How do you convert 0.720 km into m?
To convert 0.720 km to meters, you simply multiply the value by 1000 because 1 kilometer is equal to 1000 meters. Therefore, 0.720 km is equal to 720 meters.
Use the fact that the speed of light in a vacuum is about 3.00 103 meters per second to determine how many kilometers a pulse from a laser beam travels in exactly 8 hours?
The speed of light in a vacuum is 3.00 x 10^8 m/s. To convert this to kilometers per second, divide by 1000 to get 3.00 x 10^5 km/s. In 8 hours, there are 8 x 3600 = 28800 seconds. The distance the pulse travels is speed x time, so it would be 3.00 x 10^5 km/s x 28800 s = 8.64 x 10^9 km.
Does a sound wave need a medium?
Yes. The speed of sound in a medium depend on the (sq root of the elastic modulus/ the density).The speed of sound in a few metals are :-Beryllium with a speed of about 13 km/sec. (the highest)Potassium has a velocity of sound of about 2km/sec. - (soft metal)Lithium, has a sound velocity of about 6 km/sec.( the lightest metal)Copper a fairly dense but soft metal has a sound velocity of about 3.8km/sec.Osmium about 4.9 km/sec. (The densest metal)Magnesium about 4.9 km/sec. a light metal, but stiff.
How fast does a spot of laser sweep across clouds of a turntable at the top of a mountain and turns 10 revolutions per second if it reaches clouds 10km away?
In km/ seconds: 10km=r= radius Circumference = 2(Pi)(r) = 20km(Pi) = 62.83185307 The laser is making 10 sweeps/ second so times the answer by ten. 200(Pi) km/sec or 628.3185307 km/sec *If you have to go by sig. figs. 600 km/sec. If you don;t know what sig. figs. are ignore this.
What is the wavelength of an electromagnetic wave that has a frequency of 3 kHz a less than 1 km b 1 km c more than 1 km?
a) For a frequency of 3 kHz, the wavelength is less than 1 km, approximately 100 km. b) For a frequency of 3 kHz, the wavelength is 100 km. c) For a frequency of 3 kHz, the wavelength is more than 1 km, approximately 300 km.
How do you convert 20m sec into km hr?
There are 1000 meters in a kilometer(1000 m) / (1 km). There are 3600 seconds in an hour, so (1 hr) / (3600 s). you can just multiply (1 km / hr)*[(1000 m) / (1 km)]*[(1 hr) / (3600 s)] to get 0.28 m/s.
How do you convert a speed of 73.5 km hr to m sec?
73.5 km/hour = 73500 meters/hour = 73500/3600 meters/sec = 20.4166 meters/sec
Convert 66 kilometers per second to kilometers per hour?
(66 km/sec) x (3,600 sec/hr) = 237,600 km/hr
How do you convert kilometer per hour to miles per second?
(1 km/hr) / [ (1.609344 km/mi) x (3,600 sec/hr) ] = 0.0001726 mi/sec (rounded)Multiply [Km/hr] by 0.0001726 to get [mi/sec] .Or divide it by 5,793.6 .
Convert km per hr to meters per sec?
Divided speed by 4, then add 2I.E 40km is 12m a sec
How do you convert kilo joules in to km per sec?
You cannot, the units are incompatible. However a force of x kilojoules of energy will impart an acceleration on a mass of x km per sec.
How do you convert 12.7km h into ms?
To convert 12.7 km/h to m/s, you can use the conversion factor 1 km/h = 0.27778 m/s. Therefore, 12.7 km/h is equal to 12.7 * 0.27778 m/s, which equals 3.53 m/s.
How do you convert km per hour to m per second?
( 1 km/hr ) x (1,000 m/km) x (1/3600 hr/sec) = 5/18 meter/second = 0.2778 meter/second1 meter/sec = 3.6 km/hr
How can you convert the speed of light in km per second by dimensional analysis?
To convert the speed of light from meters per second to kilometers per second using dimensional analysis, we can set up a conversion factor. One kilometer is equal to 1000 meters, so the conversion factor is 1 km = 1000 m. Therefore, we can multiply the speed of light in meters per second by the conversion factor to get the speed of light in kilometers per second.
How do you convert 85 miles per hour to kilimeters per second?
85 mi/h x 1 km/.621 mi x 60 min/1 h x 60 sec/1 min = 492,753 km/sec (490,000 km/sec if you address the concern of significant figures)
What is the formula to convert kilometers per second to miles per hour?
km/sec x 2,236.94 = mph
How do you convert 600 kilometers per second to miles per hour?
(600 km/sec) x (1 mile/1.609344 km) x (3,600 sec/hr) = 600 x 3,600/1.609344 = 1,342,161.8 mph
