The atomic mass. By taking two different types of the same element and calculating the average based on the amount of each type in the world, you get the basic atomic difference.
The height isn’t a factor.
The gravitational force is the same no matter the height...
So W=mg
20 x 9.81 = 196.2 N
Answer:
t=13000 or t= 1.3x10^4 (ten to the power of four)
Explanation:
d= 650m v=0.05 t=? v= d/t t= d/v 650m/0.05m/s= 13000 if you need to simplify it into scientific notation, move the decimal up, you need to move it up four times, so t= 1.3x10^4s
