Sam and Jenny ride their bikes at a constant velocity of 3 miles per hour.
Explanation:
Here we see that both of them are moving at a constant velocity which means their speed is constant and they are moving in a straight line.
Zero acceleration is implied on the bikes and the net force is BALANCED.
When forces are in balance, acceleration is zero. Velocity is constant and there is no net or unbalanced force.
The answer for this question would be letter A. Experimentation takes in by experimenting with your hypothesis, knowing what will happen and then gathering data from the outcome of the experiment. For your data, you create your analysis of what had happened then conclude.
The burden of diseases A and B in country Z is that disease B has a higher prevalence than
disease A. That is option D.
<h3>Health statistics of Country Z</h3>
Health statistics is used by professionals to summarize the health status or information on the health of individuals in a particular geographical location.
The basic statistic tools that can be used to check the health status of a population are,
The prevalence rate is the total number of cases of a disease existing in a population divided by the total population.
The prevalence rate of disease A = 225 per 100,000 population while the prevalence rate of disease B = 500 per 100,000 population.
Therefore, the burden of diseases A and B in country Z is that Disease B has a higher prevalence than
disease A.
