Homework Help Overview

The problem involves calculating the total number of frames needed to show a 2-hour motion picture, given that 24 frames are displayed per second. The height of the film frame is noted as 35 cm, which raises questions about its relevance to the calculation.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the calculation of frames over 2 hours, questioning whether the height of 35 cm is pertinent to the problem. Some express confusion about the dimensions of the film frame and its implications for the total number of frames or the length of film required.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the original question and the significance of the 35 cm measurement. There is no explicit consensus on the interpretation of the problem, and multiple viewpoints are being explored regarding the dimensions of the film.

Contextual Notes

Some participants note that standard motion picture film is typically measured in millimeters, suggesting that the 35 cm figure may be an error or misinterpretation. This raises further questions about the assumptions made in the problem setup.

Homework Statement


The height of motion picture film's frame is 35 cm.If 24 frame go by 1 sec calculate the total number of frames required to show ia 2h long motion picture.

Homework Equations


simple Equation which I don't need to write here I guess

The Attempt at a Solution


The Height of motion picture is 35 cm which is the confusing part for me.1 sec 24 frame goes mean 1 hour 24x3600 frame goes in 2 hour 2x24x3600.Is that true ?? .Is the height in there just a extra ?*

I am not sure you included the full question. The total number of what? 35cm seems quite large for a frame?
You calculated the number of frames in 2 hours. 2*24*3600 frames. Is that what the question is asking for, or is it asking for the length of film on a reel?
 
I wrtie the full question
 
I didnt understand too how can be 35 cm to film frame ?

Most motion pictures were shot on 35 mm film. A few blockbuster films also got copied to 70 mm film, both of which formats are considerably smaller than 35 cm filum.

It would take a crane to lift a can of 35 cm movie filum.
