Answer:
2.4 m
Explanation:
We are given that
Maximum moment about A=18 kN m
Force=15 KN
We have to find the largest allowable length of the beam
Let larges length of beam=L
Moment about A
M=
According to question
Hence, the largest length of the beam=2.4 m
Answer:
103.3 %
Explanation:
For a radioactive isotope, the number of radioactive nuclei left (parent nuclei) after a time t, N(t), is
where
N0 is the initial number of radioactive nuclei
t is the time
is the half-life of the isotope
Here we have
So we find
Which means that the fraction of parent nuclei left after this time is 0.508 (50.8% of the initial value). So the fraction of daugther nuclei at this time is
So the percentage of parent to daughter isotopes is
Which corresponds to 103.3 %.
