Answer:
-0.105 m/s
Explanation:
Given that
Mass of the astronaut, m(a) = 68.5 kg
Mass of the tool, m(t) = 2.25 kg
Speed of the tool after it is thrown, v(t) = 3.20 m/s
We know that momentum of a particle,
p = mv
See the attachment for calculations
Therefore, the speed is 0.105 m/s and it moves in the opposite direction.
Answer:
Particle spacing increases and it's called evaporating
Answer: uhhhhhhh what is this for?
Explanation i so confused
Answer:
1. C: 31/14 Si becomes 31/15 because a nuetron
2. A: 238 92U because the very long half-life means a very small rate of decay
3. D: Charge conservation is not satisfied
4. B: of the four nuclear decay processes only the α-decay changes the baryon number and does so in increments of four
Explanation:
I just took the quick check. Enjoy the answers I did not get to have
Answer:
C. precipitation
Explanation:
if clouds store too much water from evaporation, it will rain which is precipitation
