Neutrinos are described in the text. They are emitted by the Sun, and we now know that they change their form, so they must experience some measure of time. This tells us that neutrinos
1. have zero mass.
2. have some mass.
3. have infinite mass.

2 ) HAVE SOME MASS.
a neutrino is a sub atomic particle ( fermion ) which mostly do not react to normal matter.
they are of three types.
1.electron neutrino
2. muon neutrino
3. tau neutrino
for so many years the world thought that neutrinos have no mass (zero mass)
but later experiments showed that they have a mass which is closer to zero ( but not zero! )

1. How do we know the phenomena of the sun are magnetic? 2. What process do low/medium mass stars use to fuse H to He? 3. What process do higher mass stars use to fuse H to He? 4. how is the magnetic field of the earth generated? how does it change over time? 5. What planet was impacted so hard that its tilt now causes its poles to face the sun? 6. Why are bi polar jets a sign...
In the project I am working right now, we have some python and some C# code. At some point, I call from python a subprocess which starts a C# executable. This C# code returns an error code, which has to be understood on the python side and a readable report has to be created. This means, both sides "must speak the same language". So, at the end I have to handle a mapping {error codes: readable explanation} (normally we implement...
1) Up until now we have always ignored air resistance. We should now add it. Let us just think of simple 1-dimensional problem, dropping a ball of mass m from a height H but with air resistance. We can model the air resistance as a force proportional to the velocity, fair = bu. The coefficient b is a constant. (For this problem you can use calculus textbooks or wolfram alpha to do the calculus.) • What are the units on...
Problem 4 Suppose we know that a particle of mass is stuck on the x-axis, confined to the region -1<x< 1. Its wavefunction is given -x) -1 << < 1 < -1 or 2 > 1 where A is a real, as-yet-undetermined constant. We'll assume that all numbers are in Sl units, without actually writing the units down. a) Draw a set of graph axes below like the one below and draw a sketch of this wavefunction on the axes....
please explain the answer

We want to develop a code that calculates In(1 - x) =- on the interval -1<x<1. First, understand what this notation represents. The capital sigma (2) indicates that a summation of terms is to be performed. (The term summation still applies even though all the terms are negative.) We are also given the prototype term written in terms of x and n. The notation also tells us that...
Now we consider a black hole of the same mass as the Sun: Mbh 2 x 1050 k (a) (2 marks) Show that if you are launching a rocket with velocity v upwards from a planet of mass M, you can only escape the planet's gravity if you start from a radius r > 2GM/v2 Hint: Use Newtonian mechanics What if your rocket is acutally a beam of light? If we forget about relativity for a minute, we can put...
(15 points) Encounter with a semi-infinite potential "well" In this problem we will investigate one situation involving a a semi-infinite one-dimensional po- tential well (Figure 1) U=0 region 1 region 2 region 3 Figure 1: Semi-infinite potential for Problem 3 This potential is piecewise defined as follows where Uo is some positive value of energy. The three intervals in x have been labeled region 1,2 and 3 in Figure 1 Consider a particle of mass m f 0 moving in...
Newton's version of Kepler's Law Force Example Use what we know about the earth's orbit to estimate the mass of the sun. For this problem we can use Newton's form of Kepler's law Solving for the sum of the masses we get to use this law we need all our values to be kilograms, meters, and seconds. a 1AU-149.6x10P m and p- 1 year (365.25 days/year)(24 hours/day)(3600 seconds/hour)-3.15x 10" sec. Placing these values in to our equation we get M+...
