Fog, mist, dark
No, you cannot.
The distance of the object from the mirror line should equal the distance of the image from the mirror line.
apparent diameter
no, you need to know its initial velocity to determine this; if initial velocity is zero then distance is 1/2 acceleration x time squared
Only if you know your location (the coordinate on the distance scale and the time scale) where "you" are can you infer if the object is moving towards you (the absolute distance to the object is decreasing) or away from you (the distance is increasing).
Real.
If you can't see through an object clearly it is an opaque object.
its magnitude is greater thatn the distance travelled by the object
No, you cannot.
When a force (no matter how large it may be) is applied to any object without a distance being moved,it cannot be workdone because,workdone = force x distance.
c virtual,upright,and larger than the object.

The mass and distance of an object fom another object
To know the speed of an object we need to know the distance the object travels and the time it takes. The object's mass is not needed. Since we do no know the distance in this case, we cannot solve to find its speed.
The mass of the first object; the mass of the second object; the distance between them.The mass of the first object; the mass of the second object; the distance between them.The mass of the first object; the mass of the second object; the distance between them.The mass of the first object; the mass of the second object; the distance between them.
Yes. An isolated mass (one without any other masses near it, where "near" is defined generously) has no discernible weight, and an object in freefall has mass but no weight.Yes. An object in free fall, for example, has mass but no weight.
You cannot because you do not know how long before the object falls to the ground and so stops moving.
