AI Thread Summary
To convert kilometers per hour (km/h) to meters per second (m/s), divide the speed in km/h by 3.6. For example, to convert 82.4 km/h to m/s, you would calculate 82.4 / 3.6, resulting in approximately 22.9 m/s. This conversion is based on the fact that there are 1000 meters in a kilometer and 3600 seconds in an hour. Understanding this relationship simplifies the conversion process significantly. Mastering this conversion is essential for physics calculations involving speed.

I am in my first physics class and the professor just kinda skimmed over this but I am lost on how to convert km/h to m/s.

What's the explanation on how to convert 82.4 km/h to m/s?

Thanks in advance for any help.

There are 1000 m in one kilometer.
There are 60 seconds in an hour.

If you want to change from km/h to m/s, you need to divide by 1000 and multiply by 60. Think of it as multiplying by 1: 1 km/h * (1000m/km) * (1h/60s)= (1000/60) m/s
 
Thanks very much.
 
What I usually do is
\frac{1\ km}{1\ h}=\frac{1000\ m}{3600\ s}
which gives
1\ km/h=\frac{1}{3.6}\ m/s
or
1\ m/s=3.6\ km/h
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
