Answer:
λ = 0.03 s⁻¹
Explanation:
The formula for decay constant can be used as follows:
where,
= ratio of remaining nuclei to the initial value of nuclei = = 0.167
t = time = 60 s
λ = decay constant = ?
Therefore,
<u>λ = 0.03 s⁻¹</u>

Answer:
The mass of the planet Newtonia is .
Explanation:
It is given that,
Mass of the bob, m = 1.25 kg
Length of the simple pendulum, l = 185 cm = 1.85 m
Time taken by the simple pendulum, T = 1.42 s
The circumference of Newtonia is measured to be 51,4000 km. The time period of the simple pendulum is given by the formula as:
g is the acceleration due to gravity on planet Newtonia
For one complete cycle, T = 2.84 s
The formula of acceleration due to gravity on any surface is given by :
Since,
So, the mass of the planet Newtonia is . Hence, this is the required solution.
