Crater density and the color of the surface can be used to estimate the age of surfaces in the outer solar system.

Crater density is the number of craters per unit area on a planetary surface, and it is a useful indicator of the age of that surface. The basic principle is that the more craters a surface has, the older it is, because it has had more time to accumulate impacts.

By counting the number of craters on a surface, and comparing it to the number of craters on other surfaces of known age, scientists can estimate the age of that surface.

Another factor that can be used to estimate the age of a surface is the color of the surface. Over time, the surfaces of planets and moons are bombarded by solar radiation and cosmic rays, which can alter the chemical composition of the surface.

This alteration can change the color of the surface, and the amount of alteration can be used to estimate the age of the surface. Generally, the darker and redder the surface, the older it is, because it has had more time to be altered by radiation.

By combining these two methods, scientists can estimate the age of surfaces in the outer solar system, where direct observations and measurements are difficult to obtain. This information can help us better understand the history of these distant worlds and how they have evolved over time.

The greatest exposure to human-made ionizing radiation for most individuals is through medical X-rays.

Therefore the answer is b. Medical x-rays.

Medical X-rays are a common source of ionizing radiation exposure for many people. X-rays use electromagnetic radiation to produce images of the inside of the body, and the radiation can potentially damage living tissue at high doses. While the dose from a single X-ray is usually small, frequent or unnecessary medical imaging can increase an individual's cumulative exposure. Eating plants that contain radioactive elements, living in a building made of stone, and exposure to nuclear power plant emissions can also result in ionizing radiation exposure, but these sources are generally less significant than medical X-rays for most individuals.

Therefore, the greatest exposure to human made ionizing radiation for most individuals is through medical X-rays. Hence the correct answer is option b.

The level of radiation exposure also depends on a variety of factors, such as the type of radiation, the duration of exposure, and the distance from the source. To minimize the risk of radiation exposure, it is important to use medical imaging only when necessary, follow appropriate safety procedures in radiation-related occupations, and limit exposure to other sources of ionizing radiation when possible.

The number of revolutions the spinning disc makes during the given time is 34 revolutions .

To find the number of revolutions the spinning disc makes during the given time, we need to first find the average angular velocity and then multiply it by the time.
Step 1: Calculate the initial angular velocity (ω₁).
Given that the spinning disc rotates at 130 revolutions per minute (rev/min), we first convert it to revolutions per second (rev/s) by dividing by 60:
ω₁ = 130 rev/min / 60 = 2.167 rev/s
Step 2: Calculate the final angular velocity (ω₂).
Since the disc stops, its final angular velocity is 0 rev/s.
Step 3: Calculate the average angular velocity (ω_avg).
The average angular velocity is the mean of the initial and final angular velocities:
ω_avg = (ω₁ + ω₂) / 2 = (2.167 + 0) / 2 = 1.0835 rev/s
Step 4: Multiply the average angular velocity by time to find the number of revolutions.
The given time is 31 seconds:

The intensity at a point on the screen 2.00 mm from the center of the central maximum is approximately 0.034 W/m². The intensity at a point on the screen 1.50 mm from the center of the central maximum is approximately 0.024 W/m².

I = Imax cos² (πd sin θ / λ),

where Imax is the intensity at the center of the interference pattern, d is the distance between the two slits, θ is the angle between the line connecting the point on the screen to the center of the interference pattern and the line perpendicular to the screen, and λ is the wavelength of the light.

To find the angle θ, we can use the small angle approximation:

sin θ ≈ θ ≈ y/L,

where y is the distance from the center of the interference pattern to the point on the screen, and L is the distance between the slits and the screen.

We are given d = 0.0720 mm, λ = unknown, L = 0.800 m, Imax = 0.0700 W/m², and the distance from the center of the central maximum to the first minimum y = 3.00 mm.

Using the given distance y, we can find the value of sin θ:

y/L = sin θ,

3.00 mm / 0.800 m = sin θ,

sin θ = 0.00375.

