Answer:
Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy
Explanation:
If you're wearing steel-toe boots and you don't shatter some toes or a leg, then the object's acceleration is 10.58 m/s^2 ... but ONLY as long as your toe is touching it.
That acceleration is slightly greater than 1 G and your toe is not accelerating at that rate. So the object will get away ahead of your toe very quickly, and as soon as the contact breaks, the object stops accelerating.
To solve:
Create a proportion: 2:4=x:y
(Simplified) 1:2=40:y
Multiply, then solve:
Y=80
Answer: 80 grams of element Y would combine with 40 grams of element X to form the compound XY.
(A) The final velocity is
So the elevator has final velocity 0 (and no direction).
(B) The distance moved is
where
the initial velocity,
acceleration, and
time.
So we get
so the elevator moved 18 meters upwards.
