Is unit km per hour per second same as km per second per hour?
No. The value km/hr is a speed. The value km/sec/hour is acceleration (how many km/sec do you gain each hour).
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
How many seconds will it take for a satellite to travel 450 km at a rate of 120ms?
3,750 sec
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 66 kilometers per second to kilometers per hour?
(66 km/sec) x (3,600 sec/hr) = 237,600 km/hr
How many kilometer minutes are in a kilometer second?
1 minute =60 sec so, 1 km min =60 km sec
At what speed does each planet orbit the Sun?
Mercury - 47.8725 km/sec = 107,000MPH Venus - 35.0214 km/sec = 78,350 MPH Earth - 29.7859 km/sec = 66,630 MPH Mars - 24.1309 km/sec = 54,000 MPH Jupiter - 13.0697 km/sec =29,240 MPH Saturn - 9.6724 km/sec = 21,640 MPH Uranus - 6.8352 km/sec = 15,290 MPH Neptune - 5.4778 km/sec = 12,250 MPH Pluto (TNO, or dwarf planet) = 10,700 MPH
Is the speed of light in a vacuum 300 thousand km per sec?
about 300,000 km per sec.
A car accelarates uniformly from 36kmhr to 54kmhr in 10s find accelaration and distance traveled by the car during this interval of time?
Acceleration = (change in speed) / (change in time) = [ (54 - 36) km/hr ] / (10 sec) = (18 km/hr) /(10 sec) = (1.8 km/hr-sec) x (3,600 sec / hr) = (1.8 x 3,600) (km - sec / hr2 - sec) = 6,480 km / hr2 Average speed during the 10 seconds = (36 + 54) / 2 = 90/2 = 45 km/hr Distance = (average speed) x (time) = (45 km/hr) x (10 sec) x (1 hr / 3,600 sec) = (45 x 10 / 3,600) (km - sec - hr / hr - sec) = 0.125 km = 125 meters
How fast is the space shuttle at take off?
The space shuttle reached speeds of about 17,500 miles per hour (28,000 kilometers per hour) at takeoff. It accelerated rapidly to escape Earth's gravity and reach orbit around the Earth.
What is speed of light in km persec?
The speed of light in a vacuum is approximately 299,792 kilometers per second.
What is the equation to finding how many kilometers in 1 light year?
Speed of light = 300 thousand kilometers per second.(300,000 km/sec) x (3,600 sec/hr) x (24 hr/day) x (365 day/yr)= (300,000 x 3,600 x 24 x 365) (km - sec - hr - day / sec - hr - day - year)= 9.4608 x 1012 km/yr
What is 120 km per second in scientific notation?
1.2 × 102 km/sec.
How fast is earth moving?
There are several factors that need to be considered when determining the speed the earth is moving. 1-the speed the earth travel around the sun, 2-the speed the earth spins on its axis, 3-the speed our galaxy is spinning, and 4-the speed our galaxy is moving within the universe. 1. earth rotates on its axis at a speed of about 1040 miles/hr (1670 km/hr or 0.5 km/sec) 2. earth revolves around the sun at an astonishing 18.5 miles/sec (30 km/sec) 3. our galaxy is rotating at a velocity of about 155 miles/sec (250 km/sec) 4. our galaxy is moving about 185 miles/sec (300 km/sec) so with all that said, as you stand or sit there reading this NOT moving in fact you are moving at 358.788888888 miles/sec! or for anyone else not in the US... 580.5 km/sec!
What is 34.2 meters per second in kilometers per hour?
(34.2 m/sec) x (3,600 sec/hr) / (1,000 m/km) = 123.12 km/hr (rounded)
How fast do electromagentic waves move?
At the speed of light - about 300,000 km/sec (3 x 108 m/sec)
How are acceleration different from speed?
Acceleration is speed with a time, ex. 15 mph/hour, 150 km/sec/sec.
