true or false. I- The speed of light in vacuum is a universal constant, whose value (without uncertainty, as it is defined as a standard) is c=299792458 m.s -1..The value of c in scientific notation is 2.99792458 x108 m.s-1. II- The value of c (velocity of light in vacuum) written to 3 significant figures is 3.00 x 108 .m.s-1. III- The value of the density of an object obtained was ρ±uρ=(7.768581114 ± 0.012540242) g.cm -3. The value obtained for the density and its respective uncertainty is incorrect, as it makes no sense to report the uncertainty with so many decimal places. IV- To convert g/cm 3 to kg/m 3 just multiply by 10 3.
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
