    Speed Wave
AI Thread Summary
To calculate the speed of the wave based on a 1-second echo from a holler reflecting off canyon walls 170 meters away, the formula V = D/T is used. Since the sound travels to the walls and back, the total distance is 340 meters (170 meters each way). The time for the round trip is 1 second, so the speed of the wave is 340 meters per second. This calculation confirms that the speed of sound in air is approximately 340 m/s under typical conditions. Understanding these principles is essential for accurately measuring sound wave behavior in various environments.

if an echo is heard one second after the holler and reflects off canyon walls which are a distance of 170 meters away,then what is the speed of the wave?

V = D/T

You have distance and you have time. Just plug in the numbers. Remember you will be working with 2 way distance.
 

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 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
