Answer: C. 20J
Explanation: im pretty sure sorry if im wrong :(
Answer:
t = 94.17 nm
Explanation:
given,
refractive index = n = 1.50
wavelength of light = 565 nm
minimum thickness, t = ?
using formula
where value of m lies
m = 0 , 1 , 2 ...
form minimum thickness m = 0
t = 94.17 nm
minimum thickness of the film is equal to 94.17 nm
Answer:
A_1 = 0.0135 m2
Explanation:
GIVEN DATA:
mass of SECOND truck m2 =2500 kg
mass of FIRST truck m1 = 25 lb = 11.33kg
Area A2 = 3 m2
according to the pascal's law, pressure at one point is equal to pressure exerted on the other side, therefore we have
we know that
A_1 = 0.0135 m2
