Develop a demonstration to show how mass is not the same thing as weight
pychu [463]

This is more of a physics explanation, but here we go.

Mass is a measure of how much "matter" is in an object. Weight is the force applied onto an object by gravity. Weight itself can be related to mass like this:

f_g = mg

where g is a gravitational constant. For our purposes, it's defined by whatever planet you are on. Following this, we can demonstrate that mass is NOT the same thing as weight if we take two objects of the same mass and put them on different planets.

Let E refer to Earth and F refer to Mars

g_E = 9.81 m/s^2\\g_F = 3.711 m/s^2

Following this, we can see clearly that weight is not the same as mass:

m*9.81 : m*3.711 \\\int\limits^a_b {x} \, dx 9.81 \neq 3.711\\f_g E \neq f_g F\\

If weight was the same thing as mass, the two values would be the same, as the mass of the two objects is the same. But since weight is defined in the context of gravity, they are not.

Give two examples of how our society uses isotopes
nalin [4]

Answer:

Isotopes – caused by varying numbers of neutrons in an element – have many practical uses in our society. ... In geology and archaeology, radioactive isotopes are used to determine the age of a sample while hydrologists can use isotope signatures to distinguish between different groundwater types.

Explanation:

Google. It's a magical place.

Metallic barium crystallizes in a body-centered cubic lattice, with one Ba atom per lattice point. If the metallic radius of Ba
Tema [17]

Answer:

1.26 x 10⁸pm³ and 1.26 x 10⁻²²cm³

Explanation: Calculating for a body centered cubic lattice, the formula is

3d²= 16r²

where d =  edge length of unit cell

r=radius of atom

3d²= 16 x (217)²

3d²=753424

d²=251141.3

d= 501.1pm

volume of unit cell= d³= (501.1)³= 1.26 x 10⁸pm³

converting to cm³= 1.26 x 10⁸(10⁻¹²m)³

=1.26 x 10⁸(10⁻¹⁰cm)³ = 1.26 x 10⁻²²cm³
