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.
Answer:
If there is a net force acting on an object, the object will have an acceleration and the object's velocity will change. ... Newton's second law states that for a particular force, the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object.
Explanation:
Answer:
20.6 N
Explanation:
Friction equals normal force times coefficient of friction.
F = Fn μ
On level ground, normal force equal weight.
Fn = W
Therefore:
F = W μ
F = (685 N) (0.0300)
F = 20.6 N
It changes because force is somewhat like pressure. Force is continuously against the object so as a result, speed changes .
Answer:
3N/C
Explanation:
Thinking process:
Let, electric field of 4N/C is in the positive x direction, that is + 4 NC
And the the resulting electric field on the x axis at x =2m
Therefore, based on the data above, the net charge must be in the positive direction. Thus, the magnitude is given by the equation:
Now considering that at x = + 4 NC, the net charge will be:
