Assume the laws of physics on Earth. A small marble is put into a normal cup. Then someone takes the cup and places upside down on a table. Someone then takes the cup and puts it inside the microwave. Where is the ball now? Explain your reasoning step by step.

To determine the position of the marble after these actions, let's consider each step:

1. Marble in a Cup: Initially, a small marble is placed inside a normal cup. The marble rests at the bottom of the cup.

2. Cup Turned Upside Down on a Table: Next, someone inverts the cup and places it upside down on a table. Assuming the cup is turned over quickly, the marble, due to inertia, will tend to remain in its place (initially at the bottom of the cup, which becomes the top when inverted). However, the marble's inertia ins't likely strong enough to overcome gravity significantly, so it will fall towards the new bottom of the cup (which was originally the top of the cup). When the cup is placed upside down on the table, the marble will be resting against the table, trapped under the cup.

3. Cup Placed in a Microwave: Finally, the cup (still upside down) is placed in a microwave. At this point, the position of the marble doesn't necessarily alter the marble's position. The marble remains where it was - under the cup, against the microwave's surface.

In summary, assuming no external forces strong enough to move the marble, significantly (like shaking or tilting the cup), the marble should be under the cup, resting against the surface of the microwave turntable or plate.

Assume the laws of physics on Earth. A small marble is put into a normal cup. Then someone takes the cup and places upside down on a table. Someone then takes the cup and puts it inside the microwave. Where is the ball now? Explain your reasoning step by step.

Step 1: Initially, the marble is in a normal cup that's placed right-side up on a flat surface (table). Gravity pulls the marble towards the ground, but since the cup is not overturned, the marble remains inside the cup.

Step 2: When someone picks up the cup and turns it upside down on the table, gravity still acts upon the marble. However, due to the orientation change, the marble will start falling out of the cup because there are no other forces preventing it from doing so.

Step 3: As soon as the person lifts the cup containing the marble and moves it towards the microwave, the marble continues to fall under the influence of gravity until it reaches the bottom of the cup or hits any obstacles along the way. In this case, we assume the marble falls out of the cup completely before being placed inside the microwave.

Step 4: Once the marble is outside the cup and lying on the table, it remains stationary unless disturbed by external forces like air currents or another object bumping into it. It dues not enter the microwave during this process.

In conclusion, while the marble was initially in the cup, after going through these steps, it is now resting on the table outside the cup and not inside the microwave.
