hylics BTFO!

Might any kind soul out there be willing to help me write some code in either Python or R?
Everything I've found so far online about Time Series is always about FORECASTING, yet I'm just here trying to compare what's already happened.

I'm looking at the "audio features" of Spotify's Top 200 from 2018 until late 2021.
My two objectives are:
1) How to assess whether # of Covid cases/deaths had/has any significant effect on the daily averages for each country's features?
2) How to check if the average audio scores are different now/"post"-Covid than they were in the ~2 control years before it?

Here's a sample of the data for anyone willing to take a crack at it –

{There I've aggregated the Top200 of each country/day into 1 row of its averages, and the numbered columns like C1, C2, E1, etc. (the ones without the descriptors in the title) I was planning on having be dummy variables to do some regression or something}

Thank you greatly, everyone. I hope you stay well!

How would one condense acetic acid? Neither molecule loses an H20, but from the reaction an H20 (and acetic anhydride) is produced, so i guess you could call that dehydration. I've heard that P2O5 can be used for this purpose. Any other ways to achieve this easily and cheaply?

What are the most /sci/ approved TV programs?

Can /sci/ help an absolute brainlet with figuring out how to go from line 2 to line 3 here? Not homework but a chapter in a book I need for pleb tier econ class.

Kinetic energy is 0.5 mv^2. Then let's say v = c, the speed of light. This means that if a one kilogram object moves at the speed of light, it has 44,937,759 Gigajoules of energy.

What if you theoretically had that much energy and you used it all to accelerate an object which weighs one kilogram. Wouldn't it then move at the speed of light of faster?

do you look like a scientist?

Short version
>Democrats gut a NASA bill to try and bypass congressional rules and backdoor in a voting regulation bill being filibustered in the Senate.

Long version:
>In recent years NASA has been leasing some of its underutilized facilities to other government agencies and educational institutions (old administrative spaces, empty hangers and warehouses, outdated lab spaces, etc.), as a way of maintaining disused assets while at the same time reducing overhead. It's been moderately successful so far - they're averaging an annual revenue of $11 million leasing several dozen sites and using that revenue to fund upgrades and maintenance of the facilities that are actually in-use. They've started doing this with a lot of government assets over the last decade to cut operating costs.

>The law governing NASA's ability to lease these properties expired late last year and there has been an effort in Congress to renew it. A bill passed the House and Senate space subcommittees (there were a few amendments, the debate seemed to be largely over whether to grant a short extension until something more long-term could be written or to just extend the existing guidelines for several years). However in-between being approved by the Senate subcommittee and being voted on by the House, Democrats decided to completely gut all language related to NASA or the space program out of the bill and replace it with a duplicate of the voting regulations bill currently being filibustered in the Senate. The amended bill narrowly passed along party lines - Reps fuming that the Dems gutted a bipartison bill with unanimous support to try and bypass the rules and backdoor in a law that was already submitted and blocked, Dems saying it's a small price to pay for 'saving democracy'.
