In this problem, you’re given a mass (m) and a force (F) applied to an object and you’re asked to calculate the acceleration (a). If we plug this into the provided equation:

F = ma
(7.3 N) = (3.2 kg)a
a = 2.3 m/s/s

The acceleration of the object is 2.3 m/s/s.

Hope this helps!

Which compound has a molecular ion at m/z = 58, an infra red absorption at 1650cm^-1?
rewona [7]

CH_{3}COCH_{3} (acetone) has a molecular ion at m/z = 58, an infra red absorption at 1650cm^-1

Acetone is a synthetic substance that is also naturally present in the environment. It is a tasteless, colourless liquid with a distinct odour. It is combustible, readily evaporates, and dissolves in water. It is also known as beta-ketopropane, 2-propanone, and dimethyl ketone. Plastic, fibres, medications, and other compounds are all made from acetone.

Other substances can also be dissolved with it. It is a byproduct of the breakdown of human fat and is found naturally in plants, trees, volcanic gases, forest fires, and other organisms. It can be found in landfills, tobacco smoke, and automobile exhaust. Acetone is released into the environment more through industrial processes than through natural ones.
