Answer:
Magnitude is 25.8 m/s and direction is 
Explanation:
From the law of conservation of linear momentum
where
and
are masses of bullet and stones respectively,
and
are the initial velocities of bullet and stone respectively,
and
are the final velocities of bullet and stone respectively
Substituting 6g=0.006 Kg for mass of bullet, 0.1Kg for mass of stone, 350 m/s for initial velocity of bullet and 250 m/s as final velocity for stone but initial velocity of stone is zero
Substituting 21 for
and 15 for
To find direction
Therefore, magnitude is 25.8 m/s and direction is
Answer: the element with the lowest electronegativity
Explanation:
k e is energy of movement. When thing solidifies, atoms stop moving ke is less.
That's true, you can't get any more precise than what's measured to the least precision.
