E=F*d/2 = M*g*d/2 = 25kg * 9.8 N/kg *0.65m / 2 = 79.625J
Answer:i don't know sorry good luck tho
Explanation: i have not learned it yet
A sphere is charged with electrons to −9 × 10−6 C. The value given is the total charge of all the electrons present in the sphere. To calculate the number of electrons in the sphere, we divide the the total charge with the charge of one electron.
N = 9 × 10−6 C / 1.6 × 10−19 C
N = 5.6 x 10^13
According to the big bang theory, the universe was once a very C. hot and hostile place, and it expanded rapidly. This rapid expansion was the very reason it eventually cooled down and eventually got to its present state where all the planets and galaxies and what not were created.
