I believe the answer would be polygenic. The word translates to "multiple genes". This occurs when many genes make up one specific thing such as our hair color or eye color.

<span>Aristotle would say that an object comes to rest because it got tired. Aristotle came up with ideas, but never tested them.
Galileo used experiments and mathematical models to analyze motion. He used a slanted inclined plane an order to slow down the acceleration due to gravity on an object. He found out that an object accelerates as it falls. </span>
(a) The initial speed at which the bottles are launched is 4.27 m/s.
(b) The horizontal displacement at which the bottle land is 1.75 m.
<h3>Initial speed of the bottle</h3>
The initial speed of the bottle is calculated as follows;

where;
- T is time of flight
- u is the initial speed
2usinθ = Tg
u = Tg/(2sinθ)
u = (0.5 x 9.8)/(2 x sin35)
u = 4.27 m/s
<h3>Horizontal displacement of the bottle</h3>
X = u²sin(2θ)/g
X = (4.27² x sin(70))/(9.8)
X = 1.75 m
