Answer:
4)-4/5
Step-by-step explanation:
y=-4/5x+-3
This is in slope intercept form
y = mx+b
The slope is -4/5 and the y intercept is -3
Additional information to complete the question:
How long does it take for a short pulse of light to travel from one end of the glass to the other?
Express your answer in terms of some or all of the variables f and L. Use the numeric value given for n in the introduction.
T = ___________ s
Answer:
Step-by-step explanation:
Given:
Thickness og glass = L
Index of refraction n=1.5
Frequency = f
λ(air)
λ(glass) = λ(air) / n
=
=
=
V(glass) = fλ(glass)
First turn the statement into an equation:
3X=12+(X+26). You can combine the 12+26 and now you should have 3X=X+38. Subtract an X from both sides of the equation (2X=38) now finally divide by 2 to find X. X=19
Answer:
Step-by-step explanation:
the given equation is
from the multiplication rules we know that
so for the given equation changing the sidn of division to multiplication
the equation becomes
a cancels out from both numerator and denominator
so it becomes
which is the answer
