Question

1. a time and temperature sign on a bank indicates the outdoor temperature is 32°c. what is the equivalent temperature on the fahrenheit scale? (a) -49°f (b) 68.8°f (c) 0°f (d) 86.9°f (d) none of the above 17. which of the following statements is true about temperature? (a) a number that corresponds to the warmth or coldness of an object (b) temperature is related to newtons law of universal gravitation (c) the si unit for temperature is meter per second (d) none of the above 18. all the following are insulators except (a) glass (b) wool (c) wood (d) copper (e) none of the above

Explanation:

Step1: Recall the conversion formula

The formula to convert Celsius ($C$) to Fahrenheit ($F$) is $F=\frac{9}{5}C + 32$.

Step2: Substitute the value of $C$

Given $C = 32^{\circ}C$, substitute into the formula: $F=\frac{9}{5}\times32+32$.
First, calculate $\frac{9}{5}\times32=\frac{288}{5} = 57.6$.
Then, $F=57.6+32$.

Step3: Calculate the result

$F=89.6^{\circ}F$.

• For question 17:
• Temperature is indeed a number representing the warmth or coldness of an object. Newton's law of universal gravitation is about the force between two masses and has no relation to temperature. The SI unit of temperature is Kelvin, not meter per second.
• For question 18:
• Glass, wool, and wood are insulators (poor conductors of heat or electricity). Copper is a good conductor (not an insulator).

Answer:

E. none of the above
