Free insulative sheets and insulative sheets backed by a grounded conductor are the only cases in which it is possible to extract reliable information from a noncontacting measurement of the charged state of an insulator. In both cases, the electric field from the charge is the deciding factor.<span>

Bird bones have air pockets in them to reduce their weight–this also gives them an average density significantly less than that
Ksenya-84 [330]

Answer:

39.4 g

39.4 cm³

1.09137 g/cm³

Explanation:

\rho = Density of water = 1 g/cm³

Mass of water displaced will be the difference of the

m=43-3.6\\\Rightarrow m=39.4\ g

Mass of water displaced is 39.4 g

Density is given by

\rho=\dfrac{m}{v}\\\Rightarrow v=\dfrac{m}{\rho}\\\Rightarrow v=\dfrac{39.4}{1}\\\Rightarrow v=39.4\ cm^3

So, volume of bone is 39.4 cm³

Average density of the bird is given by

\rho=\dfrac{43}{39.4}\\\Rightarrow \rho=1.09137\ g/cm^3

The average density is 1.09137 g/cm³

QUESTION 3Plasticity refers to the:A.fact that many academic fields contribute data to the science of development.B.ability of h
Solnce55 [7]

Answer:

B.ability of human traits to be molded during development.

Explanation:

Plasticity:

 1.When pressure is applied then some deformation occurs and to retain this deformation is known as plasticity.

2. It is the capacity of molding

Plasticity refers to the ability of human traits to be molded during development.

So the option B is correct.

B.ability of human traits to be molded during development.

When is zero considered significant​
vazorg [7]

If a zero is found between significant digits, it is significant. Zeros can be used as (insignificant) place holders to the left of significant digits if the number is a decimal. For example, a mass of 42 g has two significant digits. Expressed in kilograms, the mass of 0.042kg should still have two significant digits.
