Explanation:
To find the half-lifes of the isotope we need to use the following equation:
(1)
<em>where Nt: is the amount of the isotope that has not yet decayed after a time t, N₀: is the initial amount of the isotope, t: is the time and </em><em>: is the half-lifes.</em>
By solving equation (1) for t we have:
<u>Having that:</u>
Nt = 450
N₀ = 3150 + 450 = 3600,
The half-lifes of the isotope is:
Therefore, 3 half-lives of the isotope passed since the rock was formed.

Answer:
Explanation:
Given
Minute hand length =16 cm
Time at a quarter after the hour to half past i.e. 1 hr 45 min
Angle covered by minute hand in 1 hr is 360 and in 45 minutes 270
(c)For the next half hour
Effectively it has covered 2 revolution and a quarter
angle turned
(f)Hour after that
After an hour it again comes back to its original position thus displacement is same =25.136
Angle turned will also be same i.e.
