Physics

General Instructions Provide suitable responses for the problems shown below. The assignment is to be completed individually and returned by 11:30 pm EST on Monday, September 20, 2021. Where applicable, show your work to receive full credit. Late assignments will be assessed a penalty of 10 % of the overall grade per day late. How to Return This Assignment You may upload the document to the drop box in Canvas as a Word file, a pdf file, a jpeg file, a scanned file, etc. The document may also be returned as an email attachment in canvas. If the file is too large, try compressing it using free services such as wecompress.com. Do not return the file using our outlook email. For those who save each page of the assignment as a pdf or image file, you may combine them into one document as follows: • Locate the files in Windows File Explorer. • Right click on the first file. • Choose “Combine Supported Files in Acrobat…” A new dialog box will pop up, but you may have to minimize other files to see it. • Drag the files from Explorer into this box. • If necessary, change the order of the files using “Move Up” or “Move Down.” • Click on “Combine Files.” You will be prompted for a file name. If applicable, you may also copy and paste images in a Word document, and then save the document as a pdf file. Instructions for writing or type on a pdf document will be sent to you as a separate document. Please ensure that your work is legible and your file is complete before and after sending.
