41.0 + 78.3 =
Answers
Ans: 1) 1.41
2) 119.3
While adding two numbers, the rule of significant figures requires that the number of decimal places in the final answer is equal to that of the term with the least decimal places
In the given examples:
1) 0.09 - has 2 decimal places
1.324- has 3 decimal places
Sum = 0.09 + 1.324 = 1.414
Round off to 2 decimal places = 1.41
2) 41.0 - has 1 decimal place
78.3- has 1 decimal place
Sum = 41.0 + 78.3 = 119.3
Final answer will also have 1 decimal place = 119.3
1. 1.141
2. 119.3

O As potential energy increases, kinetic energy decreases.
As potential energy decreases, kinetic energy decreases.
O Potential and kinetic energy are two separate things and have no relationship.
Answers
Answer:
As potential energy increases, kinetic energy decreases
It's an inverse relationship
Final answer:
Potential energy and kinetic energy are related through the law of conservation of energy. When potential energy increases, kinetic energy decreases, and vice versa, as energy is simply converted between these two forms.
Explanation:
The relationship between kinetic energy and potential energy lies within the law of conservation of energy. This law states that energy cannot be created or destroyed, only converted from one form to another.
Potential energy is the energy stored in an object due to its position in a force field or due to its configuration. For example, when you lift a book off the ground, it gains potential energy because of the work done against the force of gravity.
On the other hand, kinetic energy is the energy of an object due to its motion. The same book, when dropped, loses potential energy and gains kinetic energy as it falls towards the ground.
Hence, when potential energy increases, kinetic energy decreases, and vice versa. This is because the total energy (potential + kinetic) must be conserved, assuming no energy is lost to other forms like heat or sound.

Answer: correct option is the option B= 2.6 × 10^-5 mol.sec^-1
Explanation:
Check attached file/picture for the plot of graph of reaction velocity against substrate concentration.
Initial velocity can be defined as the velocity at the beginning of an enzyme-catalyzed reaction. It is usually denoted as V°.
In the equation of reaction below;
A + B----------> [AB] ------------>Product
<--------
Where the forward reaction is k1 that is the rection producing the intermediate [AB].
And, the backward reaction is k-1 that is the arrow pointing back to the Reactants.
K2 is the arrow from the intermediate [AB] to the products.
Note that k1 and k-1
represent rapid non-covalent dissociation of substrate from enzyme active site. Also, K2 is the rate constant for the formation of the products.
In order to calculate the initial velocity,V° we need to use the Michaelis- Menteen equation.
V° = Vmax ×(S)/ Km + (S)-------------------------------------------------------------(1).
From the question the parameters given are;
Vmax = 6.5 x 10–5 mol•sec–1 , [S] = 3.0 x 10–3 M, and KM = 4.5 x 10–3 M.
Therefore, slotting in the above parameters into the equation (1) above, we have;
V° = 6.5 x 10–5 mol•sec–1 × 3.0 x 10–3 M / 4.5 x 10–3 M + 3.0 x 10–3 M.
Initial velocity,V° = 2.6 x 10-5 moles per sec..

Answer:
Because as the concentration is diminished, the capacity to transfer electricity is diminished as well.
Explanation:
Hello!
In this case, since electrolytes are substances that are able to conduct the electricity in aqueous media (solutions in which water is the the solvent) because they have the capacity to form ions with both positive and negative charges, due to the fact that HCl is a strong acid, we notice it is fully ionized in solution and therefore it is a strong electrolyte. However, when the concentration is diminished, we can notice that strength is diminished as well because less ions will have the capacity to transfer the electricity and therefore it'd become a poor conductor or weak electrolyte.
Best regards!

Answer: The final temperature of the sample is 62.66°C
Explanation:
To calculate the amount of heat absorbed, we use the equation:
where,
Q = heat absorbed = 16.7 kJ = 16700 J (Conversion factor: 1 kJ = 1000 J)
m = Mass of the sample = 225 g
c = specific heat capacity of sample =
= change in temperature =
Putting values in above equation, we get:
Hence, the final temperature of the sample is 62.66°C

1. Based on the experiment in the scenario, which visual aid would be most helpful in showing the change in the plants' heights over time?
O A. A line graph
O B. A pie chart
OC. A bar graph
O D. A timeline
Answers
Answer:
A. A line graph
Explanation:
You use line graphs to track changes over time. Line graphs are better when the changes are small. They are also more useful when you want to compare changes over the same period for more than one group, for example, plants exposed to music and a control group.
B is wrong. A pie chart is best for comparing parts of a whole.
C is wrong. You can use a bar graph to track changes over time, but small changes are harder to spot.
D is wrong. You use a timeline to mark important points in time, for example, when you are deciding the times when you must complete various stages of a project.
Which of the charts below do you think is more helpful in showing the change in plant height over time?
