A bus travelling along a straight road at 100km/hr-1 and the bus conductor make at 6kmhr-1 on the floor of the bus in the same direction on the bus.find the speed of the conductor relative to road and relative to the bus.if the bus conductor now makes at the same rate but in opposite direction as the bus.find his new speed relative to the road.
A requirement to have an annually balanced federal budget would mean:
That there would be no more recessionary gaps or inflationary gaps.
That the role of taxes and transfers as automatic stabilizers would be undermined.
That total household disposable income would be the same every year.
That actual GDP would equal potential GDP every year.
A flock of birds flies due north at 10.3m/s (relative to the air) while a steady cross wind blows due east at 3.5m/s (relative to the ground). Calculate their total distance traveled in 1.2 hours relative to the ground.
For a damped oscillator with a mass of 230 g, a spring constant 140 N/m and a damping coefficient of 74 g/s, what is the ratio of the amplitude of the damped oscillations to the initial amplitude at the end of 29 cycles?
1. For the reaction,
NiO(s) + CO(g) « Ni(s) + CO2(g)
The Kp for the reaction falls from 4540 at 936 K to 1580 at 1125 K.
i. Is the reaction Exothermic or Endothermic ? Explain.
ii. Predict the effect of each of the following on the equilibrium yield of Ni(s) (you should be able to explain why it is so )
a. increasing the total pressure by compression( decreasing the volume of container)
b. Increasing the total pressure by adding an inert gas.
c. Increasing the temperature.
d. Increasing the partial pressure of CO(g)
e. Increasing the partial pressure of CO2(g)
f. removing some NiO(s)
delta Tf = i*Kf*mThe expresssion for the freezing point depression of a solution relative to that of the pure solute is shown above. From solutions of known concentrations of p-dichlorobenzene in cyclohexane, you determine Kf, the freezing point depression constant of cyclohexane. What assumption is necessary in order to do these calculations?
The cornea of the eye has a radius of curvature of approximately 0.500cm , and the aqueous humor behind it has an index of refraction of 1.35. The thickness of the cornea itself is small enough that we shall neglect it. The depth of a typical human eye is around 2.32cm . 1) What would have to be the radius of curvature of the cornea so that it alone would focus the image of a distant mountain on the retina, which is at the back of the eye opposite the cornea?2)If the cornea focused the mountain correctly on the retina as described in part A, where would it focus the text from a computer screen if that screen were 28.9cm in front of the eye?3) Given that the cornea has a radius of curvature of about 0.550cm , where does it actually focus the mountain?For part 1 it hints that this is not as a lens but a spherical object…
2) (9 pts) We have an Hfr strain that is gal+ met+ arg+ ampS and we wish to map the relative position of the met and arg genes. We cross this strain with an F- strain having the genotype gal- met- arg- ampR. We know from an interrupted mating experiment that gal enters last. Note that gal = a carbon source (galactose) while arg and met are amino acids. Amp = an antibiotic.
If you plate on the following media:
Media A) minimal media lacking arginine but containing methionine
Media B) minimal media lacking methionine but containing arginine
Media C) minimal media lacking arginine and methionine
Media D) minimal media containing arginine and methionine
You obtain the following results:
Result 1) 5% of the recombinants are arg- met-
Result 2) 10% of the recombinants are arg+ met-
Result 3) 0% of the recombinants are arg- met+
Result 4) 85% of the recombinants are arg+ met+
Match the media with the correct phenotype.
What other chemical was in all the media? (why?)
Which gene is first?
How would you check to see if the galactose gene has moved?
