The biggest star in our solar system is the sun. It's also the smallest one, because it's the only one.

Anettt [7]

Answer:

The average current is 19.567 A

Solution:

As per the question:

Charge, Q = $8.0\times 10^{- 4}\ C$

Time, t = $35\times 10^{- 6}\ s$

Now,

We know that current is constituted by the rate of transfer of the charge per unit time. Thus we can write:

I = $\frac{Q}{t}$ (1)

Now, the charge that was transferred is 86 % of the original value.

Therefore,

We replace Q by 0.86Q in eqn (1):

I = $\frac{0.86\times 8.0\times 10^{- 4}}{35\times 10^{- 6}} = 19.657\ A$

Wave travelling along right with speed of 0. 5 m/s time 4 second point p

Soloha48 [4]

The wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.

<h3>What is the speed of wave?</h3>

Speed of wave is the rate by which the wave travels. It can be described as the distance cover by the crest or thrust of it per unit of time. It can be calculated with the following formula,

$v=f\times\lambda$

Here, (f) is the frequency and (λ) is the wavelength.

The frequency is inverse of time. Thus, the value of frequency in time t is,

$f=\dfrac{1}{t}\\f=\dfrac{1}{4}\\f=0.25$

The speed of the wave is 0.5 m/s. Put the values in the formula,

$v=f\times\lambda\\0.5=0.25\times\lambda\\\lambda=\dfrac{0.5}{0.25}\\\lambda=2$

Thus, the wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.

HELP ASAP!!! 100 points!!!!!!!!!

Zepler [3.9K]

Answer:

Shown from explanation.

Explanation:

The resonant frequency is related by the formula;

Fo= 1/2π√(K/M)

Where Fo is resonant frequency

M is mass

K is the spring constant

From the expression above;

When K is increased frequency would increases since frequency is directly proportional to spring constant.

Similarly when the mass is increased the frequency decreases since frequency is inversely proportional to the mass.

Amplitude is a property of a wave and so the frequency stays same.
