Answer:
When standard time is being observed in Los Angeles, the boxing match held at 8 pm local time in Los Angeles it will be on at 5 am the following day in Nigeria.
Explanation:
The time difference between Nigeria and Los Angeles is 9 hours during standard time periods. Nigeria does not observe daylight savings time but Los Angeles and the state of California does, so between March 8th and November 1st, 2020 (the period for daylight savings time this year), the time difference will be 8 hours between Los Angeles and Nigeria. Therefore, during daylight savings time in Los Angeles, the match would be on at 4 am the next day in Nigeria and that is when those wanting to watch the match should turn their TVs on.
Explanation:
A) How much of the parent (X) and how much of the daughter (Y) were present at the time the rock formed? Choose one of the following and explain why
Answer : C) X = 100 % ; Y = 0 %
At the time when the rock was formed, we would have 100% of the parent and 0% of the daughter.
When a radioactive element in rock initially crystallizes, we will only have the parent isotope inside with no trace of the daughter isotope.
A radioactive material is one that spontaneously disintegrates. It produces the daughter stable isotopes as it emits radiations in the process.
The daughter isotope is the stable form of the parent. So when a rock forms, the daughter would not have been produced.
B) X = 50 % ; Y = 50 %
After the time 5730yrs has elapsed, we are going to have both daughter and parent in the ratio 50% to 50%.
The half-life is the time taken for half of a radioactive isotope to decay to half of its original component.
When a radioactive element is decomposing, it will produce daughter isotopes.
At the half-life time, the parent would have disintegrated by half and produced half of the daughter.
