Answer:
With distance from the ridge crest, the sediments and crust get thicker. This also supports the idea that the youngest rocks are on the ridge axis and that the rocks get older with distance away from the ridge (Figure below). Something causes the seafloor to be created at the ridge crest.
Answer:
Molar Mass=193.9738 g/mol
Molar Mass≅194g/mol
Explanation:
Consider the formula:
m=ΔT/K_{f}
where:
ΔT is freezing point depression
K_{f} is freezing point depression constant
m is the morality=(moles of solute/kg of solvent)
Now:
Now:
0.07733 (moles of solute/kg of solvent) *0.010 kg of solvent
moles of solute(Caffeine)
Molar mass = Mass of solute/moles of solute
Molar Mass=
Molar Mass=193.9738 g/mol
Molar Mass≅194g/mol
Answer:
The total number of atoms does not change, so mass is conserved in the reaction.

Translational kinetic energy is the kinetic energy of an object of finite size. It is equal to one half the product of the mass of the object and the square of the velocity. For an ideal gas, it is simplified into the expression:
Kinetic energy = 3nRT / 2 where n is the number of moles, R is the universal gas constant and T is the temperature of the gas.
We calculate as follows:
Kinetic energy = 3nRT / 2
Kinetic energy = 3 (0.020 moles ) (8.314 J / mol-K) (290 K) / 2
Kinetic energy = 72.33 J
Therefore, the translational kinetic energy of the ideal nitrogen gas is 72.33 J.
T is in seconds (s)
<span>2pi is dimensionless </span>
<span>L is in meters (m) </span>
<span>g is in meters per second squared (m/s^2) </span>
<span>so you can write the equation for the period of the simple pendulum in its units... </span>
<span>s=sqrt(m/(m/s^2)) </span>
<span>simplify</span>
<span>s=sqrt(m*s^2*1/m) cancelling the m's </span>
<span>s=sqrt(s^2) </span>
<span>s=s </span>
<span>therefore the dimensions on the left side of the equation are equal to the dimensions on the right side of the equation.</span>
