Tectonic forces do not cause plates to slide over and under each other, to produce heat and pressure which forms igneous rocks
What is the rock cycle?The rock cycle is a cycle which describes how the three basic rock types are related and how earth processes convert one rock type into another over geologic time.
Plate tectonic forces together with weathering and erosional processes, are responsible for the rock cycle.
Tectonic forces play the following roles in rock cycle:
When plates pull apart, rocks melt, and magma forms igneous rocks.When plates crash together, rocks are buried and form metamorphic rocksWhen rocks push upward and form mountains, the erosion of the mountains can produce sedimentTherefore, the statement that when plates slide over and under each other, the heat and pressure form igneous rocks is not True.

travels through brass, air, and glass. What is the wavelength of the wave in
brass?
Medium
Wave speed
(m/s)
Brass
4,700
Air
346
Glass

A. 0.64 m
B. 1.6 m
C. 0.064 m
D. 16 m
The wavelength of the wave in brass medium, given that the wave has a frequency of 300 Hz is 16 m (Option D)
How do I determine the wavelength in brass?The wavelength of a wave is defined according to the following formula:
Velocity (v) = wavelength (λ) × frequency (f)
Divide both sides by frequency
Wavelength (λ = Velocity (v) / frequency (f)
With the above formula, we can obtain the wavelength of the wave in the brass medium. Details below:
Frequency (f) = 300 HzWave speed in brass (v) of = 4700 m/sWavelength in brass (λ) = ?Wavelength (λ = Velocity (v) / frequency (f)
Wavelength in brass = 4700 m/s / 300 Hz
Wavelength in brass= 16 m
Thus, we can conclude that the wavelength is 16 m (Option D)

Calculate the vapor pressure (in torr) of a 35°C solution of ethanol and propanol where the mole fraction of propanol is .75. Assume Ideal behavior P°ethanol35=100torr P°propanol35=36torr
The vapor pressure (in torr) of a 35°C solution : 52 torr
Further explanationGiven
x propanol = 0.75
P°ethanol=100 torr
P°propanol=36 torr
Required
the vapor pressure
Solution
Raoult's Law
P solution = xA.P°A +xB.P°B
x ethanol = 1- 0.75 = 0.25
Input the value :
P solution = 0.25 x 100 + 0.75 x 36
P solution = 25 + 27
P solution = 52 torr
What word is the biotic factor in this sentence:
Fish breath oxygen that is dissolved in water.
Answer: Fish
Explanation:
Biotic factor is one of the component of the ecosystem. It is the living component of the ecosystem. It is affected or influenced by the non-living or abiotic components of the ecosystem like water, air, sunlight, and others. Fish is an example of biotic factor which is dependent on abiotic component that is oxygen which is the chief gas required for the breathing. The oxygen is one of the components of the water. So, the oxygen is dissolved in water and the fish acquire the oxygen through water only.

Jacob walked into a shop to buy cups for his house. He saw the cups shown below. Why does the cup on the right appear yellow? A. The cup absorbs yellow light but reflects all other colors of light. B. The cup reflects yellow light but refracts all other colors of light. C. The cup refracts yellow light but absorbs all other colors of light. D. The cup reflects yellow light but absorbs all other colors of light.
Answer:
D. The cup reflects yellow light but absorbs all other colors of light.
Explanation:
The cup in the shop appears yellow because the cup reflects yellow light but absorbs all colors of light.
Due to the materials the cup is made of, it is able to specifically reflect yellow and absorb other radiation types.
The color we see are products of the part of visible radiations they reflect.
The cup in this instance reflects yellow and absorbs other color.

1. Ammonia gas occupies a volume of 450. ml at a pressure of 720, mm Hg. What
volume will it occupy at standard pressure?
Answer:
720+450 = 1170 it's 1170
426.32mL (rounded)
The formula for finding V2 is P1 • V1/P2 and since standard pressure (1atm) is equal to 760 P2 would be 760.
720mmHg • (450mL/760mmHg) = 426.32mL

This is the type of wave that travels in one direction but the energy travels in the opposite direction
Answer:
Transverse wave
Explanation:
A wave is defined as a disturbance along a medium which transfers energy from one point to another.
A wave may be classified as transverse or longitudinal based on the direction of energy transfer relative to the direction of wave motion.
In a transverse wave, energy is transferred in a direction perpendicular to the direction of wave travel. Hence, the direction in which the energy travels is opposite to the direction in which the wave travels.

How many molecules are in 10 moles of H2
The number of molecules in one mole of hydrogen gas is 6.02 × 10²³ . The number of molecules in 10 moles of hydrogen gas is then 6.022 ×10²⁴.
What is one mole?Any substance that contains 6.022 × 10²³ number of atoms is called ne mole of that substance. This number is called Avogadro number. Hence, one mole of every elements contains Avogadro number of atoms.
Hydrogen is the first element in periodic table. It is an alkali metal. The number of molecules in one mole of H₂ is equal to Avogadro number. Mass of a molecule with one mole of amount is called its molecular mass.
Number of molecules of H₂ in one mole = 6.02 × 10²³
Then number of molecules in 10 moles is Avogadro number times the number of moles.
= 10 × 6.022 × 10²³ = 6.022 ×10²⁴ molecules
Therefore, 10 moles of H₂ contains 6.022 ×10²⁴molecules..

When chlorine is added to sodium bromide solution, the mixture turns brown. What type of reaction has taken place?
Answer:
A displacement reaction
Explanation:
This is because the chlorine reacts with the sodium bromide, forcing it to go brown.
I hope this helps, good luck! (✿◡‿◡)
When chlorine is added to a solution of sodium bromide (either as a gas or dissolved in water), the bromine is replaced by the chlorine.
What do you mean by Solution?In chemistry, a solution is a homogeneous mixture of two or more compounds in their relative proportions that can be continually altered up to what is referred to as the limit of solubility.
Although the word "solution" is typically used to refer to the liquid state of matter, solutions of gases and solids are also possible.
When chlorine is added to a solution of sodium bromide (either as a gas or dissolved in water), the bromine is replaced by the chlorine. Because chlorine is more reactive than bromine, sodium bromide loses its bromine content. The mixture darkens to brown. The bromine has been displace, giving this colour of brown.

What is an ecosystem?An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
