Okay So Blink your eyes. Was work done? Explain your answer.
I don't need you telling me this isn't a real question also I need this kind of work so please don't put anything that isn't useful for my assignment .


In physics, work is defined as a force causing the movement—or displacement—of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force. Though both force and displacement are vector quantities, work has no direction due to the nature of a scalar product (or dot product) in vector mathematics. This definition is consistent with the proper definition because a constant force integrates to merely the product of the force and distance.

Answers

Answer 1

Answer:

no work was needed. Blinking does not require using energy sometimes we blink without thinking.

Explanation:

Answer 2

Answer:

Yes work was done because muscles in your body contract and relax to make you move and blink. To just smile you use 32 or 36 muscles. The simplest movements are also sometimes to most complex.

transpiration
condensation
precipitation

Answers

Condensation formed the water droplets in scotts model

The phase change process of condensation formed the water droplets in Scott’s model.

What is condensation?

Condensation is a process of phase change in which gas molecules are converted to liquid molecules.

Condensation occurs due to the loss in heat and hence kinetic energy by the gas molecules.

In the water cycle model, after evaporation occurred in the water molecules, the process of condensation

formed the water droplets.

Therefore, condensation resulted in the formation of water droplets on the model.
