A simple thermocouple circuit, which is composed of type-J thermocouples, is used to measure the temperature of a gas. The open circuit voltage, V0, oscillates in a sinusoidal fashion with a mean of 4.997 mV, an amplitude of 0.541 mV, and a frequency of 2.1 Hz. The measurement system has the time constant τ = 1.7 s. The reference junction temperature is measured with a platinum RTD (a = 0.003927 °C^-1) where R = 1.0275 W and R0 = 1.0000 W with T0 = 25 °C. Calculate the following quantities:

a. The mean gas temperature.
b. The amplitude of the fluctuating gas temperature.

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

answer; (arch); good luck

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
