Answer:we can calculate the answer by following steps;
Explanation:
Answer:
10 metres
Explanation:
So, we are given the following data or parameters or information which is going to assist us in solving this particular problem or Question efficiently.
=> The speed of the space ship can be found from this relationship: ✓(1 - [v^2/c^2] ) = 1/2.
=> The length of the space ship = 20 m.
=> Assumption = '' If the length of the ship is measured by the inertial earth-bound observer".
Thus, from the speed of the space ship can be found from this relationship we can determine the value;
✓(1 - [v^2/c^2] ) = 1/2.
V = 20 × 1/2 = 10 metres.
Note that we use the contraction formula to solve for V.

Answer:
![F \approx 3*10^6](https://tex.z-dn.net/?f=F%20%5Capprox%203%2A10%5E6)
Explanation:
From the question we are told that:
Dimension of plate: ![4 m by 8 m](https://tex.z-dn.net/?f=4%20m%20by%208%20m)
Depth submerged ![d=9m](https://tex.z-dn.net/?f=d%3D9m)
Water density ![\rho=1000 kg/m3](https://tex.z-dn.net/?f=%5Crho%3D1000%20kg%2Fm3)
Gravity ![g=9.8m/s^2](https://tex.z-dn.net/?f=g%3D9.8m%2Fs%5E2)
Generally the equation for Volume is mathematically given by
![V=L*B*d](https://tex.z-dn.net/?f=V%3DL%2AB%2Ad)
![V=4*8*9](https://tex.z-dn.net/?f=V%3D4%2A8%2A9)
![V=288](https://tex.z-dn.net/?f=V%3D288)
Therefore The mass of Plate is
![m=\rho*V](https://tex.z-dn.net/?f=m%3D%5Crho%2AV)
![m=1000*288](https://tex.z-dn.net/?f=m%3D1000%2A288)
![m=288000kg](https://tex.z-dn.net/?f=m%3D288000kg)
Generally the equation for Force on the plate is mathematically given by
F=ma
![F=288000*9.8](https://tex.z-dn.net/?f=F%3D288000%2A9.8)
![F=2822400N](https://tex.z-dn.net/?f=F%3D2822400N)
![F=2.8*10^6](https://tex.z-dn.net/?f=F%3D2.8%2A10%5E6)
![F \approx 3*10^6](https://tex.z-dn.net/?f=F%20%5Capprox%203%2A10%5E6)
