Write at least name of five devices which work under the principles of physics.

1. A body submerged in liquid is buoyed up by the force equal to the weight of displaced liquid: Archimedes' Principal of Buoyancy. 
2. If an object such as a spring is elongated by a distance of x, then the restoring force f is exerted by the object proportionate to x: Hooke's Law of Elasticity.
3. Pressure, flow speed, and height can change the rate of flow: Bernoulli's Principal.
4. Total pressure of a mix of gasses in a container is equal to separate pressures serrate gasses would exert of one occupancy: Dalton's Law of Partial Pressures.
5. Heat flow is proportionate to the gradient of temperature difference: Fourier's Law of Heat Conduction.
