An observer notices that the sun is directly overhead at midday during the summer solstice. what is this observer's latitude upon the earth?

Answer:

True

Explanation:

The force responsible for the acceleration of the crate is the frictional force between the crate and the bed of the truck.

When the truck accelerates, the crate tends to remain at rest due to inertia. However, the frictional force between the crate and the bed of the truck acts in the forward direction, allowing the crate to accelerate along with the truck.

This frictional force is a result of the interaction between the surfaces of the crate and the truck bed. Without this frictional force, the crate would slide or move independently from the truck's acceleration.

The frictional force arises due to the microscopically rough surfaces of the crate and the truck bed. As the two surfaces are pressed against each other, intermolecular forces come into play, resulting in the generation of the frictional force

(a) To determine the temperature of the copper plate, we can use the formula:

Q = m_dot x Cp x (T_out - T_in)

where Q is the heat transfer rate, m_dot is the mass flow rate of water, Cp is the specific heat capacity of water, and T_out and T_in are the outlet and inlet temperatures of the water, respectively.

The heat transfer rate can be calculated as:

Q = 100 x 25 W = 2500 W

The mass flow rate of water can be calculated as:

m_dot = rho x V x A

where rho is the density of water, V is the velocity of water, and A is the area of the plate.

rho = 1000 kg/m³ (density of water)

V = 2 m/s (given)

A = 0.2 m x 0.2 m = 0.04 m² (area of the plate)

Therefore, m_dot = 1000 kg/m³x 2 m/s x 0.04 m² = 80 kg/s

The specific heat capacity of water is Cp = 4186 J/kg-K.The outlet temperature of the water is given as T_out = 17°C = 290 K (approx).

Assuming the copper plate is isothermal, we can equate the heat transfer rate to the thermal energy generated by the components:

Q = 100 x P

where P is the power dissipation per component.

Therefore, P = Q/100 = 25 W

The contact resistance between the component and the copper plate is given as 2 x 10⁴ m² K/W. The contact area between each component and the copper plate is 1 cm²= 0.0001 m².

Using the formula for the thermal resistance of a component:

R_th = 1/(h x A_c)

where h is the heat transfer coefficient and A_c is the contact area, we can calculate the value of h:

R_th = 2 x 10⁴m² K/W

A_c = 0.0001 m²

Therefore, h = 1/(R_th x A_c) = 5000 W/m² K

Assuming the components are at a uniform temperature, we can use the formula for convection heat transfer to calculate the component temperature:

P = h x A_c x (T_plate - T_comp)

where T_comp is the component temperature.

Rearranging the formula, we get:

T_comp = T_plate - (P/(h x A_c))

The temperature of the copper plate is approximately 82.3°C, which can be calculated using the first formula.

Plugging in the values, we get:

Q = 80 kg/s x 4186 J/kg-K x (290 K - T_plate)

Solving for T_plate, we get:

T_plate = 82.3°C

(b) The component temperature can be calculated using the second formula:

T_comp = T_plate - (P/(h x A_c))

Plugging in the values, we get:

T_comp = 82.3°C - (25 W/(5000 W/m² K x 0.0001 m²)) = 57.3°C

Therefore, the temperature of each component is approximately 57.3°C.

Answer:

Explanation:

When total internal reflection happens at a plastic-air interface, light hits the interface from the plastic side. The correct answer is Option D.

Total internal reflection is a phenomenon that happens when a light ray tries to pass from a medium of high refractive index to another medium with a low refractive index. When the angle of incidence becomes greater than the critical angle of the interface, the light rays are refracted and stay inside the medium of high refractive index. If the angle of incidence is even greater, the light is reflected back into the same medium as it was coming from.

In the case of total internal reflection, the incident angle is greater than the critical angle, so the light is reflected back. The total internal reflection only occurs when the light goes from a medium with a higher refractive index to a medium with a lower refractive index.

The law of reflection holds for total internal reflection. When a ray of light hits a plastic-air interface from the plastic side with an angle of incidence greater than the critical angle, then total internal reflection occurs. Therefore, the correct option is "d) light hits the interface from the plastic side."

