100 POINTS!!! ANSWER ASAP [5 SENTENCE ANSWER] Explain the relationship among distance, mass and gravitational force between any
Karolina [17]
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled. If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.

Hope this helps.

what are some advantages and disadvantages of using permanent slides as opposed to temporary slides to view tiny aquatic animals
nikitadnepr [17]

Answer:

Permanent slides ensures preservation of the body parts of the tiny aquatic animals and also also aids good visualization.Most of the exoskeleton of   these tiny   animals are lost during temporary slides preparation, thus loss of visualization.

Because the animals are transfixed to a point, their body parts can not be moved.

It also saves time, energy and resources spent during observation.

However,because of dehydration during preparation  their natural color may be lost which may affect observation of natural features
