There must be a conducting wire and electromotive force or free electrons
Answer:
Time=3.1 seconds
Explanation:
Given data
Distance S=20 m
Velocity v=10×Sin60°
To find
Time after release
Solution
From equation of simple motion we know that
Using the convention that down is positive then
Apply Quadratic formula to solve t
Ignoring the -ve root then we have
t=3.1 seconds
To solve this there is this website that I found that helps
I am in middle school so I have no idea how to solve this
but
this website may help considering u are in high school and u
(hopefully mind u)
know how to solve this
so to get there u google
"whats impact speed"
and click on the first thing there the website is ehow
You need to use snell’s law in this problem. N1sin (theta) = n2sim (theta)
N1 = index of oil
N2 = index of glass
If you already have the numbers, include it in this
equation:
N1.sin (90deg) = N2.sin (critical angle) (note sine (90deg)
= 1)
