What is the correct formula for wavelength as a function of energy?

Answers

Answer 1

The relationship between wavelength, energy, and frequency is expressed by the formula E = hv = hc/, where E is energy, h is Planck's constant, v is frequency, c is the speed of light, and w is wavelength.

How do you determine a function's wavelength? The relationship between wavelength, energy, and frequency is expressed by the formula E = hv = hc/, where E is energy, h is Planck's constant, v is frequency, c is the speed of light, and w is wavelength. The formula wavelength = wave velocity/frequency can be used to determine wavelength.Wavelength is typically measured in meters.Greek lambda is the sign for wavelength, therefore = v/f.Wavelength and frequency have a connection to energy just as they do to light.Higher frequency and shorter wavelengths are correlated with more energy.Therefore, lower energy is produced when the wavelengths are longer and the frequency is lower.E = h is the formula for energy.

Answers

Answer:

The water rises by 4.45 m

Explanation:

Mass is constant

Mass = Volume /Specific Volume

Mass = 200/(1*10^-3*1.001) = 199.8 Kg

Volume after heating = specific volume * mass

= 1.008 *10^-3 lt/gm * 199800 gm

= 201.398 t

Change in volume = 1.3986

(pi)r^2 *h = 1.3986 *10^-3 m^3

3.14 * (1*10^-2 m)^2 *h = 1.3986 *10^-3 m^3

H = 4.45 m

A 2.0 kg sphere with a velocity of 6.0 m/s collides head-on and elastically with a stationary 10 kg sphere

Answers

Question: A 2.0 kg sphere with a velocity of 6.0 m/s collides head-on and elastically with a stationary 10 kg sphere, What is thier velocities after collision.

Answer:

v = 6 m/s, v' = 0 m/s

Explanation:

From the question,

For Elastic collision,

mu+m'u' = mv+m'v'......................... Equation 1

Where m = mass of the first sphere, m' = mass of the second sphere, u = initial velocity of the first sphere, u' = initial velocity of the second sphere, v = final veolocity of the first sphere, v' = final velocity of the second sphere.

Also,

The relative velocity before collision = relative velocity after collision

u-u' = v-v'............................ Equation 2

Given:  m = 2 kg, m' = 10 kg, u = 6 m/s, u' = 0 m/s

Substitute into equation 1 and 2

2(6)+10(0) = 2v+10v'

2v+10v' = 12.............. Equation 3

6-0 = v-v'

v-v' = 6 ................... Equation 4

Solve equation 3 and 4 simultaneously.

v = 6+v'............. Equation 5

Substitute equation 5 into equation 3

2(6+v')+10v' = 12

12+2v'+10v' = 12

12v' = 12-12

v' = 0/12

v' = 0 m/s.

Also substitute the value of v' into equation 5

v = 6+0

v = 6 m/s

How much force does it take to accelerate a 3.50 kg mass from 3.00 m/s to 17.0 m/s in a time of 2.00 seconds?

Answers

Answer:

Force = 24.5 Newton

Explanation:

Given the following data;

Mass = 3.50 kg

Initial velocity, u = 3 m/s

Final velocity, v = 17 m/s

Time, t = 2 seconds

To find the force;

First of all, we would determine the acceleration of the object using the formula;

Acceleration = (v - u)/t

Acceleration = (17 - 3)/2

Acceleration = 14/2

Acceleration = 7 m/s²

Now, we can find the force using the formula;

Force = mass * acceleration

Force = 3.5 * 7

Force = 24.5 Newton

The acceleration due to gravity on the Moon's surface is known to be about one-sixth of the acceleration due to gravity on the Earth.
A rock falls under a gravitational force of 16.3 N on the moon.
Please help me figure out the mass of the rock.

Answers

Answer:

The mass of the rock is approximately 9.97 kg

Explanation:

From the question, we have;

The acceleration due to gravity on the Moon = (1/6) × The acceleration due to gravity on the Earth

The gravitational force under which a rock falls on the Moon = 16.3 N

The acceleration due to gravity on Earth, g ≈ 9.81 m/s²

Therefore, the acceleration due to gravity on the Moon, a = (1/6) × 9.81 m/s² ≈ 1.635 m/s²

The relationship between the force with which the rock falls and the acceleration of the motion resulting in the force is given by the following relationship;

F = m × a

Where;

F = The force = 16.3 N

m = The mass of the object acted on by the force = The mass of the rock

a = The acceleration of the motion of the object = 1.635 m/s²

From F = m × a, we have;

m = F/a

∴ m = 16.3 N/(1.635 m/s²) = 9.96941896 kg

The mass of the rock, m ≈ 9.97 kg.

Question:
Define work.

Answers

Answer:

Work, in physics, refers to the measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.

Hey there!

Work is defined as the the force which gets applied to an object in order to displace (move) it. For example, you work in order to walk up & down the stairs. For this, you need to apply force as well. So, work done = force × distance.

Calculate the refractive index for a substance where the angle of incidence is 300 , the angle of refraction is 600 , and the refractive index of second substance is 1.5

Answers

Answer:

η₁ = 2.6

Explanation:

Here, we will use snell's law to calculate the refractive of the substance:

[tex]\frac{\eta_2}{\eta_1} = \frac{Sin\theta_1}{Sin\theta_2}[/tex]

where,

η₁ = refractive index of first substance = ?

η₂ = refractive index of second substance = 1.5

θ₁ = angle of incidence = 30°

θ₂ = angle of refraction = 60°

Therefore,

[tex]\frac{1.5}{\eta_1} = \frac{Sin\ 30^0}{Sin\ 60^0}[/tex]

η₁ = 2.6

A machine raised a load of 360N through a distance of 0.2m. The effort, a force of 50N moved 1.8m during the process. Calculate the efficiency of the machine.
Select one:
a. 40%
b. 100%
c. 80%
d. 60%

Answers

Answer:

c. 80%

Explanation:

Given;

load raised by the machine, L = 360 N

distance through which the load was raised, d = 0.2 m

effort applied, E = 50 N

distance moved by the effort, e = 1.8 m

The efficiency of the machine is calculated as follows;

[tex]Efficiency = \frac{ 0utput \ work }{1nput \ work} \times 100\% \\\\Efficiency = \frac{Load \ \times \ distance \ moved \ by \ load }{Efort \ \times \ distance \ moved \ by \ effort} \times 100\%\\\\Efficiency = \frac{360 \times 0.2}{50 \times 1.8} \times 100\%\\\\Efficiency =80\%[/tex]

Therefore, the efficiency of the machine is 80%

Answers

Answer:

A) ( - 200t + 40 ) volts

B)  b) anticlockwise ,  c) anticlockwise , d) clockwise ,  e) clockwise

Explanation:

Given data:

magnetic flux (Φm) = 5.0t^2 − 2.0t

number of turns = 20

a) determine induced emf

E = - N [tex]\frac{d\beta }{dt}[/tex]

  =  - N ( 10t - 2 ) = - 20 ( 10t - 2 )

  =  - 200t + 40  volts

b) Determine direction of induced current

i) at t = 0

 E = - 0 + 40  ( anticlockwise direction )

ii) at t = 0.10

E = -20 + 40 =  20 ( anticlockwise direction )

iii) at t = 1

E = - 200 + 40 = - 160 ( clockwise direction)

iv) at t = 2

E = -400 + 40 =  - 360 ( clockwise direction )
