Answer:
196J, but C. at 200 J comes close.
Explanation:
Potential energy due to gravity is given by:
PEgrav = mass • g • height
where g is the acceleration due to gravity. We'll use 9.8 N/kg (on Earth).
PEgrav = mass • g • height
PEgrav = (2 kg) • (9.8 N/kg) • (10 m)
PEgrav = 196 N*m
1 N*m = 1 Joule
PEgrav = 196 J
C. at 200 J comes close. The solution probably used a value of g equal to 10 N/kg)
alignment of the Earth with the Moon and Sun
This is the answer.

Waaaaaaaaaaaaaaaaaaaàqqqqqqqaaaaaaaaaa i need points the answer is...
Answer: element
Explanation:
It only has one type of atom making it a element
50.00ml*(10^-3L/ml)*(3.91moles/L) = 0.196 mol
