Answer:
Bubbles paused
Explanation:
the air bubble doesn't rise because it is no lighter than the water around it—there's no buoyancy. The droplet doesn't fall from the leaf because there's no force to pull it off. It's stuck there by molecular adhesion.
for instance, onto the International Space Station, gravity becomes negligible, and the laws of physics act differently than here on Earth
On Earth, the buoyancy of the air bubbles causes them to rise to the top together, creating a segregation between air and water. However, in microgravity, nothing forces the air bubbles to interact and thus rise together, Green said.
Acceleration of the table: B. 0.50 meters/second2
Explanation:
The problem can be solved by using Newton's second law of motion, which states that the net force acting on an object is the product of its mass and its acceleration. Mathematically:
where
is the net force
m is the mass
a is the acceleration
For the table in this problem, we have:
is the net force on the table, because there are two forces of 125 N and 120 N acting in opposite directions
m = 10.0 kg is the mass of the table
Solving for a, we find the acceleration:

Answer:
69.42 m
Explanation:
From the question given above, the following data were obtained:
Initial velocity (vᵢ ) = 4.9 m/s
Acceleration (a) = 4.2 m/s²
Time (t) = 4.7 s
Displacement (Δx) =?
Thus, we can obtain the displacement by using the following formula:
Δx = vᵢt + ½at²
Δx = (4.9 × 4.7) + (½ × 4.2 × 4.7²)
Δx = 23.03 + (2.1 × 22.09)
Δx = 23.03 + 46.389
Δx = 69.419 ≈ 69.42 m
Thus, the distance travelled is 69.42 m
