What is a common use for the physicians desk reference pdr

The PDR is  a thick volume that commonly used to provide guidance for prescription drugs available in the United states. The PDR is the most commonly used drug reference . The information is the same as the leaflet found in the drug package also known as the package insert.  Drug companies pay to have their drugs included, so many generic medicines will not be found in the book.

For over 60 years, physicians and researchers have turned to PDR for the latest word on prescription drugs. It includes comprehensive and up-to-date information on more than 4000 FDA approved drugs.

0.25m/s2

Explanation:

Acceleration is simply the change in velocity per unit time. It is expressed mathematically as:

Acceleration (a) = change in velocity (ΔV) / time (t)

a = ΔV/t

Data obtained from the question include:

Change in velocity (ΔV) = 20 m/s

Time (t) = 80 secs

Acceleration (a) =.?

Applying the equation a = ΔV/t, the acceleration of the bus can be obtained as follow:

a = ΔV/t

a = 20/80

a = 0.25m/s2

Therefore, the acceleration of the bus is 0.25m/s2
