The hot air balloon rises because it is

A stone is dropped from a stationary hot air balloon in the air travels 14.7m in the last second before it hits the ground. Find the height of the balloon from the ground.

The heated air inside a hot air balloon weighs 5000 N. If the balloon supports a weight of 2000 N, what is the wieght of air displaced by the balloon?

A: Hot air balloon rises up by displacing the denser air of the atmosphere. R: The given mass of a gas becomes less denser.

Mr. Naik is a paramilitary Intelligence Corps officer who is tasked with planning a coup on the enemy at a certain date. Currently he is inspecting the area standing on top of the cliff. Agent Vinod is on a hot air balloon in the sky. When Mr. Naik looks down below the cliff towards the sea, he has Ajay and Maran in boats positioned to get a good vantage point. The main goal is to scope out the range and angles at which they should train their soldiers. If the vertical height of the balloon from the top of the cliff is 12 m and angleb=30^(@) , then the distance between the Naik and vinod is

A man hangs from a rope attached to a hot-air balloon. The mass of the man is greater than the mass of the balloon and its constents. The system is stationary in air. If the man now clims up to the balloon using the rope, the centre of mass of the man plus balloon system will
