Answer:
time taken for 25% Phlebotinum and 75% Dilithium is 168 million years
Explanation:
radioactive isotope of Phlebotinum decays into Dilithium.
time taken to half life takes = 42 million years
half life means that the Phlebotinum is 50% and Dilithium is also 50%
and now it is given that Phlebotinum is 25% and Dilithium is 75%
hence this condition will come after two half lives.
for one half life it takes 42 million years
and for second half life time becomes 4 times of first half life
time for 25% Phlebotinum and 75% Dilithium is = 4 × 42
= 168 million years.
hence time taken for 25% Phlebotinum and 75% Dilithium is 168 million years
Oh yes, that is so true :)
That would be 75% of Earth's atmosphere.
Hello. This question is incomplete. The full question is:
What can scientists learn from magnetic striping patterns? Select the three correct answers.
1. the cause of magnetic pole reversals
2. the year the next magnetic reversal will take place
3. the location of ancient faults caused by seismic activity
4. the exact location of the next earthquake along the California coast
5. the direction plates are moving relative to each other
6. the speed of one plate as it subducts below another plate
Answer:
The direction plates are moving relative to each other
The speed of one plate as it subducts below another plate
The location of ancient faults caused by seismic activity
Explanation:
Magnetic striping patterns are very valuable systems for understanding the factors that promote polar variability of the ocean floor. This is because these systems are formed exactly by changes in this polarity, presenting lines (similar to a zebra), which allow scientists to interpret them and have valuable information about the movement of the direction plates towards each other, the speed that a plate reaches the subduz below another plate and the location and old faults that were caused by the existence of seismic activities.
The burgess and Hoyt models both try to understand urban land use. Both models have the same assumptions (e.g all land is flat, the importance of centrality, and etc).
