Answer:
24.4 m
Explanation:
sin 30 = 12.2 / x
x = 12.2 / sin 30 = 24.4 m
Weak nuclear force is weaker than the strong nuclear force with a smaller range than the electromagnetic force.
It acts between fermions with spin 1/2 basically quarks and leptons. It has a range of 10⁻¹⁸ meters.
Option 1 is incorrect. It is stronger than the gravitational force.
Option 2 is incorrect. It is weaker than the electromagnetic force.
Option 3 is incorrect. It has a smaller range than the strong nuclear force.
Answer:
Explanation:
Let the critical angle be C .
sinC = 1 / μ where μ is index of refraction .
sinC = 1 /1.2
= .833
C = 56°
Then angle of refraction r = 90 - 56 = 34 ( see the image in attached file )
sin i / sinr = 1.2 , i is angle of incidence
sini = 1.2 x sinr = 1.2 x sin 34 = .67
i = 42°.
Answer:
a) r=4.24cm d=1 cm
b)
Explanation:
The capacitance depends only of the geometry of the capacitor so to design in this case knowing the Voltage and the electric field
The distance must be the separation the r distance can be find also using
But now don't know the charge these plates can hold yet so
a).
d=0.01m
b).
