I believe the question talks about displacement and
distance. The difference of the two is that displacement is the linear distance
or shortest distance drawn from the starting point until the final point while
distance is the whole trip that is covered, so the answer is:
<span>Displacement, distance</span>
Answer:
5.8399
Explanation
work:
176cm
1cm=0.39 in
1cm=0.39x178=178cm=70.07in
70.0787/12=5.8399
Answer:
<h2>
2113 seconds</h2>
Explanation:
The general decay equation is given as , then;
where;
is the fraction of the radioactive substance present = 1/16
is the decay constant
t is the time taken for decay to occur = 8,450s
Before we can find the half life of the material, we need to get the decay constant first.
Substituting the given values into the formula above, we will have;
Half life f the material is expressed as
Hence, the half life of the material is approximately 2113 seconds
