Answer: Renewable Resource
Explanation: There isn't a limited supply of water, which makes it a renewable resource.
From the given information, it's not possible to find the mass or the volume of the sample.
Density is their RATIO, but you can't tell if the sample is the size of an ant or a school-bus.
Answer:
They show the elements that make up a compound.
They show the three-dimensional shape of a molecule.
They show the types of atoms that make up a molecule.
They show the number of each type of atom in a molecule.

Answer:
radius of curvature is 1.2 m
Explanation:
given data
distance u = 30 cm
to find out
radius of curvature
solution
we know radius of curvature is double of focal length
so we find focal length
lens formula for focal length
1/f = 1/u + 1/v ..............................1
so here from magnification
M = - u /v
2 = - u /v )
v = -2u = -2(30)
v =- 60 cm
so from equation 1
1/f = 1/u + 1/v
1/f = 1/30 + 1/-60
f = 60.02 cm
so R = 2f
R = 2( 60.02)
R = 120.04 cm
so radius of curvature is 1.2 m
