AI Thread Summary
To determine how many more wavelengths occur in air than in water at 10°C, the speed of sound in air must be known, which is approximately 1235 km/hour at that temperature. The wavelength in water can be calculated using the formula: wavelength = speed of sound / frequency, resulting in a wavelength of approximately 10.44 meters in water. For air, the wavelength can be calculated similarly, leading to a longer wavelength due to the lower speed of sound in air. The ratio of wavelengths can then be found by dividing the wavelength in air by the wavelength in water. This calculation reveals that sound waves occur more frequently in air than in water at the specified conditions.

Please solve showing all work asap thanks sooo much

How many times more wavelengths occur in air than in water for an air temperature of 10 degrees Celsius if the speed of sound in water id 5220 km/hour and the frequency of sound is 500 Hz.

Grade 11, thanks so much please ASAP

We are not going to do your homework for you. Well maybe if you pay as much as... no... no we won't!

Can you find the wavelength of that sound in water?
What do you need to know to find the same thing in the air?
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

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...
