A person eats a dessert that contains 230 Calories. (This "Calorie" unit, with a capital C, is the one used by nutritionists; 1 Calorie = 4186 J. See Section 12.7.) The skin temperature of the person is 36 °C and that of her environment is 18 °C. The emissivity of her skin is 0.84 and its surface area is 1.5 m2. How many hours would it take her to emit a net radiant energy from her body that is equal to the energy contained in this dessert?

Answerwavelength;

The independent variable would be the fertilizer as it is what the dependent variable (the growth of grass) depends on.

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
