Use dimensional analysis to convert the following units. Show your work.

Physics
1 answer:
anyanavicka [17]3 years ago
4 0

Answer:

Explanation:

conversion of 2.5 days to seconds

2.5 days =2.5 days*24 hours*3600 seconds

2.5 days=216000seconds

b) conversion of 25 km to mm

1 km=1000000 mm

therefore

25 km=25*1000000=25000000 mm

c) conversion 22 g to kg

1000 g=1 kg

therefore

22 g=22/1000=0.022 kg

To solve this problem we will apply the concepts related to the Doppler effect. According to this concept, it is understood as the increase or decrease of the frequency of a sound wave when the source that produces it and the person who captures it move away from each other or approach each other. Mathematically this can be described as

f = f_0 (\frac{v-v_0}{v})

Here,

f_0 = Original frequency

v_0 = Velocity of the observer

v = Velocity of the speed

Our values are,

v = 340m/s \rightarrow \text{Speed of sound}

f = 20kHz \rightarrow \text{Apparent frequency}

f_0 = 21kHz \rightarrow \text{Original frequency}

Using the previous equation,

f = f_0 (\frac{v-v_0}{v})

Rearrange to find the velocity of the observer

v_0 =v (1-\frac{f}{f_0})

Replacing we have that

v_0= (340m/s)(1-\frac{20kHz}{21kHz})

v_0 = 16.19m/s

Therefore the velocity of the observer is 16.2m/s
