if the average speed of a helium atom at a certain temperature is 1130. m/s, what is the speed in miles per hour? (1 mi =1609m)
To convert the average speed of a helium atom from meters per second to miles per hour, follow these steps:
Step 1: Convert the speed from meters per second to kilometers per hour.
Since 1 kilometer is equal to 1000 meters, we can convert meters per second to kilometers per hour by multiplying by 3.6.
1130 m/s * 3.6 km/h = 4068 km/h
Step 2: Convert the speed from kilometers per hour to miles per hour.
Since 1 mile is equal to 1.609 kilometers (or 1609 meters), we can convert from kilometers per hour to miles per hour by dividing by 1.609.
4068 km/h ÷ 1.609 = 2528.34210 mph
Therefore, the speed of a helium atom at a certain temperature is approximately 2528.34 miles per hour.
To convert the speed from meters per second (m/s) to miles per hour (mi/h), we can follow these steps:
Step 1: Convert the speed from meters per second (m/s) to kilometers per hour (km/h).
Step 2: Convert the speed from kilometers per hour (km/h) to miles per hour (mi/h).
Let's calculate it step by step:
Step 1: Convert m/s to km/h
To convert from m/s to km/h, divide the speed in m/s by 1000 and then multiply it by 3600 because there are 1000 meters in a kilometer and 3600 seconds in an hour.
The conversion formula is:
Speed in km/h = (Speed in m/s) * (3600/1000)
Given that the average speed of the helium atom is 1130 m/s, let's substitute it into the formula:
Speed in km/h = 1130 * (3600/1000) = 4068 km/h
Step 2: Convert km/h to mi/h
To convert from km/h to mi/h, divide the speed in km/h by the conversion factor, which is 1.609 because 1 mile is equal to 1609 meters.
The conversion formula is:
Speed in mi/h = (Speed in km/h) / 1.609
Let's substitute the speed in km/h into the formula:
Speed in mi/h = 4068 / 1.609 ≈ 2530 mi/h
Therefore, the speed of the helium atom at a certain temperature, which is 1130 m/s, is approximately 2530 mi/h.
