Answer:
500km/h
Explanation:
I don't know what units you need the answer in, but if the units were to stay the same, then that's the answer^.
Answer:
a) 100Hz
b) opened at both ends
c) 1.72m
Explanation:
Let fun be the nth Harmonic frequency organ. If pipe is opened at both ends.
L= length of pipe
Fyn =(n/x)
550hz= (n/2L)v 1
650hz=(n+1/2L)×v 2
Comparing 1 and 2
650hz= nv/2L + v/2L
550= 343/2L
L= 550×2/343 = 1.7m
c) fundamental frequency
Fo= nv/2L = 343/(2×1.7) = 100Hz

<h3>What is a resistance thermometer?</h3>
A resistance thermometer is a type of thermometer that measures temperature through a change in resistance.
To calculate the resistance of the thermometer at room temperature, we use the formula below.
Formula:
- 100/27 = 2/(x-14.5)..............Eqquation 1
Where:
- x = Resistance of the thermometer at room temperature
Make x the subject of the equation
- x = [(27×2)/100]+14.5
- x = (54/100)+14.5
- x = 0.54+14.5
- x = 15.04 ohms.
Hence, The resistance of the thermometer at room temperature is 15.04 ohms.
