In my physics class, we are going over the Doppler Effect. We were given four different equations for two different scenarios:
- When the observer is stationary but the source is moving
- When the observer is moving but the source is stationary
I was given a problem where both the observer AND the source are moving at some velocity. The source is emitting a given frequency while traveling at a given velocity. The observer is OBSERVING that frequency at a given frequency provided in the problem, but their velocity is unknown. Seeing as the source is traveling at a CONSTANT velocity, can I treat it as though the source, relative to the observer, is stationary, and it is only the observer that is moving? I was thinking of using the receding observer equation of: f- = (1 - v0/v)*fs , where v0 is the speed of the observer and v is the velocity of sound in air, 343 m/s. Would this be correct? Or can I not treat the source as stationary even though it is moving at a constant velocity?
Thank you in advance! Please comment if you need clarification.

My physics class is working on Ohm's law and we did a lab about
series and parallel circuits. While doing the lab report I got
stuck on this question below. Please help!

account for sources of errors."

In my Accounting class we are being asked to respond to/comment
on different things that students post. My professor is requiring a
"substantive" response with references to back up what is being
said. I need some help with a responses to these posts. Any help
you can give me will be GREATLY appreciated! I am WAY out of my
knowledge base in this class.

We started creating a Java class for Car. In this lab we are
going to complete it in the following steps:
1- First create the Car class with some required instance
variables, such make, model, year, price, speed,
maxSpeed, isOn, isMoving, and any other properties you like to
add.
2- Provide couple of constructors for initializing different set of
important properties, such as make,
model, year, and price. Make sure that you do not repeat
initialization of instance variables in...

I have to do an experiment/ demonstration for my PHY251 class
(Calculus based physics). I am only allowed to do it on one of the
following topics: Vectors, Accelerated motion, Centripetal force,
Free fall, projectile motion, Inertia, Equilibrium, Friction,
Orbits, Tides. Does anyone have any ideas for a cool demonstration?
Please provide instructions for the demonstration/experiment. Thank
you in advance.

This probability question from my physics class is confusing me,
any explanation really appreciated!
An analogy: a child with blocks and constraints on
physical systems. A certain child's room is partitioned into 100
squares. His toy box in the corner is exactly one square in size
and contains some number of blocks. When he plays with the toys, he
tends to throw them around and evenly scatter them about the
room.
a) Assume that there are now three blocks (red,...
