A particular star's spectrum shows the same hydrogen line at a wavelength of 486.0 nm. what can we conclude?

Answers

We can conclude that The star is moving toward us; shift to a shorter wavelength.

The transfer of an electron to a higher energy level, such as n = 1 or n = 2, occurs when a hydrogen atom absorbs a photon. The Balmer series refers to this group of hydrogen emission spectra.

The phrase "blueshift" describes how light waves change as an object approaches toward us in space, shifting wavelengths toward the blue end of the spectrum. Change to a shorter wavelength when the star approaches us. A shorter wavelength indicates a blueshift (shift to the blue end of the spectrum), which indicates that the object is travelling in our direction.

Therefore, We can conclude that The star is moving toward us; shift to a shorter wavelength.

Answers

a) U =  0 J

k = 0.383 J

E = 0.383 J

b) U = 0.0228 J

k = 0.155 J

E = 0.383 J

c) U = 0.1104 J

k = 0.272 J

E = 0.383 J

d) U = 0.248 J

k = 0.177 J

E = 0.383 J

Method for solving:

The equations for kinetic energy is:

k= 1/2*m*[tex]v^{2}[/tex]

The equation for elastic potential energy is:

U= 1/2*ks*[tex]x^{2}[/tex]

Where,

m= mass of the block

v= velocity

ks= spring constant

x= displacement of the spring

(a)when compression= 0 cm

U= 1/2*ks*[tex]x^{2}[/tex]

U= 1/2*552*[tex](0)^{2}[/tex]

  = 0 J

Kinetic energy:

k= 1/2*m*[tex]v^{2}[/tex]

k= 1/2*(1.05)*[tex](0.855)^{2}[/tex]

k= 0.383 J

Mechanical energy:

E= k + U

E= 0.383+0

E= 0.383 J

There will be no work done by friction or any other dissipative force, hence this energy will be conserved, or it will remain constant (like air resistance). This indicates that only spring potential energy will be created from the kinetic energy (there is no thermal energy due to friction, for example).

(b) spring potential = ?

U= 1/2* 457 N/m*[tex](0.01)^{2}[/tex]

U= 0.0228 J

Since the mechanical energy must remain constant, we may calculate the kinetic energy using the mechanical energy equation:

E= k + U

0.383= k + 0.0228

k= 0.383 - 0.228

k= 0.155

(c)spring constant when x= 0.02

U= 1/2*552*[tex](0.02)^{2}[/tex]

U= 0.1104 J

Using the equation of mechanical energy:

E= k +U

0.383= k+ 0.1104

k= 0.383 - 0.1104

k= 0.272 J

(d) U= 1/2*552*[tex](0.03)^{2}[/tex]

U= 0.2484 J

A car coasts 62. 2 meters along a hill that makes a 28. 3° angle with the ground. if the car's mass is 1234 kg, then what is the change in potential energy?

Answers

The change in Potential energy is =  662,292.459  J.

How can we calculate the value of change in potential energy?

Here, to calculate the potential energy change we use the formula,

[tex]W= F \times d \times cos\theta[/tex]

Or, [tex]W= m\times g \times d \times cos\theta[/tex]

Here we are given,

d= Distance the car makes = 62. 2 m.

[tex]\theta[/tex] = Angle that the car make along the hill =  28. 3°

F= The amount of force affect on the car = [tex]m\times g[/tex] .

m= Mass of the car = 1234 kg.

g= Acceleration of gravity = 9.8 [tex]m/s^2[/tex]

Now we substitute the known values in the above equation,

[tex]W= m\times g \times d \times cos\theta[/tex]

Or, [tex]W= 1234 \times 9.8 \times 62.2 \times cos(28.3)[/tex]

Or, [tex]W= 662,292.459 J[/tex]

From the above calculation we can conclude that the amount of work done on the car is, 662,292.459 J.

We know, from the work energy theorem that,

The change in Potential energy = The work done on the mass.

By using the equations for parabolic motion, we proceed to present the answers for the paragraph seen in the picture: a) t ≈ 0.553 s, b) s = 2.212 m, c) s = 11.060 m.

How to analyze a system on parabolic motion

A system is on parabolic motion if such system can be represented as a particle, that is, a system whose geometry is negligible, and its motion is a combination of horizontal movement at constant velocity and vertical uniformly accelerated movement due to gravity and all viscous and rotational effects are negligible.

The time required for the droplet to reach the ground is:

1.5 m = (1 / 2) · (9.807 m / s²) · t²

t = √[2 · (1.5 m) / (9.807 m / s²)]

t ≈ 0.553 s

And the horizontal distance traveled by the droplet is:

s = (4 m / s) · (0.553 s)

s = 2.212 m

Now, we apply the same procedure for the case of sneezing person:

1.5 m = (1 / 2) · (9.807 m / s²) · t²

t = √[2 · (1.5 m) / (9.807 m / s²)]

t ≈ 0.553 s

s = (20 m / s) · (0.553 s)

Answers

Liquid and gas  forms of water will be present in a 1. 0 l flask at 303 k containing a visible amount of liquid water(the vapour pressure of water at 303 k is 31. 8 mmHg).

Because the problem mentions that there is liquid water visible in the flask, liquid must be one of the correct options. Additionally, liquid water has a vapour pressure of 31.8 mmHg at the given temperature, meaning there will 31.8 mmHg of gaseous water present as well, so the correct answer is liquid and gas.

Vapour pressure or equilibrium vapour pressure is defined as the pressure exerted by a vapour in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The equilibrium vapour pressure is an indication of a liquid's evaporation rate.

It relates to the tendency of particles to escape from the liquid (or a solid). A substance with a high vapour pressure at normal temperatures is often referred to as volatile. The pressure exhibited by vapour present above a liquid surface is known as vapour pressure.

As the temperature of a liquid increases, the kinetic energy of its molecules also increases. As the kinetic energy of the molecules increases, the number of molecules transitioning into a vapour also increases, thereby increasing the vapour pressure.

The average density of the human body is given as 979 kg/ m³.

Define Law of floatation.

    Law of floatation can be defined as the volume of the liquid displaced when a body floats on the liquid surface is equal to the body submerged in the water.

As body has the stable equilibrium state, the buoyancy of the fluid will be equal to the weight.

Weight of the body floating = Weight of the body immersed in fluid

  Law of floatation = Density of the floating object / density of fluid

 As fluid is the freshwater here, the density of fluid will be 1000 kg/ m³.

                               = (979 kg/ m³) / ( 1000 kg/ m³)

                               = 97.9 %

A person is submerged when floating gently in fresh water about 97.9%.
