While we think and feel that we are touching, we actually are not(: It’s all an illusion made by the brain
Una reacción química, también llamada cambio químico o fenómeno químico, es todo proceso termodinámico en el cual dos o más especies químicas o sustancias (llamadas reactantes o reactivos), se transforman, cambiando su estructura molecular y sus enlaces, en otras sustancias llamadas productos.
I may be wrong, but i believe it is C, as there is no mention of sunlight being a control variable. the amount of sunlight greatly determines plant growth since they obviously use it for photosynthesis
Explanation :
We know that the slope of velocity -time graph gives the acceleration. Acceleration of an object is defined as the rate of change of velocity i.e.
Suppose a driver suddenly applies brakes. In this case the initial velocity of his or her vehicle is more and the final velocity is less.
So, the acceleration is negative in this case i.e. the object is decelerating.
A negative slope on the velocity versus time graph indicates that an object is not accelerating. This statement is false as the object is decelerating.
