En el proceso de diseño de ingeniería, ¿qué limitaciones deben tenerse en cuenta al utilizar un modelo / prototipo?
Answer:
Las limitaciones de un modelo o prototipo son;
1) Los parámetros ambientales (donde se opera el modelo, prototipo o producto) son diferentes y, por lo tanto, pueden producir relaciones y factores ambientales que serán diferentes de los factores ambientales y las relaciones del objeto real.
2) El análisis del problema puede ser inadecuado
3) La posibilidad de falta de satisfacción del cliente con un modelo, preferencia por la demostración real del producto.
4) Reproducción inexacta del entorno del producto durante la prueba del modelo
5) El factor de costo del modelo
6) Mayor complejidad introducida por el modelo / prototipo al análisis de la solución
Explanation:
El modelo o prototipo es la presentación del diseño articulado, construido para demostrar el producto real con el propósito de encontrar la existencia de errores en el diseño que serían corregidos, antes de que se realice la producción real

inertia is a force whuch keeps stationary object at rest and moving objects in motion is it trur?
Answer:
True
Explanation:
Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them

which forces are capable of affecting particles or objects from large distance
Answer:
only long-range force that affects all particles is the gravitational force.
Explanation:
In nature there are four fundamental forces: nuclear, weak, gravitational and electrical.
The last two are long-range, that is, the forces are zero for infinite distances, the current gravitational on all the particles and the electric one acts on the charged particles, without the chosen charge it is zero, the forces is also zero.
Consequently the only long-range force that affects all particles is the gravitational force.

Answer:
Light passes through the gas
Light passes through the pure water
Light passes through some solids
Explanation:
In gasses, there are many spaces between the molecules. These spaces allow light to pass through them without any interruption.
In pure water, there are some spaces between particles. these particles allow some light rays to pass theough, some to move through the common boundary and reflec5 some of them.

4×10⁻³ . . . . matches choice D

Additional comment
This is physics, not math. In the physical sciences, most numbers must be considered to be measurements. (A few are definitions.) Hence, the rules of significant figures and precision apply to the results of arithmetic operations. This problem is a good illustration of what happens when computing small differences of large numbers. We start with 3 significant figures in 0.205, and end up with 1 significant figure in 0.004.
Scientists have developed a new type of solar cell with an efficiency of over 40 %.
The efficiency of the solar cell was confirmed independently by other scientists.
Suggest why it was important to confirm the efficiency independently.
Answer:
According to Carl Sagan's Baloney Detection Kit notes
"Whenever possible there must be independent confirmation of the facts"
Independent confirmation by other scientist is to ensure that the observation of the over 40% efficient solar panel is repeatable
It is also important to avoid accepting the given mandates at face value and accepting that the scientist considered all factors when taking the results or that the original developers has assigned others to check their findings before the introduction of the new type of solar cell

A square wooden raft floats on a lake. The density of the water in the lake is 1000 kg/m². The sides of the raft are 2.0m long and the thickness of the raft is 0.20 m. The mass of the raft is 700 kg. How many barrels, each of mass 100 kg, could be placed on the raft before its surface sinks to the surface of the water?
Answer:
1
Explanation:
V=2*2*0.2=0.8m^3
d=m/v 1000*0.8=800kg
800=700+100(n) (n for barrels)
n=1
This question deals with the concept of buoyancy. This can be solved by calculating the buoyant force.
"1" barrels, each of mass 100 kg, could be placed on the raft before it sinks to the surface water.
First, we need to calculate the buoyant force on the raft due to water. This force is equal to the weight of the volume of water equal to the volume of the raft.
Buoyant Force = (Volume of Raft)(Density of Water)(g)
Buoyant Force = [(2 m)(2 m)(0.2 m)][1000 kg/m³](9.81 m/s²)
Buoyant Force = (0.8 m³)(1000 kg/m³)(9.81 m/s²)
Buoyant Force = 7848 N
For the raft to sink the weight of the raft combined with the weight of barrels must exceed the buoyant force. Now, we will calculate the weight of raft and barrels and equate it with the buoyant force.
[Mass of Raft + (No. of Barrels)(Mass of 1 Barrel)][g] = Buoyant Force
[700 kg + (No. of Barrels)(100 kg)][9.81 m/s²] = 7848 N
(No. of Barrels)(981 N) = 7848 N - 6867 N
[tex]No. of Barrels = \frac{981\ N}{981\ N}[/tex]
No. of Barrels = 1

a car starts from rest & acquire a velocity of 54km/h in 2 sec. Find-
a) the acceleration
b) distance traveled by car assume motion of car is uniform
c) if the mass of the car is 1000kg. what is the force acting on it?
Pls help me. I'm bad in this subject. kinda need it by today
Answer:
a. Acceleration, a = 7.5 m/s
b. Distance, S = 15 meters
c. Force = 7500 Newton
Explanation:
Given the following data;
Mass = 1000 kg
Initial velocity = 0 m/s (since it's starting from rest).
Final velocity = 54 km/h
Time = 2 secs
Conversion:
54 km/h to m/s = 54*1000/3600 = 15 m/s
a. To find the following acceleration;
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{initial speed - final speed}{time}[/tex]
Substituting into the formula, we have;
[tex] Acceleration = \frac{15 - 0}{2}[/tex]
[tex] Acceleration = \frac{15}{2}[/tex]
Acceleration, a = 7.5 m/s
b. To find the distance, we would use the second equation of motion.
[tex] S = ut + \frac {1}{2}at^{2}[/tex]
Where;
S represents the displacement or height measured in meters. u represents the initial velocity measured in meters per seconds. t represents the time measured in seconds. a represents acceleration measured in meters per seconds square.Substituting into the equation, we have;
[tex] S = 0*2 + \frac {1}{2}*(7.5)*2^{2}[/tex]
[tex] S = 0 + 3.75*4[/tex]
[tex] S = 15 [/tex]
Distance, S = 15 meters
c. To find the force, we would use the following formula;
[tex] Force = mass * acceleration [/tex]
[tex] Force = 1000 * 7.5 [/tex]
Force = 7500 Newton

A college dorm room measures 14 ft wide by 13 ft long by 6 ft high. What is the air in it under normal conditions?
Complete question:
A college dormitory room measures 14 ft wide by 13 ft long by 6 ft high. Weight density of air is 0.07 lbs/ft3. What is the weight of air in it under normal conditions?
Answer:
the weight of the air is 76.44 lbs
Explanation:
Given;
dimension of the dormitory, = 14 ft by 13 ft by 6 ft
density of the air, = 0.07 lbs/ft³
The volume of the air in the dormitory room = 14 ft x 13 ft x 6 ft
= 1092 ft³
The weight of the air = density x volume
= 0.07 lbs/ft³ x 1092 ft³
= 76.44 lbs
Therefore, the weight of the air is 76.44 lbs

Choose an object that is slowing down, one that is speeding up, one that is moving at a constant speed but changing direction, and one that is moving at a constant velocity with zero acceleration.
When the brake is applied to the car and comes to rest after some time is an example of an object that is slowing down.
What is acceleration?The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
1. When the brake is applied to the body and comes to rest after some time is an example of an object that is slowing down.
2. When a person accelerates the car and the velocity is increasing is an example of speeding up.
3. An object moves in a circular motion moving at a constant speed but changing direction,
4. Acceleration is the rate of change of velocity. If the change in the velocity is constant the acceleration is zero is an example of moving at a constant velocity with zero acceleration.
