CUAL DE LAS SIGUIENTES LEYES NO PERTENECEN A LOS 3 PRINCIPIOS DE NEWTON? 1.LEY DE LA ATRACCION 2.LEY FUNDAMENTAL DE LA DINAMICA 3.LEY DE ACCION Y REACCION 4.LEY DE LA INERCIA

Answers

Answer 1

Answer:

La Ley de atracción no pertenece a los tres principios de Newton.

Explanation:

Las leyes de Newton son tres principios que sirven para describir el movimiento de los cuerpos, basados en un sistema de referencias inerciales (es aquél que está en reposo o se mueve con velocidad constante, es decir, no tiene aceleración).

Las 3 leyes de Newton son:

Primera Ley o Ley de Inercia : Esta ley enuncia que todo cuerpo permanece en su estado de reposo o de movimiento rectilíneo uniforme a menos que otros cuerpos actúen sobre él. Explica que para modificar el estado de movimiento de un cuerpo es necesario actuar sobre él. Segunda ley o Principio Fundamental de la Dinámica : Esta ley dice que la fuerza que actúa sobre un cuerpo es directamente proporcional a su aceleración.  Es decir, si sobre un cuerpo actúa una fuerza, dicho cuerpo modificará su velocidad, es decir, adquirirá una aceleración. Dicha fuerza y su aceleración generada son proporcionales y están relacionadas mediante:  F=m*a donde F es la fuerza aplicada, m es la masa del cuerpo sobre el que se aplica la fuerza y a es la aceleración adquirida por dicho cuerpo.Tercera ley o Principio de acción-reacción : Esta ley expresa que cuando un cuerpo ejerce una fuerza sobre otro, éste ejerce sobre el primero una fuerza igual y de sentido opuesto.

Entonces, la Ley de atracción no pertenece a los tres principios de Newton.

What happens to the gravitational force between two objects as the bodies become closer to each other? A. The gravitational force begins to repel the objects. B. The gravitational force increases. C. The gravitational force decreases. D. The gravitational force stays the same.

Answers

Answer:

Explanation:

The gravitational force between two objects becomes weaker if the two objects are moved apart and stronger if they are brought closer together; that is, the force depends on the distance between the objects.

The gravitational force between two objects as the bodies become closer to each other increases.

Gravitational force is force of attraction between two masses. Gravitational force(F) between two bodies is directly proportion to the product of masses(m₁,m₂) of two bodies and inversely proportional to square of distance(r) between them. mathematically it is written as,

F ∝ m₁.m₂

F ∝ 1/r²

F = G m₁,m₂÷r²

where G is gravitational constant, whose value is 6.6743 × 10⁻¹¹ m³ kg-1s⁻².

Force is expressed in Newton N in SI unit. its dimensions are [M¹L¹T⁻²].

As distance decreases the Force increases

A train is travelling at 15 m/s. It accelerates at 3 m/s² for 20 seconds. How far does the train travel in this time?

Answers

The distance traveled by the train is 900 m.

The given parameters:

Initial velocity of the train, u = 15 m/sAcceleration of the train, a = 3 m/s²Time of motion, t = 20 s

What is distance?Distance is a scalar quantity that shows the total path covered by an object.

The distance traveled by the train is calculated as follows;

[tex]s = ut + \frac{1}{2} at^2\\\\s = (15 \times 20) + (0.5 \times 3 \times 20^2)\\\\s = 900 \ m[/tex]

Thus, the distance traveled by the train is 900 m.

Learn more about distance here: https://brainly.com/question/23848540

Answer:

900m

Explanation:

Use the equation: acceleration (a) = change in velocity (v – u) / time taken (t)

Rearrange to solve for the final velocity (v):

v = u + at

Substitute in values and solve:

v = 15 m/s + 3 m/s2 × 20 s = 75 m/s

Rearrange the equation for uniform acceleration (v2 – u2 = 2as) to solve for distance (s):

s = (v2 – u2) / 2a

s = ((75 m/s)2 – (15 m/s)2) / (2 × 3 m/s2)

s = (5,625 m2/s2 – 225 m2/s2) / 6 m/s2

s = 5400 m2/s2 / 6 m/s2

s = 900 m

Two students are discussing gravity. One student says that there is a gravitational attraction between the two
of them. The other student thinks this cannot be true, because he cannot feel any gravitational attraction to
the other student. Which student is correct, and why?

