<h3> The skeletal system is your body's central framework. It consists of bones and connective tissue, including cartilage, tendons, and ligaments. It's also called the musculoskeletal system.</h3>
Answer:
1) Force on top face ![=1.09kN](https://tex.z-dn.net/?f=%3D1.09kN)
2)Force on the side face![=1.539kN](https://tex.z-dn.net/?f=%3D1.539kN)
Explanation:
a)
We know that
![Force=Pressure\times Area](https://tex.z-dn.net/?f=Force%3DPressure%5Ctimes%20Area)
Pressure shall be calculated at a depth of (1-0.45) meters from the top of the water surface
![Pressure=\rho \times g\times h\\\\\therefore Pressure=1000\times 9.81\times (1-0.45)Pa\\\\Pressure=5.395kPa](https://tex.z-dn.net/?f=Pressure%3D%5Crho%20%5Ctimes%20g%5Ctimes%20h%5C%5C%5C%5C%5Ctherefore%20Pressure%3D1000%5Ctimes%209.81%5Ctimes%20%281-0.45%29Pa%5C%5C%5C%5CPressure%3D5.395kPa)
Thus force is calculated as under
![Force=5.395\times (0.45)^{2}\\\\Force=1.09kN](https://tex.z-dn.net/?f=Force%3D5.395%5Ctimes%20%280.45%29%5E%7B2%7D%5C%5C%5C%5CForce%3D1.09kN)
b)
The force on one of it's sides is calculated in the same manner except that the pressure is obtained at the centroidal level of the face of cube
Thus
![Force=\rho \times g\times h_{cg}\times Area\\\\Force=1000\times 9.81\times (1-\frac{0.45}{2})\times (0.45)^{2}\\\\Force=1.539kN](https://tex.z-dn.net/?f=Force%3D%5Crho%20%5Ctimes%20g%5Ctimes%20h_%7Bcg%7D%5Ctimes%20Area%5C%5C%5C%5CForce%3D1000%5Ctimes%209.81%5Ctimes%20%281-%5Cfrac%7B0.45%7D%7B2%7D%29%5Ctimes%20%280.45%29%5E%7B2%7D%5C%5C%5C%5CForce%3D1.539kN)
Answer:
<h2>133.33 kg</h2>
Explanation:
The mass of an object can be found by using the formula
![m = \frac{f}{a} \\](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7Bf%7D%7Ba%7D%20%20%5C%5C%20)
f is the force
a is the acceleration
From the question we have
![m = \frac{2000}{15} = \frac{400}{3} \\ = 133.3333](https://tex.z-dn.net/?f=m%20%20%3D%20%5Cfrac%7B2000%7D%7B15%7D%20%3D%20%20%5Cfrac%7B400%7D%7B3%7D%20%20%20%5C%5C%20%20%3D%20133.3333)
We have the final answer as
<h3>133.33 kg</h3>
Hope this helps you
