The percentage of the iceberg that is visible above the water's surface will be 11.5% if specific gravity of ice is 0.917.

We know very well that density is defined as the division of mass with per unit volume. It is an important factor in order to find  the fluid and its properties. Its SI.unit is kg/m³.

We know very well that the mass and density relation is given by the formula

mass = density × volume

We are given density of ice = 917 kg/m³,density of the seawater=1025 kg/m³

Therefore, the ratio by which the iceberg submerge is found as

=>[tex]V_s[/tex]/V=ρ/ρ[tex]_o[/tex]

where V and ρ is defined as the volume of the iceberg and ρ is defined as the density of the substance.

=>[tex]V_s[/tex]/V=0.917/1.025

=>[tex]V_s[/tex]/V =917/1025

=>[tex]V_s[/tex]/V=0.895

or we can 89.5% of ice is submerged inside the water.

But we need to find the percentage which is visible to us, it means we need to subtract the submerged percentage from total percentage possible.

The steps that lead to a type I supernova event, in order of when they occur from first to last, are:

Initial state: The supernova process begins with a white dwarf star (WD) in a binary system. The WD is orbited by a companion star that is transferring matter onto the WD, forming an accretion disk around the WD.

Accretion disk on growing WD: As the companion star continues to transfer matter onto the WD, the accretion disk grows larger. This causes the WD to become more massive and increase in size.

WD at Chandrasekhar limit: At a certain point, the WD reaches the Chandrasekhar limit, which is the maximum mass a WD can have without collapsing. This occurs when the WD's mass is about 1.4 times the mass of the Sun.

Carbon fusion begins: As the WD continues to grow in mass and size, the pressure and temperature at its core become so high that carbon fusion begins. This process releases a huge amount of energy, which causes the WD to expand rapidly and become unstable.

Detonation: The unstable WD eventually reaches a critical point, known as the detonation point, where a sudden, explosive release of energy occurs. This is the beginning of the actual supernova event.

Final state: After the detonation, the WD continues to expand and cool, eventually becoming a supernova remnant. This is the final state of the supernova process.

The spring is then stretched by moving the bulk after which it is set free. It then moves in straightforward harmonic motion. While not maximal, it is not zero either.

The square root of the mass and the spring constant have opposite relationships with respect to the period of a spring-mass system.

If there is no friction and the mass is moved just a "small" distance from its equilibrium position at x = 0, the motion of a mass linked to a spring is said to be simple harmonic motion. The displacement needs to be minimal enough to avoid stretching the spring above its elastic limit and causing distortion.

The diver was working at a depth of 100 m. This can be determined by solving the following equation:

1.000 atm × 10.00 m = X atm × 100 m

X = 10 atm

This means that the pressure increased by 10 atm for every 100 m of depth, which means the diver was working at a depth of 100 m.

Since the temperature remained constant, the pressure increase was solely due to the change in depth.

The pressure increases by 1.000 atm for every 10.00 m of depth. This is known as the hydrostatic pressure equation, which states that pressure (P) is equal to the density of the fluid (rho) multiplied by the acceleration of gravity (g) multiplied by the depth (h):

P = rho * g * h

In this case, we can rearrange the equation to solve for h, the depth at which the diver was working:

h = P / (rho * g)

Since we know that the pressure increases by 1.000 atm for every 10.00 m of depth, we can assume that the pressure at the depth at which the diver was working is P. Therefore, we can substitute P for the pressure in the equation:

h = P / (rho * g)

Since the temperature remains constant, we can assume that the density of the fluid (rho) is also constant. Therefore, we can substitute the value of rho into the equation:

h = P / (rho * g)

Finally, we can substitute the value of acceleration of gravity (g) into the equation:

h = P

T = 9,800 N

Force = mass × accelerate

Force = 1400 kg × 0.70 m/s2

Force = 980 N

Consequently, to propel the vehicle vertically upwards towards a speed of 0.70 m/s2, the wire should endure a tension of 980 N.

A force which draws on something and extends it is known as tension in thermodynamics. This force can be applied across a thread, wire, cord, or even other media.

The de Broglie wavelength is 6.96 x 10^-33 m of a 1.90 kg rock thrown with a speed of 4.80 m/s into a pond.

λ = h/mv

λ = (6.626 x 10^-34)/(1.90 x 10^-3 x 4.80)

λ = 6.96 x 10^-33 m

Therefore, the de Broglie wavelength is 6.96 x 10^-33 m

De Broglie wavelength is a measure of the wave properties of a particle and is related to the particle's momentum. The equation for calculating the De Broglie wavelength is given by:

λ = h/p

where

λ = De Broglie wavelength

h = Planck's constant (6.626 x 10^-34 J*s)

p = momentum

The momentum of a particle can be calculated using the equation:

p = mv

where

m = mass of the particle

v = velocity of the particle

In this case, the mass of the rock is 1.90 kg and its velocity is 4.80 m/s.

Therefore, the momentum of the rock is:

p = 1.90 kg x 4.80 m/s = 9.24 kg m/s

Now we can calculate the De Broglie wavelength of the rock using the equation:

λ = h/p

λ = (6.626 x 10^-34 J*s) / (9.24 kg m/s)

λ = 7.

The de Broglie wavelength, named after the French physicist Louis de Broglie, is the quantum mechanical property of a particle that describes its wavelike behavior. It is the wavelength of a particle associated with its momentum, and is given by the equation

λ = h/p

where λ is the wavelength, h is Planck’s constant, and p is the momentum of the particle. This equation is important in understanding the behavior of particles in both classical and quantum mechanics. In classical mechanics, particles are described as having a definite position and momentum, and the de Broglie wavelength allows us to calculate the probability of a particle being in a certain position at a given time. In quantum mechanics, the de Broglie wavelength is used to calculate the probability of a particle being in a certain state.

Focal length, the amount of light that enters a substance is refracted or bent depends on the substance's refractive index. When a beam travels across the boundary between two media with refractive indices of n1 and n2, its angles of incidence and refraction are, respectively, n1 sin 1 and n2 sin 2, which describe this. The refractive indices determine the critical angle for total internal reflection, the intensity of the reflected light (Fresnel's equations), Brewster's angle, and the volume of light reflected when it reaches the interface. Since the speed of light in a medium is equal to v = c/n and the wavelength in that medium is equal to 0/n, where 0 is the wavelength of that light in vacuum, the refractive index can be thought of as the parameter that lowers those values relative to their vacuum values.
