Answer:  O furo diminui enquanto a chapa aumenta a sua dimensão.

(The diameter decreases and the dimensions of the metal increases)

Explanation:

I will answer in English:

Here we have a piece of metal with a small hole on it, that is heated in a hoven.

We know that when a piece of metal is heated, it will expand (the density decreases, so the dimensions of the piece of metal increase).

Now, particularly, the hole will also expand but inwards, as each "extreme" of the piece of metal, will expand into where it has less resistance, so it will expand in the region where there is no material. This "inwards" expansion is why the diameter of the hole will decrease.

Answer:

for the time period 0 to 2s distance= 2m

for the time period 2s to 5s distance = 4.5m

Explanation:

for the time period 0 to 2s

s = (v+u)t/2

s= (2+0)×2/2

s = 2m

for the time period 2s to 5s

s = (v+u)t/2

s= (1+2)×3/2

s= 4.5m

From the The velocity-time graph for an ice skater is shown in Figure ,

The distances covered by the skater between 0 s and 2 s is 2 meters

The distance covered by the skater between 2 s and 5 s is 6.25 meters

The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object. The unit of velocity is meter/second. It can also be represented by the infinitesimal rate of change of displacement with respect to time. The generally considered unit for velocity is a meter per second.

As we know that slope of the velocity time curve represents the acceleration of the object while the area under the velocity time curve represents the displacement covered by the object

As given in the problem The velocity-time graph for an ice skater is shown in Figure

the distance covered by the skater between 0 s and 2 s is

The area of the triangle formed between 0 s and 2 s

Distance = 1/2 ×2×2

              = 2 meters

Similarly, the distance covered by the skater between 2 s and 5 s is the area of the quadrilateral formed between 2 s and 5 s

Distance between 2 s and 5 s = area of the quadrilateral

Area of the quadrilateral = area of the square between 2s and 4s + area of the triangle between 2 s and 4 s + area of the triangle between 4 s and 5 s + area of the square between 4 s and 5 s

= 2×2 + 1/2 ×2×1/2 + 1/2 ×1×3/2 + 1×1

=4 + 1/2 + 3/4 +1

=6.25 meters

Thus, The skater travels a distance of 2 meters between 0 and 2 seconds and The skater travels 6.25 meters between seconds 2 and 5.

Answer:

The work is done by the force 100 NM.

Explanation:

=5kg * 2 m/s^2

=5* 2 N (kg*m/s^2=N)

=10N

Work done = force* distance

=10N* 10

= 100 NM

For an object of mass 5 kg accelerating at the rate of 2 m/s², then the work done by the force on the object will be 100 Nm.

In physics, the word "work" involves the measurement of energy transfer that takes place when an item is moved over a range by an externally applied, at least a portion of which is applied within the direction of the displacement.

The length of the path is multiplied by the element of a force acting all along the path to calculate work if the force is constant. The work W is theoretically equivalent towards the force f times the length d, or W = fd, to portray this concept.

As per the given information in the question,

Answer: Ball #1

Explanation:

Since the platform is more inclined, it will allow the ball to roll down faster.

The direction of the magnetic field that allows a conducting wire to levitate is a magnetic field pointing directly downward.

When a conducting wire carries current and is placed in an external magnetic field, it experiences a force known as the Lorentz force. The Lorentz force on a current-carrying wire is given by the equation:

F = I * L * B * sin(theta)

Where:

- F is the force on the wire

- I is the current flowing through the wire

- L is the length of the wire

- B is the strength of the magnetic field

- theta is the angle between the wire and the magnetic field

For the wire to levitate, the force on the wire should be equal to the force due to gravity, but in the opposite direction. In other words, the upward force on the wire should counterbalance the downward force of gravity.

Since the current in the wire is flowing directly upward, the force on the wire due to the external magnetic field should also be pointing directly downward to achieve levitation. This means that the magnetic field should be perpendicular to the wire and pointing directly downward.

To allow a conducting wire carrying current directly up to levitate, the external magnetic field must be perpendicular to the wire and pointing directly downward.

The minimum momentum of the photon required for the photoproduction of kaons in the center of mass is approximately 570 MeV/c.

The minimum momentum required for the photoproduction of kaons in the center of mass can be determined using the conservation of energy and momentum. In this reaction, a photon collides with a proton to produce a kaon and a residual nucleus. Assuming that the proton is initially at rest, the minimum momentum of the photon required for this reaction to go in the center of mass can be calculated using the energy-momentum relation: E^2 = p^2c^2 + m^2c^4

where E is the energy of the photon, p is its momentum, c is the speed of light, and m is the rest mass of the proton. The energy of the photon required to produce a kaon with a mass of approximately 500 MeV/c^2 can be estimated as follows: E = m(K) + m(p) - m(nucleus)
Assuming that the residual nucleus has a mass equal to that of the original proton, we get:
E = 500 + 938 - 938 = 500 MeV

Substituting this value of E into the energy-momentum relation and solving for p, we get:
p = sqrt(E^2/c^2 - m^2c^2) = 570 MeV/c

Explanation:

When the output does not meet the equilibrium quantity in a market, a situation known as disequilibrium occurs. Disequilibrium refers to a state where there is an imbalance between the quantity demanded and the quantity supplied of a particular good or service. In this situation, two possibilities can arise: Excess Demand and Excess Supply.

Excess Demand: If the quantity demanded exceeds the quantity supplied, it creates a situation of excess demand or a shortage. Consumers are willing to purchase more of the product at the prevailing price than what is available in the market. This can lead to increased competition among consumers, rising prices, and a potential loss of potential sales for suppliers.

Excess Supply: On the other hand, if the quantity supplied exceeds the quantity demanded, it creates a situation of excess supply or surplus. Suppliers are producing more of the product than what consumers are willing to purchase at the prevailing price. This can lead to price reductions, decreased profitability for suppliers, and a buildup of unsold inventory.

In either case, the market is not in equilibrium, and there is a discrepancy between the quantity demanded and the quantity supplied. In response to disequilibrium, market forces such as price adjustments, changes in consumer behavior, or shifts in production levels may occur in an attempt to restore equilibrium.
