Calculating Velocity and Direction Using the Doppler Effect

AI Thread Summary
The discussion focuses on calculating the velocity and direction of a moving object using the Doppler Effect, specifically in the context of sonar technology. An engineer sends a sonar ping at a frequency of 3.75 MHz, and receives a returning frequency of 3.80 MHz, indicating the object is moving. The Doppler Effect equation is essential for solving this problem, as it relates the change in frequency to the velocity of the object. The direction of the object's movement can be inferred from the increase in frequency, suggesting it is approaching the listening station. Understanding these principles is crucial for accurately determining both the speed and direction of the submarine.

Homework Statement



An engineer at an underwater military station listens for submarines by sending an ultrasound sonar ping
that has a frequency of 3.75 MHz.

A second ping returns with a frequency of 3.80 MHz, indicating that the object is now moving. What is the
object’s velocity? In which direction is it moving relative to the listening station? Hint: The direction of sound
reverses after the sound reflects off the moving object.
It uses the doppler effect equation. simple yet detailed explanations will be good

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
