Help!!

Anna [14]

Compute the work done on the table:

W = Fd = (320 N) (32 m) = 10,240 J

Divide this by the given time duration to get the power output:

P = W/∆t = (10,240 J) / (150 s) ≈ 63.3 W

Diffraction of sound waves is demonstrated when sound waves with a frequency of 1300 Hz from a distant source are diffracted thr

Tresset [83]

Answer:

39.05°

Explanation:

As we know that, the diffraction is the phenomena of bending of light when it passes through an obstacle.

Mathematically,

$dsin\theta=n\lambda$

Here, d is slit width, $\lambda$ is the wavelength, n is the order, $\theta$ is the angle.

Given that, d is 84 cm, n is 2, and the wavelength can be calculated as,

$\lambda=\frac{c}{f}$

Here, c is the speed of sound and f is the frequency of sound wave.

Here, c is 343 m/s and f is 1300 Hz,

Therefore,

$\lambda=\frac{343 m/s}{1300 Hz}\\\lambda=0.264m$

Recall diffraction equation in term of $sin\theta$ .

$sin\theta=\frac{n\lambda}{d}$

Put all the variables.

$sin\theta=\frac{2\times 0.264 m}{84 cm}\\sin\theta=\frac{2\times 0.264 m}{0.84 m}\\\theta=39.05^{\circ}$

Therefore, it is the required angle between the first 2 order of diffraction.

What is the equivalent resistance of a 7ohm resistor and a 93 ohm resistor connected in parallel? PLEASE HELP ASAP

lukranit [14]

When you have several resistors in parallel, their equivalent resistance is the reciprocal of the sum of their individual reciprocals.

When there are only two of them, it gets a lot easier. In that case, their equivalent resistance is equal to

(their product) divided by (their sum).

Equivalent = (7 x 93) / (7 + 93)

Equivalent = (651) / (100)

Equivalent = 6.51 ohms .

Answer:

Follows are the solution to this question:

Explanation:

By checking the value in which we have calculated by performing its differentiation of $\frac{a}{3}t^3+bt$ , the correct form of its integer value is calculating with regard to t, that also provides as expected $at^2+b = F(t)$ .
