BABU BANARASI DAS NATIONAL INSTITUTE OF TECHNOLOGY & MANAGEMENT, LUCKNOW DEPARTMENT OF PHYSICS B.Tech. 1st year ASSIGNMENT- 1 (RELATIVISTIC MECHANICS) 1. Prove that a frame moving with constant speed along the positive x-direction relative to an inertial frame will also be inertial. 2. A ball has velocity (4i – 5j +10k) m/s relative to the train moving with velocity (3i + 4j) m/s relative to an observer in ground. Calculate the velocity of the ball relative to the ground. 3. Using the concept of Lorentz Fitzgerald contraction. Show that in Michelson Morley experiment t1=t2 4. In Michelson Morley experiment the distance of mirrors from the glass plate is 11 m and the orbital velocity of earth is 3X104 m/s. The wavelength of light used is 5500Å. Calculate the fringe-shift of fringe pattern. (Given c=3X108 m/s) 5. Show that from Lorentz transformation that events simultaneous (t1=t2) at different positions (x1≠x2) in the reference frame S are not in general simultaneous in another reference frames S’. 6. In an inertial frame S, a red light and a blue light are separated by a distance ∆x=2.45km. with the red light at the larger value of x. The blue light flashes and 5.35 μs later the red light flashes. Frame S’ is moving in the direction of increasing x with speed v = 0.855c. What is the distance between two flashes and the time between them as measured in S? 7. A cube of volume V0 and density ρ0 with respect to frame S is placed on x-axis of the frame. Frame S’ is moving with constant velocity v along positive x- direction relative to a stationary frame S. Show that the volume and density of this cube will be V= (V0 / γ ) & ρ = ρ0 γ2 where γ = 1/√(1- v2/c2) 8. Prove that the rest mass of photon is zero. 9. Calculate the percentage contraction of a rod moving with velocity 0.8c m/s in a direction inclined at 60° its own length. 10.

...Week 1 Activity—Pseudocode and Visual Basic
-------------------------------------------------
TCO 1—Given a simple business problem, design and desk-check a solution that is expressed in terms of pseudocode, flowchart, and/or input-process-output (IPO) diagrams.
-------------------------------------------------
Assignment
This activity will assist you in the understanding of how output should appear after statements are executed (results) and how to write proper pseudocode, as well as the relationship between pseudocode, flowcharts, and programming language code.
1. Show the result of each pseudocode program.
2. Also rewrite the pseudocode statements or flowchart using Assignment statements.

...Proportions
Problem 1
Bear population. To estimate the size of the bear population on the Keweenaw Peninsula, conservationists captured, tagged, and released 50 bears. One year later, a random sample of 100 bears included only 2 tagged bears. What is the conservationist's estimate of the size of the bear population?
I think using a simple ratio equation would work here,
let b = bear population
=
cross multiply
2b = 50*100
2b=5000 divide 2 by 5000
5000 =b
2
b=2500 answer
Problem 2
For the second problem in this assignment I am asked to solve this equation for y. The first thing I notice is that it is a single fraction (ratio) on both sides of the equal sign so basically it is a proportion which can be solved by cross multiplying the extremes and means.
y-1 = -3 this problem is a proportion
x+3 4
y-1 (x+3 = -3 (x+3) multiply both sides by x+3 – using the extreme means
x+3 4 property
y-1= -3x+3 add 1 to 3. A number that appears to be a solution but causes 4 0 in a denominator is called an extraneous solutions
y=-3x+4
4 answer
The form of equation I ended up with in problem 10 would be a linear equation. I noticed that the coefficient of x is different than the original problem is that x+3 and in my problem it is -3x/4. I could solve the problem by cross...

...specify in a variable declaration?
You must specify the variable type and an identifier.
int n; // type - int, identifier - n
6. What value is stored in uninitialized variables?
is a variable that is declared but is not set to a definite known value before it is used.
Algorithm workbench
3. Write assignment statements that perform the following operations with the variables a, b, and c.
a. Adds 2 to a and stores the result in b
b. Multiplies b times 4 and stores the result in a
c. Divides a by 3.14 and stores the result in b
d. Subtracts 8 from b and stores the result in a
Assignment statements that perform operations with the variables a, b, and c* (*Actually none of these operations involves the variable c at all... is this an error, or a 'trick answer'?):
b = a + 2
a = b * 4
b = a / 3.14
a = b – 8
4. Assume the variables result, w, x, y, and z are all integers, and that w = 5, x = 4, y = 8, and z = 2. What value will be stored in result in each of the following statements?
a. Set result = x + y
b. Set result = z * 2
c. Set result = y / x
d. Set result = y – z
result = x++ - y;
Answer -4
result = 4 – 8 = -4
result = ++w + y;
Answer
w = w + 1 = 5 + 1 = 6
result = 6 + 8 = 14
5. Write a pseudocode statement that declares the variable cost so it can hold real numbers.

If x > 100 then
Y=20
Z=40
End if
2.) Design an if-then statement that assigns 0 to the variable b and assigns 1 to the variable c if variable a is less than 10. (Simple if statement)
3.) Design an if-then-else statement that assigns 0 to variable b if variable a is less than 10, otherwise it should assign 99 to variable b. (Alternative if statement)
If a < 10 then
B = 0
Else
B = 99
End f
4.) The symbols >, <, and == are all Relational operators.
5.) The if-then statement is an example of a conditioal structure.
6.) The Selection structure is based on boolean logic.
7.) The if-else statement is know as a dual alternative decision structure.
