What is the reaction force when you place a cup on a table?
The reaction force when you place a cup on a table is the force exerted by the table on the cup in the opposite direction to the force applied by the cup on the table. This force prevents the cup from falling through the table and keeps it in place.
How do you flip a cup of water without dropping any water?
To flip a cup of water without dropping any water, you need to increase the speed of the flip so that the force keeps the water in the cup against the pull of gravity. This requires practicing the right technique and mastering the motion to create a controlled flip that does not spill any water. It also helps to use a cup with a wide opening to provide more stability during the flip.
When a cup is filled with water with a card on top of it is turned upside down the water does not fall out why?
When the cup is flipped upside down with the card on top, air pressure pushes up on the card, preventing the water from falling out. The air pressure inside the cup is greater than the force of gravity trying to pull the water out. This creates a seal that keeps the water in place until the card is removed.
How does water stay in a cup upside down?
When a cup is flipped upside down, the water remains inside due to air pressure. The pressure pushing down on the water is greater than the force of gravity pulling it out of the cup, creating a seal and preventing the water from falling out.
what type of cup keeps hot water hottest Paper or metal?
A metal cup will generally keep hot water hotter for longer compared to a paper cup. Metal is a better insulator than paper, so it helps to retain heat more effectively.
When you twirl a cup of water at 360 degrees why doesn't the water not come out?
When a cup of water is twirled at 360 degrees, the centripetal force created by the motion of the cup keeps the water inside. This force acts inward, preventing the water from spilling out even when inverted. As long as the centripetal force is greater than the force of gravity pulling the water downward, it will remain in the cup.
What is the reaction force when you place a cup on a table?
The reaction force when you place a cup on a table is the force exerted by the table on the cup in the opposite direction to the force applied by the cup on the table. This force prevents the cup from falling through the table and keeps it in place.
Which cup keeps water warmest after 10 minutes?
styrofoam keeps the water warm hahAHAHAHA
What colour cup keeps hot water the hottest?
white

When you twirl a cup 360 degree's why does the water not fall out?
You are right, you can flip a cup very fast and no water will fall out. Depending on how you flip it, that is. Due to centripetal force, the water "wants" to spread away from the axis of rotation. If the axis is the top of the cup, the water is off center and will just be pushed toward the bottom, from which it cannot escape. If the axis is the water, it will probably fall out a little bit, but not all of it. The cup is most likely spinning too fast for it to fall out. Once the water starts to fall, it is caught again. :D
Why will an ice cube placed in a cup of hot rotating water spin automatically faster than the water itself?
the center of a whirlpool is spinning the fastest. the cube is in the center so its spinning equal or a lil slower than the water directly under it but the water neer the edge of the cup is spinning slower.....put something in the toilet, flush it and observe how it spins faster as it reaches the center...........use something that wont clog the toilet
When a cup is filled with water with a card on top of it is turned upside down the water does not fall out why?
When the cup is flipped upside down with the card on top, air pressure pushes up on the card, preventing the water from falling out. The air pressure inside the cup is greater than the force of gravity trying to pull the water out. This creates a seal that keeps the water in place until the card is removed.
How does placing a lid over a hot cup of water keeps it warm?
no it do not keep it longer
Which cup keeps water cooler metal or plastic cup?
metal cup because it has insulation
When a cup of water held upright is dropped the water stays in the cup until it hits the ground.?
Yes, they both fall at the same rate because the force of gravity is the same for both the cup and the water. True
Which type of cup keeps hot water hottest polystyrene plastic paper or metal?
paper
