Answer:
See explanation below.
Explanation:
Given two blocks of masses M and m, And a force F acting on the block of mass M pulling it outside.
The two masses system can be considered as a whole, With F being the only external force acting on them.
Here the spring force has been ignored as while considering the two system as a whole, it will be accounted as an internal force for the system
Therefore, The acceleration of the system will be:
Now both the masses are moving with this same acceleration towards the direction of force .
Acceleration of mass m = a (as the system is moving as a whole)
Force on the mass m= mass times acceleration.

Given parameters:
Decay constant = 13.6 x 10⁻¹²/s
Unknown:
Half life of the element = ?
Solution:
From the decay constant, we can find the half-life of this radioactive element.
Half-life =
Half-life = = 5.1 x 10¹⁰s
Answer:
1.41 m/s, 7.85 rad/s
Explanation:
We can start by calculating the tangential velocity, which is given by:
where
r = 18 cm = 0.18 m is the radius of the circumference
T = 0.8 s is the period
Substituting,
Now we can also calculate the angular velocity, which is given by:
where again,
T = 0.8 s is the period
Substituting,
