3- Water (T= 20°C) (-10 m²/s) flows at a rate of 0.05 m³/s in a 20 cm cast-iron pipe (relative roughness = 0.12 mm). What is the head loss per kilometer of pipe? L = 1000 m R Water, 20°C Q=0.05 m³/s D= 0.2m Asphalted, cast-iron

250 mA and .2 sec creates a good radiograph of a lateral thoracic spine withappropriate exposure to the IR. The technologist wants to modify this technique to give the patient time to breathe during the exposure. If the time is changed to 2 seconds, what new mA will maintain exposure?

A sample was weighed three times and the following results were obtained: 12.52 g, 12.50 g, and 12.53 g. What is the average weight? Note: The average of a number of successive readings will have the same number of decimal places as are in their sum.   Question 5 options:   a) 12.5166 g b) 12.516 c)12.5 d) 12.52

A radioisotope produces an intensity of 7.52 x 10^4 becquerel (Bq) at a distance of 1.00 cm from the source. What would be the intensity at 12.0 cm? Intensity = ______Bq

2. Consider two gamma radioactive sources: S1 has activity 50 µCi (micro-Curie) and S2 has activity 25 µCi (micro-Curie). They are separated by 1 m. Assume that both sources are pointlike. s1 S2 1 m a) At which location along the dashed line passing by the two sources is the flux due to S1 equal to the flux due to S2 ? b) What is the gamma fluence in that location in a time interval of two minutes ?

When searching for y-component of the same information, would I use a similar method using cos?

A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following data on the isotopes of tin in these samples: isotope 118 "Sn 120 Sn Use these measurements to complete the entry for tin in the Periodic Table that would be used on 98765 ALEKS. Be sure your answers have the correct number of significant digits. Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for tin in the Periodic Table we use here on Earth. 0 Sn mass relative (amu) abundance 117.9 54.% 0 119.9 Continue 46.% X S evee muuraw Hill LLC.
