Answer:
Greater than
Explanation:
The Wavelength will be higher than what will be heard without any motion on the boat due to the Doppler Effect, which is the change in the frequency of a sound wave whenever there's a relative motion between the source of the wave and observer. The amount of shift in frequency depends on the speed of the source towards the observer; the higher the velocity of the source, the higher the shift.
Answer:
Part a)
Part b)
Part c)
v = 100 m/s
Part d)
since wave is moving in +x direction
so here the sign must be negative
so complete wave equation is
Explanation:
As we know that the wave equation is given as
here we know that
= maximum displacement of the particle
Part a)
maximum displacement = amplitude
so here we know that
Part b)
k =
here we know that length of the string is 3 m
it consist of 3 loops
so we will have
so we have
Part c)
v = wave speed
v = 100 m/s
Part d)
since wave is moving in +x direction
so here the sign must be negative
so complete wave equation is
It's B inertia if I remember correctly you can also rule out A,S and D so...
Answer:
Reactance of the capacitor is 0.01 ohms.
Explanation:
It is given that,
Capacitance of the capacitor is 0.5 F
Peak voltage of the battery is 2 V
Angular frequency is 200 rad/s
We need to find the capacitive reactance. The capacitive reactance is due to the capacitor in the circuit. It is given by :
So, the reactance is 0.01 ohms.
