<span>Answer: 0.00 meters
Solution:
Step 1: Define displacement
DISPLACEMENT = a vector quantity that describes "linear or angular distance in a given direction between a body or point and a reference position."
Step 2: Understand the question
Assumption 1: Assume that when the ant moves 4.25 meters from its origin to its nest, it is moving in a positive direction (on a graph you would draw a line along the x-axis from its origin to +4.25).
Assumption 2: Assume that when the ant "turns around...back to the source of food", it is moving back in the negative direction (towards the origin).
Step 3: Analyze the question
What is the distance between where the ant originally started and where it ended its journey?
The ant started and ended its journey in the same place.
While it traveled a distance of 8.52 meters (2 * 4.26 = 8.52), it's displacement is actually 0.00 meters (4.26 + (-4.26) = 0.00)
Therefore, the answer is 0.00 meters</span>
Answer: Option (b) is the correct answer.
Explanation:
According to ideal gas law, the product of pressure and volume is equal to the product of number of moles, gas constant and temperature.
Mathematically, PV = nRT
So, when there are two gases with equal number of moles behaving ideally then the ideal gas equation will be as follows.
=
and =
Hence, when temperature and pressure of both the gases will be constant then = 1.
Thus, we can conclude that constant temperature and pressure is the conditions that must be met for a volume ratio to be created from a balanced chemical equation.
Answer:
The creation of regulations that limit timber activities and the exploitation of wood can prevent soil erosion in Troy.
Explanation:
The exploitation of the wood was an intense activity and that did not have any regulation that would limit its damages, caused by its exploratory activities.
As the timber market was totally undisciplined, the exploitation of the wood caused a strong deforestation, leaving the soil totally unprotected and susceptible to strong erosion.
Soil erosion has a very negative impact on the environment, requiring regulations to be made to prevent this from happening.
Based on this, we can say that one way to prevent environmental problems in the seaport of troy is by establishing laws and regulations that limit logging activities.
Answer:
The Emf of the given cell at [Fe2+] = 2.0 M and [Fe3+] = 1.9 M is 0.48 V
Explanation:
The half cell reaction can be written as :
Anode-Half (oxidation) :
......E = 0.77 V
(multiply this equation by 4 to balance the electrons)
Cathode-half (reduction)
....E= 1.23 V
According to Nernst Equation
n = number of electron transferred in the cell reaction = 4
The balanced equation is :
Insert the value of log Q in Nernst Equation:
(using :
)
Answer: Thus the value of the equilibrium constant is
Explanation:
Equilibrium constant is the ratio of the concentration of products to the concentration of reactants each term raised to its stochiometric coefficients.
At eqm. conc. (0.20) M (0.25) M (1.20) M
The expression for equilibrium constant for this reaction will be,
The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
Thus the value of the equilibrium constant is
