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.

Ineed asap! list 3 examples in which friction us or makes things easier in our daily life. explain the effect of friction for each. *make sure you explain the effect of friction for each example! *

Which situation will have the highest resistance? a.long wire and high temperatureb.short wire and high temperaturec.long wire and cold temperaturedshort wire and low temperature

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
