Answer:
degree
Explanation:
given data:
accoding to the snell's law
where n1 is refracting index of air = 1
n2 is refracting index of glass = 1.55
putting all value to get angle mad by incident ray with normal
degree
Answer:
a current will be induced.
Explanation:
Answer: Sublimation I think.
Explanation:
In order to answer this exercise you need to use the formulas
S = Vo*t + (1/2)*a*t^2
Vf = Vo + at
The data will be given as
Vf = final velocity = ?
Vo = initial velocity = 1.4 m/s
a = acceleration = 0.20 m/s^2
s = displacement = 100m
And now you do the following:
100 = 1.4t + (1/2)*0.2*t^2
t = 25.388s
and
Vf = 1.4 + 0.2(25.388)
Vf = 6.5 m/s
So the answer you are looking for is 6.5 m/s
