Answer:

I = \frac{1}{12}m_t(2x)^2+m_1x^2+m_2x^2

Explanation:

The moment of inertia for the beam is:

I = \frac{1}{12}m_tL^2

Where m_t is the mass of the beam and L is the lengh of the beam

note:

L = 2x

And for particles I is equal to:

I = MR^2

where M is the mass of the particle and R is the distance between the pivot and the particle.

Finally, the moment of inertia for this assembly is the sum of the moment of inertia of the particles and the beam. So:

I = \frac{1}{12}m_t(2x)^2+m_1x^2+m_2x^2

as the trait is dominant and controlled by a single gene,the mutation must have occurred on both diploid copies. true or false?
GenaCL600 [577]

Answer:

False

Explanation:

A dominant trait is a trait that is inherited from parents. It is a trait that is obtained from a particular copy or type of a gene that overshadows or overwhelms the effects of another type or copy of that gene. Dominant traits are controlled by a single gene.

Therefore , as the trait is dominant and controlled by a single gene,the mutation must have occurred on both diploid copies is a false statement.
