Pictures of individuals in which their face and expression are the primary focus. 2. What are candid shots? What are posed shots? Compare and contrast some of the advantages and disadvantages to these two approaches. Candid shots are taken when the person is unaware that the photograph is being taken.

and not somewhere else then that means it wasn’t moving. Therefore no motion was taking place. He states the same conclusion as the previous argument which was the same as the first argument‚ the Dichotomy that motion is nonexistent. This brings the idea that there is no plurality because to be and not to be are the same but not the same‚ there is no space so there is no plurality. This argument is flawed because rest and motion are different and what is happening at present time has nothing to do

TYPES OF CUTTING MOTION IN MACHINE TOOLS A machine tool is a machine for making components of a given shape‚ size and accuracy as per the requirements by removing material from the workpiece by using a cutting tool to operate upon the workpiece. Machine tools are capable of producing themselves therefore the machine tools are quite often referred to as mother machine. In the manufacturing processes‚ machine tools are the most versatile and almost any product can be produced with them. The machine

Newton’s First Law of Motion states‚ “Every object continues in a state of rest‚ or in motion in a straight line at constant speed‚ unless it is compelled to change that state by an unbalanced force exerted upon it.” The change was the thrust made when the straw was released. •Newton’s Second Law of Motion states‚ “The acceleration produced
