Echo is a reflection of sound waves.  If the distance is increased, we hear the sound in  more than twice the former time.

The term echo has to do with the reflection of sound waves. We know that when sound waves are reflected, we hear the sound as the echo.

Now, the time that it takes us to hear the echo depends on the distance between the observer and the depth of the well. If the distance is increased, we hear the sound in more than twice the former time.

Two light waves will interfere constructively if the path-length difference between them is a whole number.

The principle of superposition state that, when two or more waves meet at a point, the resultant displacement at that point is equal to the sum of the displacements of the individual waves at that point.

Interference of waves can either be constructive, or destructive.

The two light waves, initially emitted in phase, will interfere constructively with maximum amplitude if the path-length difference between them is a whole number of wavelenght 1λ, 2λ, 3λ, 4λ etc

The equivalent phase differences between the waves will be 2[tex]\pi[/tex] or 360 degrees, 4[tex]\pi[/tex] or 720 degrees, 6[tex]\pi[/tex] 1080 degrees etc

Therefore, the two light waves, initially emitted in phase, will interfere constructively with maximum amplitude if the path-length difference between them is a whole number.

When the measured value of mass M becomes 2 M, the error in the measurement will be 0.00995 kg.

The percentage error is determined from the ratio of the error in meaurement to actual measurement.

Percentage error = (error / measurement) x 100%

Percentage error = (0.005 / 0.743) x 100%

Percentage error = 0.67%

New mass = 2 x 0.743

New mass = 1.486 kg

0.67 = (new error / 1.486) x 100%

0.0067 = new error / 1.486

new error = 0.0067 x 1.486

new error = 0.00995 kg

Thus, when the measured value of mass M becomes 2 M, the error in the measurement will be 0.00995 kg.

Answer: 38% efficiency

Explanation:

Given:
- Mass of box, 500.0kg

- Height lifted, 3.50m

- Force Applied, 10 000N

- Distance applied, 4.50m

Required:

% Efficiency, can be found through formula η = [useful energy output (Eout) ÷ energy input (Ein)] x100%

To calculate Eout, you need to find which energy transferred to the box is useful. In this case, it is the gravitional potential energy, which can be found by the formula Eg = mgh, where Eg = (500.0)(9.8)(3.50) = 17150J.

To calculate Ein, find the total energy that was inputted to the object, given by W = FΔd, where W = 45000J.

Now, plug in the values to the %eff formula:

(17150J ÷ 45000J) x100% ≈ 38%

Therefore % efficiency of the pulley is 38%.

From the information provided in the question, the total mass of the nucleons is 60.49218 u.

The term nucleons refers to both the  neutrons and the protons that are found in the nucleus of atoms. We have the following information;

Mass of Proton: 1. 007825 u

Mass of Neutron: 1. 008665 u

Mass of 27 neutrons = 27(1. 008665 u) = 27.233955

Mass of 33 protons = 33(1. 007825 u) = 33.258225

Answer:

Explanation:

D) The velocity was forty meters in 10 seconds, or 4 meters per second.

The frequency of the light with the given wavelength in water is 3.75 × 10¹⁴ Hz.

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

Both frequency and wavelength are inversely proportional to each other.

Using the wavelength, frequecy and speed relation;

λ = v / f

Where λ is wavelength, v is speed and f is frequency.

Given the data in the question;

We know that frquency in water is the same as frequecy in air, it doesnt change due to medium.

From the expression above, the frequency of the light will be;

λ = v / f

f = Vw / λw

But,

Refractive index u = velocity of light in air / velocity of light in medium ( water )

So,

Vw = ( 3×10⁸m/s × 1 ) / 1.33

Vw = 2.25 × 10⁸m/s

Hence,

f = Vw / λw

f = ( 2.25 × 10⁸m/s ) / ( 6.0 × 10⁻⁷m )

f = 3.75 × 10¹⁴ s⁻¹

f = 3.75 × 10¹⁴ Hz

Therefore, the frequency of light that with the given wavelength in water is 3.75 × 10¹⁴ Hz.

A car that has a forward thrust of 3kN and accelerates from 20 m/s to 40 m/s in 10 s has a mass of 1500 kg. Thus, the mass of the car is the 1500 kg

From the question, we are to calculate the mass of the car.

From Newton's second law of motion, we have that

F = ma

Where F is the Net force

m is the mass

and a is the acceleration

Also, from one of the equations of linear motion, we have that

v = u + at

Then, we can write that

[tex]a = \frac{v-u}{t}[/tex]

Where v is the final velocity

u is the initial velocity

a is the acceleration

and t is the time taken

Therefore,

[tex]F = m\frac{(v-u)}{t}[/tex]

From the given information,

u = 20 m/s

v = 40 m/s

t = 10 s

F = 3 kN = 3000 N

Putting the parameters into the equation, we get

[tex]3000 = m \frac{(40-20)}{10}[/tex]

[tex]3000 = m \times \frac{20}{10}[/tex]

3000 = 2m

Then,

m = 3000 ÷ 2

m = 1500 kg

Hence, the mass of the car is the 1500 kg.
