Homework Statement
Write a MIPS assembly language program that accomplishes the following tasks:
1. The program will prompt the user to enter an Integer between 1 and 10.
If the entered number doesn’t satisfy the above condition, use a loop and prompt the
user for a new entry (until a valid...
thank you for your quick response,
is y=\sqrt{1-x^2} a circle?, oh a circle isn't continuous so i can't do antiderivatives?
i have learned substitutions but if i let u be 25-x2, du = -2x dx, i would have to put a (-1/2x) in front of the integral, then integrate u to be (2/3)u3/2, wouldn't i...
Homework Statement
Find the exact value of: ∫-55 √25-x2 dx without using your calculator. (Hint: Consider the geometric significance of the definite integral.)
Homework Equations
integrate and find antiderivative and evaluate at A and B.
The Attempt at a Solution
∫-55 √25-x2 dx...
thank you for your reply
so would the whole proof be
1.A ∩ (A ∪ B) is a subset of A
x is a element in A ∩ (A ∪ B)
x is a element in A by definition of intersection
Therefore A ∩ (A ∪ B) is a subset of A
2.A is a subset of A ∩ (A ∪ B)
x is a element in A
x is a element in...
Homework Statement
Prove the second absorption law from Table 1 by showing
that if A and B are sets, then A ∩ (A ∪ B) = A.
Homework Equations
Absorption laws
A ∪ (A ∩ B) = A
A ∩ (A ∪ B) = A
The Attempt at a Solution
i will show A ∩ (A ∪ B) is a subset of A
x is any element in A...
Thanks you for responding. You were right, I just did the sum of the entropy loss and gain and got an answer of .5629265733 J/K. Webassign marked my answer as right. Thanks again for your help!
Homework Statement
b) The temperature inside a house is Tin = 19.2° C when the temperature outside is Tout = 10.7° C. If Q = 5.49 kJ of heat leak from the house to the outside, find the change in entropy caused by this process.
Homework Equations
W = QH - QC, dS = dQ/T

Homework Statement
An engine operates with n = 1.94 moles of a monatomic ideal gas as its working substance, starting at volume VA = 21.4 L and pressure PA = 2.77 atm. The cycle consists of:
- A to B: an isobaric expansion until its volume is VB = 50.1 L
- B to C: an isochoric (constant...
Thank you grzz and mtayab1994 for responding. It would be easier if the problem did provide n to use PV = nRT. I am confused, should I be using .008 kg for the mass because helium gas has 2 atoms?
Homework Statement
c) Find T, the temperature at which He gas molecules have an rms speed of v = 733 m/s.
Homework Equations
Vrms = √(3kT/m)
The Attempt at a Solution
(Vrms2m)/3k = T
(7332*.004kg)/(3*1.381e-23J/k) = T
5.187e25k = T
Any help with figuring out what I did wrong...
Homework Statement
What is the difference between molecular mass and molar mass? Are they related?
Homework Equations
moles = total mass/ mass/mole
The Attempt at a Solution
I can't find any explanation in my lecture notes.
I think that:
molecular mass = mass of one molecule...
Thank you phyzguy and SammyS for responding. After taking into account about what you said, I realized that the 32s cancel themselves and ended up only needing to take 5/9 of 13.7. I got an answer of 7.61 Celsius degrees. Is this the correct?
Homework Statement
a) One day, the temperature outside changed by 13.7 degrees on a Fahrenheit thermometer. By how much did the temperature change on a Celsius thermometer?
Homework Equations
F = (9/5)C + 32
The Attempt at a Solution
F2 - F1 = 13.7
(9/5)C2 + 32 -(9/5)C1 + 32 = 13.7...
