John Dalton described atoms as small spheres that could not be divided into anything smaller.

John Dalton is the scientist who described atoms as small spheres that could not be divided into anything smaller. He proposed his atomic theory in 1803, which included the postulate that all matter is composed of tiny, indivisible particles called atoms. D

Dalton's theory also stated that atoms of different elements are unique in their mass and chemical properties and combine in simple whole-number ratios to form compounds. Dalton's model of the atom was a solid, indivisible sphere that was the smallest possible unit of an element.

While this model has been refined and updated with new discoveries, Dalton's contributions laid the foundation for the modern understanding of atomic structure and chemical reactions.

The definition of gravitational potential energy would gravitate allows to find the answers for the energy of each object on the highest rung of the ladder are:

 a) expression for gravitational potential energy is  [tex]U_p = m g \ \Delta y[/tex]

 b) Energy value

        * Body 1    U_p = 82 J

        * Body 2   U_p = 38.6 J

        * Body  3  18.5 J

The gravitational potential energy is a configuration energy that represents the amount of work that the system can do for a given configuration, its expression is

           [tex]U_p = m g \ \Delta y[/tex]

Where [tex]U_p[/tex] is the gravitational potential energy, m the mass of the body and Δy the difference in height.

In this case it indicates that the minimum height is at the bottom and is equal to zero, the steps of a ladder have a height of approximately y = 15 cm = 0.15 m

They indicate the mass of the bodies are m₁ = 3.10 kg, the mass of the body 2 m₂ = 1.46 kg , the mass of the third object is not observed, suppose it is m₃ = 0.7 kg.

They indicate that the body is placed on the last step, suppose it is a standard 18-step ladder, therefore the total height is

          y = # _ steps    y_each step

          y = 18   0.15

          y = 2.70 m

the gravitational potential energy to the capacity of the body is

body 1

              [tex]U_p[/tex] = m₁ g Δy₁

              U_p = 3.10  9.8 (2.70 -0)

               U_p = 82 J

body 2

              U_p = 1.46 9.8 ( 2.7-0)

              U_p = 38.6 J

body  3

             U_pUp = 0.70 9.8 (2.7-0)

             U_p = 18.5 J

In conclusion, using the definition of gravitational potential energy, we can find the answers for the energy of each object on the highest rung of the ladder are;

     a) expression for gravitational potential energy is  [tex]U_p = m g \ \Delta y[/tex]

     b) Energy value

        * Body 1    U_p = 82.0 J

The ball is traveling at a steady speed until it hits an unbalanced force and changes direction.

Explanation:

The ball is traveling at a steady speed until it hits an unbalanced force and changes direction. The correct option is D.

Thus, An unbalanced external force acts upon an item, Newton's first law of motion, often known as the law of inertia, asserts that an object at rest will remain at rest and an object in motion will continue to move in the same direction and at the same pace.

When a baseball is struck with a bat, it is originally at rest or moving steadily forward.

The ball experiences an imbalanced force when it is struck by the bat, altering its direction and speed. The bat's application of external force is what causes this shift in motion.

Thus, The ball is traveling at a steady speed until it hits an unbalanced force and changes direction. The correct option is D.

Answer:

Distance= 300 km

Displacement= 130

Explanation:

When you find distance you have to add

When you find displacemnet you subtract

If a car drives 215 kilometers west and then 85 kilometers south, then the distance and displacement of the car would be 300 kilometers and kilometers respectively.

Displacement is a vector quantity. This indicates that it has both a direction and a magnitude and that it is visually represented as an arrow that points from the starting position to the ending position.

As given in the problem, if a car drives 215 kilometers west and then 85 kilometers south, then we have to find the distance and displacement of the car,

The distance traveled by car = 215 kilometers + 85 kilometers

                                                = 300 kilometers

The displacement covered by the car = √(215² + 85²)

                                                               = 231.2 Kilometers

Thus, the distance traveled by car would be 300 Kilometers and the displacement would be 231.2 Kilometers in the southwest direction.

The slope of the graph, A, and the starting position of the ball, B, can be used to determine the position of the ball

Reason:

Question; The possible function representing the given equation is presented as follows;

x = A·t + B

Where;

A = 2.59 × 10⁴ [tex]\frac{cm}{s}[/tex]

B = 0.104 cm

t = Time in seconds (s)

x = The position (cm)

Required: The value of the position when t = 0.00231 s

Solution:

The position time graph of an object moving with a constant speed is a straight line with an equation of the form y = m·x + c

Plugging in the value of t = 0.00231 in the given equation gives;

x = 2.59 × 10⁴ × 0.00231 + 0.104 = 59.933

The position x of the ball at time, t = 0.00231 s is 59.933 cm

When one force is greater than another force, we can say that there is a change in motion. The correct answer is option C: "There is a change in motion."

According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. When one force is greater than another force, the net force acting on the object is not zero. If the net force acting on an object is not zero, it will cause the object to accelerate in the direction of the larger force. This acceleration leads to a change in motion. The object may speed up, slow down, change direction, or a combination of these.

Option A, "There is no net force," is incorrect because if one force is greater than another, there is a net force acting on the object.

Option B, "There is no change in motion," is incorrect because, as explained above, a greater force leads to a change in motion.

Option D, "The forces are in equilibrium," is incorrect because if one force is greater than another, the forces are not balanced, and the object is not in equilibrium.

Therefore, the correct statement is that there is a change in motion when one force is greater than another force.

If the mass of the truck is doubled, the force of friction is doubled, and the skidding distance is doubled.

Hence, the correct option is C.

The skidding distance is proportional to the mass of the truck. If the truck is heavily loaded so it has twice the total mass, the skidding distance will be twice as far.

This is because the force of friction is proportional to the normal force, which is in turn proportional to the mass of the truck. The greater the mass of the truck, the greater the force of friction, and the longer the skidding distance.

In equation form, the skidding distance is given by:

s = μ * d / f

where:

s is the skidding distance

μ is the coefficient of friction

d is the distance traveled before the truck stops

f is the force of friction

The force of friction is given by:

f = μ * mg

where:

m is the mass of the truck

g is the acceleration due to gravity

Therefore, If the mass of the truck is doubled, the force of friction is doubled, and the skidding distance is doubled.

Hence, the correct option is C.
