Answer:
C
Explanation:
Given that a liquid at rest in a fixed container exerts a force perpendicular to the wall of the container. Two students make claims about the microscopic cause of this force. Student A says that the force exerted by individual molecules as they bounce off the wall is always perpendicular to the wall. Student B says that the molecules may strike the wall at angles that are not perpendicular. Which student is correct and why?
The correct answer is option C
Student B . The molecules in a liquid are in random motion at the microscopic scale. For every atom that hits at an angle to one side of perpendicular, there is likely to be another atom hitting at the same speed at the same angle on the other side of perpendicular. On average the nonperpendicular components cancel
Here is the answer that completes the statement above. We can study how galaxies evolve because THE FARTHER AWAY WE LOOK, THE FURTHER BACK IN TIME WE SEE. This means that the more we discover more about what's happening in the universe, the more we become curious to know how and when it began. Hope this helps.
Answer:
F = 2553.6 N
Explanation:
v² = u² + 2as
0² = 16² + 2a4.0
a = -32 m/s²
F = ma = 79.8(32) = 2553.6 N
The magnetic field is a field of magnetism that is in constant contact with everything and it is stronger at the poles of the earth. compasses point towards magnetic north which is a few miles away from true North. refrigerator magnets are much much stronger then the magnetic field so that is why they stick to metal. I do not know what the domain theory is.
