Answer:

Find his gravitational then divide it by your potential

The lever's mechanical advantage would be 8.

The mechanical advantage of a lever is calculated as the ratio of the length of the effort arm to the length of the resistance arm.

In this case, the effort arm is the distance Dave pushes down on one side of the lever (2 meters), and the resistance arm is the distance the stump is lifted (0.25 meters). Therefore, the mechanical advantage of the lever is:

Mechanical Advantage = Effort Arm/Resistance Arm

Mechanical Advantage = 2/0.25

Mechanical Advantage = 8

So the lever's mechanical advantage is 8.

Explanation:

The density of the rod is 3.0 kg/m at the origin,then the center of mass of the rod is located 2.15 m from the origin.

The center of mass is the point in an object or system of objects where the mass of the object or system can be considered to be concentrated. In other words, it is the point in which an object or system can be balanced and behaves as if all the mass is concentrated at that point.

To find the center of mass of the rod, we need to integrate the product of the density and position of each infinitesimal element of the rod, divided by the total mass of the rod.

We can express the position of each element as x, where x=0 at the origin and x=4.5 m at the other end of the rod.

Let's start by finding the total mass of the rod. We can divide the rod into two parts: one from the origin to the midpoint, and the other from the midpoint to the other end. The mass of each part can be found by integrating the density over its length:

m₁ = ∫(0 to 2.25) 3x² dx = 15.19 kg

m₂ = ∫(2.25 to 4.5) (22.5x - 45.375) dx

                                = 95.63 kg

The total mass of the rod is then derived as follows:

                 m = m₁ + m₂ = 110.82 kg

We can now evaluate the location of the centre of mass. We can express the position of the center of mass as xcm, where x=0 at the origin and x=4.5 m at the other end of the rod.

We can use the formula:

xcm = (1/m) ∫(0 to 4.5) ρ(x) x dx

where (x) represents the density at position x.

We can express the density as a quadratic function of x:

                          ρ(x) = ax² + bx + c

Using the given values of density at the origin, midpoint, and other end, we can solve for the coefficients a, b, and c:

                               c = 3

                         a + b + c = 11/4.5

                           = 2.44

4a + 2b + c = 3

Solving these equations gives:

a = -1.96 kg/m³

b = 7.33 kg/m²

Now we can plug in the expression for ρ(x) and evaluate the integral:

xcm = (1/m) ∫(0 to 4.5) (-1.96x⁴ + 7.33x³ + 3x) dx

Evaluating this integral gives:

                                       xcm = 2.15 m

The work done on the ship by the tugboat is calculated as 15,000,000 joules.

Force can be a push or a pull but always with magnitude and direction.

The work done on the ship is given by the equation as : work = force × distance × cos(Ф)

force is the constant horizontal force applied by tugboat, distance is  distance moved by ship, and theta is angle between force and direction of motion of the ship. In this case, Ф is zero because the force is in same direction as the motion of ship.

Thus, we calculate the work done on the ship as: work = 5000 N × 3000 m × cos(0)

work = 15,000,000 joules

Therefore, the work done on the ship by the tugboat is 15,000,000 joules.

The final velocity of block A is -2 m/s to the left ( in the opposite direction of its initial velocity).

Quantity that designates how fast and in what direction a point is moving is known as velocity.

As we know, m_A * v_Ai + m_B * v_Bi = m_A * v_Af + m_B * v_Bf

m_A and m_B are the masses of blocks A and B, v_Ai and v_Bi are their initial velocities, and v_Af and v_Bf are their final velocities.

5 kg * 10 m/s + 10 kg * 0 m/s = 5 kg * v_Af + 10 kg * 6 m/s

50 kgm/s = 5 kg * v_Af + 60 kgm/s

-10 kg*m/s = 5 kg * v_Af

So, v_Af = -2 m/s

Therefore, the final velocity of block A is -2 m/s to the left (i.e., in the opposite direction of its initial velocity).

Angle of 5.61° should  be banked so that car running at 50 Km/hr be safe to go round the circular turn of 200 m radius.

