What else can I help you with?
Why when you release an inflated but untied balloon does it fly across the room?
When an inflated but untied balloon is released, the air inside the balloon pushes against the walls of the balloon, propelling it forward. This creates a force that causes the balloon to move in the opposite direction. The unbalanced forces result in the balloon flying across the room.
What is an example of static electricity contact?
A balloon sliding across your hair
Dragging your feet across the carpet or rubbing your head with a balloon creates the most static electricity?
Rubbing your head with a balloon creates more static electricity than dragging your feet across the carpet. This is because the friction between the balloon and your hair generates a larger amount of static charge.
Would sailing across the Pacific Ocean be more dangerous than flying in a hot air balloon across the Pacific Ocean?
No, as winds can be turbulent. Should the balloon lose altitude, it would probably not float for very long.
Why a balloon don't pop on many thumbtacks?
When a balloon is filled with air, the pressure inside the balloon is evenly distributed. When many thumbtacks are inserted into the balloon, the pressure is still distributed across the surface of the balloon, preventing it from popping. Each thumbtack only affects a small area of the balloon, so the overall pressure remains relatively balanced.
In which direction does gases exert pressures?
All directions equally. Think of how a balloon blows up..... It expands with equal force all across the area of the balloon.
Why popping a balloon with a pin is easier than stepping on it with?
Popping a balloon with a pin requires less force because the pin concentrates the pressure to a small area, piercing the balloon easily. Stepping on a balloon distributes your weight across a larger area, making it harder to apply enough force to pop the balloon.
Will an electric charge spread over and entire balloon?
Yes, an electric charge can spread over the entire surface of a balloon. When a balloon is charged, the charge will distribute itself evenly across the surface due to electrostatic forces.
How many miles is continental US across from east to west?
The US tapers from about 3200 miles across in the north to about 2500 miles across in the south.
What body of water was Larry Newman the first to pilot a balloon across in 1981?
The Pacific Ocean
What three national parks lie across the Continental Divide?
There are three national parks that lie across the continental divide. Glacier National Park is one. Yellowstone National Park and Rocky Mountain National Park are the other two.
How hot is the Earth's continental crust?
The temperature of the continental crust varies widely across different areas and at different depths.
