Which statement is true because of newtons second law ?a)when the net force on an object increases, the objects acceleration decreases
b)when the net force on an object decreases ,the objects acceleration increases
c)when the net force on an object decreases, the acceleration doesnt change
d)when the net force on an object decreases, the objects acceleration decreases

Answers

Newton's second law, by definition, states that,  The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. Therefore, based on the given options above, the correct answer would be option D: when the net force on an object decreases, the objects acceleration decreases.

d. when the net force on an object decreases, the objects acceleration decreases

Sheela wants to make a computer model of a land ecosystem. Part of her model simulates the chemical processes of photosynthesis that involve the creation of sugars. Which of these chemical processes are these?A. the light-dependent reactions
B. the light-independent reactions
C. the dark reactions
D. the reactions in the mitochondria

Answers

The correct answer is A, the ligt-dependent reactions. These reactions are responsible for the production of glucose molecules, by the utilization of carbon dioxide, and water along with the sunlight. Glucose is then broken down during resiration process, for the production of ATP in mitochondria.

B. the light-independent reaction is the correct answer in Edgen

What is the concentration of a 450 mL solution that contains 200 g of FeCl2?

Answers

Molar mass FeCl₂ = 126.751 g/mol

450 mL / 1000 = 0.45 L

1 mole ------- 126.751 g
? mole ------- 200 g

moles = 200 * 1 / 126.751

moles = 200 / 126.751

= 1.57789 moles FeCl₂

M = n / V

M = 1.57789 / 0.45

= 3.50 Mol/L or M

hope this helps!
