Intensity of wave is defined as

I = KA^2

here K = constant

A = amplitude

we can defined intensity by energy per unit area per unit time

So intensity is given by formula

I = \frac{Energy}{Area*time}

So here we can say if` medium properties like density is uniform as well as frequency of wave will not change then energy of wave depends on intensity and intensity of wave directly depends on amplitude

So answer for the above question is Amplitude

Now set the tension to low and wiggle the wrench to create more waves. Can you explain how moving the first point on the string,

Answer:

When the string moves, it creates a very small change in the distance to the next point, th

Explanation:

When the string moves, it creates a very small change in the distance to the next point, this generates a restoring force that tends to push the string back, this small disturbance propagates along the string and is what creates the pulse.

This is similar to what happens when a spring is stretched and a restoring force is generated shaved by the law of shortening.

Area<br>find (a) volume and b) Total surface<br>of hemi shere with diameter<br>28 cm​
AlekseyPX

Answer:

a) Volume = 2/3 \pir³

Volume = 2/3 × 22/7 × 14 × 14 × 14 = 5749.3 cm³

b) Total surface area = 3\pir²

Area = 3 × 22/7 × 14 × 14 = 1848 cm²

Dario, a prep cook at an Italian restaurant, spins a salad spinner and observes that it rotates 20.0 times in 5.00 seconds and t
ziro4ka [17]

Answer:

(a). The acceleration is 8.3 rad/s².

(b). The time is 3.0 sec.

Explanation:

Given that,

Rotation = 20.0 times

Time = 5.00 sec

We need to calculate the angular frequency

Using formula of angular frequency

\omega_{i}=20\times\dfrac{2\pi}{T}

put the value into the formula

\omega_{i}=20\times\dfrac{2\pi}{5.00}

\omega_{i}=8.00\pi

We need to calculate the angular displacement

Using formula of  angular displacement

\theta=6\times2\pi=12\pi

We need to calculate the angular acceleration

Using equation of angular motion

\omega_{f}^2-\omega_{i}^2=2\alpha\times\theta

0-64\pi^2=2\times12\pi\times\alpha

\alpha=-\dfrac{64\pi^2}{24\pi}

\alpha=-8.3\ rad/s^2

Negative sign shows the opposite direction of the motion.

The acceleration is 8.3 rad/s².

We need to calculate the time

Using equation of angular motion

\omega_{f}-\omega_{i}=\alpha\times t

0-8\pi=-8.3t

t=\dfrac{8\pi}{8.3}

t=3.0\ sec

The time is 3.0 sec.

Hence, (a). The acceleration is 8.3 rad/s².

(b). The time is 3.0 sec.
