The center of mass of the Earth-Moon system is approximately 378,366 kilometers from the center of the Earth.

To find the center of mass of the Earth-Moon system, we need to consider the Earth's mass, the Moon's mass, and the distance between their centers.

The Earth has a mass of 6.0 x 10^24 kg, and the Moon has a mass of 7.4 x 10^22 kg. The distance between the centers of the Earth and the Moon is 385,000 km.

The formula for the center of mass (CM) is:

CM = (m1 * r1 + m2 * r2) / (m1 + m2)

where m1 and m2 are the masses of the Earth and Moon, respectively, and r1 and r2 are their respective distances from the center of mass.

We can assume that r1 is the distance from the center of the Earth to the center of mass, and r2 is the distance from the center of the Moon to the center of mass. Since r1 + r2 = 385,000 km, we can rewrite r2 as (385,000 km - r1).

Now, we can substitute the given values and solve for r1:

CM = [(6.0 x 10^24 kg) * r1 + (7.4 x 10^22 kg) * (385,000 km - r1)] / [(6.0 x 10^24 kg) + (7.4 x 10^22 kg)]

After solving for r1, we get:

r1 ≈ 378,366 km

So, the center of mass of the Earth-Moon system is approximately 378,366 kilometers from the center of the Earth.

When the car is stopped by the bumpers, the maximum deflection in each spring can be determined by analyzing the forces acting on the car. Since the car is freely coasting, its kinetic energy is converted into potential energy stored in the springs.

First, we calculate the initial kinetic energy of the car:

Kinetic Energy = (1/2) * mass * velocity^2

= 112,500 lb-ft

Potential Energy = (1/2) * kA * deflectionA^2 + (1/2) * kB * deflectionB^2

To determine the maximum deflection in each spring, we need to find the point where the potential energy is maximized while satisfying the condition that the car is completely stopped. By taking the derivative of the potential energy equation with respect to each deflection and setting them equal to zero, we can solve for the maximum deflections. However, since the equations involve second-order terms, a detailed calculation is required to find the precise values.

The soil loss in  \(Mg ha^{-1}\) (Ton/ha) if the bulk density of the soil is 1.01  \(Mg m^{-3}\)  is option a. 0.202 Mg/ha.

For expressing the soil loss in \(Mg ha^{-1}\), need to convert the units appropriately. First, convert the soil loss from millimetres (mm) to meters (m) by dividing it by 1,000 (1 mm = 0.001 m). Thus, the soil loss is 0.0002 m.

Next, calculate the volume of soil lost per unit area (ha). The volume can be obtained by multiplying the soil loss (0.0002 m) by the area (ha). Since the bulk density of the soil is given as 1.01 \(Mg m^{-3}\), can convert the volume to mass by multiplying it by the bulk density.

Using the formula:

Soil loss (Mg ha-1) = Soil loss (m) × Bulk density (\(Mg m^{-3}\)) × Area (ha)

Substituting the values:

Soil loss (\(Mg ha-1\)) = 0.0002 m × 1.01 \(Mg m^{-3}\) × 1 ha

Calculating the result:

Soil loss (\(Mg ha-1\)) = 0.0002 × 1.01 = 0.000202 \(Mg ha-1\)

Therefore, the correct answer is option a. 0.202 Mg/ha.

Matter, Force

Explanation:

In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define) whereas weight is the force exerted on an object by gravity. Objects on the surface of the Earth have weight, although sometimes the weight is difficult to measure.

The Ebbinghaus learning curve refers to how quickly someone picks up new information. The spike is largest after the first attempt, then it progressively levels out, indicating that with each repetition, fewer and fewer pieces of new information are stored.

Ebbinghaus tested himself repeatedly after different amounts of time and recorded the findings in order to study the memorization of nonsensical syllables like "WID" and "ZOF" (CVCs, or Consonant-Vowel-Consonant).

German psychologist and philosopher Hermann Ebbinghaus was a pioneer in the field of memory research. Experimental psychology had only ever looked at the nature of feeling and perception up until Ebbinghaus' publication of his book (1885/1964).

The equilibrium position of the spheres depends on their conductivity; if both spheres are conductive, they will come to rest in contact, if one sphere is conductive and the other is insulating, they will come to rest separated by some distance.

Perfectly conductive spheres: Since both spheres are conductive, they will both be at the same electrical potential. Therefore, there will be no electrostatic force between them and they will come to rest in contact with each other.

One perfectly conductive sphere and one perfectly insulating sphere: The conductive sphere will distribute its charge evenly over its surface, whereas the insulating sphere will retain its charge on its surface.

