its known that the speed of light is =3 x 108 m/s
and speed=distance/time distance=speed x time
=3 x 108 m/s x 60
=18 x 109 metres
its also known that 1000m=1kilometre
18 x 109 metres=18 x 106 kilometres
hence distance travelled by light in 60 seconds is 18 x 106 kilometres in vaccuum
What else can I help you with?
What does the phrase light year mean?
a lightyear is a measure of distance that is the distance light will travel in one year. yes also it can travel in 24 hours
How many years are in 1 light year?
9,460,730,472,580.8 km Light travels at 299,792.458 km/sec. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365.24 days in a year. Multiply all those together to get the distance that light travels in one year.
How long to travel from the sun to Mercury?
Mercury is about 57,500,000 kilometers (36,000,000 miles (36 million miles)) from the Sun, Earth is about 152,000,000 (93,000,000 miles (93 million miles)) - a little less than 3x farther away. Since it takes about 9 minutes for light to get to Earth from the Sun, it stands to reason it would take about 3 minutes to get to Mercury from the Sun.Light to Earth152,000,000,km/300,000km/s ~ 506 secs, 506secs x 1 min/60 secs ~ 8.5 mins(93,000,000 miles/ 186,292 miles per second ~ 499 seconds, 499 seconds x 1 min/60 seconds ~ 8.3 mins, )Light to Mercury57,500,000 kilometers/300,000km/sec ~ 192 sec, 192 sec x 1 min/60 secs ~3.2 mins(36,000,000 miles/186,292miles/sec ~ 193 sec, 193 sec x 1 min/60 secs ~ 3.2 mins)
Would you use less electrical energy burning a 60 watt light bulb for 900 seconds or a 100 watt light bulb for 500 seconds?
It would use less electrical energy to burn the 60 watt light bulb for 900 seconds. This is because the total energy consumed is calculated by multiplying the power (in watts) by the time (in seconds), so for the 60 watt bulb: 60 watts * 900 seconds = 54,000 watt-seconds, and for the 100 watt bulb: 100 watts * 500 seconds = 50,000 watt-seconds.
How can you convert the speed of light in km per second by dimensional analysis?
What do you want to convert it to ??Example: Convert [ 'Q' km per second ] to [ miles per minute ].Use:(60 sec/min) = 1(1 mile/ 1.609344 km) = 1(Q km/sec) x (60 sec/min) x (mile/1.609344 km) = (Q x 60/1.609344) x (km-sec-mile/sec-min-km)= 37.2823 Q mile/min
How long does it take light to travel from the sun to Saturn in units of sec?
Saturn is about 75 light-minutes from the Sun, so multiply that by 60 to get light-seconds.
How many feet will you travel going 60 mph in 6 sec.?
60 mi/hr * 1 hr/60 min * 1 min/60 sec * 5280 ft/mi = 88 ft/sec; so 60 MPH is 88 ft/sec. Multiply 88 ft/sec * 6 sec = 528 ft.
How far do you travel at 60 mph in 1 sec?
88 feet, which is one sixtieth of a mile, as you would be travelling one mile per minute.
How far do you travel at 45 mph in 1 sec?
1 min = 60 sec 1 hour = 60 min = 60 × 60 = 3600 sec → 1 sec = 1/3600 hr distance = speed × time = 45 mph × 1 second = 45 mph × 1/3600 hr = 45 × 1/3600 miles = 1/80 mile = 1 chain = 22 yards = 66 feet
How fast must you travel to go 990 feet in 1 sec?
Clear your units. 990ft/sec * 60 sec/minute * 60 min/hour = 3,564,000miles/hour or 3.564x10^6 miles per hour.
How fast nerve signals travel to the brain per sec?
Nerve speeds vary, BUT on average move 115-197 ft/sec (35-60 m/sec).
How many miles can a commercial jetliner flying at 253 meters per second travel in 6 hours?
1 min = 60 sec 1 hour = 60 min = 60 × 60 sec = 3600 sec 1,609.344 m = 1 mile (exactly) It will travel: Distance = speed × time = 253 m/s × 6 hours = 253 m/s × 6 × 3600 s = 5,464,800 m = 5,464,800 ÷ 1,609.344 miles ≈ 3,395.70 miles.
How do you write a c program to convert time in sec to time?
main() { int sec=00,min=00,hr=00; printf("Enter time in seconds"); scanf("%d",&sec); if (sec<60) printf("%d :%d : %d",hr,min,sec); else if(sec>=60) min=int(sec/60); sec=int(sec%60); printf("%d: %d : %d",hr,min,sec); else if (sec>=3600) min=int(sec/60); sec=int(sec/60) hr=int(min/60); printf("%d : %d : %d",hr,sec,min); }
If you travel 55 miles per hour how many minutes will it take to travel one mile?
1 mi / 55 MPH = 0.018 hr * 60 min / 1 hr = 1.09 min * 60 sec / 1 min = 1 min 5.5 sec
How do you convert hr into sec?
Hr/60 mins/60 sec
How many min are is a sec?
1 min = 60 sec Hence 1 sec = 1/60 min
How long does it take to travel 200 miles at 450 miles per hour?
To travel 200 miles at 450 mph takes 26 min 40 sec. time = distance / speed = 200 miles / (450 miles / hour) = 4/9 hour ≈ 0.444 hour 1 hour = 60 min → 4/9 hour = 4/9 × 60 min = 26 2/3 min ≈ 26.667 min 1 min = 60 sec → 2/3 min = 2/3 × 60 sec = 40 sec
