<span>The intensity of an earthquake is dependent on one's proximity to the focus of the quake, also called the "epicenter" and is based on observations of the shaking of the ground on humans, structures, and the natural landscape.</span>
Answer:
4.96 × 10⁵ Pa
Explanation:
F = mg
![F = (m_{person}+m_{stool})g\\\\F = (4.5 + 89)*9.8\\\\F = 916.3 N](https://tex.z-dn.net/?f=F%20%3D%20%28m_%7Bperson%7D%2Bm_%7Bstool%7D%29g%5C%5C%5C%5CF%20%3D%20%20%284.5%20%2B%2089%29%2A9.8%5C%5C%5C%5CF%20%3D%20916.3%20N)
This force is evenly distributed on the three leg
radius, r = d/2
= 2.8 / 2
= 1.4 cm = 0.014 m
total cross sectional area of the three legs, A = 3*pi*r^2
![= 3\times\pi \times0.014^2\\\\= 1.847\times10^-^3m^2](https://tex.z-dn.net/?f=%3D%203%5Ctimes%5Cpi%20%5Ctimes0.014%5E2%5C%5C%5C%5C%3D%201.847%5Ctimes10%5E-%5E3m%5E2)
Pressure due to weight,
P = Weight/A
![P = / 1.847 × 10⁻³\\P = \frac{ 916.3N}{1.847\times10^-^3} \\\\P= 496032.9Pa](https://tex.z-dn.net/?f=P%20%3D%20%2F%201.847%20%C3%97%2010%E2%81%BB%C2%B3%5C%5CP%20%3D%20%5Cfrac%7B%20916.3N%7D%7B1.847%5Ctimes10%5E-%5E3%7D%20%5C%5C%5C%5CP%3D%20496032.9Pa)
P = 4.96 × 10⁵ Pa
Answer:
1.28
Explanation:
If you want to find the m/s you would divide distance by time, so
45 divided by 35 would equal 1.28571429 and so on.
you can just write the three first numbers.
