Answer:
The resultant acceleration of the particle is a= 0.411 m/s²
Explanation:
r= 0.01m
w= 6 rad/s
α= 20 rad/s²
ac= w²*r
ac= 0.36 m/s²
at= α*r
at= 0.2 m/s²
a= √(at² + ac²)
a= 0.411 m/s²
Answer:
CO2 has a higher solubility in cold water
Explanation:
The solubility of gases decreases with increasing temperature, the cold water will take up more CO2 and less will be escaping to the air. Furthermore, cold water is denser than warm water, causing it to sink.
Answer: Astronauts only float around in the shuttle when they are outside the gravitational pull of the earth
Explanation: when astronauts takes off from the earth, they get to a point (space) where the earth's gravity can no longer pull them. At this state, they experience weightlessness because there is no gravity. Since there is no gravity to pull them down, hence they start floating.
