Answer:
19,600 Nm
Step-by-step explanation:
WD = mgh
= 40 × 9.8 × 50
= 19600 Nm
Given:
Initial mass, m₀ = 23 g
Decay constant, k = 0.13
Exponential decay obeys the equation

where t = time, days
For half life, the mass is m = m₀/2.
Therefore

Answer: The half life is 5.33 days
I got that question and the answer C