The process of raising outer edge of the road over its inner edge through certain angle θ is called as banking of road. Banking of road is nothing but the process of making the angle between the surface of road to horizontal surface of the road. The angle made by this two surfaces is called as angle of banking. Banking of road is done for safe turn at high speed.

Angle of banking is given by the formula,

tanθ = v²÷Rg

Where θ = angle of banking

           R = Radius of circular turn

           g = acceleration due to gravity

Given,

velocity of the car v = 50km/hr = 13.88 m/s

Radius of the circular orbit = 200 m

From formula,

tanθ = 13.88² ÷ (200×9.8)

tanθ = 0.09829

θ = tan⁻¹(0.09829)

θ = 5.61°

Hence angle must be backed at 5.61° to have safe turn.

All of the following describe the region in which an electron is most likely to be found except an isotope. Thus, the correct option is B.

Isotopes can be defined as the distinct nuclear species of the same element. They have the same atomic number and the position in the periodic table as the main atom, however they differ in number of nucleons due to different numbers of neutrons in their nucleus.

Orbital is a volume of space present within an atom where an electron is most likely to be found. The s-orbitals are spherical in shape.

The rotation per second of the spin of the tube is 1200 rps. The diameter of the tube is 35 cm or 0.35 m. Then, its velocity is 1308 m/s.

Angular velocity is a physical quantity that is the rotational analogue of the linear velocity. The angular velocity of an object is the velocity of rotation that is distance covered by one rotation per second.

Given  number of rotations  = 1200 rotation per second

circumference of the tube  = 2 π r = πd

c = 3.14 × 0.35 m = 1.09 m.

It means that, for one rotation, the tube covers a distance of 1.09 m. In one second it spins 1200 times.

Hence, the total distance travelled in one second = 1200/s × 1.09 m = 1308 m/s.

Explanation:

The movement of plates is explained by the theory of plate tectonics, which proposes that the Earth's lithosphere (made up of rigid plates) moves slowly over the underlying, more fluid asthenosphere due to the circulation of heat from the Earth's interior

What is Tectonics Plates?

Tectonic plates are large pieces of the Earth's lithosphere (made up of the crust and uppermost part of the mantle) that move around on the underlying asthenosphere, a more fluid layer of the mantle. The lithospheric plates are rigid and brittle, and they move in response to forces generated by the circulation of heat in the Earth's interior. The movement of the plates causes many geological features such as mountains, volcanoes, earthquakes, and oceanic trenches.

There are several major and minor tectonic plates, including the Pacific Plate, the North American Plate, the African Plate, the Eurasian Plate, and the Antarctic Plate. These plates interact with each other at their boundaries, which can be divergent (moving apart), convergent (moving towards each other), or transform (sliding past each other).

The lithospheric plates move apart at divergent boundaries, collide at convergent boundaries, and slide past each other at transform boundaries. These interactions at the boundaries cause many geological features such as volcanoes, mountain ranges, and earthquakes. The plate tectonics theory has been supported by various lines of evidence, including the study of earthquakes, magnetic anomalies, and the distribution of fossils and rocks around the world.

The comet will disintegrate at a height of 70,479,900 m.

To find the height at which the comet would disintegrate, we need to determine Earth's Roche limit with respect to the comet.

Roche limit = 2.5 [(density of planet)/(density of moon or other object)]^(1/3) (radius of planet)

Let's assume that the moon has a similar density to the comet, so we can use the Roche limit formula with the following values:

density of planet = 5500 kg/m^3

density of moon or other object = 500 kg/m^3

radius of planet = 6378 km = 6,378,000 m

Roche limit = 2.5 [(5500 kg/m^3)/(500 kg/m^3)]^(1/3) (6,378,000 m)

Roche limit = 76,857,900 m

This means that any object that comes closer to Earth than 76,857,900 m would be torn apart by tidal forces.

Therefore, the comet would disintegrate at a height of 76,857,900 m - 6,378,000 m = 70,479,900 m above Earth's surface.
