Answer:
0.029%
Explanation:
Weight on the surface is given by,
![F_W = mg = (96.1Kg)(9.8m/s^2)=941.78N](https://tex.z-dn.net/?f=F_W%20%3D%20mg%20%3D%20%2896.1Kg%29%289.8m%2Fs%5E2%29%3D941.78N)
The acceleration due to gravity at given height is,
![g_h=\frac{gR^2}{R+h^2}](https://tex.z-dn.net/?f=g_h%3D%5Cfrac%7BgR%5E2%7D%7BR%2Bh%5E2%7D)
The weight in another height is equal to
![F_h=mg_h](https://tex.z-dn.net/?f=F_h%3Dmg_h)
![F_h= m*\frac{gR^2}{R+h^2}](https://tex.z-dn.net/?f=F_h%3D%20m%2A%5Cfrac%7BgR%5E2%7D%7BR%2Bh%5E2%7D)
![F_h = \frac{F_WR^2}{(R+h)^2}](https://tex.z-dn.net/?f=F_h%20%3D%20%5Cfrac%7BF_WR%5E2%7D%7B%28R%2Bh%29%5E2%7D)
![F_h=\frac{(941.78)(6.371*10^6)}{(6.371*10^6+1841)}](https://tex.z-dn.net/?f=F_h%3D%5Cfrac%7B%28941.78%29%286.371%2A10%5E6%29%7D%7B%286.371%2A10%5E6%2B1841%29%7D)
![F_h = 941.50N](https://tex.z-dn.net/?f=F_h%20%3D%20941.50N)
The change of the Weight is,
![\frac{F-F_h}{F}*100=\frac{941.78-941.50}{941.78}*100=0.029\%](https://tex.z-dn.net/?f=%5Cfrac%7BF-F_h%7D%7BF%7D%2A100%3D%5Cfrac%7B941.78-941.50%7D%7B941.78%7D%2A100%3D0.029%5C%25)
The answer is B. Hemorrhage and Arthritis
Answer:
for a craft with a mass of 1500 kg.
Explanation:
Let consider that craft has a mass of 1500 kg. The submersible craft is modelled after the Newton's Laws, whose equation of equilibrium is:
![\Sigma F = T - W +F_{D} = 0](https://tex.z-dn.net/?f=%5CSigma%20F%20%3D%20T%20-%20W%20%2BF_%7BD%7D%20%3D%200)
The tension experimented by the cable while the craft is lowering to the seafloor is:
![T = W - F_{D}](https://tex.z-dn.net/?f=T%20%3D%20W%20-%20F_%7BD%7D)
![T = (1500\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)-1800\,N](https://tex.z-dn.net/?f=T%20%3D%20%281500%5C%2Ckg%29%5Ccdot%20%5Cleft%289.807%5C%2C%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%7D%20%5Cright%29-1800%5C%2CN)
![T = 12910.5\,N](https://tex.z-dn.net/?f=T%20%3D%2012910.5%5C%2CN)
Answer:
Displacement is the distance between an object’s initial position and its final position and is usually measured or defined along a straight line. Since this is a calculation that measures distance, the standard unit is the meter (m).
