The average kinetic energy of the substance's particles is its temperature.

The average kinetic energy of a substance's particles is inversely correlated with that substance's temperature, according to the kinetic-molecular hypothesis.

When a substance is heated, some of the energy received is retained by the particles, while other energy quickens the motion of the particles. The material's temperature increases as a result of this.

The average kinetic energy of a substance's particles is directly proportional to the substance's temperature. These particles must move more quickly as the temperature rises because their mass is constant.

A ray of light is refracted by an angle of 34.5 as it enters water from glass. We need to find the angle of incidence.If the angle of refraction is given, we can find the angle of incidence using Snell's law.

Snell's law states that the ratio of the sines of the angles of incidence and refraction is constant for a given pair of media. The formula is n1sinθ1 = n2sinθ2, where n1 and n2 are the refractive indices of the two media and θ1 and θ2 are the angles of incidence and refraction, respectively.

So, we can use this formula to find the angle of incidence. Given, the angle of refraction, θ2 = 34.5 degrees.The refractive indices of glass and water are 1.5 and 1.33 respectively. So, we can substitute these values in the formula and solve for the angle of incidence.n1sinθ1 = n2sinθ2⇒ sinθ1 = (n2/n1) sinθ2⇒ sinθ1 = (1.33/1.5) sin 34.5⇒ sinθ1 = 0.753⇒ θ1 = sin⁻¹(0.753)≈ 49.9 degreesTherefore, the angle of incidence is approximately 49.9 degrees.

for the man to return to the ship he must throw the balls in the opposite direction of the ship

Explanation:

For this exercise we can use the conservation of momentum. Let's form a system made up of man and baseballs.

Initial instant. Before throwing the balls

     p₀ = 0

Final moment. After throwing the balls

     \(p_{f}\) = M v + n m v '

where M is the mass of the man, m is the mass of each ball and n is the number of balls , v isthe speed man and v' is the speed ball

Since the forces are internal, the momentum of the system is conserved

     p₀ = p_{f}

      0 = M v + n m v ’

      \(v =- \frac{n \ m}{M} \ v'\)

If we analyze this expression, for the man to return to the ship he must throw the balls in the opposite direction of the ship

Newton's laws of motion describe how seatbelts and airbags work in a car during a collision.

Newton's first law of motion, also known as the law of inertia, states that an object at rest will stay at rest and an object in motion will continue to move at a constant velocity unless acted on by an external force. Because of this rule, a passenger in a vehicle will continue moving forward at the same speed as the vehicle before the collision.

Seatbelts provide an external force that works against the motion of the occupants and slows them down, decreasing the risk of injury. The seatbelt exerts a force that brings the occupant and the vehicle to a halt, keeping them from being thrown forward. This is why wearing a seatbelt while driving is so important.

Airbags, on the other hand, employ Newton's second law of motion, which says that force equals mass times acceleration. During a collision, the airbag quickly inflates, providing a cushioning effect that reduces the occupants' forward momentum. This lengthens the time required to bring the occupants' forward motion to a halt, reducing the force acting on them and avoiding injuries, especially to the head, chest, and neck.

To summarize, both seatbelts and airbags rely on Newton's principles of motion to provide protection in the event of a collision. Seatbelts work against the motion of the occupants, while airbags reduce the force acting on them, demonstrating the application of the first and second laws of motion, respectively.

1. The power radiated away by Stuart is 191 W.

2. The radiative power absorbed by Stuart's body is 461 W.

3. The final temperature of Stuart's body will be approximately 54.4 °C.

1. The power radiated away by Stuart can be calculated using the Stefan-Boltzmann law:

Power radiated = emissivity * Stefan-Boltzmann constant * (surface area) * (temperature of body)⁴

Substituting the given values, we have:

Power radiated = 0.96 * (5.67 x 10⁻⁸ W/(m² K⁴)) * (0.4 m²) * (306 K)⁴

≈ 191 W

This calculation represents the power radiated away by Stuart's body due to its own temperature.

