This is not a physics question. Just hoping for advice for any people who taken this course in high school. My school is a block schedule so I take AP physics B and AP physics C in one year. Currently, the first semester i am making 23% on tests and the highest was a 40%. I am one of the top...

That is what i was trying to ask. The question is like that. I ask some people and they say it is missing a variable,.

Homework Statement 1. If v is constant, how does f change if λ quadruples? 2. c is equal to 3x10^8 m/s. What is the value of n if v equals 2.25 x 10^8 m/s 3. If n2 is greater than n1, is Ө1 greater than, less than, or equal to Ө2? Prove using third equation. 4. Assuming Ө2 is 90 degrees...

Homework Statement Given v0= 0 m/s, xo=0 m and t= 10s, use the equation below together to find Xf Homework Equations x=xo+volt+(1/2)at^2 vf^2=vo^2+2a(xf-xi) The Attempt at a Solution vf=at xf-1/2at^2 vf=2axf so then, plug in t=10 and vf=10a xf=50a ... I don't know...

The equations used are: 1)ΣF=ma 2)fk = μkN 3)fs ≤ μsN 4)Fs = - kx Here are the questions: 1. If ΣF is 10N and a=1 m/s^2, find m using the first equation 2. Given ΣF = fk, m=250 kg, μk=0.2, and N = 10m, find a. 3. ΣF=T-10m, but a=0 m/s^2. Use the first equation to find m in terms of T...
