AI Thread Summary
To convert the spaceship's speed of 12,400 miles per hour to light-years per century, first recognize that a light-year is the distance light travels in one year at 186,000 miles per second. The conversion involves changing miles per hour to light-years, then adjusting for the time span of a century, which is 100 years. Some participants express confusion over the conversion process and seek clarification on the steps involved. The discussion emphasizes the importance of proper unit conversion and understanding the relationship between speed, distance, and time. Accurate calculations are crucial for arriving at the correct answer.

Homework Statement


A certain spaceship has a speed of 12400 mi/hr. What is its speed in light-years/century? A light-year is the distance that light travels in one year with a speed of 186,000 mi/s.

Homework Equations


A light-year is the distance that light travels in one year with a speed of 186,000 mi/s.


The Attempt at a Solution


I'm having some trouble figuring out how to do this problem. The homework is submitted online so I can't tell if I'm doing the problem completley wrong or if my answer is off by a little bit. Can anyone help me figure this out? Don't you just have to convert mph to light years and then multiply that by how much time is in a century?

no attempt, no help!
 
by the way its nothing different than converting the given speed to centimeter/nanosecond. simple conversion.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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}...
