The electric force of repulsion between nuclear protons is 230 Newton.The size of the force varies inversely as the square of the distance between the two charges.

Electric charge consists of two types i.e. positively electric charge and negatively electric charge.There was a famous scientist who investigated about this charges. His name is Coulomb and succeeded in formulating the force of attraction or repulsion between two charges i.e. :

F = electric force (N)

k = electric constant (N m² / C²)

q = electric charge (C)

r = distance between charges (m)

The value of k in a vacuum = 9 x 10⁹ (N m² / C²)

F = k(q1 q2)/ r^2

Distance between protons = d = 10⁻¹⁵ m

charge of proton = q = 1.6 × 10⁻¹⁹ C

Here q1=q2

electric force = F =230N

Coulomb's Law: Two protons in an atomic nucleus are typically separated by a distance of 2×10−15m. The electric repulsive force between the protons is huge, but the attractive nuclear force is even stronger and keeps the nucleus from bursting apart.

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 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

The sound waves travel through the medium; for this current situation, the air and skirt off the gorge wall and return to the beginning of the sound (you). The outcome is that you hear the reverberation of your holler.

T=1400 kg x 0.70 m/s2.

T = 9,800 N

First, figure out how much force is needed to start the car moving.

Force = mass × accelerate

Force = 1400 kg × 0.70 m/s2

Force = 980 N

Step 2: Calculate the tension in the cable.

Tension = Force

Tension = 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. Pulling apart of the medium's extremities causes it to decompress, which is the reverse of compression.

Now here given that the velocity is constant, then the work energy is zero.

So, work done by the potential energy of the object and that of the viscous liquid we have

The focal length of a camera lens, which is frequently stated in millimeters, is its fundamental description (mm), to the point where light rays converge to form a sharp image of an object.

An optical medium's refractive index, commonly referred to as the refraction index, is a dimensionless statistic that describes how well the medium bends light. 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. This assumes that vacuum has a refractive index of 1, and that the frequency of the wave (f = v/) is unaffected by the refractive index.
