Gold, quartz, and talc are minerals. Copper and iron are types of ore. What is the difference between minerals and ores?

A mineral is a non-living, solid substance that can be extracted from the ground. Ore is a type of mineral made up of metals.

An ore is non-living and solid with little value unless it occurs in large amounts, in which case it is a mineral.

O A mineral is a valuable form of ore that can be extracted from the ground

O A mineral is a non-living, solid substance made of elements. Ore is a large deposit of one or more valuable minerals in the ground.

Unpolarized light whose intensity is 1.19 w/ is incident on a polarizer. (a) what is the intensity of the light leaving the polarizer? (b) if the analyzer is set at an angle of = 41.0∘ with respect to the polarizer, what is the intensity of the light that reaches the photocell?

Which form of cell division creates the sperm and egg, resulting in half of the chromosomes as the other cells?

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
