An object measures 5 cm x 3 cm x 2 cm. what is its volume? what is the density if its mass is 10g?

lets assume

L = length of the object = 5 cm

h = height of the object = 3 cm

w = width of the object = 2 cm

V = Volume of the object

Since the dimensions of object suggest it to be a cuboid

Volume of the object is given as

V = L w h

inserting the values

V = 5 x 3 x 2

V = 30 cm³

m = mass of the object given = 10 g

ρ = density of the object = ?

density of the object is given as

density of object = mass of object / Volume of object

ρ = m/V

inserting the values

ρ = 10/30

ρ = 0.33 g/cm³

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 : ))

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
