Answer:
This cannot be determined without knowing the actual mass of the objects.

The movement of the blades represents wind energy.
The visible light that allows people to see where they are going describes light energy.
<h3 /><h3>What is a wind energy?</h3>
A wind energy is the energy that results from the blowing the wind.
The blowing of the wind causes the windmill blade to rotate converting kinetic energy into mechanical energy of the moving blades.
<h3>What is light energy?</h3>
Light energy is the energy that allows light to be visible to human eyes.
Thus, we can conclude that the movement of the blades represents wind energy.
The visible light that allows people to see where they are going describes light energy.

Answer: B.) 0.827
Explanation:
Given the following :
Equilibrium constant (k) = 0.75
Forward rate constant = 0.62 mol/L/s
Backward rate constant =?
The equilibrium constant denited as 'k' is the proportion of the forward rate constant and the reverse rate constant.
Mathematically,
K = [forward rate constant / Reverse rate constant]
k = 0.75 ; forward rate constant = 0. 62mol/L/s
0.75 = [ 0.62mol/L/s ÷ reverse rate constant]
Reverse rate constant * 0.75 = 0.62mol/L/s
Reverse rate constant = (0.62mol/L/s ÷ 0.75)
Reverse rate constant = 0.8266mol/L/s
Reverse rate constant = 0.827mol / L/s
Answer:
The right option is the 4 one. nucleoid
Prokaryotic cells are simple cells that lack a definite nucleus and some membrane-bound organelles. Prokaryotic cells have a nucleoid region, which is an irregularly-shaped central region of the cell that contains the cell’s genetic information (DNA). Other organelles that can be found in prokaryotic cells include plasma membrane, cell wall, cytoplasm, and ribosomes.

Answer:
ΔH is negative and ΔS is negative.
Explanation:
Endothermic reaction -
The type of reaction in which energy is absorbed in the form of heat is known as endothermic reaction .
The reaction mixture usually get cooled after the reaction .( temperature decreases ) .
The sign of ΔH of an Endothermic reaction is positive .
<u>For the of process of freezing the liquid ethanol , energy in the form of heat is released and hence , exothermic reaction ΔH is negative .</u>
<u>In the process of freezing , liquid is converted to solid , i.e. , the randomness reduces , and hence , entropy also decreases , hence , ΔS is negative .</u>
