What is the density of an object having a mass of 0.8g and a volume of 25cm?

Not enough information. To get the density, you need to divide the mass by the volume, but there is no way of knowing the volume of an object just by having one of its lengths.


What is normal eye not able to see clealy the object placed closer then 25cm?

An eye works by taking the light that is coming from a point on an object and bending it so that it is all focused on single point at the back of the eye. The lens of the eye can only bend the light so much and the closer the object is the more the eye has to bend the light. If the object is closer than 25 cm it can't bend it enough.


How large the image will be if the object is 25cm tall?

The size of the image will depend on the distance between the object and the lens (or mirror) producing the image. If you provide information about this distance, we can help calculate the size of the image.


What is a zero object?

In category theory, a zero object is an object that is both initial (there is a unique morphism from the zero object to any other object) and terminal (there is a unique morphism from any other object to the zero object) in a given category. It serves as a generalization of the concept of the zero element in algebraic structures.


Object a and object have the same kinetic energy but object b is moving faster what can you infer about object a?

Object a likely has a greater mass than object b since they have the same kinetic energy but object b is moving faster. This suggests that object a has more inertia compared to object b.
