What type of reaction is below?

Answer:

=57600joules

Explanation:

Given data

Velocity =0.8m/s

Time = 30*60=1800 seconds

Distance =Velocity x time

Distance =0.8*1800

Distance =1440m

Work done = force x distance

Work done =40*1440

Work done =57600joules

Hence the work Done is 57600joules

Answer:

Option C, Both the basketball's speed and direction would change

Explanation:

When two objects travelling with certain speed interact with each their internal forces changes and hence their motion changes simultaneously.

In general cases it is said that momentum is conserved. Momentum is nothing but just the product of mass and velocity.

As the motion of the football changes, then momentum also changes. Since mass is a constant value, it is the velocity of the football that changes.

Hence, both speed and direction of both the football changes.

Option C is correct

Answer:

amplitude

Explanation:

amplitude of a wave is the maximum displacement of a point from its rest position.

Answer:

Explanation:

Initial momentum = 30 kg m/s .

impulse on the object = 10 N s towards west . = - 10 Ns

impulse = change in momentum

Let velocity after impulse be v

momentum after impulse = 6 v

change in momentum = 6v - 30

So

- 10 = 6v - 30

20 = 6v

v = 3.33 m /s

Since the velocity is positive , that means it is moving in the same direction as earlier .

Answer: b

Explanation:

Laura will increase the force she needs. When Laura puts her file cabinet on a small cart with wheels, the cart will experience less friction compared to the file cabinet directly resting on the ground. The correct answer is option D.

The presence of wheels reduces the contact area between the cart and the ground, leading to lower frictional forces. As a result, it becomes easier for the cart to move. However, the file cabinet still possesses its original mass, so to accelerate the cart (and the cabinet) to a certain speed or maintain a constant velocity, Laura will need to exert a greater force on the cart due to the reduction in friction. Therefore, the correct answer is D - Laura will increase the force she needs.

Answer:

F = 12.52 N

Explanation:

Given that,

Charge, q₁ = -2 C

Charge, q₂ = 5 C

The distance between charges, d = 84,752 m

We need to find the force between the two charges. The force between two charges is given by :

[tex]F=k\dfrac{q_1q_2}{d^2}\\\\F=9\times 10^9\times \dfrac{2\times 5}{(84752)^2}\\F=12.52\ N[/tex]

So, the force between charges is 12.52 N.

formula: m1 * d1 = m2 * d2

datos:

m1= 45 kg

d1= 160 cm

m2= 38 kg

d2= x

reemplazamos datos en formula:

45kg * 160cm = 38kg * d2

El 38 pasa al otro lado de la igualdad a dividir:

(45kg * 160cm) / 38 kg = d2

Resolvemos: (kg se cancela con kg, quedando solo los cm)

7200cm / 38 = d2

Resultado:

d2 = 189.5 cm

Respuesta: La condición que se debe cumplir es que la distancia del centro al niño de la derecha sea de 189.5cm

Answer:

Metal paper clips do not attract or repel each other. When an electromagnet is placed nearby, the paper clips can be observed to move toward it. Which statement describes this phenomenon?

- Magnetic domains within the paper clips align with the magnetic field.

An electromagnet is built using a 9-volt battery with conducting wire connected to a switch and coiled around an iron nail. A pile of metal paper clips is moved close to the iron nail, yet no attraction is apparent between the electromagnet and the paper clips. What is the most likely conclusion to explain this result?

- The switch is turned off.

An experiment modeled the interaction between magnetic force and the change of energy of an object influenced by the magnetic force. The experiment’s researchers observed that the metal wheels of a small car turned as they experienced the force exerted by a magnetic field, drawing the car closer to the magnet. What energy is being gained by the car?

- Kinetic Energy

Which statement about the current and magnetic field correctly describes this figure as well as all electromagnets?                                    

- The current generates and is perpendicular to the magnetic field.

Domains are the regions in a material in which the magnetic fields of many of the atoms are aligned facing the same direction. What is the relationship between the electrical current and the alignment of atoms responding to the current?

- As current increases, the alignment becomes more organized.

A to B in the graph shows the object going at the fastest speed.

In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

"The rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude."

Explanation:

Answer:

The force that pulls the car down is Wₓ = 14052.6 N and the one that pushes the car up is F = 26552.6 N

Explanation:

For this exercise we will use Newton's second law, let's set a reference system where the x axis is parallel to the plane, in the adjoint we can see the forces in the system.

           sin  35 = Wₓ / W

            cos 35 = W_y / W

            Wₓ = W sin 35

            W_y = W cos 35

            Wₓ = 2500 9.8 sin 35

             Wₓ = 14052.6 N

let's write the equations for each axis

and

Y axis  

       N-W_y = 0

       N = W_y

X axis  

       F -Wₓ = m a

       F = Wₓ + m a = mg sin 35 + m a

       F = m (a + g sin 35)

let's calculate

       F = 2500 (5 + 9.8 sin 35)

       F = 26552.6 N

The force that pulls the car down is Wₓ = 14052.6 N and the one that pushes the car up is F = 26552.6 N

It is a true statement that the idea that all matter consists of elements was first introduced a few hundred years ago.

Anything which has mass and occupies space is known as matter, mainly there are four states of matter solid liquid gas, and plasma.

These different states of matter have different characteristics according to which they vary their volume and shape.

Individuals have believed that earth, air, water, and fire are the only four elements that make up matter for roughly two thousand years.

For more than two thousand years, Aristotle's theory that all matter is composed of just four elements was accepted, but only around 500 years ago did scientists begin to find all of the elements that are currently recognized.

Beginning around five hundred years ago, scientists started learning about all of the elements that are currently recognized.

Answer:

They must have the same units when expressed in base units

Explanation:

Too add any two values together you need them to be in the same units. but You can convert diffrent units of the same messure to each other in order to achive this; ie you can add meeters to feet if you multiply the meters by 3.28 but you can't add mass and length together.

With the concept of  pattern we find that the answer for the sum of physical magnitudes is:

They must have the same units when expressed in base units.

To add two phsical quantities to meet some requirements:

* Must be of the same type

* Must be in the same base units

That they have the same type implies that we cannot add length with time or masses, length or speeds must be added with their pairs

The use of the same base unit guarantees that we use the same pattern, or that we must reduce the magnitudes to the same pattern, for example: we cannot add meters with inches directly, we must reduce inches to meters, which is the unit of the international system.

International System  it guarantees the existence of common and reproducible patterns for all physical quantities.

Add two phsical quantities, the correct answer is:

must have the same units in base units

In conclusion, the measurement system and units allows adding magnitude of the same type with the same units of a base unit or standard.
