How wavelength and wave period can be used to calculate wave speed?
Just divide the wavelength by the wave period, and you've got the wave speed.
What is the frequency of a wave whose period is 4 x 10-7 seconds?
The frequency is the reciprocal of the period; in this case, divide 1 / 4x10-7.
Would you divide or multiply by 60 to find how many hours are driven to and from work in a five day period?
Assuming your figures are in minutes then you would divide by 60 to convert them into hours.
How do you calculate dollar per store per week?
You need to know . . . > the total number of dollars during the period of interest, > the total number of stores, > the number of weeks in the period of interest. When you have collected that information . . . > Divide the total number of dollars by the total number of stores. then > Divide the result by the number of weeks in the period of interest. The result is dollars per store per week during that period.
How do you calculate average speed over a period of time?
Divide the total distance traveled by the total time elapsed. Hint: If you're looking for miles per hour (miles/hour), divide miles by hours.
What are the four geological time intervals?
Eons, Eras,Epochs, and period
How long do epochs last?
Magnetic epochs last a long period of time, geologically. It is when the earth's magnetic field is the same polarity.
Shorter than a period on the geologic time scale?
epochs
Which time scale divided the history of the earth into eras periods and epochs?
The geological time scale is the history of the earth. This is in the eras period and epochs.
Which eras on the geologic time scale is divided into both periods and epochs?
The Paleozoic, the Mesozoic and the Cenozoic are all divided into periods and epochs.
Eras are divided into periods which can be further divided into?
Eras divide into periods and periods divide into epochs. The Palaeozoic Era is composed of the Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian periods (in that order). The Mesozoic Era is divided into the Triassic, Jurassic and Cretaceous periods. The Cenozoic Era is divided into the Tertiary and Quaternary periods. The Tertiary period is divided into the Palaeocene, Eocene, Oligocene, Miocene and Pliocene epochs while the Quaternary period is divided into the Pleistocene and Holocene epochs. Note that eras are not the longest lengths of time. Eras may compose longer stretches of time known as eons/aeons.
What are the three time periods humans have been in?
The human have only been here for one period which is Neogene period in Cenozoic era.Neogene period is divided into 4 epochs.The genus Homo has been traced for following 3 epochs: Holocene, Pleistocene and Pliocene epochs.
What period was after the cretaceous?
The period after the Cretaceous is the Paleogene period, which is part of the Cenozoic era. It includes the Paleocene, Eocene, and Oligocene epochs.
What period did human ancestors first appear?
Humans first appeared during the Quanternary Period which includes the Pleistocene and Holocene epochs.
What period did human ancestors first appear in?
Humans first appeared during the Quanternary Period which includes the Pleistocene and Holocene epochs.
How many epochs in the Tertiary period?
The Tertiary Period (including the Pliocene, Miocene, Oligocene, Eocene, and Paleocene Epochs) lasted from about 65 million years ago to 1.8 million years ago. It is part of the Cenozoic Era, along with the Quarternary Period.
Is the neogene apart of quaternary?
The Neogene Period is not a part of the Quaternary Period. The Quaternary Period occurred right after the Neogene Period. The Neogene is divided into two, Miocene and the Pliocene epochs.
