Answer:
The of the lander would be 75.66 pounds
Explanation:
From the question we are given that the
Weight of the Philae on Earth is = 220 pound-mass
gravity of Mars is = 3.71 m/![s^{2}](https://tex.z-dn.net/?f=s%5E%7B2%7D)
Weight of the Philae on Mars is = ?
Now Mass is quantity of matter in an object so it is always constant for a particular object
Generally Weight = Mass × Gravity :
![\frac{Weight Of Earth}{Gravity Of Earth} = \frac{Weight Of Mars}{Gravity Of Mars}](https://tex.z-dn.net/?f=%5Cfrac%7BWeight%20Of%20Earth%7D%7BGravity%20Of%20Earth%7D%20%3D%20%5Cfrac%7BWeight%20Of%20Mars%7D%7BGravity%20Of%20Mars%7D)
Hence
Weight of the Philae on Mars is = ![\frac{Weight Of Earth *Gravity Of Mars}{Gravity Of Earth}](https://tex.z-dn.net/?f=%5Cfrac%7BWeight%20Of%20Earth%20%2AGravity%20Of%20Mars%7D%7BGravity%20Of%20Earth%7D)
![=\frac{200 *3.71}{9.81}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B200%20%2A3.71%7D%7B9.81%7D)
![= 75.66 pounds](https://tex.z-dn.net/?f=%3D%2075.66%20pounds)
Answer:
1. Yes.
2. Localized corrosion
Explanation:
Should she be worried about corrosion?
Yes, the engineer needs to be worried about corrosion as stainless steel has a lower resistance to corrosion, in other words, stainless steel corrodes faster than Titanium.
If so, what types of corrosion could take place?
The type of corrosion that takes place is called Localized corrosion. Localized corrosion occurs when a small part of a component experiences corrosion. In this case, the ball component of the femoral stem is made of stainless steel which will corrode faster than the other parts of the femoral stem which is made of Titanium.
