Answer the amplitude part of the questions in 7, 8, & 9
erastova [34]
I actually believe for the first question, it would be complete destructive interference as the amplitude and the approximate wavelength for each are the same and will completely or entirely cancel out, rather than simply decreasing or lowering the amplitude as in the bottom question.

The amplitude for the first will be 0, as the 2 waves will cancel each other out. The amplitude of the second, will be 3x, I believe, assuming the amplitude of the first is 2x and the second is 1x, in a constructive interference, I believe the amplitudes would add up.

Likewise for the bottom, I believe you would be subtracting the supposed amplitude of the first which is 2x from 1x which would be 1x.

While filming an intense action sequence for the next James Bond movie, a controlled explosion detonates 1.3 km away from the ac
brilliants [131]

To solve this problem we must basically resort to the kinematic equations of movement. For which speed is defined as the distance traveled in a given time. Mathematically this can be expressed as

v = \frac{d}{t}

Where

d = Distance

t = time

For which clearing the time we will have the expression

t = \frac{d}{v}

Since we have two 'fluids' in which the sound travels at different speeds we will have that for the rock the time elapsed to feel the explosion will be:

t = \frac{1300m}{3000m/s}

t = 0.433s

In the case of the atmosphere -composite of air- the average speed of sound is 343m / s, therefore it will take

t = \frac{1300m}{343m/s}

t = 3.79s

The total difference between the two times would be

\Delta t = 3.79s-0.433s

\Delta t = 3.357s

Therefore 3.357s will pass between when they feel the explosion and when they hear it

Resistivity measurements on the leaves of corn plants are a good way to assess stress and overall health. The leaf of a corn pla
Gnoma [55]

Answer:

Part a)

\rho = 52.9 ohm- m

Part b)

the resistivity of corn plant is grater than the resistivity of muscle tissue in the human

Explanation:

Part a)

As we know the formula of resistance is given as

R = \rho \frac{L}{A}

here we know that

\rho = \frac{RA}{L}

here we have

R = 2.3 M ohm

L = 20 cm

Area = (0.023)(0.20 \times 10^{-3})

Area = 4.6 \times 10^{-6} m^2

now we have

\rho = \frac{(2.3 \times 10^6)(4.6 \times 10^{-6})}{0.20}

\rho = 52.9 ohm- m

Part b)

Resistivity of mucle tissue of human is is ranging from 15 ohm-m to 50 ohm m so here we can say that

the resistivity of corn plant is grater than the resistivity of muscle tissue in the human
