Max (mass = 15 kg) is hanging from one end of a 13-m long bungee cord that has its other end fixed to a bridge above. The bungee

Rashid [163]

The stress experimented by the bungee cord due to Max's weight is approximately 299.680 kilopascals.

<h3>How to find the stress experimented by the bungee cord</h3>

Let suppose that the stress ( $\sigma$ ), in pascals, experimented by the bungee cord is entirely <em>elastic </em>and <em>uniform</em>. By Newton's Laws we know that the tension ( $T$ ), in newtons, experimented by the cord equals Max's weight. The stress on the bungee cord is axial and is described by following formula:

$\sigma = \frac{m\cdot g}{\frac{\pi\cdot D^{2}}{4} }$ (1)

Where:

$m$ - Max's mass, in kilograms
$g$ - Gravitational acceleration, in meters per square second
$D$ - Diameter of the circular cross section, in meters

If we know that $m = 15\,kg$ , $g = 9.807\,\frac{m}{s^{2}}$ and $D = 0.025\,m$ , then the stress experimented by the bungee cord is:

$\sigma = \frac{(15\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}{\frac{\pi}{4}\cdot (0.025\,m)^{2} }$

$\sigma \approx 299679.845\,Pa\, (299.680\,kPa)$

The stress experimented by the bungee cord due to Max's weight is approximately 299.680 kilopascals. $\blacksquare$

There are 12 of the zodiac. how many people are needed to guarantee that at least six of these people have the same sign? your a

ElenaW [278]

Answer:es, the answer is 61. This is related to a mathematical principle called the Pigeonhole Principle, which states that if you are trying to sort n+1 objects into k sets (where nk=r;n,k,r∈Z+), at least one set must contain at least r+1 objects. (This can be proven by proof by contradiction, but is pretty standard and so generally can just be used as justification of an answer by itself.)

For your problem, you have 12 signs of the zodiac - these are your 12 sets (so k=12). You are looking to find how many it takes before a set contains 6 objects (so r+1=6 and thus r=5). Therefore, n+1=r×k+1=12×5+1=61.

A system that keeps track of each withdrawal or addition to inventory continuously is

stealth61 [152]

A perpetual inventory system is one that continuously tracks each withdrawal or addition to inventory. Perpetual inventory is a continuous accounting practise that records inventory changes in real time, eliminating the need for physical inventory, so that the book inventory accurately reflects the actual stock.

This system starts with a physical count as a baseline and updates based on purchases made in and shipments made out.

The perpetual system may be better suited for businesses with larger, more complex inventory levels and higher sales volumes. Grocery stores and pharmacies, for example, typically use perpetual inventory systems.
