An X-ray has a frequency of 4.37 × 1018 Hz.  What is the wavelength?

The term ___________ refers to a situation in which a  large corporations control an industry.

In Lab 1, you performed a serial dilution of [DYE] using [DILUENT] as a diluent. You quantified your samples by measuring how much they absorbed light at [WAVELENGTH]. As concentration decreased, absorbance should have [TREND]. 

You are growing up your protein in LB/Kan broth. You pour your 20mL preculture that grew overnight into 980mL of LB/Kan broth. You place your LB/Kan broth into the incubator at 37oC and check the OD600 every 30 minutes. After your media makes it to an OD600 of 0.5, you add in 1M IPTG to achieve a final concentration of 1.0mM. How much IPTG did you add to the media in order to achieve a final concentration of 1.0mM? Please give your answer in

The mutual inductance for these two coils is 0.006 Henries.  The current in the first coil is changing at the rate of 3.5 Amperes/second.  What would be the emf generated in the second coil?

Some of the ATP stock from the previous question is diluted to a volume of 1 L and a concentration of 7 ug/mL. How much of the ATP stock was used? Give your answer in mL. 

You have a stock container of 5X buffer, but your experiment requires 1X buffer. If you want to make 1.5 L, how much of the 5X buffer do you need? Please give your answer in mL.

Two charges of opposite sign and equal magnitude Q = 0.82 C are held 2.0 m apart as shown in the figure. Reference: Ref 19-5 Determine the electric potential at the point P.

Before the 1880s, most immigrants came from _________; after the 1880s, most immigrants came from _______.

The figure below shows four parallel plate capacitors: A, B, C, and D. Each capacitor carries the same charge q and has the same plate area A. As suggested by the figure, the plates of capacitors A and C are separated by a distance d while those of B and D are separated by a distance 2d. Capacitors A and B are maintained in vacuum while capacitors C and D contain dielectrics with constant κ = 5. Reference: Ref 19-9 Which capacitor is storing the greatest amount of electric potential energy?
