Answer:
correct answer is the c
Explanation:
The laws of optical geometry are the law of reflection and refraction, in them the relationship between the incident angles and reflected or transmitted by a given surface is established, in these laws it is not specified how the angles should be measured by which they could measure as follows
.- between the beam and the surface
.- between lightning and normal, the most used
Let's check the answers
a) True.
b) True
c) True
We see that the three answers are true, but the answer c involves the other two, so the correct answer is the c
Answer:
9.74 x 10^7 m/s
Explanation:
V = 27000 V
energy of electrons = e x V
K = 1.6 x 10^-19 x 27000 = 43200 x 10^-19 J
Energy = 1/2 m v^2
43200 x 10^-19 = 0.5 x 9.1 x 10^-31 x v^2
v^2 = 9.495 x 10^15
v = 9.74 x 10^7 m/s
Answer:
g=9.64m/s^2.
Explanation:
Gravitational field strength (in other words, gravitational acceleration) is given as follows:g=GMR2g=R2GMwhere G=6.674×10−11m3kg⋅s2G=6.674×10−11kg⋅s2m3 is the gravitational constant, M=5.972×1024kgM=5.972×1024kg is the mass of the Earth, and R=6.371×106m+0.06×106m=6.431×106mR=6.371×106m+0.06×106m=6.431×106m is the distance from the center of the Earth to the required point above the surface (radius plus 60 km).
