Question

define thrust and pressure and becoyancy and dentasy​

Answer 1

Answer:

Thrust: Force exerted by an object perpendicular to the surface is called thrust. Pressure: Pressure is defined as thrust or force per unit area on a surface. ... SI unit of pressure is called Pascal (Pa)

Answer 2

Answer:

1. Thrust = Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction, to be applied to that system
2. pressure = the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre
3. becoyancy = the tendency of a body to float or to rise when submerged in a fluid testing an object's buoyancy. b chemistry : the power of a fluid to exert an upward force on a body placed in it the buoyancy of water also : the upward force exerted.
4. density = The density, of a substance is its mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used.
