Physics Primer

In an experiment you are performing, your lab partner has measured the distance a cart has traveled: 28.4inch28.4inch. You need the distance in units of centimeter and you know the unit equality 1inch=2.54centimeter1inch=2.54centimeter. By which conversion factor will you multiply 28.4inch28.4inch in order to perform the unit conversion?

2.54centimeter/1inch

What is the Physics Primer?

A set of mathematics topics that are relevant to introductory physics courses.

Determine the values of mm and nn when the following charge of a proton is written in scientific notation: 0.000000000000000000160 CC.

m,n = 1.60,-19

The mass of a high speed train is 4.5××105 kgkg, and it is traveling forward at a velocity of 8.3××101 m/sm/s. Given that momentum equals mass times velocity, determine the values of mm and nn when the momentum of the train (in kg⋅m/skg⋅m/s) is written in scientific notation.

m,n = 3.7,7

Determine the values of mm and nn when the following average distance from the Sun to the Earth is written in scientific notation: 150,000,000,000 mm.

m,n =1.5,11

Determine the values of mm and nn when the following average magnetic field strength of the Earth is written in scientific notation: 0.0000451 TT.

m,n =4.51,-5

Given that average speed is distance traveled divided by time, determine the values of mm and nn when the time it takes a beam of light to get from the Sun to the Earth (in ss) is written in scientific notation. Note: the speed of light is approximately 3.0××108 m/sm/s.

m,n =5.0,2

Determine the values of mm and nn when the following mass of the Earth is written in scientific notation: 5,970,000,000,000,000,000,000,000 kgkg.

m=5.97 n=24
