It takes 0.58 seconds for the cargo to hit the ground and it travels 0 feet horizontally.

What is cargo?
Bulk goods transported by water, air, or land are referred to as cargo. In the language of economics, freight refers to cargo that is transported for profit at a freight rate. Originally referring to a shipload, the term "cargo" is now used to refer to all forms of freight, including that transported by rail, van, truck, or intermodal container. Because perishable inventory is always moving toward a final end-use, even when it is kept in cold storage or another similar climate-controlled facility, the term "cargo" is also used to refer to goods in the cold-chain. Freight is a term that is frequently used to refer to the flows of goods that are transported via any mode of transportation. In particular by shipping lines and logistics operators, multi-modal container units, designed even though reusable carriers to facilitate unitized handling of a goods contained, are also known as cargo.

To solve for the time it takes for the cargo to hit the ground, we need to solve for t. To do this, we'll use Equation 1 and set y = 0, since the cargo will hit the ground at y = 0.
0 - 16.1t2 + 4.5
16.1t2 = -4.5
t2 = -4.5 / 16.1
t = √(-4.5 / 16.1) ≈ 0.58 seconds

To solve for the horizontal distance the cargo travels, we'll use Equation 2, setting t = 0.58 seconds.

0.0047(x2) + 4.5
x2 = (4.5 - 4.5) / 0.0047
x2 = 0 / 0.0047
x = √(0 / 0.0047) ≈ 0 feet

Therefore, it takes 0.58 seconds for the cargo to hit the ground and it travels 0 feet horizontally.

what is sublimation, evaporation and melting?

sublimation - Sublimation is the process by which solid substance becomes gaseous (or vapor) without going through the liquid state.

evaporation - It is the process by which a liquid becomes a gas. This is common when a puddle of water evaporates or clothing is dried after washing.

melting - The melting point is the temperature at which a solid becomes a liquid. This is 32F or 0C for water under normal atmospheric conditions. It can be influenced by pressure or impurity, so it is critical to specify the conditions.

When an object undergoing simple harmonic motion is  farthest from it's equilibrium position kinetic energy is at its minimum.

A motion in which the restoring force is directly proportional to the body's displacement from its mean position is known as a simple harmonic motion, or SHM. This restoring force always moves in the direction of the mean position.

A particle moving in simple harmonic motion accelerates as a(t) = - ω² x (t). Here, ω denotes the particle's angular velocity.

A constant exchange of kinetic and potential energy occurs in simple harmonic motion. Potential energy is at its peak and kinetic energy is zero at the distance from the equilibrium point that can be travelled the farthest. At the equilibrium point, the kinetic energy is at its peak and the potential energy is zero. The oscillating body has different values of kinetic and potential energy at other points in its motion.

Hence, when an object undergoing simple harmonic motion is  farthest from it's equilibrium position kinetic energy is at its minimum.

The fraction of ice submerged when it floats in fresh water is 0.9.

Given that the density of water is 1000 kg/m³ and density of ice is 0.917 gm/cm³.

Converting gm/cm³ to kg/m³ we get, 0.917 gm/cm³ = 917 kg/m³

ρ₁ = 1000 kg/m³, ρ₂ = 917 kg/m³

The vertical pressure or load given to a horizontal beam that causes bending is known as the bending moment. A ductility is a force that can change along a bar or beam's length and causes it to bend.

Depending on the direction of the bending, there are two different types of bending moments: Positive or negative bending: The top fiber experiences compression, which prompts a tension (or tugging) response in the bottom fibre. Young's modulus for the beam's material is same in both tension and compression.

Consequently, an optical fiber's glass core has a 0.58° index of refraction.

The ratio of the speed of light in a vacuum (c) to the speed of light in a medium (c') is known as the index of refraction (n): The propagation vector in the new medium has a different angle with respect to the normal as a result of this difference in speed when light travels from one medium to another at an angle. The refractive index of glass is 1.5. This indicates that the speed of light in glass is not independent of light color and is 1.5 times slower than in a vacuum.

The thinnest, flattest, and most aesthetically pleasing lens ever created is a high index 1.74 lens. These incredibly thin lenses provide you the best in both technology and aesthetics because they are 5% thinner than 1.67 high index lenses and approximately 50% thinner than plastic.

refractive index of glass (n₁)= 1.64

refractive index of cladding,(n₂) = 1.49

To ensure that the refracted angle in the cladding is 90°, we must determine the critical angle in the core.

Using Snell's Law we have

n₁ x sin (θ₁ ) = n₂ x sin(θ₂)

θ₂ = 90°

n₁ x sin (θ₁ ) = n₂ x sin(90°)

Ɵ₁=sin⁻¹ (n₂/n₁)

Ɵ₁=sin⁻¹ (1.49/1.64)

Ɵ₁=sin⁻¹(0.908)
