Which statement is true about the gravitational force? a. it only acts on objects that are close to each other. b. it acts on all objects all of the time. c. it only acts on objects that are in contact. d. it only acts on objects that are moving apart.

B. It acts on all objects all of the time.  

Explanation:

Gravitational force is a kind of force that act on all object . The gravitational force can be defined as the force that attract two object with mass. The gravitational force is all around us . it is what determines how far a thrown object is before it reaches the surface. The gravitational force determines how much we weigh. The gravitational force is the force the earth exerted on you.

Newton Law of gravitation explain gravitational force and can be stated as follows. Every masses of object attracts each other with a force which is directly proportional  to the product of their masses and inversely proportional to the square of the distance between them.  

G = m1 m2/ r²  

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
