The element is iridium and it has 77 electrons
It will sink because mass does not affect the physical properties of the object.
Answer:
Explanation:
From, the given information: we are not given any value for the mass, the proportionality constant and the distance
Assuming that:
the mass = 5 kg and the proportionality constant = 50 kg
the distance of the mass above the ground x(t) = 1000 m
Let's recall that:

Similarly, The equation of mption:

replacing our assumed values:
where 



So, when the object hits the ground when x(t) = 1000
Then from above derived equation:


By diregarding 

1000 + 0.981 = 0.981 t
1000.981 = 0.981 t
t = 1000.981/0.981
t = 1020.36 sec
