882J of gravitational potential energy is gained by the eagle.

Here, we have been provided with data-

mass, m = 4.5 kg

height, h = 25 m

We have to find the gravitational potential energy.

In the question, it is given that the eagle is at a height of 5m and it flies from there 20 m more to reach its nest.

So, gravitational potential energy is given as

P.E = m x g x h

P.E = 4.5 × 9.8 × 20

P.E =  882J

Thus, the correct option is (b).

The most popular hardness test method is the Rockwell hardness test method, which is outlined in ASTM E-18. Before taking a Rockwell test, you should obtain a copy of this standard, read it thoroughly, and fully comprehend it. The presence of dissolved calcium and magnesium salts causes the water to be hard. The indicator known as eriochrome black T and the calcium and magnesium ions can combine to form a complex. The Brinell test, the Vicker's Diamond test, and the Rockwell test are the three that are most frequently used.

The following statements is true regarding dermatomes is O Dermatomes overlap at their edges by as much as 50%

Dermatomes are sensory areas of the skin that are innervated by a specific spinal nerve. While each dermatome provides sensory input from a specific area of the skin to a specific spinal nerve, the edges of the dermatomes may overlap by as much as 50%. This means that a given area of skin may be innervated by more than one spinal nerve. Dermatomes are used to assess spinal nerve damage and can be used to assess the level of damage to the nerve. This is important in order to provide sensory input from a broad area of the skin to a specific spinal nerve. Dermatomes are not used to assess spinal nerve damage, but rather to provide sensory information from the skin to the spinal nerve.

Work done by a force is given as the product of force and the distance moved by the force.

Work done is the product of force and the distance moved by the the force.

Thus, distance required by the 100 N force is given as:

Distance = 1000/100 = 10 m

Distance to be moved is 10 m.

Force applied = work done/ distance

Force applied by the hoist = 500/2

Force applied by the hoist = 250 N

Distance moved in one push-up = 25 cm = 0.25 m

Work done by the athlete after one push-up = 250 × 0.25 m

Work done by the athlete = 62.5 J

Distance moved by the force = 0 m

Work done = 500 × 0 = 0 N

Therefore, for work to be done, force has to move a distance.

To answer this question, we need to use the equation for sliding friction. Sliding friction is the force that opposes the motion of a box or an object that slides across a surface.

The equation for sliding friction is:f = μNwhere:f is the force of sliding friction,μ is the coefficient of sliding friction, andN is the normal force between the box and the surface on which it is sliding.We can use this equation to find the coefficient of sliding friction when we know the force required to move the box at a constant rate.Let's use the values in the question to find the coefficient of sliding friction:

f = μNf = 6.0 N (the force required to drag the box at a constant rate)N = 18 N (the weight of the box)μ = f/Nμ = 6.0 N / 18 Nμ = 0.33 (rounded to two decimal places)

Therefore, the coefficient of sliding friction is 0.33. This means that the force of sliding friction is 0.33 times the normal force between the box and the surface. This also means that it takes more force to move the box than it does to keep it moving at a constant rate.

If an object orbits the Sun at an average distance of 32 astronomical units (AU), the question is asking for the orbital period of this object in Earth years.

The orbital period of a planet or any object orbiting the Sun can be determined using Kepler's Third Law of Planetary Motion. According to Kepler's Third Law, the square of the orbital period is directly proportional to the cube of the semi-major axis of the orbit.

In this case, the average distance of the object's orbit is given as 32 AU. The semi-major axis of an elliptical orbit is equal to the average distance, so we can consider the semi-major axis as 32 AU.

Using the relationship from Kepler's Third Law, we can set up the following equation:

(T₁ / T₂)² = (a₁ / a₂)³

Letting T₁ represent the orbital period in Earth years and a₁ represent the average distance in AU, we have:

(T₁ / 1 year)² = (32 AU / 1 AU)³

Simplifying the equation, we find:

(T₁ / 1)² = 32³

T₁² = 32³

Taking the square root of both sides, we get:

T₁ = √(32³)

Calculating the value, the orbital period in Earth years would be approximately 165.77 years.

To find the magnification of an object viewed in a concave mirror, we can use the formula:

magnification = - (image distance / object distance)

Where the image distance is the distance from the mirror to the image, and the object distance is the distance from the mirror to the object. The negative sign indicates that the image is inverted.

In this case, the focal length of the concave mirror is given as f = -25.0 cm (since the mirror is concave), and the image distance is d_i = 75.0 cm. We want to find the magnification, which is given by:

magnification = - (image distance / object distance) = - (d_i / d_o)

To find the object distance, we can use the mirror equation:

1/f = 1/d_i + 1/d_o

Substituting the values we know, we get:

1/-25.0 = 1/75.0 + 1/d_o

Solving for d_o, we get:

d_o = 37.5 cm

Now we can calculate the magnification:

magnification = - (d_i / d_o) = - (75.0 cm / 37.5 cm) = -2.00

The magnification of an object viewed in a concave mirror can be calculated using the formula - (image distance / object distance). Given a concave mirror with a focal length of -25.0 cm and an image distance of 75.0 cm, the object distance is found to be 37.5 cm.

The resulting magnification is -2.00, indicating an inverted image that is twice the size of the object.

You need to create a supermesh in mesh analysis when your circuit contains a current source that is in two meshes.

A supermesh is created by combining two or more meshes in a circuit that share a common current source. This combination helps to simplify the mesh equations and makes it easier to solve for the mesh currents. A current source that is in two meshes creates a situation where the current flowing through the source depends on the current in both meshes. By combining the meshes into a supermesh, you can simplify the analysis and eliminate the current source as a variable. It's important to note that supermesh analysis should only be used when the circuit contains a current source that is in two meshes, not when the circuit contains more than two resistors, any dependent source, or any voltage source.

The angle that Boulevard N makes with Street L north of their intersection is also 75°.

Intersection is a point where two or more lines, curves, surfaces, or objects meet or cross each other. It is a common concept in mathematics, engineering, and everyday life. In mathematics, an intersection is a point where two or more sets of objects meet. In engineering, an intersection is a point where two or more roads, railways, or other transportation routes meet. In everyday life, an intersection is a point where two or more paths, streets, or other routes meet. Intersections are important in transportation, as they are the points where vehicles can change direction or turn around. Intersections are also important in mathematics, as they are the points where two or more lines, curves, or surfaces meet.

This is because the angle formed by two parallel lines is always equal. Since A and L run parallel to each other, the angle formed by Boulevard N and Street L south of their intersection is equal to the angle formed by Boulevard N and Street L north of their intersection. Therefore, the angle that Boulevard N makes with Street L north of their intersection is also 75°.
