A child riding a bicycle at 15 m/s accelerates at 3. 0 m/s/s for 4. 0 s. What is the child's speed at the end of this 4. 0 s interval?.

Answers

Answer 1

Answer:

The final speed of bicycle would be 27 m/s².

Step-by-step explanation:

Given :

[tex]\small\red\bull[/tex] Initial velocity (u) = 15 m/s[tex]\small\red\bull[/tex] Acceleration (a) = 3.0 m/s²[tex]\small\red\bull[/tex] Time = 4 seconds

To Find :

[tex]\small\red\bull[/tex] Final velocity (v)

Using Formula :

[tex]\longrightarrow{\pmb{\sf{v = u + at}}}[/tex]

[tex]\small\blue\star[/tex] v = final velocity [tex]\small\blue\star[/tex] u = initial velocity [tex]\small\blue\star[/tex] a = acceleration [tex]\small\blue\star[/tex] t = time taken

Solution :

Substituting the values in the formula to find the final velocity :

[tex]\longrightarrow{\sf{v = u + at}}[/tex]

[tex]\longrightarrow{\sf{v = 15 + (3.0 \times 4)}}[/tex]

[tex]\longrightarrow{\sf{v = 15 + (3 \times 4)}}[/tex]

[tex]\longrightarrow{\sf{v = 15 +(12)}}[/tex]

[tex]\longrightarrow{\sf{v = 15 +12}}[/tex]

[tex]\longrightarrow{\sf{v = 27 \: {m/s}^{2}}}[/tex]

[tex]\star{\underline{\boxed{\red{\sf{v = 27 \: {m/s}^{2}}}}}}[/tex]

Hence, the final speed of bicycle would be 27 m/s².

Marian traveled at an average speed of 65 mi/h for 15 hours. Kristen travels at an average speed of 50 mi/h. How many hours does it take kristen to travel the same distance marian traveled? express your answer as a decimal to the nearest tenth.

Answers

The hours it takes Kristen to travel the same distance Marian travelled is 19.5 hours.

The average speed of Marian is 65 miles per hour for 15 hours. Therefore, her distance travelled can be calculated as follows:

speed = distance / time

Therefore,

distance = time × speed

distance = 15 × 65

distance = 975 miles

Kristen travelled at an average speed of 50 miles per hour. Kristen covers the same distance with Marian. Therefore, the hours it takes Kristen to travel the same distance Marian travelled can be calculated as follows:

speed = distance / time

time = distance / speed

time = 975 / 50

time = 19.5 hours

To compare the average amount of time that canadians and americans spend commuting, a researcher collects a sample of canadians and americans. The canadians spend an average of hours a week commuting, with a standard deviation hours. The mean and standard deviation for the sample of americans is hours and hours, respectively. The standard error of the difference of sample means is:.

Answers

The standard error of the difference of sample means is 0.444

From the complete question, we have the following parameters

Canadians

Sample size = 50Mean = 4.6Standard deviation = 2.9

Americans

Sample size = 60Mean = 5.2Standard deviation = 1.3

The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.

This is represented as:

[tex]SE = \frac{\sigma}{\sqrt n}[/tex]

The standard error of the Canadian sample is:

[tex]SE_1 = \frac{2.9}{\sqrt{50}}[/tex]

So, we have:

[tex]SE_1 = 0.41[/tex]

The standard error of the American sample is:

[tex]SE_2 = \frac{1.3}{\sqrt{60}}[/tex]

So, we have:

[tex]SE_2 = 0.17[/tex]

The standard error of the difference of sample means is then calculated as:

[tex]SE= \sqrt{SE_1^2 + SE_2^2}[/tex]

This gives

[tex]SE= \sqrt{0.41^2 + 0.17^2}[/tex]

[tex]SE= \sqrt{0.197}[/tex]

Take square roots

[tex]SE= 0.444[/tex]

Hence, the standard error of the difference of sample means is 0.444

In general, an organism will be more likely to develop phobias of __________.

Answers

In general, an organism will be more likely to develop phobias of dangers faced during natural circumstances.  

Phobia is an unjustified or pathological fear of situations or circumstances that are not dangerous and that most people do not find bothersome.  Fear is a natural reaction or an adaptive experience to situations or objects that imply a real danger.

When this fear occurs before natural circumstances that do not pose a real danger, then we find this fear is no longer adaptive is what we call a phobia.

Therefore, we can conclude that an organism will be more likely to develop phobias of dangers faced during natural circumstances.

Consider a system of two objects and earth. Object x and object y are held together by a light string as shown in the figure. My is larger than mx. The two-object system is released from rest in the orientation shown in the figure at a height h above earth’s surface. The change in the kinetic energy of the system from when it is released to the instant it hits the ground is most nearly.

Answers

The change in the kinetic energy of the system from when it is released to the instant it hits the ground is most nearly;  (My + Mx)gH

We are told that the two objects X and Y are held together by a light string.

Their masses are;

Mass of Object X = Mx

Mass of objetc Y = My

Since the two objects are released from rest, it means we need to find potential energy and the formula for potential energy is;

P.E = mgh

Now, since both objects are released from rest and since My is larger than Mx, it means that potential energy is now;

ΔP.E = (My + Mx)gH

Now, according to conservation of energy,

Change in kinetic energy = Change in potential energy.

Thus;

Change in kinetic energy = (My + Mx)gH

Which statement best explains a difference between a character vs. Self conflict and a character vs. Character conflict?.

Answers

Answer: A character vs. Self conflict and a character vs. Character conflict are two different types of conflicts commonly found in literature. Here's an explanation of the difference between the two:

Character vs. Self Conflict:

Character vs. Self conflict, also known as internal conflict, occurs when a character struggles with their own thoughts, emotions, beliefs, or decisions. It is a psychological or emotional struggle within the character's mind. The conflict arises from a moral dilemma, self-doubt, guilt, fear, or any internal obstacle that the character must overcome.

Example: A protagonist who is torn between following their principles and doing what is morally right, even if it puts them in danger or conflicts with their personal desires, is experiencing a character vs. Self conflict.

Character vs. Character Conflict:

Character vs. Character conflict, also known as external conflict, involves a struggle between a character and an external force, typically another character. This type of conflict arises from opposing goals, interests, or ideologies between two or more characters. The conflict is usually more overt and may involve verbal or physical confrontations.

Example: In a story, the hero and the villain engage in a battle of wits and physical confrontation. This conflict is an example of character vs. Character conflict.

In summary, the key difference lies in the source of the conflict. Character vs. Self conflict is internal, involving the character's own thoughts and emotions, while character vs. Character conflict is external, involving clashes between different characters and their opposing objectives or viewpoints. Both types of conflict play essential roles in developing the plot and character arcs in a story.
