For this case we have that by definition, the momentum equation is given by:
Where:
m: It is the mass
v: It is the velocity
According to the data we have:
Substituting:
On the other hand, if we clear the variable "mass" we have:
According to the data we have:
Thus, the mass is
Answer:
Answer:
41°
Explanation:
refractive index of glass, n = 1.52
For total internal reflection, the angle of refraction in rarer medium is 90°.
r = 90°
Let the angle of refraction in denser medium, that means in glass is i.
By use of Snell's law
refractive index of rarer medium with respect to denser medium, that means refractive index of air with respect to glass = 1 / n
And
i = 41°
Thus, the angle of incidence should be 41°.
