Problem 1.72

Give the derived SI units for each of the following quantities in base SI units:

(a) acceleration = $$\text { distance/time }{ }^{2}$$

(b) force = mass $$\times$$ acceleration

(c) work = force $$\times$$ distance

(d) pressure = force/area

(e) power = work/time

(f) velocity = distance/time

(g) energy = mass $$\times(\text { velocity })^{2}$$

Text Transcription:

distance/time ^{2}

\times

\times (velocity) 2

Step-by-Step Solution:

Step 1 of 5) Matter exists in three physical states, gas, liquid, and solid, which are known as the states of matter. There are two kinds of pure substances: elements and compounds. Each element has a single kind of atom and is represented by a chemical symbol consisting of one or two letters, with the first letter capitalized. Compounds are composed of two or more elements joined chemically. The law of constant composition, also called the law of definite proportions, states that the elemental composition of a pure compound is always the same. Most matter consists of a mixture of substances. Mixtures have variable compositions and can be either homogeneous or heterogeneous; homogeneous mixtures are called solutions.Each substance has a unique set of physical properties and chemical properties that can be used to identify it. During a physical change, matter does not change its composition. Changes of state are physical changes. In a chemical change (chemical reaction), a substance is transformed into a chemically different substance. Intensive properties are independent of the amount of matter examined and are used to identify substances. Extensive properties relate to the amount of substance present. Differences in physical and chemical properties are used to separate substances.Energy is defined as the capacity to do work or transfer heat. Work is the energy transferred when a force exerted on an object causes a displacement of that object, and heat is the energy used to cause the temperature of an object to increase. An object can possess energy in two forms: kinetic en
