A small diameter glass rod is expected to have greater strength than a large diameter glass rod because
(a) a small glass rod has fewer dislocations
(b) a small glass rod has a greater number of dislocations
(c) a small glass rod has a smaller ratio of surface area to volume
(d) a large glass rod would have a greater chance of having a larger flaw size.

If between-groups variance is large, then we have observed a) experimenter effects. b) large systematic variance. c) large differences due to confounds. d) possibly both large systematic variance and large differences due to confounds. QUESTION 3 The larger the F-ratio, the greater the chance that a) a mistake has been made in the computation. b) there are large systematic effects present. c) the experimental manipulation probably did not have the predicted effects. d) the between-groups variation is no larger than...
If S^2- larger or smaller than Cl- a. these two ions have the same size b/c they have the same number of electron b. s^2- is larger b/c it has fewer protons than cl- c. s^2- is larger b/c it exhibits greater electron repulsion d. cl- is larger b/c it has higher mass than s2-
Two circular holes, one larger than the other, are cut in the
side of a large water tank whose top is open to the atmosphere.
Hole 1 is the larger hole, and hole 2 is the smaller hole. The
center of one of these holes is located 8 times as far beneath the
surface of the water as the other. The volume flow rate of the
water coming out of the holes is the same. (a) Decide which hole (1...

1. Forests have greater impacts than small crops over wind flows because of their more dense canopies. With depth below the canopy, wind speed a) exponentially decays but gets a secondary maximum near the surface b) increases c) none of the above
Q3.3. Recall the prediction: Allele frequencies change by genetic drift equally quickly in large populations and in small populations. Is this correct? Why or why not? Yes. Genetic drift is sampling error, and sampling error is unpredictable, no matter the population size. Yes. Small populations experience more sampling error, but large populations have more reproduction overall, leading to similar rates of allele frequency change. O No. In the ferret experiments, allele frequencies changed more quickly in the small populations than...
A cylindrical rod of copper having an initial diameter of 16 mm is to be cold worked by drawing such that the cross-sectional area is reduced. It is required to have a cold-worked yield stress of at least 200 MPa and a ductility in excess of 12%; in addition, the final diameter of 11.3 mm is required. Describe the manner in which this procedure may carried out by answering: (10p) Write the yield strength and ductility before cold work. (15p)...
The blood pressure at your heart is approximately 100 mm of Hg. As blood is pumped from the left ventricle of your heart, it flows through the aorta, a single large blood vessel with a diameter of about 2.5 cm. The speed of blood flow in the aorta is about 60 cm/s. Any change in pressure as blood flows in the aorta is due to the change in height: the vessel is large enough that viscous drag is not a...
