According to our lab manual, the graph of Wavelength vs Period : the slope should be the speed of sound. Well, I have a negative slope of -32.2 which is ridiculous, but I can't find out what I'm doing wrong. We had 5 tuning forks , say for instance, 512Hz...the inverse
1/f = 1/512= 0.00195 ...
Centauri A and Centauri B are binary stars with a separation of 3.45x10^12m
and a period of 2.52x10^9s
Assuming the two stars are equally massive (which is approximately the case), determine their mass.
( m1 + m2 ) P^2 = ( d1 + d2 )^3 = R^3...
Three identical masses of 550 each are placed on the x axis. One mass is at X1= -10.0 , one is at the origin, and one is at X2= 43.0 .
What is the magnitude of the net gravitational force on the mass at the origin due to the other two masses?
G = 6.673 x 10-11...
A nonuniform horizontal bar of mass m is supported by two massless wires against gravity. The left wire makes an angle (phi) with the horizontal, and the right wire makes an angle . The bar has length L.
What is the position of the center of mass of the bar, measured as...
I have a homework question that is referring to a pivot rod with unequal masses.
The spheres are small enough that they can be considered point particles.
what exactly does this mean?
I know how to solve the equation, but I'm assuming I can't use the I=2/5mr^2 to solve it.
I'm trying to use hooke's law for the spring in the flea's legs.
which would be F=kx
F=(26N/m)(2x(for each leg)(0.0001m)
I got a force of 0.0052
I thought of using PE=mgh, the only equation I know of that would give me the height.
I'm sure it's...
The resilin in the upper leg (coxa) of a flea has a force constant of about 26 N/m, and when the flea cocks its jumping legs, the resilin in each leg is stretched by approximately 0.10mm .
Given that the flea has a mass of 0.55mg , and that two legs are used in a jump, estimate the maximum...
