You need to say the right things to said character and you have to be nice to them and do their loyalty mission...
Yes, you can have a relationship with Jack.
cause and effect
In "Mass Effect 2," building and maintaining a relationship with a squad member involves engaging in conversations, completing their loyalty missions, and making choices that align with their values. Once the game is completed, you can continue your relationship in "Mass Effect 3" by importing your save file. This allows you to further develop the relationship and experience new interactions based on the choices made in the previous game. Remember, the relationships can significantly influence the storyline and character interactions in the sequel.
Of course yes! Just think of the formula for density! Density=mass/volume! There is a direct relationship between density and mass (directly proportional)!
No measurable effect at all. The electrons which cause the negative charge have such an unbelievably small mass that billions of them cannot make any observable change to the mass.
If he died in Mass Effect 1 then he is not in Mass Effect 2. If he survived Mass Effect 1 he shows up in Mass Effect 2 but he can not be killed.
Yes you can, it doesn't make a difference.
If you played Mass Effect 1 the second game imports your old game save, so it would depend on how you played Mass Effect 1 as to whether or not Kaiden is alive. If you did not play Mass Effect 1, then the game will default to the character with the opposite gender to Shepard. So Ashley will be there with a male Shepard, Kaiden for a female one. Below is a link which has the important decisions you make in 1 and their effect in the sequel.
well the relationship between mass and force is..........*relationship... Force=mass x acceleration
Jeff "Joker" Moreau is never really threatened or in need of "saving" in the Mass Effect series. This question does not really make sense.
The effect of mass extinction is extinction, death of a mass
Yes, there will be a Mass effect 3. even if your Shepard died, there will be a mass effect 3.
