W=Fd. Force is not given so we solve for it. F=ma, m=5kg, a=2m/s^2, F=10N. Distance is not given so we solve for it, x=.5a(t^2)=.5(2)(7x7)=49m. F=10N, d=49m, W=490J.
Answer:
the activity of thallium is 1.54 kBq .
Explanation:
given,
half life = 3.7 years
R₀ = 10 kBq
time = 10 years
R = 10 × (0.153667)
R = 1.5367 ≈ 1.54 kBq
hence, the activity of thallium is 1.54 kBq .
weather is everyday things
weather could be a hurricane
weather could be a tornado
climate is more long term over time
example the climate in Antarctica is cold because it happens over long periods overtime
