The statement that is true of thermometers is; The temperature reported by a thermometer is never precisely the same as its surroundings.

<h3 /><h3>What is the function of thermometer in an experiment?</h3>

In the experiment to determine the specific heat of a material, the theory will be one which explains that when a heat interchange takes place between two bodies that were having different temperatures at the beginning, the quantity of heat the warmer body looses is equal to that gained by the cooler body to reach the equilibrium temperature. This is true only if no heat is lost or gained from the surrounding.

Now, If heat is gained or lost from the surrounding environment, the temperature readings by the thermometer will be incorrect. The experimenter should therefore have in mind that for accurate results, the temperature recorded by the thermometer is similar to that of the surrounding at the beginning of the experiment and if it differs then note that  heat is either gained or lost to the environment.

A tortoise and a hare engage in a race. A tortoise can run with a speed of 0. 15 m/s. A hare can run 25 times as fast as the tor
Nonamiya [84]

Let D be the total length of the race, and T the time it takes for the tortoise to finish it. Then

D = (0.15 m/s) T

Let t be the time after the start of the race when the hare decides to take a nap. In this time, the tortoise travels a distance

(0.15 m/s) t

and the hare travels

25 (0.15 m/s) t = (3.75 m/s) t

For the next 5.0 min = 300 s, the tortoise keeps moving and covers a distance of

(0.15 m/s) (300 s) = 45 m

while the hare covers no distance.

After these 300 seconds, the remaining time for the tortoise to complete the race is (T - t - 300 s). In this same time, the hare loses the race by 35 cm = 0.35 m, so overall it has covered a total distance of

(3.75 m/s) t + 0 (300 s) + (3.75 m/s) (T - t - 300 s) = D - 0.35 m

Solve for T :

(3.75 m/s) t + 0 + (3.75 m/s) T - (3.75 m/s) t - 1125 m = D - 0.35 m

(3.75  m/s) T - 1125 m = D - 0.35 m

(3.75 m/s) T - 1125 m = (0.15 m/s) T - 0.35 m

(3.60 m/s) T = 1124.65 m

T = 312.403 s

(b) So, the race takes about 312 seconds, or 5.21 minutes.

(a) It also follows that the race has a total length of

D = (0.15 m/s) (312.403 s) ≈ 46.9 m