2. The radiative power absorbed by Stuart's body can be calculated by multiplying the incident solar radiation power per unit area by the exposed surface area and the emissivity:

Power absorbed = incident solar radiation * (exposed surface area) * emissivity

Given that only Stuart's top-half is exposed to the sun, the incident solar radiation is assumed to be 1200 W/m²:

Power absorbed = 1200 W/m² * (0.5 * 0.4 m²) * 0.96 ≈ 461 W

This calculation represents the power absorbed by Stuart's body due to the incident solar radiation.

3. The final temperature of Stuart's body is reached when the rate of heat absorption equals the rate of heat loss through radiation. In other words, when the power absorbed equals the power radiated away.

Setting the absorbed power (461 W) equal to the radiated power (191 W) and solving for the temperature, we can find the equilibrium temperature.

Power absorbed = Power radiated

1200 W/m² * (0.5 * 0.4 m²) * 0.96

= 0.96 * (5.67 x 10⁻⁸ W/(m² K⁴)) * (0.4 m²) * (final temperature)⁴

Simplifying the equation and solving for the final temperature, we find:

(final temperature)⁴ ≈ (1200 W/m² * 0.2 * 0.96) / (0.96 * 5.67 x 10⁻⁸ W/(m² K⁴))

(final temperature)⁴ ≈ 336031.68

Taking the fourth root of both sides, we get:

final temperature ≈ 54.4 °C

This calculation represents the equilibrium temperature that Stuart's body will reach while sunbathing.

The specific gravity of ice is 0.917, whereas that of seawater is 1.025. Approximately 89.51% of an iceberg is above the surface of the water.

To find out what percent of an iceberg is above the surface of the water, we need to use Archimedes' principle, which states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.

This means that an iceberg will float in water because it displaces an amount of water that weighs more than the iceberg itself.

The percentage of an iceberg above the surface of the water can be found using the following equation:

Percent above water = (Volume of iceberg above water / Total volume of iceberg) x 100

To find the volume of an iceberg above the water, we can use the following equation:

Volume of iceberg above water = Volume of iceberg x (Density of ice / Density of seawater)

So,Percent above water = [(Volume of iceberg x (Density of ice / Density of seawater)) / Total volume of iceberg] x 100

Percent above water = [(1 x (0.917 / 1.025)) / 1] x 100

Percent above water = 89.51%

Therefore, approximately 89.51% of an iceberg is above the surface of the water.

The angle of incidence for the light ray passing from water into diamond is approximately 68.1 degrees.

What is Incidence Ray?

An incident ray is a term used in optics to describe a beam of light that is traveling towards a surface or boundary where it will be either absorbed, reflected, or refracted. When an incident ray encounters a boundary between two different media with different refractive indices, some or all of the ray's energy may be reflected back into the original medium, some may be absorbed, and some may be transmitted into the second medium.

To solve this problem, we can use Snell's law, which relates the angle of incidence and the angle of refraction of a light ray passing from one medium to another:

n1sin(theta1) = n2sin(theta2)

where n1 and n2 are the refractive indices of the two media, and theta1 and theta2 are the angles of incidence and refraction, respectively.

In this case, the light ray is passing from water (n1 = 1.333) into diamond (n2 = 2.417), and we are given that the ratio of the sines of the angles of incidence and refraction is r = sin(theta2)/sin(theta1) = 14.

n1sin(theta1) = n2sin(theta2)

sin(theta2) = r*sin(theta1)

n1/n2 * sin(theta1) = r*sin(theta1)

sin(theta1) = rn2/(n1 + rn2)

theta1 = arcsin(rn2/(n1 + rn2))

Plugging in the values for n1, n2, and r, we get:

theta1 = arcsin(142.417/(1.333 + 142.417))

theta1 = 68.1 degrees

Therefore, the angle of incidence for the light ray passing from water into diamond is approximately 68.1 degrees.
