Answer:
d) y(x,t) = (10.5 mm)cos(172rad?m?1 x ?2730rad?s?1t)
Answer:
The correct option is b
Explanation:
From the question we are told that
The resistance of the first resistor is
The resistance of the second resistor is
The capacitive reactance of the first capacitor is
The capacitive reactance of the first capacitor is
Generally given that the resistors are connected in parallel , their equivalent resistance is
=>
=>
Generally given that the capacitors are connected in parallel , their equivalent capacitive reactance is
=>
=>
Hence the impedance of the circuit is
=>
Generally from the impedance equation , the total used resistance is
<h3><u>Answer;</u></h3>
Transmission
<h3><u>Explanation;</u></h3>
- <em><u>Light waves are types of waves that are electromagnetic waves, meaning they do not require material medium for transmission. </u></em>Light is transmitted as a transverse wave such that the vibration of particles is perpendicular to the direction of wave motion.
- <em><u>A material medium enables the transmission of a wave by the vibration of particles, atoms or molecules. </u></em>The vibration of particles in a medium helps in the transmission of a wave such that energy is transferred from one point to another due to the disturbance caused by the wave.
Answer:
1875 m west
Explanation:
Take east to be the positive direction. Given:
v₀ = -25 m/s
a = 0 m/s² (constant velocity)
t = 75 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (-25 m/s) (75 s) + ½ (0 m/s²) (75 s)²
Δx = -1875 m
