Homework Equations
The Attempt at a Solution
16 and 17--
16--
U = C_v 300-275 but how do i find C_v
17 ---is zero from properties of adiabatic process.
23 How am I supposed to know its 4 without memorizing the resistance
i know R = rho L/a but I would have to memorize rho.
6 ---it has to be 3 because of maximum magnitude = 718 and 43----Same as 23 ---
I use v= at + v_o to find half of time in air above horizontal from starting point
for both balls then
used x= 0.5 g t^2 to find the rest of the time and then figured out ratio
but this way is very computationally intensive is there a better way.
30-- am I supposed to know an equation for n(lambda)
19--- same as 23
29-- the frequency stays the same but why?
