How many nails are in a 3.00 lb container if one dozen nails have a mass of 0.225 lb? view available hint(s) how many nails are in a 3.00 lb container if one dozen nails have a mass of 0.225 lb? 36 nails 160 nails i would add a decimal after the number(160.) to show three sigfigs. 13.3 (or 13) nails 53.3 (or 53) nails

160 nails

Explanation:

from the question we are given the following

mass of container and nails = 3.0 lb

mass of a dozen nails = 0.225 lb

number of nails = ?

we first have to find how many dozen of nails are in the container.

number of dozen = mass of container and nails / mass of a dozen nails

number of dozen = 3 / 0.225

number of dozen = 13.33 dozens

now since 12 nails make a dozen nails, we just have to multiply 13.33 by 12

number of nails = 13.33 x 12 = 160 nails

write a paragraph or story to explain the transformation between potential and kinetic energy as shown in your picture or model.  

you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
