Welcome to APlusPhysics Carolyn!

Welcome Bala!

Hi Terry  based on popular request of instructors I don't give out the solutions to the lab, leaving it to instructors to formulate their solutions (otherwise it becomes a much less effective tool for classroom teachers as students could just copy the answers).

Right, but it's ultimately a proof of 1 vs. 1, not an empirical derivation of g. You're proving something is itself if you use theoretical values.

Graphing the empirical k_delta_x vs. Msintheta would work, but not the theoretical. They want you to determine an empirical value for g, not do a mathematical exercise that results in a 1=1 proof.

See here:

I might start with a resource like this: https://opentextbc.ca/physicstestbook2/chapter/dampedharmonicmotion/ or this: https://www.toppr.com/guides/physics/oscillations/dampedsimpleharmonicmotion/

Hi Muskkan. Damped oscillators are outside the scope of AP Physics 1/2, but happy to help if I can. How far have you gotten so far / where are you getting stuck?

The one about the ice skater? Can you be more specific?

Absolutely... want you to be 100% satisfied with your purchase. Refund complete.

Correct. When you purchase the book it specifically says it cannot be printed (part of the licensing deal with publishers). However, all of the question sets are available to print individually at https://www.aplusphysics.com/courses/regents/worksheets/ws_index.html.

Hi ertugrultiyek. Sounds like a solid question. What have you tried so far?

Hi Myua,
It's in the download section  the previous "buy" button turns to a "download" button after you complete the purchase. To save you the trouble, however, I also emailed you the file.

Connecting to ground provides an infinite supply of electrons (or can be an infinite sink of electrons). If you ground a metal rod, and hold a negative rod near an end, negative charges will be repelled from the rod into the ground. If you then disconnect the rod from the ground, no charges can enter or leave the rod, so you're left with a net positive charge on the rod.

Page 78 in the book talks about charging by induction. This section should help you out. It doesn't matter which part of the metal rod is grounded, since it's a conductor.

All the best to you and yours as well! Merry Christmas!

I would think the final pressure would be atmospheric... 🙂

Hi Robin, and welcome! Your book is available in the Community > Downloads section (from the same page where you purchase), but I've also emailed a copy to you for convenience. Thanks for the support!

I don't think anyone has ever gotten this far before. Kudos, WUV Our Work!!! 😎

Fantastic Kerbal season!

Terrestrial exploration accomplished!

A fantastic Kerbal season!

A penny saved is a penny earned!

That is quite the find! Very cool... well done!
Kinematic magnitude of acceleration

Use your kinematic equations. Start by writing what you know (initial velocity is 0, time is 0.3 seconds, and distance traveled can be measured from the drawing).
Once you know three things, you can use your kinematic equations to solve for the other two (details here: https://www.aplusphysics.com/courses/regents/videos/KinEqns_Reg/KinEqns_Reg.html)
