AI Thread Summary
The discussion centers on calculating the time it takes for a radar signal to reflect off an island 1500 meters away from a ship. The formula used is t = s/v, where the signal's speed is the speed of light (approximately 3 x 10^8 m/s). The total distance the signal travels is doubled to 3000 meters, accounting for the round trip to the island and back. The calculated time for the signal to be sent and reflected is 10^-5 seconds. This demonstrates the importance of considering the full distance when calculating reflection times.

Homework Statement



the radar on a ship sends out a signal which reflects off a rocky island 1500m ahead of the ship. how much time passes from the time the signal is sent until the reflection is detected?

2. Homework Equations

t=s/v

3. The Attempt at a Solution

v=c=3.10^8 (m/s)

s=2.1500=3000 (m)

t=3000/3.10^8= 10^-5 (s)
 
thanks!
but y did u times by 2?
 
Because the signal is reflected, so it must travel 2 times the distant between the island and the ship (sent, reach the island and come back)
 
ok great thanks!

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}...

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...
