oh thankyouu!

Homework Statement a certain young's apparatus has slits 0.12 mm apart. the screen is at a distance of 0.80 m. the third bright line to one side of the centre in the resulting interference pattern is displaced 9.0mm from the central line. calculate the wavelength of the light used. What...

not sure .. considering it didn't say I'm going to assume that it's stationary.

It's the mass of an oil drop and I am looking for the charge of it. That's basically all the info given to me, and the question isn't really given to me in a word question, it just says to find the charge of the drop with info in chart provided.

Homework Statement Find the charge find the charge: mass : 3.6*10^-12 kg electric potential difference: 250.4 V parallel plates are 0.41 cm apart PLEASE DO NOT link me a wikipedia page.. or give me a one sentance explanation of something unrelated to this question Just need to know how to...

when forces are balanced, the mass will move at a constant velocity.

Okay thanks! Well our lab asks us when it is in dynamic equilibrium :S do I should write that there is home?

:$ Sorry I'm kind of lost.. So when IS it in dynamic equilibrium? it's supposed to be when the two forces acting on it are equal no? so gravity=force of tension i was geussing.. Thanks!

Can someone just check if these are correct: the amplitude does not affect the period of vibration within a spring because the period will only change if the mass or force constant changes. a mass experiences dynamic equilibrium when the mass is hanging on the spring at its most...

Oh actually we had to find k too :S But thanks again tiny-tim :D

Yeah... But we double checked with other groups and it was relatively the same .. But ideally, If I had the correct information, should both of finding period work ? :S

We calculated the time it takes for the hanging mass attached to the spring To fall and make 10 cycles . So tits 10 cycles in 4.7s

m=100g = 0.1kg g= 9.8 m/s^2 k= 26.6 so when 2π(sqrt(m/k)) =2π(sqrt(0.1/26.6)) 0.39 seconds/cycles t=4.7s cycles=10 so t/cycles= 4.7s/10 =0.47 .. :s

Homework Statement Information provided is: mass of spring, displacement, force of constant, gravity. so basically: m, x, k, and g Determine the relationship between the period and mass so how do i find T? Homework Equations T= seconds/cycles T= 2π(sqrt(m/k)) The Attempt at...

and the questions have yet to end .. a bungee jumper of mass 64.5 kg is standing on a platform 48 m above a river. the length of the unstretched bungee cord is 10.1 m . the force constant of the cord is 65.5 N/m. the jumper falls from rest and just touches the water at a seed of zero. The cord...
