"As you sit in a fishing boat, you notice that 12 waves pass the boat every 45 s. If the distance from one crest to the next is

9.2 m , what is the speed of these waves?"
Physics

Answer:

2.4564 m/s

Explanation:

Number of waves in 1 second

\dfrac{12}{45}=0.267\ Hz

This is the frequency 0.267 Hz

The distance mentioned in the question is the

\lambda = Wavelength = 9.2 m

The speed of wave is

v=f\lambda

\Rightarrow v=0.267\times 9.2

\Rightarrow v=2.4564\ m/s

The speed of the wave is 2.4564 m/s

The coordinates of a bird flying in the xy plane are given by x(t)=αt and y(t)=3.0m−βt2, where α=2.4m/s and β=1.2m/s2. Calculate
yuradex [85]
     The derivative of the function space as a function of time is equal to a function of speed as a function of time.

x(t)=2.4t \\  \frac{x(t)}{t}=t \\ v_{x}(t)=t \\  \\ y(t)=3-1.2\times t^2 \\  \frac{y(t)}{t}=1.2\times2t \\ v_{y}(t)=2.4t
   
     The velocity vector is given by the vector sum of the velocities of  both axes.

v_{R}^2(t)=v_{x}^2(t)+v_{y}^2(t) \\ v_{R}^2(t)=(t)^2+(2.4t)^2 \\ \boxed {v_R(t)=2.6t}

If you notice any mistake in my english, please let me know, because I am not native.

Resistance of a light bulb with 0.33 A of current flowing from a 12V battery?
Sergio039 [100]

Resistance = (voltage) / (current)

Resistance = (12v) / (0.33 A)

Resistance = (12/0.33) ohms

<em>Resistance = 36.4 ohms</em>
