One type of evidence that the Earth has been through colder conditions is the presence of glacial deposits, such as till, striations, and moraines.

Glacial deposit refers to the material that has been deposited by a glacier, either through direct contact or through the action of meltwater.

This material can include rock fragments of various sizes, ranging from fine-grained clay to large boulders, as well as sand and gravel. In some cases, the material may be sorted into distinctive layers, depending on the size and type of the particles.

Glacial deposits can be found in areas that were covered by ice during the last ice age, as well as in areas that are currently covered by glaciers. They provide important clues about the movement and behavior of glaciers and can also be valuable resources for construction and other industries.

The law of reflection states that when light is reflected off a surface, the angle of incidence equals the angle of reflection.

Two plane mirrors are set at a 120-degree angle to each other in this issue. When light strikes a mirror, it is reflected. The angle of incidence equals the angle of reflection when this occurs. The angle at which a beam of light strikes a mirror is known as the angle of incidence. The angle between the reflected ray and the surface normal is known as the angle of reflection. The angle between the incident ray and the surface normal is known as the angle of incidence. When light is reflected off a surface, the angle of incidence equals the angle of reflection. When the incident ray strikes the first mirror at a 65-degree angle, the reflected ray will be reflected at a 65-degree angle. When the reflected ray hits the second mirror, it will be reflected at a 55-degree angle. To compute the final angle of reflection, we subtract this from 120 degrees. This implies that the reflected ray will leave the second mirror at a 65-degree angle. So, the answer to the question is 65 degrees.

When light is reflected off a surface, the angle of incidence equals the angle of reflection. When the first mirror is hit at a 65-degree angle of incidence, the reflected ray will be reflected at a 65-degree angle of reflection. When the reflected ray hits the second mirror, it will be reflected at a 55-degree angle. The angle of reflection can be determined by subtracting this value from 120 degrees. Thus, the reflected ray will leave the second mirror at a 65-degree angle.

In designing a device to maximize heat energy transfer, it is important to consider the materials and design elements that can facilitate efficient heat transfer.

Some key considerations include using materials with high thermal conductivity, maximizing surface area for contact between materials, and minimizing barriers to heat transfer such as insulating layers.

For example, a heat sink in a computer might use copper or aluminum, which are both materials with high thermal conductivity, to draw heat away from the CPU. The design of the fins on the heat sink can also increase the surface area available for heat transfer while reducing the thickness of any insulating layers can help to minimize barriers to heat flow.

Overall, designing for efficient heat energy transfer requires careful consideration of both materials and design elements and a deep understanding of the principles of thermal conductivity and heat transfer.

The answer is: -

The coefficient of kinetic friction between the cart and the track is 0.058 and the coefficient of static friction between the cart and the track is 0.13.

To determine the coefficient of kinetic friction, we can use the formula

\(F_{friction} = \mu_k * F_N,\)

where F_friction is the force of friction, μ_k is the coefficient of kinetic friction, and F_N is the normal force.

The normal force is equal to the force of gravity acting on the cart perpendicular to the track, which is given by

\(F_N = m * g * cos(10),\)

where m is the mass of the cart, g is the acceleration due to gravity, and 10 degrees is the angle of the track.

Plugging in the given values, we get

\(F_{friction} = \mu_k * (m * g * cos(10))\) and solving for μ_k, we get \(\mu_k = F_{friction} / (m * g * cos(10)) = 0.058.\)

To determine the coefficient of static friction, we can use the formula

\(F_{friction, max} = \mu_s * F_N,\)

where F_friction,max is the maximum force of static friction, μ_s is the coefficient of static friction, and F_N is the normal force.

Since the cart is at rest, the force of friction must be equal and opposite to the force component pulling the cart down the incline, which is \(F_{gravity} = m * g * sin(7)\), where 7 degrees is the angle of the track.

The normal force is given by F_N = m * g * cos(7). Plugging in the given values, we can solve for μ_s and get

\(\mu_s = F_{friction,max} / F_N = F_{gravity} / F_N = (m * g * sin(7)) / (m * g * cos(7)) \\\)

= tan(7) = 0.13.

Answer:

calla gringo de mierda

Explanation:

The thermal energy will be more reflected by the surface of the Marble.

The thermal energy will be more reflected by the surface of the marble because marble has a higher thermal conductivity so will absorb more heat and will release more energy.

The thermal conductivity of any material is defined as the ability of the material to transfer heat through them. If the material is more conducting more heat will transfer through it.

For example, copper has a very high thermal conductivity that's why it is used in the wiring and also used in air conditioning piping so it can transfer faster energy in a lesser time.

So the marble absorbs more heat due to its higher thermal conductivity and becomes hot and will release a higher amount of heat than the ground.

Thus the thermal energy will be more reflected by the surface of the Marble.

Explanation:

According to the question the ratio of rotational to linear kinetic energy is Krot/Klin = 0

Kinetic energy is a form of energy that an object possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. It is directly related to an object's mass and velocity. Kinetic energy can be transferred between objects and transformed into other forms of energy.

The linear kinetic energy, Klin, is given by Klin = 0.5*m*v², where m is the mass and v is the linear velocity.

Assuming that the sphere is rolling without slipping, the linear and angular velocities are related by the equation v = ω*R, where R is the radius of the sphere.

Substituting this into the equations for Krot and Klin gives:

Krot = 0.5*I*(v/R)²

Klin = 0.5*m*v²

Therefore, the ratio of rotational to linear kinetic energy is:

Krot/Klin = (I*(v/R)²)/(m*v²) = I/(m*R²)

Substituting the value for I (given as 0.4 MR2) into the equation gives:

Krot/Klin = 0

Answer:

Approximately \(1.3\times 10^{8}\; \rm m\cdot s^{-1}\).

Explanation:

Look up the speed of light in vacuum: \(c \approx 3.00\times 10^{8}\; \rm m\cdot s^{-1}\). Denote the speed as \(c\).

If the speed of light in a medium is \(v\), the refractive index of that medium would be:

\(\displaystyle n = \frac{c}{v}\).

Note, that the refractive index of a medium is inversely proportional to the speed of light in this medium. A medium with a larger refractive index would thus correspond to a slower speed of light.

Rearrange this equation to find the speed of light \(v\) in this medium:

\(\begin{aligned}v &= \frac{c}{n} \\ &= \frac{3.00\times 10^{8}\; \rm m\cdot s^{-1}}{2.4} \\ &\approx 1.25 \times 10^{8}\; \rm m\cdot s^{-1}\end{aligned}\).

The solubility of silver carbonate in water at 25°C is approximately

1.28 x 10⁻⁴ g/L

To calculate the solubility of silver carbonate (in water at 25°C, we need to use the solubility product constant (Ksp) and the balanced chemical equation for the dissociation of silver carbonate.

The balanced chemical equation for the dissociation of Ag2CO3 is

Ag₂CO₃(s) ⇌ 2Ag+(aq) + CO₃²-(aq)

Using the Ksp expression for Ag₂CO₃

Ksp = [Ag+]² [CO3²-]

substituting the equilibrium concentrations:

8.4 x 10⁻¹² = (2x)² * x

Simplifying the equation

8.4 x 10⁻¹² = 4x³

2.1 x 10⁻¹²  = x³
