Hey guys, there's something I've been confused about when looking at circular motion. When does an object have just centripetal acceleration as the acceleration of the object, if ever. I think that the acceleration vector is between the centripetal and tangential acceleration when an objects...

Water Bottle Flipping Fidget Spinner on Sloped Surface

Well I am pretty sure that the kinetic energy stays the same because in this case the velocity vector and energy make a ninety degree angle so no work is done, but I am lost about angular momentum. It could decrease maybe if the torque is clockwise while the ship is going in a counterclockwise...

Do you think that I could do distance over time to find wave speed. Like the wave traveled 4 meters in 2 seconds so its speed is 2 m/s and then if the frequency doubles from .5 to 1, the period is one and the wavelength would be 2m?

I took a screenshot of the answer choices...will that help?

Gotcha. I attached a picture of the question :)

Oh okay, thank you!

Okay well I'm stuck on this one. I know that lamba times frequency is wave speed and 1/f is period. I think that the wavelength of the wave is four but what is the frequency? (1/2)? Would I multiply 4*1/2 to get 2 m/s as the wave speed and then if the frequency doubles to .25, the wavelength be...
