Answer:
Gravitational potential energy,
Explanation:
Mass of an Egyptian pyramid,
It is placed 19 m above the surrounding ground, h = 19 m
We need to find the gravitational potential energy store in the pyramid. This energy is possessed by an object due to its position. It is given by :
So, the gravitational potential energy store in the pyramid is . Hence, this is the required solution.
True. The speed of any object will have faster acceleration, and eventually slow down due to gravity.
Answer:
-3.4 eV ()
Explanation:
In a hydrogen atom, the energy of an electron is given by:
where
n is the principal quantum number
For an electron in the 2s orbital,
n = 2
So substituting this value into the formula, we find
And converting this into Joules, we have
Answer:
0.00025 kilometers
Explanation:
divide the length value by 1e+6
A. the carbons are unbalanced
B. the hydrogens are unbalanced.
D. the chlorines are unbalanced.
That leaves C. to be correctly balanced.
