The net force on the block acting perpendicular to the incline is
∑ <em>F</em> = <em>n</em> - <em>w</em> cos(29.4°) = 0
where <em>n</em> is the magnitude of the normal force and <em>w</em> = <em>m g</em> is the weight of the block.
The equation itself comes from splitting up the forces acting on the block into components pointing parallel or perpendicular to the incline. The only forces acting on the block in the perpendicular direction are the normal force and the perpendicular component of the block's weight.
Solve for <em>n</em> :
<em>n</em> = <em>m g</em> cos(29.4°)
<em>n</em> = (6 kg) (9.80 m/s²) cos(29.4°)
<em>n</em> ≈ 51.2 N

Answer:
it snaps
Explanation:
the more force you put on it, the wired out it gets than it snaps. I think
Answer:
3.87 or 3.9 mg
Explanation:
2.7h * 60mins = 162mins
number of 1/2 lives = 162/22= 7.364
amount remaining = 639(1/2)^7.364 = 3.8796
answer = 3.87 or 3.9
