Would it be a

a physical model
b a computer model
c a real world model
d a life size model

It would depend on the context and the specific purpose of the model.

a) A physical model refers to a physical representation of an object or system, typically created using materials like clay, wood, or 3D printing.

b) A computer model, on the other hand, is a digital representation of an object or system created using computer software.

c) A real world model can refer to an actual object or system that exists in the real world, which can be observed and studied directly.

d) A life size model usually refers to a physical model that is constructed to scale and matches the exact size of the original object or system in the real world.

Overall, the choice between a physical, computer, real world, or life size model depends on the purpose, feasibility, and specific requirements of the modeling task.

The question is a scientist visits the planetarium the scientists views and exhibit on stores which was made using lights and computer program how would this store exhibit be classified

a a physical model
b a computer model
c a real world model
d A life-size model

Based on the information provided, the store exhibit at the planetarium would be classified as:

b) a computer model.

This is because the exhibit was made using lights and a computer program, indicating a digital representation rather than a physical or real-world model.