Answers

The first student is correct, even though the force of gravity between them is not noticeable at all. All masses in the universe have a gravitational force of attraction- we feel the gravitational force of the earth because the earth has a very large amount of mass. The gravitational force between the two students is there, but it is a very very very small amount of force. Just because you can’t feel it doesn’t mean it’s not there. Hope that explanation helps! :)

The student says that there is a gravitational attraction between the two of them. This student is correct.

What is gravitational force?

The force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them, according to Newton's universal law of gravitation.

The gravitational force is weak unless there are massive masses involved. As compared to Earth, humans have relatively low masses, which results in a very small and negligible gravitational force. As a result, although it is tiny and imperceptible, gravitational force exists between two people seated near to one another.

Hence, the student, who says that there is a gravitational attraction between the two of them, is correct.

A player kicks a football from ground level with a velocity of
magnitude 27.0 m/s at an angle of 30° above the horizontal.
What is the horizontal distance the ball travels?
(hint: d= 1/2 at^2)

Answers

Answer:

37.33m

Explanation:

To calculate the distance using d= 1/2 at², the time taken for this projectile object (ball) must be calculated.

Time of a projectile = 2u sinθ/ g

Where u = velocity = 27m/s

g = 9.8m/s²

θ = 30°

T = 2usinθ/ g

T = 2 × 27 × sin 30°/9.8

T = 54sin30°/9.8

T = 27/9.8

T = 2.755

T = 2.76s

If the time taken for the ball to move is 2.76s, the distance travelled is:

D = 1/2at²

D = 1/2 × 9.8 × 2.76²

D = 1/2 × 9.8 × 7.6176

D = 74.65248/2

D = 37.33m

The horizontal distance the ball travels is 37.33m

The horizontal distance travel by ball is 37.32 meters.

First we have to calculate time of projectile,

               [tex]Time=\frac{2usin\theta}{g}[/tex]

Where g is acceleration due to gravity and u is velocity.

Given that, [tex]u=27m/s, \theta=30[/tex]

Substitute values in above relation.

       [tex]Time=\frac{2*27*sin30}{9.8}=\frac{2*27*0.5}{9.8}=2.76s[/tex]

The horizontal distance is given by,

              [tex]d=\frac{1}{2}gt^{2}\\ \\ d=\frac{1}{2}*9.8*(2.76)^{2} \\\\d=37.32m[/tex]

A skydiver jumps from a plane and falls for 5 seconds before reaching his terminal velocity. During this 5 seconds interval, describe his acceleration before reaching terminal velocity?

Answers

Answer:

His acceleration during the first five seconds before reaching terminal velocity = (W - D)/m

Explanation:

The terminal velocity is the maximum steady velocity attained by a body falling freely with increasing velocity from rest in a fluid, such as air or water

The net force, F acting on the body falling through the fluid is given as follows;

F = Weight force, W, from gravity - Drag force, D, from the fluid

F = W - D

Given that F = Mass, m × Acceleration, a, we have;

F = m × a

The acceleration, a = F/m = (W - D)/m

His acceleration during the first five seconds before reaching terminal velocity = (W - D)/m.

When the energy of a wave increases, what happens to the amplitude?

Answers

Answer:

The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy.

Explanation:

When the energy of a wave increases, the amplitude also increases. This is because the amplitude of the wave is directly proportional to the energy of a wave.

What is the amplitude of a wave?

The amplitude of a wave may be defined as the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.

It is the principle of physics that when the amplitude of the wave is higher, the energy also gets higher. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.

Therefore, when the energy of a wave increases, the amplitude also increases. This is because the amplitude of the wave is directly proportional to the energy of a wave.
