It is given that the height of the tower is
The uncertainty the measurement of this height is
Drop time is measured as:
The uncertainty in measurement of time is:
Using the equation of motion: 
where, 
is the distance covered, 
is the initial velocity, 
is the acceleration and 
is the time.
(because canon ball is in free fall). we need to calculate the value of a=g.
The uncertainty in this value is given by:
Substitute the values:
The study of cosmos is of the large scale structures & evolution of the universe, it encompasses the origin, evolution, composition, and the eventual face of the universe.
Answer:
149.96J
Explanation:
Given parameters:
Number of stairs = 33
Height = 0.25m
Weight = 599.85N
Unknown:
Energy the person takes to reach the top = ?
Solution:
To solve this problem;
The energy it takes is given as:
Energy = weight x height
Energy = mass x gravity x height
Now,
Insert the given parameters and solve;
Energy = 599.85 x 0.25 = 149.96J
Answer:
Yes. Yes, you can.
Explanation:
Combinations of increased pressure and decreased temperature force gases into containers that we use every day. You might have compressed air in a spray bottle or feel the carbon dioxide rush out of a can of soda. Those are both examples of gas forced into a smaller space at a greater pressure.
Hope this helps :)
It means his paper plane has gravity
