The common velocity of the two bodies after the collision is 2.7 m/s.

This can be calculated using the equation of conservation of momentum:

m1v1 + m2v2 = (m1 + m2)v

where m1 is the mass of the first body (12 kg), v1 is the velocity of the first body (4.2 m/s), m2 is the mass of the second body (18 kg), v2 is the velocity of the second body (0 m/s), and v is the common velocity of the two bodies after the collision.

Substituting the given values into the equation, we get:

12(4.2) + 18(0) = (12 + 18)v

Solving for v, we get:

Answer:

2.54 m/s

Explanation:

By conservation of energy,

work done by force due to hand = mechanical energy gained by yo-yo

So Fd = mgh + 1/2m(v₂² - v₁²)

where F = force on string = 0.19 N, d = distance moved by hand = 0.12 m, m = mass of yo-yo = 0.058 kg, g = acceleration due to gravity = 9.8 m/s², h = distance moved by yo-yo = 0.30 m, v₁ = initial speed of yo-yo = 3.4 m/s and v₂ = final speed of yo-yo = unknown

So,  Fd = mgh + 1/2m(v₂² - v₁²)

Fd/m = gh + 1/2(v₂² - v₁²)

Fd/m - gh = 1/2(v₂² - v₁²)

2(Fd/m - gh) = (v₂² - v₁²)

(v₂² - v₁²) = 2(Fd/m - gh)

v₂²  = v₁² + 2(Fd/m - gh)

taking square-root of both sides, we have

v₂  = √[v₁² + 2(Fd/m - gh)]

Substituting the values of the variables into the equation, we have

v₂  = √[(3.4 m/s)² + 2(0.19 N × 0.12 m/0.058 kg - 9.8 m/s² × 0.30 m)]

v₂  = √[(3.4 m/s)² + 2(0.19 N × 0.12 m/0.058 kg - 9.8 m/s² × 0.30 m)]

v₂  = √[(3.4 m/s)² + 2(0.0228 Nm/0.058 kg - 9.8 m/s² × 0.30 m)]

v₂  = √[(3.4 m/s)² + 2(0.393 Nm/kg - 2.94 m²/s²)]

v₂  = √[(3.4 m/s)² + 2(-2.547 m²/s²)]

v₂  = √[11.56 m²/s² - 5.094 m²/s²)]

v₂  = √[6.466 m²/s²]

v₂ = 2.54 m/s

Answer: Twice as many chromosomes as their parents.

Explanation:

2. The primary reflection from the sand/mud interface will arrive first at the hydrophone. To determine which event arrives first, we need to calculate the two-way travel times (TWTT) for each event. The TWTT for the primary reflection from the sand/mud interface is:

TWTT = (2 × depth × sin (angle of incidence)) / velocity

TWTT = (2 × 509 × sin (9)) / 1478TWTT = 0.317 s

The TWTT for the double bounce off the seafloor is:TWTT = (2 × depth) / velocityTWTT = (2 × 509) / 1478TWTT = 0.689 s

Therefore, the primary reflection arrives first at the hydrophone. Here is a simple drawing of the two-event seismic trace:

3. To calculate the time it takes for energy to travel directly from the air gun to the first hydrophone, we need to determine the distance between them and divide it by the velocity of sound in seawater. Using the given values, we have:

Distance = depth + (thickness of sand/mud) + (thickness of mudstone)

Distance = 509 + 1003 + 373

Distance = 1885 m

Velocity of sound in seawater = 1478 m/s

Time = Distance / VelocityTime = 1885 / 1478Time = 1.276 s

Therefore, it takes 1.276 seconds for energy to travel directly from the air gun to the first hydrophone.

4. The maximum takeoff angle at which seismic energy can reflect from the sand/mud interface is called the critical angle. This angle can be calculated using Snell's law:

n1 × sin (angle of incidence) = n2 × sin (angle of refraction)

where n1 and n2 are the velocities of the two materials and the angle of refraction is 90 degrees (since seismic energy travels along a horizontal path once it reaches the interface).

