Answer:
1. Recollapsing universe
2. Critical universe
3. Coasting universe
Explanation:
Recollapsing universe has dark matter density greater than critical density. While critical universe has its matter density equal to the critical sensity. Coasting universe on the other hand has much smaller matter density compared to critical density.
Note that the critical density is approximately 10^-20 grams/cm3
Well minerals are in the water we drink every Day, even the food we eat. Minerals are contained in rocks so there for both are important to life
-- Well first of all, the waves are <em>transverse waves</em>. The fibers in the rope, and the hand that generates the waves, are moving up and down, but the wave is moving to the right, towards the wall. These directions are perpendicular.
-- Later on, after the waves reflect from the wall and travel back toward the hand, there are going to be <em>standing waves</em> on the rope. But this is probably beyond the scope of the question.
Hello
The jovian density is
, while the density of terrestrial planets is much higher. For instance, the earth's density is
. The reason of this difference is in the different chemical composition: while jupiter is made of gas (mainly hydrogen), with lower density, while the terrestrial planets are made of solid and liquid, with compounds of higher density.
Explanation:
acceleration equation is change in velocity/time
so 100/3 will be 33.3km
