Answer: He found a rock, and the crystals inside are minerals.

Options:

  • He found a rock, and the crystals inside are minerals.
  • He found a mineral, and the crystals inside are rocks.
  • He found a rock, and the crystals inside are rocks, too.
  • He found a mineral, and the crystals inside are made of dirt.

Explanation:

A rock differs from a mineral. While they are both solid, a mineral has a crystalline structure while a rock does not have a specific structure. Rocks are made up of different mineral structures and that is what Joseph discovered on dropping the rock, one of the component minerals in the rock. For example, a type of rock, slate may consist of feldspar, quartz among many other minerals.

Answer:

at 4 p.m Baghdad located at 45°E

at 8p.m Indonesia is located at x°

we have

common difference in time =8p.m-4p.m=4hours =4×60min

again

we have

4min=1°

4×60min=4×60/4=60°

since time is in p.m on both so they lie in same direction

Therefore, longitude of Indonesia=60°E.

hope this helps you. thanks
