A manufacturer makes two types of drinking straws: one with a square cross-sectional shape, and the other type the typical round

Harlamova29_29 [7]

Answer:

$\frac{Q_{square}}{Q_{circle}} = 0.785$

Explanation:

given data

types of drinking straws

square cross-sectional shape
round shape

solution

we know that both perimeter of the cross section are equal

so we can say that

perimeter of square = perimeter of circle

4 × S = π × D

here S is length and D is diameter

S = $\frac{\pi D}{4}$ ....................1

and

ratio of flow rate through the square and circle is here

$\frac{Q_{square}}{Q_{circle}} = \frac{AV^2}{AV^2}$

$\frac{Q_{square}}{Q_{circle}} = \frac{S^2}{\frac{\pi D^2}{4}}$

$\frac{Q_{square}}{Q_{circle}} = \frac{(\frac{\pi D}{4})^2}{\frac{\pi D^2}{4}}$

$\frac{Q_{square}}{Q_{circle}} = \frac{\pi }{4}$

$\frac{Q_{square}}{Q_{circle}} = 0.785$

Maintain a distance of at least _____ between your vehicle and the vehicle behind you

Serga [27]

A

Maintain a distance of at least __2___ between your vehicle and the vehicle behind you.

Explanation:

As the car infront passes a stationary object like a lamp post, the driver in the car behind should count at least two- seconds before their car reached and passes the stationary object too. This two-second rule ensures that cars maintain a safe distance between each other to avoid tailgaiting and collisions.

This rule leaves at least some room for the drivers to react swiftly enough, and avoid collisions, in case the car infront holds emergency breaks. It is even recommended that more seconds are used in hazardous conditions such as fog and slippery roads.
