A) Conversion from Fahrenheit to Celsius:
The relationship between the two scales is the following
T_f =  \frac{9}{5}T_c + 32
where
T_f is the temperature in Fahrenheit
T_c is the temperature in Celsius

Re-arranging the formula, we find the inverse relationship:
T_c= \frac{5}{9}(T_f-32)
and we can use this equation to convert T_f = 89.3^{\circ}F into Celsius:
T_c =  \frac{5}{9}(89.3-32)=31.7^{\circ} C

(b) Conversion to Kelvin scale:
The conversion between Celsius scale and Kelvin scale is easier:
T_k = T_c + 273.1
where T_k is the temperature in Kelvin. Using T_c = 31.7^{\circ} C, we find
T_k = 31.7 + 273.1 = 304.8 K

How does Newton's third law of motion describe forces?
svetlana [45]
I would say your answer is B, since Newton's 3rd law is, "For every action, there is an equal and opposite reaction."
It's talking about pairs of actions. Sorry if I'm wrong.

Morgarella [4.7K]

Answer:

Angular velocity (w) = 8.86 rad/s

Explanation:

Angular velocity (w) = \sqrt{} 4ghi/R^{2}

g= 9.81 m/s

R= 0.5

hi (initial depth) = 0.5m

Hence= \sqrt4* 9.81* 0.5/0.5^{2}  = 8.86 rad/s
