That depends on a number of things that we don't know because you haven't told us.
If any of the things on this list changes, then the answer to the question changes:
-- What is "it" ?
-- Was it dropped, thrown, fired, or launched ?
-- From what height above the ground ?
-- With what speed ?
-- In what direction ?
-- What is the acceleration of gravity where this took place ?
-- Did any drag act on it, due to liquid or gas, before it hit the ground ?
<span>The advantage of using an electromagnet rather than a regular magnet is that an electromagnet is stronger and you can control the power of the magnet. </span>
Answer:
The angle of refraction is 37°.
Explanation:
let n1 be the refractive index of glass and n2 = 1.0 be the refraction index of air, θ be the angle of incidence , ∅ be the angle of refraction.
then, according to Snell's law:
n1×sin(∅) = n2×sin(θ)
sin(∅) = n2×sin(θ)/n1
= (1.0)(sin(71°))/(1.56)
= 0.606101651
∅ = 37°
Therefore, the angle of refraction is 37°.