For the sand/mud interface, the critical angle is:

n1 × sin (critical angle) = n2 × sin (90)n1 / n2 = cos (critical angle)critical angle = cos^-1 (n1 / n2)

Using the given values:

n1 = 2793 m/s (sandstone velocity)n2 = 2240 m/s (mudstone velocity)critical angle = cos^-1 (2793 / 2240)

critical angle = 35.9 degrees

Seismic energy cannot reflect from the sand/mud interface at angles greater than the critical angle. For larger angles, the energy will be transmitted into the mudstone.

5. When seismic energy is transmitted into the mudstone, it travels in all directions away from the source. However, the energy will be attenuated (reduced in amplitude) as it travels through the mudstone due to its relatively low velocity compared to the sandstone and seawater.

As a result, the mudstone acts as a barrier that blocks or reduces the energy that would otherwise be transmitted deeper into the subsurface.

The average angular acceleration of a flywheel is \(2.1 rad/s^2\) . This value is calculated using the change in angular velocity and dividing it by the change in time.

To find the average angular acceleration of the flywheel, we need to calculate the change in angular velocity and divide it by the change in time. The initial angular velocity is given as 6.01 rotations/s counterclockwise, while the final angular velocity is 2.05 rotations/s clockwise.

To find the change in angular velocity, we can subtract the final angular velocity from the initial angular velocity:

\(Change in angular velocity = Final angular velocity - Initial angular velocity\)

= 2.05 rotations/s - (-6.01 rotations/s)

= 8.06 rotations/s

Next, division in change in angular velocity by the change in time:

\(Average angular acceleration = Change in angular velocity/Change in time\)

\(= 8.06 rotations/s / 24.1 s\\= 0.334 rotations/s^2\)

Since we need to express the answer in radians per second squared, we multiply the average angular acceleration by \(2\pi\)(since there are \(2\pi\)radians in one rotation):

Average angular acceleration = \(0.334 rotations/s^2 * 2\pi rad/rotation\)

\(=2.1 rad/s^2\) (rounded to one decimal place)

The correct answer is not provided in the given options A, B, C, or D. The distance from the axis at which the magnetic field caused by the current is equal in magnitude to Earth's magnetic field is 125 meters.

To find the distance from the conductor at which the magnetic field caused by the current is equal to the Earth's magnetic field, we'll use the formula for the magnetic field around a long straight conductor:

\(B = (de * I) / (2 * \pi  * r)\)

Where B is the magnetic field, μ₀ is the permeability of free space (\(4\pi  * 10^-7 Tm/A\)), I is the current, and r is the distance from the conductor. We want to find the value of r when B equals Earth's magnetic field (0.5 x 10⁻⁴ T).

\(0.5 * 10^-4 T = (4\pi  * 10^-7 Tm/A * 100 A) / (2 * \pi  * r)\)
To solve for r, we can first simplify the equation by cancelling the π terms:

\(0.5 * 10^-4 T = (4 * 10^-7 Tm/A * 100 A) / (2 * r)\)

Now, cancel out the A (Amperes) terms:

\(0.5 * 10^-4 T = (4 * 10^-7 Tm) / (2 * r)\)

Divide both sides by 4 x 10⁻⁷ T:

\(r = (0.5 * 10^-4 T) / (4 * 10^-7 T)\)

Simplify the equation:

r = \(0.5 * 10^3 m / 4\)
r = 500 / 4
r = 125

To calculate the time it would take Eileen to save for the outright purchase of the car using the interest payments from her credit card debt, we need to consider the finance charges she pays and the interest she earns on her savings.

Given:

Finance charges paid per year = $1,080

Cost of the car = $9,000

Interest rate on savings = 4%

First, we need to determine how much Eileen can save each year by using the finance charges. This amount is equal to the finance charges paid per year, which is $1,080.

Next, we calculate the interest Eileen can earn on her savings each year. This can be calculated using the interest rate of 4% on her savings.

Now, we can calculate the number of years it would take Eileen to save enough to purchase the car outright by dividing the cost of the car by the savings she can accumulate each year.
