3D model with dimensions (SE or SW view) and The 3D model's Top view Note : use creo parametric to show the above view

On the part shown, specify a geometric control to make the left surface in the front view perpendicular to the bottom surface within .005 total, and what would the the flatness on the left surface of the part above be? Can a datum or feature modifier be applied to this feature control frame? why or why not?

This problem comes from Introduction to Graphics Communications for Engineers 4th Edition page 64 #8 could you help me sketch the isometric view given the 3 standard views

You are watching a live concert. You can also find the concert streaming live on Spotify. About how far must you stand from the stage in order for the live concert and the live stream to be perfectly in sync? HINT: Assume the radio signal (Spotify) has to travel all the way around the Earth. circumference of the Earth (average): 40,041,000 m Speed of sound: 345 m/s Speed of light: 300,000,000 m/s
