Calculate the distance a trailer weighing 2800 N is towed with an acceleration of 1.6 m / s² when the work being done is known to be 15000 Joules.​

(a) If the orbital period of Eris is 559 years then the semi major axis of Eris is 67.864 AU (10.152 Tm)

(b) Aphelion distance is 97.5 AU, while its perihelion distance is 38.3 AU then it's orbit is very eccentric .

It's eccentricity would be 0.43607.

One of our solar system's biggest dwarf planets is Eris. Despite being three times further from the Sun, it is roughly the same size as Pluto.

Eris at first glance seemed bigger than Pluto. This sparked a discussion among scientists, and the International Astronomical Union ultimately decided to define the definition of a planet in 2006. The objects Pluto, Eris, and several like them are currently categorized as dwarf planets.

Eris was found on January 5, 2005, using information gathered on October 21, 2003 by Mike Brown, a professor of planetary astronomy at the California Institute of Technology, Chad Trujillo, of the Gemini Observatory, and David Rabinowitz, of Yale University, during a Palomar Observatory survey of the outer solar system.

Possibility of Life

It appears implausible that life could live on Eris' surface given how frigid it is there.

Dimension and Distance

Eris is approximately 1/5 the radius of Earth, with a radius of around 722 miles (1,163 kilometers). Like Pluto, Eris is a bit smaller than the Moon. Eris would be around the size of a popcorn kernel if the Earth were the size of a nickel.

Eris is 68 astronomical units from the Sun at an average distance of 6,289,000,000 miles (10,125,000,000 kilometers). The distance between the Sun and Earth is one astronomical unit, or AU. From here, sunlight travels from the Sun to Eris' surface over the course of more than nine hours.

Rotation and Orbit

One orbit of the Sun by Eris takes 557 years on Earth. The Kuiper Belt, a region of frozen debris beyond Neptune's orbit, lies well beyond Eris' plane of orbit, which is far outside the plane of the solar system's planets.

Eris has days that are comparable to ours in length since it rotates around the Sun every 25.9 hours.

Explanation:

sorry, it's B, not a made a mistake in the approximation

a) To determine if the car will hit the object before coming to a stop, we need to calculate the distance required to stop the car, assuming maximum braking deceleration. We can use the following formula:

d = (v^2) / (2a)

where:

d = distance required to stop

v = initial velocity

a = acceleration/deceleration

In this case, v = 100 km/h = 27.78 m/s (converted from km/h to m/s)

a = -7 m/s^2 (negative sign indicates deceleration)

We know that the car's headlights extend out to a range of 30 m, so if the distance required to stop the car is greater than 30 m, the car will hit the object before coming to a stop.

Plugging in the values to the formula, we get:

d = (27.78^2) / (2 x -7) = 108.61 m

Since 108.61 m is greater than 30 m, the car will hit the object before coming to a stop.

b) To calculate the time required to stop, we can use the following formula:

t = v / a

where:

t = time required to stop

v = initial velocity

a = acceleration/deceleration

Plugging in the values, we get:

t = 27.78 / 7 = 3.97 s

Therefore, it will take 3.97 seconds to stop the car.

To derive the equation for the buoyant force, we can start with the equation for the pressure from a fluid at a certain depth:

P = ρgh + Patm

where P is the pressure at a depth h, ρ is the density of the fluid, g is the acceleration due to gravity, and Patm is the atmospheric pressure at the surface of the fluid.

Now, let's consider a simple submerged object, such as a perfect cube with sides of length s, as the hint suggests. The object is fully submerged in the fluid, so it experiences a pressure difference between the top and bottom surfaces. The pressure at the top surface of the object is Ptop = ρghtop + Patm, where htop is the depth of the top surface below the surface of the fluid. The pressure at the bottom surface of the object is Pbottom = ρghbottom + Patm, where hbottom is the depth of the bottom surface below the surface of the fluid. Since the object is at rest in the fluid, the net force acting on the object must be zero. Therefore, the buoyant force must be equal and opposite to the weight of the object:

Buoyant force = Weight of object

The weight of the object is given by its mass multiplied by the acceleration due to gravity:

Weight of object = mg

where m is the mass of the object and g is the acceleration due to gravity.

To find the buoyant force, we need to find the difference between the pressure at the top and bottom surfaces of the object, and then multiply that difference by the surface area of the object:

Buoyant force = Pressure difference × Surface area

The pressure difference is given by:

Pressure difference = Pbottom - Ptop

= (ρghbottom + Patm) - (ρghtop + Patm)

= ρg(hbottom - htop)

Therefore, the buoyant force is:

Buoyant force = ρg(hbottom - htop) × Surface area

For a perfect cube with sides of length s, the surface area is given by A = 6s^2. Therefore, the buoyant force on the cube is:

Buoyant force = ρg(hbottom - htop) × 6s^2

This is the equation for the buoyant force on a submerged object, derived from the equation for the pressure from a fluid at a certain depth and the concept of the buoyant force being due to the pressure difference between the top and bottom of an object.

Explanation:

Segment a, which is drawn from the center of the polygon perpendicular to one of its sides, is called the apothem.

The typical hexagon has a surface area of around 874.6 square meters.

