Two carts each 12 cm long travel toward each other on a frictionless air glider track. The first cart on the left has an initial velocity of 18 cm/s toward the other cart that is stationary. The carts then collide. The cart on the left has a new velocity of -4cm/s and the stationary cart now has...

I don;t get it? How am I meant to solve for something that has two unknown variables? the theta and the m value?

d sin theta = m lambda?

Yeah... still not hitting any switches, sorry, lol. How are we meant to find the number of orders?

A diffraction grating with 600 lines/mm is illuminated with light of wavelength 500nm. A very wide viewing screen is 2.0m behind the grating. b.) How many bright fringes can be seen on the screen. MY ATTEMPT: i worked out the angular separation between bright fringes to be 0.305 rad (i...

A violinist places her finger so that the vibrating section of a 1.0g/m string has a length of 30cm, then she draws her bow across it. A listener nearby in a 20 degrees celsius room (speed of sound at this temperature in air is 343 m/s) hears a note with a wavelength of 40 cm. What is the...

If i used f = 1/2L Sqrt (Tension/Linear Density) wouldn't I get the fundamental frequency? how are we meant to know if the frequency i calculated is the fundamental frequency?

Hello Greg. I got the frequency in air to be 857.5 from the equation v = f lambda Is the frequency of the sound wave in the air the same as the frequency in the string? If yes, how is it that since some of the energy is transmitted to the the new medium (air in this case) and some...

would it be 65Hz?

1.) A string, stretched between two fixed posts, forms standing-wave resonances at 325Hz and 390Hz. What is the largest possible value of its fundamental frequency? I have no idea on how to solve this problem, any assistance would be greatly appreciated.

Hi all, quick problem I'm having trouble with. Oil explorers set off explosives to make louds sounds, then listens for the echoes from underground oil deposits. Geologists suspect that there is oil under 500-m deep lake physics. It's known that lake physics is carved out of a granite basin...

ok thanks for that, i understand it now. since you're here I might as well get help with another quesiton: Oil explorers set off explosives to make louds sounds, then listens for the echoes from underground oil deposits. Geologists suspect that there is oil under 500-m deep lake physics. It's...

Hi all, just a question I am having trouble with 1.) You're watching a carpenter pound a nail. He hits the nail twice a second, but you hear the sound of the strike when his hammer is fully raised. What is the minimum distance from you to the carpenter? assume the air temperature is 20...

haha i was so sure i was correct before; i used your method and got 20.60 m/s for the initial velocity in the x-direction, can you confirm?
