
(1.5 *1000 * 100) = 1500150 cm
Time taken = height / rate
Time taken = (1500150 cm / 3cm) * 1000
Time taken = 500,050000 years
Illustrating Mechanical Waves
TASK: Create a collage to describe and illustrate how a medium may move and transfer energy in a transverse and compressional/longitudinal wave.
Mechanical waves are waves that transfer energy through a medium (matter). The medium can be a solid, liquid or a gas. A medium in a mechanical wave can move transversely , in a surface wave or Longitudinally. Illustrate the medium movement in a transverse wave and in a compression wave. Below is a checklist/guide for how you will be evaluated for this task.
Illustrate a transverse wave that progressively changes with at least 3 distinguishable
properties: Maximum Points: 60
Labels the crest and the trough.
Labels a point at which the energy of the wave is high.
Labels a point at which the energy of the wave is low.
Label the amplitude, wavelength and identify the frequency of the wave
Draw an arrow to indicate the direction that the medium moves.
Draw an arrow to indicate the direction that the wave moves.
Provides description of your wave in terms of wavelength (long, short), frequency (high, low and the amount in Hertz-Hz) amplitude (high, low)
Identify a measured wavelength and amplitude.
Lastly, have a title and the definition of a transverse wave.

Transverse wave:
⇨- the way the wave is moving
⟶- Medium - the material it is traveling through
冖- Wavelength - the distance from crest to crest
C - Crest - the highest point on a wave
T - trough - the lowest part on a wave
↕️ - Amplitude - the distance from rest to crest
ྊ - (tinfoil)Wave
Description:
In the beginning of the wave the wavelength is short and the frequency is high so is the energy.and the amplitude is low *i believe* And after the mark of T shown on the image the wavelength is long and the frequency is low and so is the energy and the amplitude is high *i believe*.Amplitude and wavelength are both measures of distance.
Longitudinal/Compressional Wave:
KEYS:
⟶-medium - the material it is traveling through
⇨-way the wave is moving
冖-wavelength - the distance from crest to crest
R -Rarefaction - the opposite of compression
C-Compression - particles are closest together

each compound or molecule is indicated in subscript next to the compound by an abbreviation in parentheses. For example, a compound in the gas state would be indicated by (g), solid (s), liquid (l), and aqueous (aq).
Explanation:
Fill in the chart with the following words:
- Potential energy
- kinetic energy
- Chemical energy
- Joules
- Energy
- thermal energy
Answer:
Energy
potential energy kinetic energy
chemical energy thermal energy
joules
Explanation:
chemical energy is a type of potential energy or stored energy. Heat is a kinetic energy and energy is measured in joules.
The first box is energy. It can be divided into kinetic energy in one side and potential energy in the other side. Here, kinetic energy can be converted to the thermal energy and potential energy can be converted to chemical energy. They are measure in Joules.
What are various forms of energy ?Potential energy and kinetic energy are two forms of energy that are commonly encountered in physics.
Potential energy is energy that an object possesses due to its position, shape, or state. An object can store potential energy when it is moved away from its equilibrium position, such as when a spring is stretched or a book is lifted to a certain height above the ground.
The amount of potential energy an object has is proportional to its mass, height, and the strength of the force that is acting on it. The average kinetic energy of an object is called its thermal energy.
Therefore, first box is energy. It can be divided into kinetic energy in one side and potential energy in the other side. Here, kinetic energy can be converted to the thermal energy and potential energy can be converted to chemical energy. They are measure in Joules.

. 2. Which has more atoms: 2.5 mol of calcium carbonate,
CaCO3, or 3.5 mol of calcium hydroxide, Ca(OH)2
Answer:
Calcium hydroxide has more atoms.
Explanation:
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number applies to any substance.
Then you can apply the following rules of three:
If 1 mole of calcium carbonate represents 6.023*10²³ atoms, 2.5 mole of calcium carbonate represents how many atoms?[tex]amount of moles of calcium carbonate=\frac{2.5 moles*6.023*10^{23} atoms}{1 mole}[/tex]
amount of moles of calcium carbonate= 1.50575*10²⁴
If 1 mol of calcium hydroxide represents 6.023*10²³ atoms, 3.5 mol of calcium hydroxide represent how many atoms?[tex]amount of moles of calcium hydroxide=\frac{3.5 moles*6.023*10^{23} atoms}{1 mole}[/tex]
amount of moles of calcium hydroxide= 2.10805*10²⁴
2.10805*10²⁴ is greater is 1.50575*10²⁴, so calcium hydroxide has more atoms.

