Answer:
Yes it would
Explanation:
As the arrow and the orange are in the same position initially, vertically speaking. They are also subjected to the same gravitational acceleration g only in the vertical direction. They also start their motion at the same time. So their equation of motion can be written as
Where h is the initial height of both of them. Since their g, h, and t are the same, their vertical position must be the same at the same time. As the arrows progress horizontally, it would hit the orange.
Answer:
Wavelength of sound in the pipe is 6.0 m
Explanation:
As we know that closed pipe is given to us so here at open end it will form antinode while at closed end it will form Node
Here we know that in closed pipes on odd harmonics will exist
so here for third harmonic we have
where L = length of the pipe
so we have
Answer:
Explanation:
Given that,
Magnetic field of 0.24T
B = 0.24T
Field perpendicular to plane i.e 90°
Rate of decrease of length of side of square is 5.4cm/s
dL/dt = 5.4cm/s = 0.054m/s
Since it is decreasing
Then, dL/dt = -0.054m/s
When L is 14cm, what is the EMF induced?
L = 14cm = 0.14m
EMF is give as
ε = - dΦ/dt
Where flux is given as
Φ = BA
Where A is the area of the square
A = L²
Then, Φ = BL²
Substituting this into the EMF
ε = - dΦ/dt
ε = - d(BL²)/dt
B is constant
ε = - Bd(L²)/dt
ε = -2BL dL/dr
ε = -2 × 0.24 × 0.14 × -0.054
ε = 3.63 × 10^-3 V
ε = 3.63mV
I think some of the given is wrong, 10 ms-1, think it is only 10 s-1 which represents the frequency of the wave, and can be use to solve for the wavelength of the sound wave given
wavelength = wave speed / frequency
wavelength = 1500 m/s / 10 s-1
wavelength = 150 m ( 100 cm / 1 m ) = 15000 cm
