Answer:
The mass of the rule is 56.41 g
Explanation:
Given;
mass of the object suspended at zero mark, m₁ = 200 g
pivot of the uniform meter rule = 22 cm
Total length of meter rule = 100 cm
0 22cm 100cm
-------------------------Δ------------------------------------
↓ ↓
200g m₂
Apply principle of moment
(200 g)(22 cm - 0) = m₂(100 cm - 22 cm)
(200 g)(22 cm) = m₂(78 cm)
m₂ = (200 g)(22 cm) / (78 cm)
m₂ = 56.41 g
Therefore, the mass of the rule is 56.41 g
The electric potential energy is
Explanation:
The electric potential energy stored in a capacitor is given by the equation
where
Q is the charge stored in the capacitor
is the potential difference between the plates
For the capacitor in this problem, we have
is the charge
is the potential difference
Substituting, we find the potential energy:

Genotype
The genotype<span> is the set of genes in our DNA which is responsible for a particular trait. The </span>phenotype<span> is the physical expression, or characteristics, of that trait. For example, two organisms that have even the minutest difference in their genes are said to have different genotypes. </span><span>