This will create an electrostatic force between the two spheres, which will cause them to repel each other and come to rest separated by some distance.

Both perfectly insulating spheres: Both spheres will retain their charge on their surfaces, creating an electrostatic force between them.

The sphere with the greater charge will exert a stronger force on the other sphere and they will come to rest separated by some distance, with the sphere of greater charge closer to the common attachment point.

In conclusion, the equilibrium position of the spheres depends on their conductivity. If both spheres are conductive, they will come to rest in contact.

If one sphere is conductive and the other is insulating, it will come to rest separated by some distance due to the repulsion force. If both spheres are insulating, the sphere with greater charge will exert a stronger force and come to rest closer to the common attachment point.

Due to the repulsion force and if both spheres are insulating, the sphere with greater charge will exert a stronger force and come to rest closer to the common attachment point.

The speed of light in ethyl alcohol, which has a refractive index (n) of 1.36, is slightly slower than the speed of light in a vacuum, which is approximately 299,792,458 meters per second. To calculate the speed of light in ethyl alcohol, we can use the formula: v = c/n, where v is the velocity of light in the medium, c is the velocity of light in a vacuum, and n is the refractive index of the medium.

Using this formula, we can determine that the speed of light in ethyl alcohol is approximately 220,555,007 meters per second. This means that the speed of light is reduced by about 26% when it passes through ethyl alcohol. The reason for this reduction in speed is due to the increased density of the medium, which causes the light to slow down as it passes through.

Understanding the speed of light in different mediums is important in many fields of science and technology, including optics, telecommunications, and astronomy. By knowing the refractive index of a substance, we can determine how much light will be bent or refracted as it passes through, which can help us design and optimize various devices and systems.

When doing somersaults, you'll more easily rotate when your body is (c) curled into a ball shape. This is because of the conservation of angular momentum. Angular momentum depends on two factors: the moment of inertia and the angular velocity.

By curling your body into a ball shape, you decrease the moment of inertia, which is a measure of how spread out the mass is in an object. When the moment of inertia is reduced, the angular momentum remains constant.

By decreasing the moment of inertia, you effectively concentrate the mass closer to the axis of rotation, making it easier to rotate. In contrast, when your body is straight with both arms above your head or at your sides, the moment of inertia is larger, requiring more effort to initiate and maintain the rotation. Curling into a ball shape reduces the moment of inertia, facilitating faster and easier rotation during somersaults.

Explanation:

Answer:

7 m/s East

Explanation:

The speed of the man relative to the plane is given as 7 m/s. Given that he's walking in the corridor of the plane, this is his speed relative to the plane. Since he's moving to the back of the plane, and the aircraft is headed to west, the man's direction relative to the plane is East.

(a) The distance travelled by the object is  100 m.

(b) The displacement of the object in time interval between t = 0 s and t = 10 s is 60 m.

(a) The distance travelled by the object is calculated from the total area of the curve.

total distance = area of triangle 1 + area of triangle 2 + area of rectangle.

total distance = (¹/₂ x base x height)₁ +  (¹/₂ x base x height)₂ + length x width

total distance = (¹/₂ x 6 s x 20 m/s) +  (¹/₂ (8 - 6) 20) + (10 - 0)(10 - 8)

total distance =  60 m + 20 m + 20 m

total distance = 100 m

(b) The displacement of the object in time interval between t = 0 s and t = 10 s is calculated as follows;

displacement = final position - initial position

displacement =  (¹/₂ x base x height)₁ +  (¹/₂ x base x height)₂ + length x width

displacement = (¹/₂ x 6 s x 20 m/s) +  (¹/₂ (8 - 6) (-20)) + (10 - 0)(10 - 8)

displacement = 60 m - 20 m + 20 m = 60 m

The image of your 5.0-cm-tall nose is located **28.57 cm** away from the salad bowl, and has a height of **y' = 3.57 cm**.

To find the location and height of the image, we can use the **mirror equation** and **magnification equation**. The mirror equation is given by (1/s) + (1/s') = (1/f), where s is the object distance (50 cm), s' is the image distance, and f is the focal length. Since the salad bowl is a concave mirror, its radius of curvature (40 cm) is positive, and its focal length is half the radius, which is 20 cm. Plugging in these values, we can solve for s': (1/50) + (1/s') = (1/20). Solving for s', we find that the image is 28.57 cm away from the salad bowl.

Now, we can use the magnification equation, which is m = -(s'/s) = (y'/y), where y is the object height (5 cm) and y' is the image height. Since we already found s' (28.57 cm), we can plug in the values and solve for y': - (28.57/50) = (y'/5). Solving for y', we find that the image height is 3.57 cm.
