calculate the frequency and time period of sound wave of 35 m wave length propagating at a speed of 3500m/s​

Answers

Answer 1

Answer:

Frequency = 100 Hz

Time period = 0.01 sec

Explanation:

f= 3500/35 = 100

T = 1/f = .01

what is the relationship between the variables on this graph? The temperature does not have an effect on flow time. As the temperature increases, the flow time increases. As the temperature increases, the flow time decreases.

Answers

Answer: As the temperature increases, the flow time increases.

Explanation: i took the test

The relationship between the variables on this graph is that As the temperature increases, the flow time increases, therefore the correct answer is option B.

What is the kelvin scale of temperature?

It is a scale of temperature used to measure the temperature, the kelvin scale of temperature is also known as the absolute scale of temperature.

The Standard International unit of thermodynamic temperature is the kelvin, often known less frequently as the degree Kelvin. The formal definition of one kelvin is 1/273.16  of the thermodynamic temperature of pure water's triple point.

As shown in the graph as the temperature increase across the X axis the flow time is increasing as well, these two variables are directly proportional to each other.

Thus, The graph shows a link between the variables, showing that when the temperature rises, flow time also rises, hence option B is the proper response.
