In aqueous solution , hydrogen sulfide reduces $\mathrm { Br } _ { 2 }$ to $\mathrm { Br } ^ { - }$ In all cases, under appropriate conditions, the product is elemental sulfur. Write a balanced net ionic equation for each reaction.

Assume that the force of a bow on an arrow behaves like the spring force. In aiming the arrow, an archer pulls the bow back 50 cm and holds it in position with a force of 150 N. If the mass of the arrow is 50 g and the "spring" is massless, what is the speed of the arrow immediately after it leaves the bow?

What are the pinout differences between the T568A and T568B standards?

Which statement accurately describes what near end crosstalk (NEXT) is?

• b) NEXT is crosstalk that occurs near the opposite end of a signal source.
• c) NEXT is crosstalk that occurs when an EMI source is near the data signal source
• d) NEXT is crosstalk that occurs only when a cable segment exceeds the bend radius.

B. shielded twisted pair (STP)

C. RG-6 Coaxial

D. fiber-optic

What does backbone cabling consist of?

A. The cables or wireless links that provide interconnection between the entrance facility and MDF, and between the MDF and IDFs.

B. Short length cables with connectors at both ends.

C. The shielded cables that are used for high data transmission rates between an organization and an ISP.

Let $X$ and $Y$ each have support $(0,1)$ marginally, and suppose that the joint PDF $f_{X,Y}$ of $X$ and $Y$ is positive for $0 < x < y$ and 0 otherwise. (a) What is the support of the conditional PDF of $Y$ given $X = x$? (b) Show that $X$ and $Y$ can’t be independent.

The wavelength of absorbed electromagnetic radiation for $\mathrm { CoBr } _ { 4 } ^ { 2 - }$ is $3.4 \times 10 ^ { - 6 }\ \mathrm { m } .$ Will the complex ion $\mathrm { CoBr } _ { 6 } ^ { 4 - }$ absorb electromagnetic radiation having a wavelength longer or shorter than $3.4 \times 10 ^ { - 6 }\ \mathrm { m } ?$ Explain.

Distinguish between living donor transplants and deceased donor transplants. Which type is more common?

Find the product or quotient.

$$\frac { 4 x ^ { 9 } y } { 3 x ^ { 3 } } \cdot \frac { 2 x y } { 8 y ^ { 2 } }$$

In I 899, Charles M. "Mile a Minute" Murphy set a record for speed on a bicycle by pedaling for a mile at an average of 62.3 mi/h (27.8 m/s) on a 3 mi track of plywood planks set over railroad ties in the draft of a Long Island Railroad train. In 1985, a record was set for this type of "motor pacing" by Olympic cyclist John Howard who raced at 152.2 mi/h (68.04 m/s) in the wake of a race car at Bonneville Salt Flats. The race car had a modified tail assembly designed to reduce the air drag on the cyclist. What was the kinetic energy of the bicycle plus rider in each of these feats? Assume that the mass of bicycle plus rider is 70.5 kg in each case.
