Answer;
-Physical model
A physical representation of a real object, such as a globe of the world, is a physical model.
Explanation;
-A physical model is a simplified material representation, usually on a reduced scale, of an object or phenomenon that needs to investigated.
-The model can be used to simulate the physical conditions involved (temperature, waves, speed etc.) and to predict the particular constraints of the situation.
By copying their genomes, they retain the tool kit and at the same time generate a garage full of spare parts. Gene duplication can provide the raw material for expression changes to occur, and polyploidy itself can trigger epigenetic changes
Answer:
(C) Decreases by factor of 3
Explanation:
Centripetal acceleration is given by
where <em>v</em> is the linear velocity and <em>r</em> is the radius of the curve.
Let the centripetal acceleration on the curve of radius <em>R</em> be 
.
Then
Let the centripetal acceleration on the curve of radius 3<em>R</em> be 
.
Then
Here, we see that the acceleration decreases by a factor of 3.
<span>y=x-50
where y is the reading test score and and x is iq score.
This can be found intuitively. Since each point in IQ should increase the score by one point, we know the slope should be 1. Then we use the fact that reading test score is just iq shifted down by 50. This leads to the subtraction of 50.</span>
