Why does a curve on a distance-time graph indicate acceleration?

Biology
1 answer:
fgiga [73]3 years ago
4 0

A curve on a distance-time graph indicates distance with respect to time.

For someone good in interpreting curves, the slope of distance/time at each point on the curve represents the velocity.

For someone still better in reading curves, the second derivative of the curve at any point indicates acceleration. Second derivative means the rate of variation of velocity with respect to time.

So the quick answer is a curve on a distance time graph does NOT directly indicate acceleration. See example in attached diagram. If you can "see" the constant acceleration indicated in the bottom (distance-time) graph, then yes, you can find acceleration from a distance-time graph. Otherwise, the answer is still no.

Why would it be wise for a woman carrying the hemophilia gene to keep her son from being circumcised?
xenn [34]

Answer:

Because the probability of hemophilia would be 1:4

Explanation:

Hemophilia is a disease that comes with a sex chromosome (pair 46).

It is a recessive allele associated with chromosome X, women have two X chromosomes they can carry it, but they don't have it because they have another dominand allele non-hemophilic.

If you draw a Punnet square with a non-hemophilic father and a carrying mother, you'll found you have 1:4 chances of having a baby boy with hemophilia.

Carrying mother = X(H)X(h)

Father = X(H) Y

It is a season in which fish reproduce.

Piracema is not name of the fish, its the name given to the period of the year when fish reproduce within the Paraguay River. The season of reproduction started from October till March, during this period the fish swim upstream to lay their eggs and reproduce. Thus the season is critical for the maintenance of fish populations in the waters of the rivers and lakes. Brazilian states prohibit fishing during this period in order to maintain fish population in the river.
