False. Force and pressure are related concepts but not the same. Force is a push or pull on an object, while pressure is the force applied over a given area. Pressure is a measure of how force is distributed on a surface.
True. Pressure is defined as force per unit area. By decreasing the area on which a force acts, the same force applied will result in a higher pressure. This is known as the pressure-area relationship.
a) pressure
False. The force exerted by air on the top of your head is due to air pressure, which is typically around 1000 N per square meter. However, the actual force exerted on the top of your head would be much less than 1000 N unless your head has a very large surface area.
FALSE
The actor's performance in the play was a tour de force, captivating the audience with his skill and talent.

True.
True. Waves are the primary force of erosion along coasts, as their energy and movement cause the wearing away of the land through processes like abrasion, hydraulic action, and attrition.

The one with the highest pressure and largest area will produce the most force.
The statement is false because in a hydraulic system, the force on the larger piston is greater than the force on the smaller piston, even though the pressure is the same. This is due to the difference in cross-sectional area between the two pistons, which results in a mechanical advantage that allows the larger piston to exert a greater force.
