Answer:

**Answer:**

15 m/s

**Explanation:**

We know that where f = frequency & d = wavelength .

So here.

Wavelength = 5 m

Frequency = 3 s⁻¹

Hence Speed = 5 * 3 = 15 m/s

Mudflows composed of soil, volcanic debris, and water can occur as the result of an explosive volcanic eruption. What are these mudflows called?

Determine whether or not each of the following statement is true. If a statement is true, prove it. If the statement is false, provide a counterexample and explain how it constitutes a counterexample. Diagrams can be useful in explaining such things. If the electric potential in a certain region of space is constant, then the charge enclosed by any closed surface completely contained within that region is zero.

A standing wave of the third overtone is induced in a stopped pipe, 2.5 m long. The speed of sound is The frequency of the sound produced by the pipe, in SI units, is closest to:

Which one A, B, C, D or the last one?

A shot-putter exerts an unbalanced force of 128 N on a shot giving it an acceleration of 19m/s2. What is the mass of the shot?

The **wavelength **of the **light **passing through the slit is **214** nm.

The **wavelength **is the **distance **between identical **points **in the adjacent cycles of a **waveform**.

Given that the **separation **between two slits **d **is **3.00 × 10^-5 **m and the **distance **from the **slit **to screen **r **is **2 **m. The **distance **from the **central** spot to fringe **s **is **10.0 **m and the **bright **bands of the spectrum **m **are **7 **for the seventh bright fringe.

The **wavelength **of the **light **passing through the slit is calculated as given below.

Hence we can conclude that the **wavelength **of the **light **passing through the slit is **214** nm.

To know more about the **wavelength**, follow the link given below.

To solve this problem, the concepts related to destructive and constructive Interference of light spot and dark spot are necessary.

By definition in the principle of superposition, light interference is defined as

Where,

d = Separation of the two slits

R = Distance from slit to screen

m= Any integer, which represents the repetition of the spectrum. The order of m equal to 1,2,3,4,5 represent bright bands and the order of m equal to 1.5,2.5,3.5 represent the dark bands.

Y = Distance from central spot to fringe.

Re-arrange the equation to find \lambda we have that

Our values are gives according the problem as,

m = 7 (The seventh bright fringe)

R = 2m

Therefore the wavelength of the light passing through the slits is 214nm

Para resolver este problema es necesario aplicar los conceptos de Fuerza, dados en la segunda Ley de Newton y el concepto de Trabajo, como expresión de la fuerza necesaria para realizar una actividad en una distancia determinada.

El trabajo se define como

W = F*d

Where,

F = Force

d = Distance

At the same time we have that the Force by second's Newton law is equal to

F = mg

Where,

m = mass

g = Gravitational acceleration

PART A) Using our values and replacing we have that

PART B) Using Newton's Second law we have that,

**Answer:**

The environment is warmed by the light throughout the day, such that the temperature increases. The weather is decreasing and the temperature decreases in the night as the sun falls. There was a misunderstanding. Thanks to the density, the atmosphere becomes densest on the earth. The air becomes colder and colder when you move up.

**Explanation:**

**Answer is above**

**Hope this helps.**

**Answer:**

The acceleration of the mower will be "**4.7 m/s²**".

**Explanation:**

Balance of vertical force will be:

⇒

For wheel to take off at A,

⇒

Hence,

Balancing moments about G will be:

⇒

As we know,

**Force**, F =

On putting the values, we get

⇒ =

⇒ =

Now,

**Acceleration**, a =

⇒ =

⇒ =

(b) If each holds one end of a rope, and the man pulls on the rope so that he moves 1.3 m, how far from the woman will he be now?

m

(c) How far will the man have moved when he collides with the woman?

m

**Answer:**

Given that

m₁ = 50 kg

m₂=80 kg

d= 12 m

a)

We know that center of mass given as

X = (x₁m₁+x₂m₂)/(m₁+m₂)

Lets take distance of CM from woman is X

So now by putting the value

X = (0 x 50+12 x 80)/(50+80)

**x=7.38 m**

b)

There is no any external force so the CM will not move.

So we can say that

x₁m₁+x₂m₂ = 0

50(x) - 80(1.3)=0

x=2.08

So the distance move by woman d=12-2.08-1.3=8.62 m

**d=8.62 m**

c) lets take distance move by man is x

50 (x) - 80 (12-x) =0

x=7.38

So the distance move by woman d=12-7.38

**d=4.62 m**
