ah hah.
Suppose my problem looks like this, then:
A 3 kilogram rabbit named Joe lives on a planet with 15% the gravity of that of earth. Joe loves to bungie jump. During one of his more adventurous endeavors, Joe ties a rope to himself and a bridge, leaving exactly 2m worth of slack. Joe...

My professor has provided me with an equation, and my task is to write a conservation of energy problem whose solution would produce said equation.
Here is the equation:
(1/2)(3kg)(7m/s)^2 + 0 + (0.15)(3kg)(9.8m/s^2)(2.0m) = 0 + 0 + T(2.0m)

I would do that, but the magnitude of the magnus force is not equal to the cross product of the angular velocity and velocity vectors, it is only in that direction.
I need to multiply the magnitude (I have it) by a mess of trigonometric functions.
The pure math of the problem:
I have two vectors, both of which are expressed in spherical coordinates. I know the magnitudes as well as the polar and azimuthal angles that express these vectors.
In addition, I have a third vector. I only know the magnitude of this vector, and I need to...

A mosquito of mass .15mg is found to be flying at a speed of 50 cm/s within an uncertainly of .5 mm/s.
a) How precisely can it's position be known?

That makes sense because frequency will be highest (and wavelength smallest) when energy is maxed.
But, assuming that I solved for maximum energy, what would be minimum energy?
Homework Statement
In a television, an electron is accelerated through a potential difference of 30,000 V. What is the minimum wavelength produced.
Homework Equations
E = qv
E = hf
The Attempt at a Solution
I figured that we should first find total energy.
E = qv => E = (1 x...
is it possible for two capacitors the following two capacitors to exist: one has a capacitance of 4F and a charge of +q, and the other has a capacitance of 2F and a charge of +5q.
I think that is it because capacitance is simply a constant that describes the rate of change of charge per unit...
This is not so much a homework as just a general question.
I understand the reasoning behind capacitors in a series all of have same charge, which consequently causes each one to have a separate voltage. But why do capacitors in parallel not have the same amount of charge. They all receive...
Homework Statement
Two capacitors of 2.0F and 5.0F are connected in series; the combination is connected to a 1.5 volt battery. What is the charge stored on each capacitor? What is the potential difference across each capacitor?

C = Q / (Delta)V

Alright. I don't understand the fundamental quantum basis behind the attraction of two magnets. My book notes that magnets manifest themselves when a material such as iron has unpaired electrons in orbitals that spin in the same direction. If an electron is paired, the electrons will spin in...
One biased professor does not say anything about humanities - perhaps it may comment on a particular type of professor that may teach them... but other than that, the argument is completely invalid.
The only wrong answer in an English class is one that cannot be adequately supported with...
Humanities may be graded more subjectively, but there is a right way and a wrong way to do things. There is a reason why some people can ace all of these "squishy" classes. I would argue that it is easier to do well in a humanity because there is subjectivity to grading process.
In a math or...
