Is the energy of a wave is calculated by squaring the frequency of the wave?

1 answer:

5 0

Nope.
Energy is directly proportional to frequency. and when you calculate energy, you multiply frequency with a constant number called "Planck's Constant"

E = hf

Hope this helps!

A fighter plane is flying overhead at mach 1.50. What angle does the wave front of the shock wave produced make relative to the

olga2289 [7]

Answer:

θ = 41.80°

Explanation:

Given that

Mach number M= 1.5

We know that

M = u/c

Where c is the velocity of sound and u is the speed of plane

c= 340 m/s

u = 1.5 x 340 m/s

u = 510 m/s

We know that

$sin\theta =\dfrac{c}{u}$

Now by putting the values

$sin\theta =\dfrac{c}{u}$

$sin\theta =\dfrac{340}{510}$

θ = 41.80°

So the angle will be 41.80°.

What is the voltage, V2, in units of Volts, across resistor R2 in the circuit shown below where VS = 4V, R1 = 14 Ohms and R2 = 3

svetlana [45]

<h2>Correct answer:</h2>

$\boxed{v_{out}=2,85V}$

<h2>Explanation:</h2>

We can use voltage divider to solve this problem that is defined as the passive linear circuit producing an output voltage $v_{out}$ that is a fraction of its input voltage $v_{in}$ . So we can use the formula:

$v_{out}=\frac{R_{2}}{R_{1}+R_{2}}v_{in}, \ where \ v_{in}=v_{s}=4V \\ \\ \therefore v_{out}=\frac{35}{14+35}(4) \\ \\ \therefore v_{out}=2,85V$
