EXPLANATION OF THE CORRECT ANSWER

According to Paul Tippens, to add vectors using the parallelogram method, the following steps must be followed:
1. Change of scale in the vectors
2. Vectors come from the same point, called the origin, so the vectors are collinear
3. Draw parallel lines, in each vector forming a parallelogram
4. To find the resulting vector, draw a line from the origin to the intersection of parallel lines

EXPLANATION OF THE CORRECT ANSWER

According to Douglas C. Giancoli's physics book, the correct data is:

EXPLANATION OF THE CORRECT ANSWER

To convert the speed into km/ham/s, the following formula is used:
km/h =(85 km/h)(1 h/3600 s)(1000 m/1 km)
23.61 m / s

EXPLANATION OF THE CORRECT ANSWER

According to Newton's second law, whenever a body describes a circular path, the centripetal force is given, at each instant, by the resultant of the forces acting on the body in the direction of the radius of the path.

EXPLANATION OF THE CORRECT ANSWER

The equations according to the movement we are talking about are the following:

EXPLANATION OF THE CORRECT ANSWER

Because the rope remains horizontal and there is no friction, the Y axis does not need to be analyzed. Then, according to Newton's second law:

EXPLANATION OF THE CORRECT ANSWER

Using the formula:

EXPLANATION OF THE CORRECT ANSWER

According to Newton's second law, it states that F = ma, so that to =

Substituting figures we have:

EXPLANATION OF THE CORRECT ANSWER

The speed of the body is constant so its acceleration is zero. To calculate the coefficient of friction, the Normal N must be calculated

EXPLANATION OF THE CORRECT ANSWER

According to Douglas C. Giancoli's physics book, the correct data is:

According to Douglas C. Giancoli's physics book, the correct data is:

EXPLANATION OF THE CORRECT ANSWER

Statics is the branch of physics that deals with the calculation of the forces that act on and within structures that are in equilibrium.

EXPLANATION OF THE CORRECT ANSWER

Power, where:

Work is where:

T = Work
F = Newton Force
d = Distance in meters

= cosine of the angle between the force applied and the direction of displacement.

Force F = ma where
F=Force
m = Mass
a = Acceleration

Density , where:

p =Density
m = Mass
V = Volume

EXPLANATION OF THE CORRECT ANSWER

Condensation is the physical process in which a substance in gaseous form turns into liquid form. This phase change generates a certain amount of energy called latent heat.

EXPLANATION OF THE CORRECT ANSWER

Sublimation is the process in which solid matter passes into the gaseous state without passing through the liquid state.

EXPLANATION OF THE CORRECT ANSWER

Considering that the formula to determine the volume is:

v = length x width x height

Because it is at 80% of its capacity, we have:

EXPLANATION OF THE CORRECT ANSWER

If the density is and the problem indicates that the dimensions of the cube are reduced, the density increases if the same initial mass is conserved. The edges are reduced by half so that:

L' = L/2, then the volume of the cube will now be:

In this way the new density is:

It is eight times the original density which is:

EXPLANATION OF THE CORRECT ANSWER

The problem provides a mass, but the force data is needed to be able to perform the calculations, so we multiply the mass by the action of the acceleration of gravity to obtain the weight, which is finally a force.

From Hook's law we have:

EXPLANATION OF THE CORRECT ANSWER

If we have the mass, it is possible to calculate the weight, that is, the force exerted:

EXPLANATION OF THE CORRECT ANSWER

According to the book General Physics by Héctor Pérez Montiel:
The equation that represents Pascal's principle is:

The equation that represents Archimedes' principle:

The equation that represents the specific weight:

The equation that represents weight:

W = mg

The units in which weight is measured in the SI.

EXPLANATION OF THE CORRECT ANSWER

Thermodynamics is the part of physics that studies heat transfer, energy conversion, and the ability of systems to produce work. The laws of thermodynamics explain the global behaviors of macroscopic systems in equilibrium situations.

EXPLANATION OF THE CORRECT ANSWER

Applying the formula to convert degrees Celsius to degrees Fahrenheit we have:

EXPLANATION OF THE CORRECT ANSWER

Applying the fundamental formula of calorimetry we have:

Where:
Q = amount of heat
m = body mass
c = specific body heat

temperature variation

To calculate the temperature you have:

EXPLANATION OF THE CORRECT ANSWER

Applying the fundamental formula of calorimetry we have:

Where:
Q = amount of heat
m = body mass
c = specific body heat

temperature variation
To determine the amount of heat we have:

EXPLANATION OF THE CORRECT ANSWER

The first law of thermodynamics indicates that in a process, energy is neither created nor destroyed, but is conserved.

EXPLANATION OF THE CORRECT ANSWER

The second law of thermodynamics indicates that when a thermodynamic process occurs, it occurs in a single direction with respect to time, but not vice versa.

EXPLANATION OF THE CORRECT ANSWER

According to the first law of thermodynamics we have:

Where:

First we convert the 700 calories into Joules to work according to the International System.

EXPLANATION OF THE CORRECT ANSWER

According to the problem data:

EXPLANATION OF THE CORRECT ANSWER

Conductors are the elements that allow or facilitate the passage of electric current because some of the electrons are loosely attached to the nucleus and can move freely inside the material (even when they cannot leave the object easily. ). These electrons are often known as free electrons or conduction electrons.

EXPLANATION OF THE CORRECT ANSWER

According to Ohm's law, we have:

Substituting values ​​we have:

EXPLANATION OF THE CORRECT ANSWER

Based on Coulomb's law, we have:

Where:

EXPLANATION OF THE CORRECT ANSWER

Taking into account that the signs of the charges do not influence the result of the force between them, but only indicate whether it is attraction or repulsion, Coulomb's law indicates: “The magnitude of each of the electric forces with that two point charges interact at rest is directly proportional to the product of the magnitude of both charges and inversely proportional to the square of the distance that separates them.”

EXPLANATION OF THE CORRECT ANSWER

According to Douglas C. Giancoli's book, the circuit diagrams are as follows:

EXPLANATION OF THE CORRECT ANSWER

Since the three resistances are completely in parallel, we apply the formula for adding resistances in parallel:

EXPLANATION OF THE CORRECT ANSWER

Ampere's law relates the magnetic field and the electric current of a conductor in different arrangements. In two parallel conductors, if the current has the same direction and direction, an attractive force is generated between both conductors.
