Answer:
I am sure the awnser to this is
B. vibrate
Answer:
It is an open circuit as the current isn't flowing through the circuit as the wires aren't connected
Answer:
if bother parents have brown eyes but they carry the allele for blue eyes a quarter of the kids will have blue eyes and three quarters will have brown eyes. hope this help I'm sorry if it doesn't.
Answer:
The phase change of
can be theoretically understood as follows:
For transmission or propagation of waves between media the wave motion should maintain a principle of continuity meaning that the wave function at the interface should be continuous and diffrentiable at the interface.
At the point of incidence there are 2 types of waves reflected wave and the incident wave. Now the principle of continuity dictates that the sum of the phases of the above 2 waves should be same as that of transmitted wave. If we use these relations we notice that the reflected wave shall either change it's phase by
or will not change it's phase depending on the relationship between the refractive indices of the incident and the reflecting medium. For a solid boundary a phase change of
occurs.
Answer:
0.73 W/m²
0.2522 W/m²
Explanation:
= Unpolarized light = 1.46 W/m²
= Analyzer angle = 54°
Light through first filter

The intensity of the light leaving the polarizer is 0.73 W/m²
After passing through analyzer

The intensity of the light that reaches the photocell is 0.2522 W/m²
