The cyclist travels at a constant speed of between 3 and 6 seconds. How does the graph show this?

A Cyclist And A Runner Have A Race. The Distance-time Graph For The Race Is Shown Below.The Cyclist Travels

Answers

Answer 1

The distance increased by equal amounts in equal time intervals.

How do you detect constant speed from a distance time graph?

To detect constant speed from a distance-time graph, you need to look for a straight line on the graph. A straight line on a distance-time graph indicates that the object is moving at a constant speed.

If  the slope of the line on the distance-time graph is constant (i.e., the line is straight), then the object is moving at a constant speed. The slope of the line represents the speed of the object.

What is the hundredth ?

The hundredth is a number that stands out among its peers, representing a milestone in any sequence. Its numerical value is 100, and it is made up of two digits, a one and a zero. In mathematics, the hundredth is regarded as a unit fraction, which is the inverse of 100. It is also a multiple of ten, with the number ten being the base of the decimal system. In addition to its numerical value, the hundredth is also a word used to describe something that is of the highest quality or importance. For example, a hundredth anniversary would be a significant event worthy of celebration.

A widow's peak hairline is dominant (W) to a straight hairline (w). Karen and her brother both have a straight hairline, but her parents and sister all have a widow's peak. Complete the Punnett square that shows Karen's family

Answers

Answer:

Karen and her brother both have a genotype 'ww' (phenotype straight hairline), whereas the father and sister have a genotype 'Ww' (phenotype peak hairline).

Explanation:

A Punnett square is a representation of how different gametes combine to produce distinct genotypes from a given genetic cross.

A Punnett square is very useful to decipher the possible expected genotypes and phenotypes of a given genetic cross.

In this case, the father will be heterozygous 'Ww', thereby producing two types of gametes: W and w, whereas the mother will be homo-zygous 'ww', producing only one type of gamete: w.

The Punnett square here is:

                 W         w

         w     Ww      ww

         w     Ww      ww

In conclusion, Karen and her brother both have a genotype 'ww' (phenotype straight hairline), whereas the father and sister have a genotype 'Ww' (phenotype peak hairline

A widow's peak hairline is dominant (W) to a straight hairline (w). Karen and her brother both have a straight hairline, but her parents and sister all have a widow's peak. To complete the Punnett square that shows Karen's family, we need to determine the genotypes of her parents and then use that information to create the Punnett square.

Since a widow's peak is dominant, we know that Karen's parents must both have at least one W allele. However, since Karen and her brother both have straight hairlines, we also know that they must have at least one w allele. Therefore, the genotypes of Karen's parents must be Ww and Ww.

Using this information, we can create the Punnett square:


 
   
   W
   w
 
 
   W
   WW
   Ww
 
 
   w
   Ww
   ww
 

From this Punnett square, we can see that there is a 25% chance of a child having a straight hairline (ww) and a 75% chance of a child having a widow's peak (WW or Ww). This explains why Karen and her brother both have straight hairlines, while her parents and sister all have widow's peaks.

A cyclist and a runner have a race. The distance-time graph for the race is shown below

i) When the race started, a walker set off at a steady speed of 2m/s. Draw a line on the graph

to show the distance the walker covers in the first 15 seconds. Use a ruler.


ii) Calculate how many seconds it will take for the walker to walk 100m

Answers

According to the data, the line showing the relationship between time and distance of the walker is the purple line on the graph.

How to graph the distance traveled by the walker?

A graph can be defined as an instance in which the data and the numerical value will be presented in a graphic form. This will be based on the numerical values. This can include lines, dots, and bars to represent the data.

In order to graph the distance that the walker travels over time we must take into account the speed at which he walks. In this case it maintains a constant speed of 2m/s. This means that the coordinates in the plane of this displacement are:

(0, 0)

(1, 2)

(2, 4)

(3, 6)

(4, 8)

(5, 10)

(6, 12)

(7, 14)

(8, 16)

(9, 18)

(10, 20)

(11, 22)

(12, 24)

(13, 26)

(14, 28)

(15, 30)

According to the above, the coordinate information matches the track information and the end point of this displacement would be (15, 30).
