The metal vanadium becomes superconducting at temperatures below 1.091 K . 

Calculate the temperature at which vanadium becomes superconducting in degrees Celsius. Be sure your answer has the correct number of significant digits. 

Evaluate \( 3000 ( 0.04 ) ^ { 0.2 } \) for  t = 2  and for  t = 4. 

\( 3000 ( 0.04 ) ^ { 0.2 ^ { t } } \approx \square \) when  t = 2 

(Do not round until the final answer. Then round to two decimal places as needed.) 

\( 3000 ( 0.04 ) ^ { 0.2 ^ { t } } \approx \square \) when  t = 4

(Do not round until the final answer. Then round to two decimal places as needed.) 

Evaluate the following logarithms. 

(a) \( \log 5 \)           (b) \( \ln 72 \)             (c) \( \log 64,750\) 

(a) \( \log 5 = \square \) (Round to three decimal places as needed.) 

(b) \( \ln 72 = \square \) (Round to three decimal places as needed.) 

(c) \( \log 64,750 = \square \) (Round to three decimal places as needed.) 

Evaluate the following expression for k = 2 and n = 4. 

\( 19,000 ( 1 + \frac { 0.11 } { k } ) ^ { kn } \) 

\( 19,000 ( 1 + \frac { 0.11 } { k } ) ^ { kn } = \square \) 

(Do not round until the final answer. Then round to two decimal places as needed.) 

A student sets up the following equation to convert a measurement. 

(The ? stands for a number the student is going to calculate.) 

Fill in the missing part of this equation. Note: your answer should be in the form of one or more fractions multiplied together 

\(( 50 . \frac { kg \cdot m } { s } ) \cdot \square = ? \frac { g \cdot cm } { s } \)