No link or Files plz i need help with this one i been stuck on it for a long time
Answer:
The particles in a solid are tightly packed and locked in place. Although we cannot see it or feel it, the particles are moving or vibrating in place.
Answer:
molecules in a solid are tightly packed together and vibrate about their fixed positions.
Explanation:
there is very little movement between molecules in a solid since there is not much space between the molecules, hence the slight vibrations.

Solve,55.1 grams of tin at 90.6°C is dropped into a calorimeter with 75.4 grams of water at 21.0°C.The temperature of both the metal and the water reaches 27.2°C.Solve for the specific heat of tin. pleaseee once u solve it please explain how u solved it.
Answer:
[tex]C_{tin}=0.560\frac{J}{g\°C}[/tex]
Explanation:
Hello there!
In this case, for this calorimetry problem, we can notice that the heat evolved by the hot tin is gained by the cold water as the calorimeter is perfectly isolated, so we can write:
[tex]-Q_{tin}=Q_{water}[/tex]
Thus, by defining the heats in terms of mass, specific heat and temperatures, we get:
[tex]-m_{tin}C_{tin}(T_F-T_{tin})=m_{water}C_{water}(T_F-T_{water})[/tex]
Now, since we are asked for the specific heat of tin, we solve for it as shown below:
[tex]C_{tin}=\frac{m_{water}C_{water}(T_F-T_{water})}{-m_{tin}(T_F-T_{tin})}[/tex]
Thus, when we plug in, we obtain:
[tex]C_{tin}=\frac{75.4g*4.184\frac{J}{g\°C} (27.2\°C-21\°C)}{-55.1g(27.2\°C-90.6\°C)}\\\\C_{tin}=0.560\frac{J}{g\°C}[/tex]

how would you revise the stimulation so users can evaluate the role of human activity in the pH of the ocean
Answer:
Explanation:
If only one parameter can be changed in the simulation, it would be the global temperature. Human activities cause global warming and the temperature rise has caused the polar ice cap to melt. With more fresh water going into the oceans due to melting ice cap, there is a big impact on the pH.
Answer:
Explanation:
increase CO2 in atmosphere - human activity like driving cars n burning fossil fuel releases air polluntants. CO2, NOx n SO2 are all soluble in water n form acids. of the 3, CO2 is the most common pollutant n has the most effect on the pH in oceans.

9. A student needs to prepare 100 mL of a 0.50 M ammonium chloride, NH4Cl,
solution. How much solute does he need?
Answer:
2.67g of NH4Cl are required
Explanation:
Molarity is an unit of concentration in chemistry defined as the moles of solute (In this case, NH4Cl), per liter of solution.
To prepare 100mL of a 0.50M are required:
100mL = 0.100L * (0.50 moles / L) = 0.0500 moles NH4Cl
As molar mass of NH4Cl is 53.491g/mol:
0.0500 moles * (53.491g / mol) =
2.67g of NH4Cl are requiredWhich one of your body cells carries proteins that determine your blood type?

-because not enough of the daughter product has formed to be detectable
-because neither the parent isotope nor the daughter product will be detectable

0.75 moles of an unknown acid are dissolved in water. If 0.42 moles of H3O+ form, what was the percent dissociation of the unknown acid?
Answer:
56 %
Explanation:
The percent dissociation of a weak acid can be defined as:
Moles of weak acid that produced H₃O⁺ species / Total number of weak acid moles * 100%
We are given all the required data to calculate the percent dissociation:
0.42 mol / 0.75 mol * 100 % = 56 %
The percent dissociation is 56%.
