What is the acceleration of an airplane maintaining a constant speed of 67.7 m/s?

Zero

Explanation:

The acceleration of the plane is given by:

where

is the change in velocity

is the time taken

In this problem, we are told that the airplane is traveling at constant speed, so (assuming it is traveling in a straight line*), its velocity is not changing. Therefore, and the acceleration is zero.

*if the airplane is changing direction, then its velocity is changing (because velocity is a vector), so the acceleration in this case would not be zero.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

i think the answer is tomato juice? not entirely sure though
