The laws of momentum. The boat is on a frictionless surface (water). The engine turns the propeller, which forces water backwards at speed. Since there is nothing to stop the boat moving - it moves forwards.

What relation do you find between the weight of the floating body and the waight of water that is displaced?

They are equal.When a boat is floating on water it displaces water equal to its weight(Archimedes Principle). As the density of water is less than boat so water displaced is greater than volume of boat. When the boat sinks water displaced is equal to volume of boat. So less water is displaced in 2nd case and consequently water level goes down.Note - relation between volume(v) mass(m) and density(d) : d = m/v

At least 320 J


How many knots is 15hp?

Doesn't work like that. 15 hp is the power of the motor, but the speed you get from 15 hp would depend on how hard it is to push the boat through the water. 15 hp on a canoe would be scary fast while 15 hp on a barge won't do a thing.

What are the principles of organising?

The principles of organizing include division of work, which promotes specialization and efficiency; unity of command, ensuring that employees receive orders from only one superior to avoid confusion; and the scalar principle, which establishes a clear hierarchy of authority. Additionally, the principle of flexibility allows organizations to adapt to changing environments, while the principle of coordination ensures that different departments and functions work together effectively. These principles help create a structured and efficient organizational framework.
