Question

Bill Nye The Science Guy Pressure

Hello if anyone saw the video before please help me in the video he is talking too fast for me to get the answers 1. Hovercrafts floats and rockets fly because of Pressure.

2. Water pressure in the bucket, tube and container is the ___________________, but if you hoist the bucket, the water pressure ______________________. This causes the bricks to __________________.

3. _________________ make the pressure on fireboats.

4. _______________________ exert pressure on a small surface area causing the woman to sink in the mud. _________________ spread the pressure over a large area and allow the woman to cross the swamp safely.

5. Room pushes the card upholding the water in the glass

6. ________________ in the room holds the arrow to the glass. Under the suction cup a _________________ is formed.

7. A ___________________ holds the lid on the container tightly enough that it can support Bill’s weight.

8. In the experiment with the water and the glass, the size of the glass and board does/does not matter. Air pressure will/will not hold the cardboard on the glass.

9. Vacuums work because the air in the room has Air pressure and inside the machine, there is ______________ pressure.

10. You can drive a nail into a board by the pointed end because it has _______ area and ________ pressure …but not by the flat end because that end has ________ area and ________ pressure.

11. High pressure water and sand can cut_____________________ and ________________.

12. The air in the cup is compressed when Bill dives to the bottom of the river because the water pressure at the bottom of the river is ____________ than the pressure at the top of the river.

Answer 1

Answer is as follows

Step-by-step explanation:

1. Pressure is responsible for making hovercrafts float and rockets fly.

2. Water pressure in the bucket, tube and container is the same at the bottom, but if you hoist the bucket, the water pressure decreases. This causes the bricks to fall.

3. Firehoses make the pressure on fireboats.

4. High heels exert pressure on a small surface area causing the woman to sink in the mud. Snowshoes spread the pressure over a large area and allow the woman to cross the swamp safely.

5. Air pressure in the room pushes the card upholding the water in the glass.

6. Suction in the cup in the room holds the arrow to the glass. Under the suction cup, a vacuum is formed.

7. A vacuum holds the lid on the container tightly enough that it can support Bill's weight.

8. In the experiment with the water and the glass, the size of the glass and board does not matter. Air pressure will hold the cardboard on the glass.

9. Vacuums work because the air in the room has air pressure and inside the machine, there is lower pressure.

10. You can drive a nail into a board by the pointed end because it has less area and more pressure...but not by the flat end because that end has more area and less pressure.

11. High-pressure water and sand can cut steel and glass.

12. The air in the cup is compressed when Bill dives to the bottom of the river because the water pressure at the bottom of the river is greater than the pressure at the top of the river.
