What must happen for a balloon to float in the air?
For a balloon to float in the air, it must be filled with a gas that is lighter than the surrounding air, such as helium or hot air. This creates a buoyant force that allows the balloon to rise and float.
A balloon weighs 1N is suspended in the air drifting neither up nor down How much buoyant force acts on it?
The buoyant force acting on the balloon is equal to its weight, which is 1N. This is because the balloon is in equilibrium, with the buoyant force balancing the weight of the balloon, so it does not move up or down.
On a perfect fall day you are hovering at low altitude in a hot-air balloon accelerated neither upward nor downward The total weight of the balloon is 17500?
The buoyant force exerted by the air on the balloon must be equal to the weight of the balloon in order to maintain a constant altitude. This means that the buoyant force is 17500 N and it is balancing the weight of the balloon. If the buoyant force decreases for any reason, the balloon would start to descend.
Why does an negativity charged balloon stick to a wall?
When you rub the balloon on your hair, or on another similar surface, the balloon becomes negatively charged. The wall itself doesn't have any particular charge, and doesn't conduct electricity. When you place the balloon on the wall, the molecules in the wall polarize, that is, positive and negative charges in the molecule separate and go to opposite sides of the molecule. Opposite charges attract, and like charges repel, and since the negative charges in the molecules are pushed away from the balloon and the positive ones are pulled towards it, the attraction force is greater than the repulsion force and the balloon is held to the wall.
What are the action and reaction forces that occur when letting go a balloon?
Before you open the hole, every force pushing inside the balloon is balanced by an equal force in the opposite direction on the opposite inside surface of the balloon, so the balloon goes nowhere. Open the vent, and suddenly there is an imbalance because there is still pressure on the inside wall opposite the vent, and the ballon accelerates in that direction. All rocket engines work that way: continuous supply of pressure, with one end of the chamber open.

How does a meter stick with a balloon on top balance on your finger?
A meter stick with - or without - a balloon on top balances on your finger when the sum of torques around the support point equals zero. When the support is an extended object such as a finger, the meter stick will be balanced when a line drawn toward the center of the planet from the point around which the sum of torques is zero is within the supported zone. Torque results from a force being applied at a distance from the point under consideration. When using a massive object such as a ruler as a backbone for torques, one must consider the mass of the ruler. For the purposes of torque calculations, consider the weight of the ruler to act at the center of gravity of the ruler and to point towards the center of gravity of the object which gives the ruler weight. In most cases that object will be Earth. If one's measurements are very sensitive, one must take into consideration surface features such as near by mountains, latitude and cetera...
What are the examples of balance force?
If the forces on an object are balanced, it won't move. This would apply to a captive balloon, held to the ground by a rope. The upward force of the balloon's buoyancy is balanced by a downward force in the rope, and these must be equal. The same argument for you sitting still in your chair, your weight is balanced by an upward force in the chair.
What are the rules to the balloon game?
There are many variations to the balloon game, it can be balloon soccer, balloon races and/or balloon stomp. The common game's main rule is that they must pass the balloon but not the ribbon.
What is it meant by big stick diplomacy and how is that related to the Roosevelt's corollary?
Roosevelt, in his corollary to the Monroe Doctrine, stated we must "Speak Softly and Carry a Big Stick." Basically, this means that we must negotiate diplomatically but be ready to use force (a stick) when necessary while negotiating with foreign powers.
Why must the open end of the balloon face backwards if you want the car to move forward?
Because of Newton's law. This states that every action must have an equal and opposite reaction. Thus facing the balloon backwards when attached to the car and letting the air out causes the air mass in the balloon to be expelled BACKWARDS. The law then says that the car must be pushed FORWARDS with an equal force. This is how a space rocket works.

How does a balloon powered race car apply to Newton's laws of Motion?
A balloon rocket lab demonstrates one of Newton's Laws, because as Newton's Third Law states:"For every action, there is an opposite and equal reaction."When the balloon rockets over the string, the air being released from the balloon is forcing against the air, and the air is producing an opposite and equal reaction, which pushes the balloon forward. The air being released from the balloon is pushing against the air, and the air is stopping the air coming out of the balloon, essentially propelling the balloon.That is how it demonstrates one of Newton's Laws (3rd Law, to be specific).