To find the area of a regular polygon, use the formula:

Area = (1/2) x Perimeter x Apothem

Find the perimeter of the polygon. Since the polygon has n sides, use the formula:

Perimeter = n x s

where s = length of one side.

Since s = 18m, find n by using the formula:

n = 360° / (180° - (360° / n))

where n = number of sides.

Plugging in the values:

n = 360° / (180° - (360° / n))

n = 360° / (180° - (360° / 6))

n = 6

So the polygon has 6 sides, which makes it a hexagon.

Now find the perimeter:

Perimeter = n x s

Perimeter = 6 x 18

Perimeter = 108m

Next, find the apothem, use the formula:

Apothem = s / (2 x tan(π/n))

Plugging in the values:

Apothem = 18 / (2 x tan(π/6))

Apothem = 9√3 m

Now use the formula for the area:

Area = (1/2) x Perimeter x Apothem

Area = (1/2) x 108 x 9√3

Area ≈ 874.6 m²

Therefore, the area of the regular hexagon is approximately 874.6 square meters.

Answer:

The height from which the diver jumped can be calculated using the laws of motion and the principle of conservation of energy.

Let's assume that the diver jumped from a platform with an initial velocity of zero. The potential energy (PE) of the diver at the top of the platform is given by:

PE = mgh

Where m is the mass of the diver, g is the acceleration due to gravity (9.8 m/s^2), and h is the height from which the diver jumped.

When the diver jumps, the potential energy is converted into kinetic energy (KE) as the diver moves downwards. The kinetic energy of the diver just before hitting the water is given by:

KE = (1/2)mv^2

Where v is the velocity of the diver just before hitting the water.

According to the principle of conservation of energy, the potential energy at the top of the platform is equal to the kinetic energy just before hitting the water. Therefore, we can equate the two equations above and solve for h:

mgh = (1/2)mv^2

h = (1/2)v^2/g

We need to find the value of v to calculate h. We can use the kinematic equation:

v^2 = u^2 + 2as

Where u is the initial velocity (which is zero in this case), a is the acceleration due to gravity (9.8 m/s^2), and s is the distance travelled by the diver (which is equal to h).

Substituting the values, we get:

v^2 = 2gh

v^2 = 2 * 9.8 * h

v^2 = 19.6h

Therefore:

h = v^2/(19.6)

Now, let's assume that the velocity of the diver just before hitting the water was 10 m/s (a reasonable value for a diving competition). Then:

h = (10^2)/(2*9.8) = 51 meters

Therefore, the height from which the diver jumped is approximately 51 meters.

Answer:

the energy of the spring at the start is 400 J.

Explanation:

Given;

mass of the box, m = 8.0 kg

final speed of the box, v = 10 m/s

Apply the principle of conservation of energy to determine the energy of the spring at the start;

Final Kinetic energy of the box = initial elastic potential energy of the spring

K.E = Ux

¹/₂mv² = Ux

¹/₂ x 8 x 10² = Ux

400 J = Ux

Therefore, the energy of the spring at the start is 400 J.

Answer:

- 0.33 m/s

Explanation:

An illustration is shown above,

In this case, since the two objects move in opposite directions before collision, then move together, the formula to be used is,

m1u1 - m2u2 = (m1 + m2)v

Where,

m1 = mass of the first object

u1 = initial velocity of the first object

v1 = final velocity of the first object

m2 = mass of the second object

u2 = initial velocity of the second object

v2 = final velocity of the second object

Therefore,

(4.0 • 3.0) - (8.0 • 2.0) = (4.0 + 8.0)v

12 - 16 = 12v

-4 = 12v

Divide both sides by 12,

-4 / 12 = 12v / 12

-1 / 3 = v

v = -0.33 m/s

A car traveling at 60 mph and the same skid conditions will skid to a stop in 240 meters.

What is the distance a car traveling at 60 mph and the same skid conditions will skid to a stop?

The distance a car skids to come to a stop is directly proportional to the square of its speed. This means that if the speed is doubled, the distance it will take to stop will be quadrupled.

Let's use this formula to find the distance the car will skid to come to a stop at 60 mph:

(d1 / d2) = (v1^2 / v2^2)

where:

d1 = distance the car skids at 30 mph = 60 meters

v1 = speed of the car at 30 mph = 30 mph

v2 = speed of the car at 60 mph = 60 mph

d2 = distance the car skids at 60 mph (what we want to find)

Plugging in the values, we get:

(d1 / d2) = (v1^2 / v2^2)

60 / d2 = (30^2 / 60^2)

60 / d2 = 1 / 4

d2 = 4 x 60

d2 = 240 meters

Answer:

The amount of time needed to stop the marble is much less than the amount of time needed to stop the basketball.

Explanation:

To explain this question we can use the equation:

Change in momentum = Force x Time

Where momentum = mass x Velocity

In the case of the basketball, it has a much larger mass than the marble, meaning it has much more momentum than the marble. This means that with the same amount of force, it will need much more time to stop.

Likewise, the marble has less mass than the basketball meaning it will have less momentum. This means that with the same amount of force, it will require less time to stop.

Logically this also makes sense if we think about it in a real life scenario. If we try to stop a marble with our finger, we can stop it much faster then if we try to stop a basketball with our finger because of the difference in mass between the two objects, therefore the marble will require much less time to be stopped than the basketball.

Hope this helped!
