Answer:
The term "pseudo-science" assumes a criterion that allows a differentiation between science and nonscience, good science and bad science, true and false. ... They must try to understand them and not put out in television programmes the sort of pseudo-science that does not exist in reality
Explanation:
Cruising at 35,000 feet in an airliner, straight toward the east,
at 500 miles per hour.
Since your speed is not changing and you're moving in a straight line,
your acceleration is zero.
Answer:
Explanation:
1. Calculate the decay constant
The integrated rate law for radioactive decay is 1
where
A₀ and A_t are the counts at t = 0 and t
k is the radioactive decay constant
2. Calculate the half-life
The half-life for decay is 
.
The average molecular weight of the mixture can be calculated using this formula:
MWav = x1MW1 + x2MW2
Where x is the mass fraction of the components of the mixture, in this case, copper (63.546 g/mol) and zinc (<span>65.38 g/mol).
</span>
x1 = 7.36 / (7.36+0.51)=0.935
x2 = 0.51 / (7.36+0.51)=0.065
So,
MWav = 0.935(63.546) + 0.065(65.38) = 63.665 g/mol
