Calculating the Speed of Light Around the Earth in One Day

AI Thread Summary
To calculate how many times a light beam can travel around the Earth in one day, first determine the circumference of the Earth, which is approximately 40,075 km. Knowing the speed of light is 299,800,000 m/s, calculate the distance light travels in one day, which is about 25,902,240,000,000 meters. Dividing this distance by the Earth's circumference gives the number of complete trips a light beam can make around the planet in 24 hours. This approach effectively combines basic physics concepts with practical application in problem-solving.

Speed of light...question

I've just started physics and I'm having difficulty with this problem.I'd really appreciate some help with how to go about doing it!Thanks!

'The speed of light is 299800000 m/s. How many times could a light beam
travel around the Earth in one day (the radius of the Earth is 6370 km)'

Do I need to get the circumference of the Earth first?
 
Physics news on Phys.org
yup get the circumference and distance covered by light in a day
 
will try that!thanks!
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
