G You have a NTC thermistor which measures 10k Ohm at 25°C and has β= 3500 K. Find the value of Rt (the resistance of the thermistor) at 35°C. What is Vba at 35 degrees Celsius? Answer in volts but do NOT include units. (Hint: Vba = Vb - Va)

R2 = 6832

Vba = 2.03V

Explanation:

The details of the solution have been outlined in the attachment below.

T1 is the first temperature point in Kelvin

T2 is the second temperature point in Kelvin

R1 is the thermistors resistance at temperature T1 in Ohms

R2 is the thermistors resistance at temperature T2 in Ohms

T1 = 298K

T2 = 308K

R1 = 100000Ω

R2 = ?

B = 3500K

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
