8 protons because a element always has the same number of protons as its atomic number
The intermediate disturbance hypothesis predicts that species diversity will be highest when the frequency and/or intensity of disturbances are intermediate
Explanation:
The diversity of the species is maximised at an intermediate near of anthropogenic as well as natural disturbances. As the competitively inferior disturbances are being tolerated for species disturbance and are termed to be dominant. Co exist of the sensitive species when the disturbance are either frequent or rare, which possess the reduced level of the disturbances. the productivity is predicted as very less due to competitive exclusion. As the disturbances increases productivity becomes less as most of them unable to sustain the regular destructive occurrence. So with the intermediate disturbances productivity is high as the rapid colonizers and dominant competitors are able to coexist.
Answer:
0.12KWH
Explanation:
Time: 2hrs
Power: 60watt
60/1000
Formula: Energy=potential/time
0.06×2= 0.12KWH
Complete question: The chart shows the movement of a ball after several seconds.
Column A is on the x-axis, and Column B is on the y-axis. Which titles should replace A and B?
a. Column A should be “Time,” and Column B should be “Position.”
b. Column A should be “Position,” and Column B should be “Time.”
c. Column A should be “Velocity,” and Column B should be “Speed.”
d. Column A should be “Speed,” and Column B should be “Velocity.”
Answer:
Column A should be "Time," and Column B should be "Position"
Explanation:
In general, the first column always refers to the x-axis, this is the independent variables. While the second column refers to the y-axis, the dependent variables.
Option A) names Time and Position to the columns. This seems to be correct as time is an independent variable, while the ball position depends on time. The x-axes is named "time", and the Y-axes is named "ball position".
Option B) is not possible because the Position is not the independent variable, and time is not the dependent variable.
Option C) and D) are not possible, as both of them are variables that depend on time.
Answer:The ratio of the concentrations of and when the buffer has a pH of 7.02 is 0.69
Explanation:
The dissociation constant for formic acid =
Concentration of HA= 0.5 mM
Concentration of = 0.1 mM
pH = 6.16
First we have to calculate the value of .
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
To calculate the ratio of the concentrations of and when the buffer has a pH of 7.02.
Using Henderson Hesselbach equation :
Thus the ratio of the concentrations of and when the buffer has a pH of 7.02 is 0.69
