1pt Which of the following is NOT true about the role tectonic forces play in the rock cycle?
O A. When plates pull apart, rocks melt, and magma forms igneous rocks.
O B. When plates crash together, rocks are buried and form metamorphic rocks.
O c. When plates slide over and under each other, the heat and pressure form igneous rocks.
OD. When rocks push upward and form mountains, the erosion of the mountains can produce sediment.
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.

Why is nuclear energy considered a nonrenewable resource?
Nuclear radiation does not run out.
It comes from radiation from the sun.
Uranium ore is replaced on a geologic timescale.
Uranium replenishes more quickly than it is being used.
Answer:
You could classify nuclear energy as nonrenewable because uranium and similar fuel sources are finite. On the other hand, some people consider nuclear energy renewable because the element thorium and other new technologies may provide infinite fuel needed to power nuclear reactors.

mole-mass problem:
Water decomposes to produce hydrogen gas and oxygen gas. How many moles of oxygen would be produced from 10.0 moles
water? 2 H2O → 2 H2 + O2
Answer:
5.00 mol O₂
Explanation:
2H₂O → 2H₂ + O₂In order to solve this problem we will need to convert moles of water to moles of oxygen. We will do that using the stoichiometric coefficients, as follows:
10.0 mol H₂O * [tex]\frac{1molO_2}{2molH_2O}[/tex] = 5.00 mol O₂Thus 5.00 moles of oxygen would be produced from 10.0 moles of water.

If the spring constant is 12.6N/m and a spring is stretched by 0.25m, how much force has been applied?
Answer:
The magnitude of the applied force is 3.15 N
Explanation:
Hooke's law states that for small deformations, the change in dimensions, 'x', of an object is directly proportional to the force, 'F', of the acting load acting that bring about the deformation
Mathematically, Hooke's Law can be expressed as follows;
F = k·x
Where;
F = The applied load
k = The force constant of the object
x = The amount of deformation of the object
The given parameters are;
The spring's force constant, k = 12.6 N/m
The amount of stretching in the spring, x = 0.25 m
Therefore, we have;
The force applied, F = k·x = 12.6 N/m × 0.25 m = 3.15 N.
The pressure and temperature of N² and gas drops from 303kPa at 300K to 202²kPa at -73°C. If the initial volume is 2L, find the new volume.
Answer:
Gjvb
Explanation:
Using the combined gas law equation as follows:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (kPa)
P2 = final pressure (kPa)
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to this question;
T1 = 300K
T2 = -73 + 273 = 200K
P1 = 303kPa
P2 = 202kPa
V1 = 2L
V2 = ?
Using the above formula:
303 × 2/300 = 202 × V2/200
606/300 = 202V2/200
Cross multiply;
606 × 200 = 300 × 202V2
121200 = 60600V2
V2 = 121200/60600
V2 = 2L
The new volume is 2L

A student has a 6 gram sample of sodium chloride (NaCl) solid. How many moles of sodium chloride are contained in this sample?
The number of moles of NaCl = 0.103
Further explanationGiven
6 gram sample of NaCl
Required
moles
Solution
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
mole = mass : molar mass
Molar mass of NaCl = 58.5 g/mol
Input the value :
mole = 6 g : 58.5 g/mol
mole = 0.103
