Answer:
4.26
Explanation:
The wavelength λ is given by:
Phase constant (β) = 2π/λ
βl = 2π/λ × l
l = 2 cm = 0.02 m
βl = 2π/0.0625 × 0.02=2.01 rad = 115.3°
1 rad = 180/π degrees
Answer:
- resistance (ohms) will stay the same
- amps will double
Explanation:
Assuming linear circuit elements being operated within their ratings, ...
- resistance (ohms) will stay the same
- amps will double
For constant resistance, current is proportional to voltage. For a circuit in which resistance is not affected by voltage or temperature, the resistance will stay the same when voltage increases. Then the current will be proportional to the voltage.

<em>Additional comments</em>
In some circuits, resistance is a function of temperature. An incandescent light, for example, increases its resistance as its temperature goes up. When voltage is increased, resistance is increased according to the increased power dissipation. Current increases, but not proportionally to voltage.
Some other devices also exhibit this effect, but their resistance is designed to increase to a high enough level that overall circuit current actually decreases when voltage exceeds a certain threshold.
