From this data I am having a hard time finding Inertia
Calculated, Inertia Total and I0.
In this case Inertia Calculated is 1/2 * M (R1^2 +
R2^2) and Inertia Total is MgRp/alpha - MRp^2. Rp = 12.5 mm and M =
10 grams.

Please Exaplain with calculations. I am having a very hard time
with this problem!
II: Magnetic field Due in 7 hours, 48 y1 Two wires carry current 11-49 A and 12-25 A in the opposite directions parallel to the x-axis at y1·4 cm and y2-15 cm, where on the y-axis (in cm) is the magnetic field zero?
i am very confused with these questions. can someone help me
solve? and can you explain neatly and clearly? will rate, thank
you.
1. In this experiment, you will be generating time measurements that have both random uncertainty (Stran) and systematic uncertainty (dtsys). Using Eq. 4 as a starting point, write down an equation that will allow you to calculate &t from Stran and otsys 2. The acceleration due to gravity is related to the time, t, it takes the...
I am getting an error in R and am unsure how to correct it. I am
getting an error from the r2 line, "Error in xc[1:(n - 2)] : only
0's may be mixed with negative subscripts."
tmpFn <- function(xVec)
{
xc <- xVec - mean(xVec)
denom <- sum(xc^2)
n <- length(x)
r1 <- sum( xc[2:n] * xc[1:(n-1)] )/denom
r2 <- sum( xc[3:n] * xc[1:(n-2)] )/denom
list(r1 = r1, r2 = r2)
}
tmpFn(seq(2, 56, 3))
10. (a) Given a...
I attempted it, assuming that x is very small. I am not sure
what I did wrong.
If the K, of a monoprotic weak acid is 7.9 x 10-6, what is the pH of a 0.49 M solution of this acid? pH= 5.257
(MATLAB Question) I'm trying to create an equation of a line (y=mx+b) based on “x” with slope m=2 and y-intercept 2. (y=2x+2). Then plot the line and turn hold on. This is what I have so far, I know something is wrong, but I am not sure at what part. Y=mx+b; Y=2x+2; m=2; y-intercept=2; (plot(x,y)) (plot hold on)
Here is my issue with this problem. For part B, I believe I am
using the right method; for S2-S1 using table values I am getting
0.54336 kJ/K. The formula for total S is supposed to be
S total = (S2-S1) - Q/T. But for Q/T I am getting a little over
the other value giving me a negative answer. It just is not seeming
right. This when plugged in, doesn not give 0.056 kJ/K which is
apparently correct. Someone...
I'm kind of new to programming, and I am having trouble figuring out why my program isn't running. Below is the code that I wrote for practice. I will comment where it says the error is. So the error that I'm getting is "error: no match for 'operator>>' (operand types are 'std::istream {aka std::basic_istream<char>}' ". I'm not sure why I'm getting this because I added the library <iostream> at the top. Thank you. Code: #include <iostream> using namespace std; class...
I highlighted the row I am having a constant syntax error issue. import struct record = open("block.dd") def open(file): try: record = open(block.dd, "rb") record = bytearray() record = file.read(2048) file.close() finally: return record def search_record(x, y): try: search = x[y] except(IOError): print('Cannot search') else: return search status = 0x1BE if status == 0x80: print("Status: Active") else: print("Status: Not active") ptype = record[0x1BE+4] print("The partition type is " + str(search_file(record, ptype)) address = struct.unpack("<i", record[0x1BE+8:0x1BE+12]) print("Address of the first sector...
I have a chem final next week and I have a question I am stuck on. If you solve, please explain the steps. I will 'like' your response. Thanks in advance! 1. Calculate how many mL of 0.10M KOH must be added to 100.0mL of 0.20M formic acid solution to make a pH = 3.50 buffer. pKa(HCOOH) = 3.74 I keep getting 115mL by plugging in all given info to the equation pH=pka+log(b/a) and solving for x then converting to...
