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
Answer:
Yes.
Explanation:
In this region we see that faulting has occurred. Because the rock strata are not lined up with one another across the entire region, it is clear that the land has faulted and the the two edge blocks have slipped downwards leaving the middle block uplifted or that the middle block has been pushed upwards.
These two types of faulting are called normal faulting and reverse faulting. They are the result of tension and compression stresses, respectively, that pull and compress the rocks creating fractures called faults. If the stress is sufficient, the outer blocks slide downward or the middle block is uplifted.
Ben's latest journey will take him from Tokyo to San Francisco, and is set to last for five months. That's 5,500 miles worth of swimming, the first-ever attempt by someone to cross the Pacific in this way. Ben will be swimming eight hours<span> a day at the average speed of two to two and a half knots per hour</span>
Yes, as the earth gets closer it gets warmer and as the sun gets further it gets colder
