AI Thread Summary
To solve the homework question on wave period, frequency, and velocity, it's essential to understand the definitions and units of these terms. The period is the time it takes for one complete wave cycle, measured in seconds. Frequency is the number of waves that pass a point in one second, expressed in hertz (Hz), while velocity refers to the speed of the waves, typically measured in meters per second (m/s). Given that two waves arrive every five seconds, the period is 5 seconds, the frequency is 0.4 Hz, and the velocity can be calculated using the wave separation distance. Understanding these concepts is crucial for accurately answering the questions posed.

Here is the Question.

You observe water waves coming to shoreon a large lake. You obseve that every five seconds, two more waves come in, and that the waves are seperatedby four meters.

a) What is the period of the waves?
b) What is the frequency of the waves?
c) What is the velocity of the waves?

Where do I start?

As a start, you need to make sure you understand the meaning of the terms period, frequency, and velocity. Can you tell us what they mean and what their units of measurement are?
 

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...
