D. A bimetallic strip bends so that the steel is on the outside curve.
Answer:
Angle of refraction
Explanation:
The incident ray is the ray before it reaches the surface.
The refracted ray is the ray after it reaches the surface.
n₁ is called the index of incidence.
n₂ is called the index of refraction.
θ₁ is called the angle of incidence.
θ₂ is called the angle of refraction.
They are related by Snell's law:
n₁ sin θ₁ = n₂ sin θ₂
Answer:
(a) 41.75m/s
(b) 4.26s
Explanation:
Let:
Distance, D = 89m
Gravity,
= 9.8 m/
Initial Velocity,
= 0m/s
Final Velocity,
= ?
Time Taken,
= ?
With the distance formula, which is
D =
+ 
and by substituting what we already know, we have:
89 =
×9.8×
With the equation above, we can solve for
:

Now that we have solved
, we can use the following velocity formula to solve for
:
, where
is also equals to
, so we have

By substituting
,
, and
,
We have:

Answer:
carbon + oxygen → carbon dioxide
Answer:
it was "The light bends because it changes speed." for me i took the test
Explanation:
i show the thing. i hope this helps