White light, consisting of many wavelengths, is known as "polychromatic light," whereas light consisting of one wavelength is known as "monochromatic light."

White light is composed of a range of wavelengths spanning the visible spectrum. When white light passes through a prism or a diffraction grating, it gets separated into different colors, such as red, orange, yellow, green, blue, indigo, and violet. Each of these colors corresponds to a specific wavelength within the visible spectrum.

Polychromatic light refers to light that consists of multiple wavelengths. In the case of white light, it contains a combination of all the visible wavelengths, resulting in the perception of "white" when observed together.

On the other hand, monochromatic light refers to light that consists of only a single wavelength. It is a pure and specific color of light without any mixture of other wavelengths. Examples of monochromatic light sources include lasers, which emit light at a specific wavelength, such as red, green, or blue.

Answer:

Contact forces are forces that act between two objects that are physically touching each other.

Think of a cube that is 1 cm by 1 cm by 1 cm. The volume of this cube is 1*1*1 = 1 cubic cm = cm^3. This is equivalent to 1 mL by definition

So the object's volume of 5 mL is the same as 5 cm^3.

To get the density of an object, we divide the mass over volume

density = (mass)/(volume)

density = (20 kg)/(5 mL)

density = (20 kg)/(5 cm^3)

density = (20/5) (kg/cm^3)

density = 4 kg/cm^3

The density is 4 kilograms per cubic centimeter. In other words, each cubic centimeter of volume has about 4 kilograms of material.

The gravitational potential energy (GPE) of the nickel will increase as it falls to the ground due to the force of gravity acting on it.

When an object falls, it gains kinetic energy, which is the energy of motion. As an object falls, it gains kinetic energy at the expense of its potential energy.

The amount of GPE gained will be equal to the mass of the nickel multiplied by the acceleration due to gravity and the change in height from the worker's pocket to the ground. Specifically, the change in GPE = 0.005 kg \(* 9.8 m/s^2 * 169\)*  m. As the nickel falls it will accelerate and its kinetic energy will increase as well.

(a)The interference between the two waves produced by the in-phase sources is constructive (c) the locations where the same type of interference occurs are at angles of 44.6° and 79.1° with the line joining the two sources. (b )The smaller distance  is 2.96s.s .

The given problem involves two in-phase sources of waves that are separated by a distance of 3.99 m. These sources produce identical waves with a wavelength of s.s them, and we need to find out the locations where the same type of interference occurs and whether it is constructive or destructive interference.

(a) To determine whether the interference is constructive or destructive, we need to calculate the phase difference between the two waves. If the phase difference is an even multiple of π (i.e., 0, 2π, 4π, etc.), the interference is constructive. If the phase difference is an odd multiple of π (i.e., π, 3π, 5π, etc.), the interference is destructive. In this case, the phase difference between the two waves is zero since they are in-phase. Therefore, the interference is constructive.

(b) To find the locations where constructive interference occurs, we need to use the formula d sinθ = mλ, where d is the distance between the two sources, θ is the angle between the line joining the two sources and the line perpendicular to the screen, m is an integer, and λ is the wavelength of the waves. For constructive interference, m can be 0, ±1, ±2, etc. The smallest distance at which the same type of interference occurs corresponds to m = 1. Thus, we have 3.99 sinθ = 1s.s them, which gives sinθ = 1s.s them/3.99. Solving for θ, we get θ = sin⁻¹(1s.s them/3.99) ≈ 44.6°. Therefore, the location where constructive interference occurs is at an angle of 44.6° with the line joining the two sources.

(c) To find the other location where constructive interference occurs, we need to use the same formula as above but with m = 2. Thus, we have 3.99 sinθ = 2s.s them, which gives sinθ = 2s.s them/3.99. Solving for θ, we get θ = sin⁻¹(2s.s them/3.99) ≈ 79.1°. Therefore, the other location where constructive interference occurs is at an angle of 79.1° with the line joining the two sources.

In conclusion, the interference between the two waves produced by the in-phase sources is constructive, and the locations where the same type of interference occurs are at angles of 44.6° and 79.1° with the line joining the two sources. The smaller distance between these two locations is 2.96s.s them, and the units of the answer depend on the units used for the wavelength.
