Comenzemos con unas definiciones.
La posición nos dice la ubicación espacial de un dado objeto.
La velocidad nos dice como cambia la posición a medida que pasa el tiempo.
La aceleración nos dice como cambia la velocidad a medida que pasa el tiempo.
Teniendo esto en cuenta, la respuesta correcta La respuesta correcta es la opción C: "Las posiciones son las mismas"
Para poder entender esto, podemos desarrollar:
Ahora, supongamos un ejemplo.
Sea una persona caminando y un auto yendo en la misma dirección, de tal forma que la persona comienza varios metros delante del auto.
A medida que el auto aumenta su velocidad, eventualmente se encontrara al lado de la persona.
Naturalmente, es fácil darse cuenta de que tanto la velocidad como la aceleración del auto serán mayores que las de la persona, pero la posición (almenos en una dimensión) será la misma.
Podemos interpolar esto a cualquier situación similar, sabemos que para dos objetos que estén al lado del otro la posición será la misma, pero sin más contexto no podemos concluir nada sobre la relación entre las velocidades y las aceleraciones.
Con esto en mente, la respuesta correcta es la opción C: "Las posiciones son las mismas"

In a collision, the human body will strike the seatbelt, steering wheel, dash or windshield at? Group of answer choices only 10 to 15 miles per hour the same speed as the vehicle twice the speed of the vehicle one half the speed of the vehicle
Answer:
isn't this kinda like math
Explanation:
In a collision, the human body will strike the seatbelt, steering wheel, dash, or windshield at the same speed as the vehicle.
A collision is when one object comes in contact with another, leading to an abrupt and forceful impact. This means that a collision happens when one object hits another surface or object with an extreme impact that causes injuries or damages.
There are three theories of collision, among which the "human collision" is the second theory. In this theory, the impact of a collision between the human body and the external surface happens after the collision occurs. But the force of the impact remains the same, meaning the force with which the body hits the other surface is at the same speed as the vehicle prior to the collision. This is because while the collision may have occurred, the body is still moving at the same speed as the vehicle, thereby resulting in the same speed of the vehicle as that of the force of impact. So, the human body will strike the external or opposite surface at the speed of the vehicle.Prior to a collision, the body inside the vehicle is moving at the speed of the vehicle. So, when a collision occurs, the body continues to move with that speed even though the vehicle may have halted. Thus, the human body will strike at the same speed as the vehicle.

A television weighs 8.50 pounds. How many grams is this? (Hint: You need to
use two unit conversion fractions. 1 pound equals about 0.454 kg.)
A. 3860 g
B. 18.7 g
C. 18,700 g
D. 3.86 g
SUBWT
C. 18,700g
Explanation:
8.50+1
then -0.454
The television weighs 8.50 pounds which is equal to 3860 grams. Hence, option (A) is correct.
What is mass?In physics, mass is a numerical representation of inertia, a fundamental characteristic of all matter. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force.
The change caused by an applied force is smaller the more mass a body has. The kilograms serves as the unit of mass in the International System of Units (SI).
Given that: A television weighs 8.50 pounds.
And 1 pound equals about 0.454 kg.
Hence, the television weighs = 8.50 pounds × (0.454 kg/1 pound).
= 3.859 kg.
Hence, the television weighs = 3.859 kg × (1000 g/1kg).
= 3859 grams
= 3860 grams ( approx.)
Hence, the television weighs 3860 grams.

what is the shape of the line graph that shows the temperature change over time of the liquid before it starts to boil?
The line graph showing the temperature change over time of a liquid before it boils has an upward-sloping trend as heat is applied until it reaches its boiling point, with fluctuations due to heat transfer rate changes.
What is the heat transfer rate?Heat transfer rate refers to the amount of heat energy transferred per unit of time between two objects or substances that are at different temperatures. It is a measure of how quickly heat is transferred between two objects or substances and is influenced by factors such as the temperature difference between the objects, the thermal conductivity of the materials, the surface area in contact, and the type of heat transfer mechanism involved (conduction, convection, or radiation). Heat transfer rate is often expressed in units of watts or BTUs per unit of time (e.g., watts/second or BTUs/hour).
Here in the Question,
The shape of the line graph that shows the temperature change over time of the liquid before it starts to boil is generally an upward-sloping line. As heat is applied to the liquid, its temperature will increase gradually until it reaches its boiling point. The rate of temperature increase may not be constant, and there may be some fluctuations due to factors such as changes in the rate of heat transfer.
Therefore, the trend of the line graph will be upward-sloping until the liquid reaches its boiling point.

an object is sliding down in clean plane the velocity change at a constant rate from 10 cm to 15 CM in 2 second what is it acceleration ?
Initial velocity=10m/s=u
Final velocity=v=15m/s
Time=t=2s
[tex]\boxed{\sf Acceleration=\dfrac{v-u}{t}}[/tex]
[tex]\\ \sf\longmapsto Acceleration=\dfrac{15-10}{2}[/tex]
[tex]\\ \sf\longmapsto Acceleration=\dfrac{5}{2}[/tex]
[tex]\\ \sf\longmapsto Acceleration=2.5m/s^2[/tex]
Answer: a = 2.5 cm/s²
Explanation:
Acceleration = (Final velocity - Initial Velocity)/time taken
a = v-u/t
Initial velocity = 10 cm/s
Final velocity = 15 cm/s
Time = 2 seconds
a = (15-10)/2
a = 5/2
a = 2.5 cm/s²
Therefore the acceleration is 2.5 cm/s²

The tin can with water in its bottom is heated to boil water and the steam is allowed to escape for some time. The open mouth is sealed with an air-tight cap and cooled under tap water. The tin can get crushed, why?
Explanation:
Water does expand with heat (and contract with cooling), but the amount of expansion is pretty small. So when you boil a can filled with water and seal it, the water will contract slightly as it cools. The can may kink slightly, but that will be it. Actually, most likely the only things you will be able to see is then top and bottom will be sucked in and go concave. Just like a commercial can of beans.
Now if you have a can with a little water and a big air space, things are completely different.
As the water boils, water vapour is given off. Steam. Let it boils for a minute just to make sure (nearly) all the air is expelled and the can is filled with steam.
Now when you put the lid on and cool the can, that steam condenses back to water, and goes from filling the can to a few drops of water. The can is now filled (if that is the right word) with a near vacuum, The air pressure, 15 lbs/square inch, will be pressing on every surface of the can, with nothing inside the can to resist it.
The can will crumple before your eyes.
Non-ideal behavior for a gas is most likely to be observed under conditions of a) high pressure and low temperature. b) high temperature and high pressure. c) high temperature and low pressure. d) standard temperature and pressure. e) low temperature and low pressure.
Answer:
high temperature and low pressure
Explanation:
Real gases have intermolecular forces of attraction between them hence they can be liquified. However, gases approach ideal behavior at high temperature and low pressure.
According to the kinetic theory of gases, gases molecules move at incredibly high speeds and exhibit no intermolecular interaction because the gas molecules are isolated from each other.
At high temperature and low pressure, gas molecules are found to possess maximum kinetic energy. They move with a very high velocity and have minimal intermolecular interaction between them in accordance with the proposition of the kinetic theory of gases.
