Hamish is studying what happens when he sends a sound
horrorfan [7]

Wave 3 will move the slowest, the statement could made about the data collected in Hamish's table

Answer: Option C

<u>Explanation: </u>

Sound waves require medium to pass from one to another. Depending upon the density of molecules in the medium, the speed of the sound waves can be determined. As we know that compression and rarefactions will be formed for propagation of sound waves when the waves collide with molecules of the medium.

So, if there is less molecules present in the medium or loosely packed molecules present in the medium with high mean free path length than the sound wave will be travelling slowly in that medium.

Thus, as we known that gas has the loosely packed molecules among the other states of matter, so wave 3 which is made to pass through the gas medium will be propagation at the lowest speed or will move the slowest compared to other 3 gases made to propagate in solid and liquid mediums.

A truck covers 40 km with an average speed of 80km/h. Then it travels another 40 km with an average speed of 40 km/h. The averag
Yuliya22 [10]

Answer:

Average speed = 53.33 km/h

Explanation:

Below is the calculation for the average speed:

Given the average speed of for first 40 km = 80km/h

Time taken to cover the first 40 km = Total Distance / average speed

Time taken to cover the first 40 km = 40 / 80 = 0.5 hours

Given the average speed of for next 40 km = 40km/h

Time taken to cover the next 40 km = Total Distance / average speed

Time taken to cover the next 40 km = 40 / 40 = 1 hours

Now the average speed of the tuck to cover total distance:

Average speed = Total distance / Total time

Average speed = (40 + 40) / (0.5 + 1)

Average speed = 53.33 km/h
