Answer:
F=ma
So we have to find acceleration
V^2-U^2=2as
V=0 ,U=10m/s ,s= 50m
(0)^2-(10)^2=2*50*a
0-100=100*a
-100=100*a
-100/100=a
-1=a
F=ma
F=1000*-1
F= -1000N
Hope this is the right answer
Answer:
1) Total internal reflection
2) Snell's law
Explanation:
As already mentioned in the question, on way of determining the refractive index is to use the idea of total internal reflection. In that case, we measure the critical angle. This is than angle of incidence in the material, for which the angle of refraction is 90°.
n=1/sinC
Alternatively, we could use Snell's law. In this case, we measure the angles of incidence and refraction.
Refractive index= sini/sinr
Answer:
3/4.no because there going in diffrent directions
Explanation:
The loss of species of organisms is due to loss of their habitat.
If you went through a city and cut all the houses down to their
foundations, the people who lived in them would either die or
go somewhere else if they could.
