Fundamentally, pressure is defined as force per unit area. What is the source of the force in a gas sample? A) The force is from gravity acting on the particles. B) The force is composed of the sum of the collisions only between gas molecules. C) The force is composed of the sum of the collisions only between the gas molecules and the container. D) The force is composed of the sum of all collisions--between the gas molecules, each other and the container. E) The force was imparted to the container in its initial filling, a transfer of momentum.
Answer:
Option C
Explanation:
Given
Pressure = Force /Area
For any gas sample, force is defined as basically the force exerted by the gas molecules when they strike the surface (with in which they are contained) and bounce back.
Hence, Option C is the correct
que es el periodo de un pendulo
Answer:
what
Explanation:
Answer:
El periodo del péndulo simple, para oscilaciones de poca amplitud, viene determinado por la longitud del mismo y la gravedad.
Explanation:
No influye la masa del cuerpo que oscila ni la amplitud de la oscilación. Donde: T: Periodo del péndulo.
There is a fixed voltage across a resistor, and you measure a current of c1 A. If you replace the resistor with one that has twice the resistance value, how much current will you measure? a) 0.2 A b) 0.5 A c) 0.8 A d) 1.1 A
Answer:
Option B
Explanation:
Given
The current flowing through the circuit = 1 Ampere
As we know
I is inversely proportional to resistance.
I α 1/r
or I = k/r
If the resistor "r" is replaced by any resistor "R" with resistance = 2r, then the current will be
I = 1/2 of 1 ampere
I = 0.5 Ampere
Hence, option B is correct
sheet of paper and a ball having same mass are dropped from the same height and obviously paper balls faster than a sheet of paper. what conclusion can be drawn from this acticity?
Answer:
In free fall, all items will fall at the same time. You were told that they have the same mass hence g×t which is constant.According to the law of universal gravitation, any two objects are attracted to each other. The strength of the gravitational force depends on the masses of the objects and their distance from each other.
Many stars have planets around them. If there were no gravity attracting a planet to its star, the planet's motion would carry it away from the star. However, when this motion is balanced by the gravitational attraction to the star, the planet orbits the star.
Two solar systems each have a planet the same distance from the star. The planets have the same mass, but Planet A orbits a more massive star than Planet B.
Which of the following statements is true about the planets?
A.
Planet B will keep orbiting its star longer than Planet A.
B.
Planet B is more attracted to its star than Planet A.
C.
Planet A orbits its star faster than Planet B.
D.
Planet A has a longer year than Planet B.
C. Planet A orbits its star faster than Planet B.
Explanation:
since Planet A is closer to the star due to its gravitational force, it will orbit its star faster than planet B

According to the special theory of relativity, what is the fourth dimension?
Explanation:
A four-dimensional space is a mathematical extension of the concept of three-dimensional or 3D space. Three-dimensional space is the simplest possible abstraction of the observation that one only needs three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.
According to the special theory of relativity, the fourth dimension is time. The special theory of relativity, proposed by Albert Einstein in 1905, revolutionized our understanding of space and time.
It states that space and time are interconnected and form a four-dimensional framework known as spacetime. In this framework, three dimensions correspond to space (length, width, and height), and the fourth dimension is time. Einstein's theory introduced the concept of time dilation, which means that time can appear to pass differently for observers in relative motion. This idea challenges the notion of time as an absolute quantity and demonstrates that it is influenced by an observer's relative motion and gravitational fields.
To visualize the fourth dimension, consider a space-time diagram where an object's position in space is plotted against time. Each point on the diagram represents an event, combining its spatial coordinates with the time at which it occurred. This four-dimensional representation allows us to understand the relationship between space and time in a unified framework.

Un tanque de 50 litros tiene un gas a CNPT. ¿Cuánto valdrá la presión si la temperatura aumenta 40 °C, y el volumen permanece constante?
Answer:
La presion a 40 °C es 1.05 atm.
Explanation:
Usando la ecuación ideal de los gases.
[tex]PV=nRT[/tex]
Debemos recordar, que CNPT significa condiciones normales de presión y temperatura.
Para el primer estado tenemos:
[tex]P_{1}V_{1}=nRT_{1}[/tex]
Donde:
P(1) es la presion en el estado incial (1 atm)V(1) es el volumen incial (50 L)T(1) es la temperatura incial (25 °C = 298 K)Para el segundo estado:
[tex]P_{2}V_{2}=nRT_{2}[/tex]
Donde:
P(2) es la presion en el estado final ( x atm)V(2) es el volumen final (50 L)T(2) es la temperatura final (40 °C = 313 K)Como ambas ecuaciones tienen el mismo valor de volumen podemos igualarlas:
[tex]\frac{nRT_{1}}{P_{1}}=\frac{nRT_{2}}{P_{2}}[/tex]
n y R permanecen constantes, se puden cancelar.
[tex]\frac{T_{1}}{P_{1}}=\frac{T_{2}}{P_{2}}[/tex]
Despejamos P(2).
[tex]P_{2}=\frac{P_{1}T_{2}}{T_{1}}[/tex]
[tex]P_{2}=\frac{1*313}{298}[/tex]
[tex]P_{2}=1.05\: atm[/tex]

Describe how an oscilloscope should be used to measure the frequency of the sound wave from the sonometer
Answer:
T = reading (cm) time base (s / cm)
f = 1 / T
Explanation:
An oscilloscope is a piece of equipment that allows you to visualize and measure a wave that reaches you, in the case of having a sonometer this transforms the sound wave into an electrical signal to be introduced through one of the voltage channels of the equipment, on the screen we will see the oscillating alternating signal, if it is fixed we can make the reading, if it is moving the time base and the trigger must be adjusted to stop it.
In the oscilloscope we can read the period of the signal, this is the time it takes for the signal to repeat itself with this value, we can calculate the frequency with the formula, for the reading of the period the distance is measured on the labeled screen and multiplied by the time base
T = reading (cm) time base (s / cm)
f = 1 / T
Water rockets are very different from fuel powered rockets for many reasons. Explain some of the differences between them and why rockets that are launched into space require more power and thrust that water rockets?
Answer:
How is a water rocket different than a compressed air rocket?
Usually the rocket is made from a 2-liter soda pop bottle. Before launch, the bottle is filled with some amount of water, which acts as the "propellant" for the launch. Since water is about 100 times heavier than air, the expelled water produces more thrust than compressed air alone.
