Answer:
Yes
Explanation:
There is a position that works better than this and that is switching the sides of the forks.
<span>Cobalt-60 is undergoing a radioactivity decay.
The formula of the decay is n=N(1/2)</span>∧(T/t).
<span>Where N </span>⇒ original mass of cobalt
<span> n </span>⇒ remaining mass of cobalt after 3 years
T ⇒ decaying period
t ⇒ half-life of cobalt.
So,
0.675 = 1 × 0.5∧(3/t)
log 0.675 = log 0.5∧(3/t)
3/t = log 0.675 ÷log 0.5
3/t= 0.567
t = 3÷0.567
= 5.290626524
the half-life of Cobalt-60 is 5.29 years.

Answer:
23932242.5 Pa
Explanation:
= Atmospheric pressure = 
= Pressure of seawater
= Density of sea water = 
h = Depth of shipwreck = 
g = Acceleration due to gravity = 9.81 m/s²
The absolute pressure is given by
The absolute pressure at the depth of the shipwreck is 23932242.5 Pa
Answer:
