Answer:
B - A
Explanation:
For the combination of 2 vector to due southwest, 1 vector must due south and the other vector due west. Since vector B is already due west, vector A should due south. As vector A is already due north, vector -A would due south. So the combination of B + (-A) or B - A should points southwest
Answer:

Answer:
Explanation:
We have given the rest mass of SPARTYON = 945 times of mass of electron
We know that mass of electron 
So mass of SPARTYON 
Speed of light 
According to Einstein equation energy is given by
Now according to planks's rule
Energy is given by
, here h is plank's constant 
So 
Answer:
Kinetic energy would increase by a factor of 4 where as momentum would increase by a factor of 2.
Explanation:
Kinetic Energy is given by 0.5*mass*velocity^2. Kinetic Energy is proportional to Velocity^2.
Momentum is given by mass*velocity. Momentum is proportional to Velocity.
If the velocity of an object is doubled, Kinetic energy would increase by a factor of 2^2 i.e 4 times. Momentum would increase by a factor of 2.
