Chapter name please then I can answer
\Delta L= \alpha L_0 (T_f-T_i)
= (18 x 10^-6 /°C)(0.125 m)(100° C - 200 °C)
= -0.00225 m
New length = L + ΔL
= 1.25 m + (-0.00225 m)
= 1.248
So your answer is B.
For thermometers to read temperatures correctly, they must be immersed in the substance being measured while reading the temperature. When they are taken out the substance, there is a possibility that the fluid inside would change its level due to the sudden change in the temperature. Thus, giving you an erroneous reading of the temperature.
Answer:
Explanation:
The speed is 0.7 m/s.
The distance covered is 1609 m.
Multiplying both sides by <em>t</em>.
Then dividing both sides by 0.7.
It would take 2298.57 seconds.
That would be false hope this helps