Now we can solve for the wavelength λ:

Imax cos² (πd sin θ / λ) = I,

0.0700 W/m² cos² (π(0.0720 × 10⁻³ m)(0.00375) / λ) = I,

cos² (π(0.0720 × 10⁻³ m)(0.00375) / λ) = I / 0.0700 W/m²,

π(0.0720 × 10⁻³ m)(0.00375) / λ = ± cos⁻¹ (√(I / 0.0700 W/m²)),

λ = π(0.0720 × 10⁻³ m)(0.00375) / cos⁻¹√(I / 0.0700 W/m²)),

λ = 5.70 × 10⁻⁷ m (for the positive root).

Now we can find the intensities at the given distances from the center of the central maximum.

For y = 2.00 mm:

sin θ = y/L = 2.00 mm / 0.800 m = 0.00250,

I = Imax cos² (πd sin θ / λ)

I = 0.0700 W/m² cos² (π(0.0720 × 10⁻³m)(0.00250) / (5.70 × 10⁻⁷ m))² ≈ 0.034 W/m².

So the intensity at a point on the screen 2.00 mm from the center of the central maximum would be approximately 0.034 W/m².

For y = 1.50 mm:

sin θ = y/L = 1.50 mm / 0.800 m = 0.001875,

I = Imax cos² (πd sin θ / λ)

I= 0.0700 W/m² cos² (π(0.0720 × 10⁻³m)(0.001875) / (5.70 × 10⁻⁷ m))² ≈ 0.034 W/m².

I ≈ 0.024 W/m².

According to Ohm's law, the current induced in the frame is given by I = E/R. Thus, the current induced in the frame is: I = (-0.5Bo * L * w/To)/R = -0.5Bo * L * w/(R * To)

To determine the current induced in the frame, we need to use Faraday's law of electromagnetic induction. This law states that the magnitude of the induced electromotive force (EMF) in a closed loop is proportional to the rate of change of the magnetic flux through the loop. In other words, EMF = -dΦ/dt, where Φ is the magnetic flux through the loop.

In this case, the frame is a rectangular loop, so we can calculate the magnetic flux through it by multiplying the magnetic field by the area of the loop. Since the magnetic field varies at a constant rate from 4Bo to 6Bo in a time 8To, we can use the average magnetic field, (4Bo + 6Bo)/2 = 5Bo, to simplify our calculation. The area of the loop is Lw, where L is the length and w is the width.

Thus, the magnetic flux through the loop is given by Φ = Bavg * L * w = 5Bo * L * w.

Next, we need to calculate the rate of change of the magnetic flux, dΦ/dt. Since the magnetic field varies at a constant rate, we can use the formula for average rate of change, ΔΦ/Δt = (Φ2 - Φ1)/(t2 - t1), where Φ2 is the final magnetic flux (when the field is 6Bo), Φ1 is the initial magnetic flux (when the field is 4Bo), t2 is the final time (8To), and t1 is the initial time (0).

Plugging in the values, we get:

ΔΦ/Δt = (6Bo * L * w - 4Bo * L * w)/(8To - 0) = 0.5Bo * L * w/To

Finally, we can use Faraday's law to find the induced EMF, E = -dΦ/dt. However, we still need to account for the resistance of the frame. According to Ohm's law, the current induced in the frame is given by I = E/R.

Thus, the current induced in the frame is:

I = (-0.5Bo * L * w/To)/R = -0.5Bo * L * w/(R * To)

Note that the negative sign indicates that the induced current flows in the opposite direction to the changing magnetic field.

Bogus. In an air conditioner circuit, the voltage and current are out of stage with one another because of the presence of receptive components like capacitors or inductors. How much time shift between the voltage and current waveforms relies upon the recurrence of the air conditioner signal and the upsides of the circuit components. While the voltage waveform might lead or slack the ongoing waveform, the time contrast between their greatest qualities isn't really 1/4 of a period. It relies upon the particular circuit and the stage point between the voltage and current waveforms. Subsequently, the explanation that the voltage arrives at its most extreme worth 1/4 of a period after the ongoing arrives at its greatest worth isn't by and large obvious.
