A particle moves along the x axis from xi to xf . Of the following values of the initial and final coordinates, which results in a negative displacement?

xi = −4m, xf = −2m

xi = −4m, xf = −8m

xi = 4m, xf = 6m

xi = −4m, xf = 2m

xi = −4m, xf = 4m

8 / 25

There is no SI base unit for area because:

we live in a three (not a two) dimensional world

area can be expressed in terms of square meters

it is impossible to express square feet in terms of meters

an area has no thickness; hence no physical standard can be built

area is not an important physical quantity

The average speed of a moving object during a given interval of time is always:

the magnitude of its average velocity over the interval

the distance covered during the time interval divided by the time interval

one-half its acceleration multiplied by the time interval.

one-half its speed at the end of the interval

its acceleration multiplied by the time interval

16 / 25

In 1866, the U. S. Congress defined the U. S. yard as exactly 3600/3937 international meter. This was done primarily because:

the members of this Congress were exceptionally intelligent

this definition relates the common U. S. length units to a more widely used system

there are more wavelengths in a yard than in a meter

length can be measured more accurately in meters than in yards

the meter is more stable than the yard
