Athermocouple, with a spherical junction diameterof 0.5 mm, is used for measuring the temperature of hot airflow in a circular duct. the convection heat transfer coefficient of the air flow can be related with the diameter (d) ofthe spherical junction and the average air flow velocity (v)as h 5 2.2(v/d)0.5, where d, h, and v are in m, w/m2? kand m/s, respectively. the properties of the thermocouple junction are k 5 35 w/m? k, r 5 8500 kg/m3, and cp 5320 j/kg? k. determine the minimum air flow velocity thatthe thermocouple can be used, if the maximum responsetime of the thermocouple to register 99 percent of the initial temperature difference is 5 s.

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
