Answer:

Answer:

safe speed for the larger radius track u= √2 v

Explanation:

The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.

Also given that r_1= smaller radius

r_2= larger radius curve

r_2= 2r_1..............i

let u be the speed of larger radius curve

now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=

r

1

mv

2

=

r

2

mu

................ii

form i and ii we can write

v^2= \frac{1}{2} u^2v

2

=

2

1

u

2

⇒u= √2 v

therefore, safe speed for the larger radius track u= √2 v

Answer:

1. Comics vs. Story books

Comics relay stories chronologically with artwork and text in speech bubbles, whereas story books relay stories through their written word and little to no illustration. Both are similar in the fact that they are meant to share stories with the reader.

2. Flowchart vs. Essay

A flowchart is a diagram that represents a workflow, process, or idea. Similarly, essays describe the same thing. Though unlike flowcharts it relays this information through organized paragraphs.

3. PowerPoint Presentation vs. Word Format Explanation

Both PowerPoint presentations and word format explanations aim to explain a topic or idea to the reader or watcher. Though the difference between the two is one does so through a visual slide show meant to make the information engaging to the watcher. On the contrary, a word format explanation delivers the information through text that a person must read to understand.

4. Advertisement in pamphlet vs. Advertisement in television.

Advertisement in pamphlets and television are meant to show off the benefits of a product to potential buyers. Both do very similar things, but television advertisements usually last just a few seconds, and show clips of people either discussing the product or happily showing it off. Advertisements shown on pamphlets are arguably much shorter, consisting of a single page with large pictures and typically bolded words that aim to convince potential customers to buy into the product.
