For each of the following vector fields F , decide whether it is conservative or not by computing the appropriate first order partial derivatives. Type in a potential function f (that is, ∇f=F) with f(0,0)=0. If it is not conservative, type N. A. F(x, y)=(4x−5y)i+(−5x+14y)j f(x, y)= -10x^2-35y^2+53xy B. F(x, y)=2yi+3xj f(x, y)= n C. F(x, y)=(2siny)i+(−10y+2xcosy)j f(x, y)= Note: Your answers should be either expressions of x and y (e. g. "3xy + 2y"), or the letter "N"

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
