Answer:
Force of 540 Kgm/s^2 is closest to the net force acting on the vehicle.
Explanation:
Force is the change in momentum per unit time
This relationship is equivalent to product of mass and acceleration
Thus F = Mass * acceleration
Substituting the given values in above equation we get -
F = 450 Kg * 1.2 m/s^2
F = 540 Kgm/s^2
Cellulose is the primary structural component responsible for much of the mechanical strength of the cell wall.
The structure of cellulose consists of long polymer chains of glucose units connected by a beta acetal linkage
B .The membrane is what separates, and is the system boundary.<span />
Answer: True
Explanation:
Natural selection is a process of emergence of traits in organisms which are useful for their survival and reproduction. These traits are heritable and pass on from the parents to the offsprings. This results in changes occurring in the same species at genetic, physiological and morphological levels. This results in evolution.
