Pretty sure it’s false....................
The statement that is a quantitative observation is that bird has four different colors on it (option B).
<h3>What is a quantitative research?</h3>
A quantitative research is a systematic scientific investigation of quantitative properties and phenomena and their relationships, using statistical methods.
A quantitative observation has to do with numbers or numeric analysis.
This suggests that the statement that is a quantitative observation is that bird has four different colors on it.

Th answer is it could gain or loss magnetism.
Ferromagnetism is a kind of magnetism that is associated with cobalt, iron, and nickel and on some alloys or compounds containing one or more of the said elements, It also occurs in gadolinium, which is a rare-earth element. In comparison to other substances, ferromagnetic materials can be magnetized easily and in strong magnetic fields, the magnetization approaches a definite limit called stauration.
If an external field is applied and subsequently removed which does not return the magnetization to its original state or value it is called hysteresis. When heated to a certain temperature (Curie point), which is unique for each substance, ferromagnetic materials would somehow lose their magnetic properties and cease to be magnetic. Once they would cool down, their magnetism would return.
Answer:
Explanation:
We will use the formula for accelerated motion 
, which for acceleration it means:
<em>In our case</em> our initial velocity is 
and our final velocity is 
since it comes to rest, this process while traveling a distance 
, so we have:
Which in absolute value means a deceleration of
Answer:
<em>The Strength of the electric field produced = 2 × 10⁷ N/C</em>
Explanation:
<em>Electric Field:</em> This is defined as the region where an electric force is experienced.
<em>Electric Field Strength: </em><em>The intensity of an electric field at any point is defined as the force per unit charge which it exert at that point. It direction is that of the force exerted on a positive charge.</em>
<em>It is represented mathematically as,</em>
<em>E = F/Q ................................. Equation 1</em>
<em>Where E = Electric field strength, F = electric force, Q = test charge.</em>
<em>Given: F = 3.2 × 10⁻⁴ N, Q = 1.6 × 10⁻¹¹ C</em>
<em>Substituting these values into equation 1</em>
<em>E= 3.2 × 10⁻⁴/1.6 × 10⁻¹¹ </em>
<em>E= 2 × 10⁷ N/C</em>
<em>Thus the Strength of the electric field produced = 2 × 10⁷ N/C</em>
