Answer:
Object C
Explanation:
Object A has two arrows, one pointing up and one pointing down. Since both arrows are the same length, the forces cancel, and Object A will not move.
Object B also has two arrows, one pointing up and one pointing down. However, the downwards pointing arrow is much longer than the other. This means it has more force and the object will move down.
Object C has two arrows, one pointing up and the other down. However, the upwards pointing arrow is longer than the other, meaning it has more force and the object will move upward.
Object D has two arrows, but both are pointing downwards, meaning the object will move down.

The answer is; Oil shale occurs only in areas with plentiful water resources for processing.
The refinement of oil shale requires a lot of water. This is used to quench the products of retorting and pyrolysis and also reduce dust. The water used becomes heavily polluted and has to be treated before discharge, otherwise, it will be the cause of a major environmental disaster to the local areas.
Answer:
(B.) their predictions are almost never accurate
Explanation:
A model is a representation of an idea, process that scientists use in explaining a complex data to a more simple and understable way. Models reflect the natural world e.g. climate models are used by humans to learn and to know about carbon cycles, water cycles and the weather. Model do come with some limitations one of them is an incomplete detail e.g. measuring the distance round the earth, we were made to believe that the model of the Earth is spherical, so in calculating the distance round the earth certain details are missing like the variations in distance caused by valleys and mountains and other topological problems that might be encountered.
