The deuteron is a bound state between a proton and a neutron (and the nucleus of the H2 isotope).
The binding energy of the deuteron is 2.2MeV. What is the mass of the deuteron?
Mp = 938.3 MeV/c^2
Mn = 939.6 MeV/c^2

If you have a simple circuit with only a battery and a parallel plate capacitor with a dielectric, what exactly happens when the battery is turned on?
Also, if the voltage of a capacitor with a dielectric is less than the EMF of the battery, what happens to the rest of the voltage?
I was messing around proving the area of a circle using trigonometric substitution. However, I ended up with area = -πr^2.
In my integral I ended up using trigonometric substitution and setting x = r*cos(theta)
However, this yields x = -r*sin(theta)*d(theta).
When that's substituted...
1. In a certain binary-star system, each star has the a mass of 1.36e30 kg, and they revolve about their center of mass. The distance between them is 1.1e8 km. What is their period of revolution in Earth years?
gravity = centripetal force
(g*m*m)/d^2 = (mv^2)/r
3. I've tried plugging...
1. In Figure 8-49, a block is sent sliding down a frictionless ramp. Its speeds at points A and B are 1.90 m/s and 2.60 m/s, respectively. Next, it is again sent sliding down the ramp, but this time its speed at point A is 3.85 m/s. What then is its speed at point B?
1. Find the value of (f o g)^1 at the given value of x.
f(u) = 1-(1/u)
u = g(x) = 1/(1-x)
x = -1
2. Chain rule...
3. Okay, so the derivitive of 1-(1/(1/(1-x))) is 1. Also, the derivitive of 1/(1-x) = 1/(x-1)^2. So, in theory, shouldn't the answer be 1/4? I've solved this in...
Four firefighters hold a square net, one at each corner. Each person exerts a force of 190 N whose line-of-action passes through a point just below the center of the net and makes an angle with the vertical of 50°. What is the net force the firefighters exert on the net...
