which of the following graphs will yield a straight line for an ideal gas? group of answer choices n versus v (p and t are constant) all of these graphs v versus t (n and p are constant) p versus 1/v (n and t are constant) t versus p (n and v are constant)
The graph that will yield a straight line for an ideal gas is "p versus 1/v (n and t are constant)".
This is known as the Boyle's law, which states that at constant temperature, the pressure and volume of a gas are inversely proportional.
When the pressure of a gas is increased, the volume decreases and vice versa, keeping the temperature constant. This relationship can be mathematically expressed as
pV = constant,
where p is pressure and
V is volume.
By rearranging this equation, we get p = constant/V.
Hence, the graph of p versus 1/V will yield a straight line with a negative slope, where the constant represents the product of pressure and volume.
This relationship is applicable to ideal gases, which are characterized by having negligible volume and intermolecular forces. In real gases, there may be deviations from this relationship due to the presence of intermolecular forces and volume.

B. move farther apart
Explanation:Note that:
• The higher the temperature of a substance, the higher the kinetic energy possessed by its molecules
,• The higher the kinetic energy possessed by the molecules, the higher their speed of motion
,• The molecules of a gas have higher kinetic energy, hence they collide with each other and with the wall of the container.
When water is heated from 25°C to a gas at 100°C, the molecules posses higher kinetic energy(due to increase in temperature). Therefore, they move farther apart.

MOMENTUMAccording to Newton's second law: The rate of change in momentum is directly proportional to the force applied. That is,
F = ma
Given that an archer uses an average force of 50.0 N to draw the string of his bow through a distance of 0.412 m. Then, he fires a 297 g arrow straight up into the air.
The parameters given are;
Force F = 50 NDistance S = 0.412 mMass M = 297g = 0.297The maximum speed of the arrow at the instant it leaves the bow can be calculated by first calculating the acceleration.
F = ma
Substitute all the necessary parameters
50 = 0.297a
a = 50 / 0.297
a = 168.4 m/\(s^{2}\)
by using third equation of motion
\(V^{2}\) = \(U^{2}\) + 2as
Since it is starting from rest, U = 0
\(V^{2}\) = 2 x 168.4 x 0.412
\(V^{2}\) = 138.72
V = \(\sqrt{138.72}\)
V = 11.8 m/s
The maximum height reached by the arrow in its flight into the air will be calculated by the same formula where acceleration a = g
\(V^{2}\) = \(U^{2}\) - 2gH
At maximum height, final velocity V = 0
0 = \(11.8^{2}\) - 2 x 9.8 H
138.7 = 19.6H
H = 138.7 / 19.6
H = 7.08 m

This voltage across the final seven resistors in our series configuration of 18 resistors is 3.5V.
What is resistor and its uses?A resistor is a passive electrical component with two terminals that controls or restricts the passage if current in electrical circuits. The main job of a resistor is to lower the voltage and lessen current flow in a specific area of the circuit.

a small truck has a mass of 2165 kg. how much work is required to decrease the speed of the vehicle from 21.0 m/s to 12.0 m/s on a level road?
The work required to decrease the speed of the small truck from 21.0 m/s to 12.0 m/s on a level road is approximately 319,717.5 kg * m^2/s^2.
To calculate the work required to decrease the speed of the small truck, you need to know the change in kinetic energy. The formula for calculating work is:
Work = Change in Kinetic Energy
The change in kinetic energy can be calculated using the formula:
Change in Kinetic Energy = (1/2) * mass * (final velocity^2 - initial velocity^2)
Given:
Mass of the small truck = 2165 kg
Initial velocity = 21.0 m/s
Final velocity = 12.0 m/s
Let's calculate the change in kinetic energy:
Change in Kinetic Energy = (1/2) * 2165 kg * ((12.0 m/s)^2 - (21.0 m/s)^2)
Simplifying the equation:
Change in Kinetic Energy = (1/2) * 2165 kg * (144 m^2/s^2 - 441 m^2/s^2)
Change in Kinetic Energy = (1/2) * 2165 kg * (-297 m^2/s^2)
Change in Kinetic Energy = -319,717.5 kg * m^2/s^2
The negative sign indicates that work is done to decrease the speed.
Therefore, the work required to decrease the speed of the small truck from 21.0 m/s to 12.0 m/s on a level road is approximately 319,717.5 kg * m^2/s^2.

Push or pull of an object is considered a force. Push and pull come from the objects interacting with one another. The push or pull on an object with mass causes it to change its velocity.Force is an external agent capable of changing a body’s state of rest or motion. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force, and the application of force is the point where force is applied.Newton’s 2nd law states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the object’s mass. i.e. F = MaThus Force is directly proportional to acceleration of an object.

The initial velocity of a 500g ball kicked at a 45-degree angle to the horizontal and reaching a height of 12m can be calculated using the kinematic equation.
What is the kinematic equation?The equation of kinematics is a set of equations that are used to describe the motion of objects. They relate to displacement, velocity, acceleration, and time. Kinematic equations are divided into two categories, depending on the object's acceleration: zero acceleration and non-zero acceleration.
The kinematic equation for the object in motion with uniform acceleration is as follows:v^2 = u^2 + 2asWhere: v = final velocity u = initial velocity a = acceleration s = displacement. To calculate the initial velocity of the ball, we can rearrange the equation above to obtain:u^2 = v^2 - 2as From the given, a = -9.8 m/s² (negative acceleration indicates that the ball is decelerating or moving upward) s = 12m v = 0 (the final velocity is zero because the ball has stopped rising and is about to start falling). We'll use these values to calculate the initial velocity of the ball.u² = (0)² - 2(-9.8)(12)u² = 235.2u = sqrt(235.2)u = 15.33 m/s.

(a) what is the spring's maximum compression if the track is frictionless? m (b) if the track is not frictionless, would the spring's maximum compression be greater than, less than, or equal to the value obtained in part (a)? greater
(a) The spring's maximum compression if the track is frictionless is 0.0364 m.
(b) If the track is not frictionless, the spring's maximum compression would be greater than the value obtained in part (a). Friction is caused by the forces of friction, which oppose the motion of the moving object.
Friction acts in the opposite direction to the direction of motion. The total energy of a system is conserved in the absence of non-conservative forces. The sum of kinetic energy (K) and potential energy (U) is equal to the total energy of the system (E). The spring's potential energy is given by (1/2)kx^2, where k is the spring's force constant and x is the spring's compression. The block's kinetic energy is given by (1/2)mv^2, where m is the block's mass and v is the block's velocity immediately before the collision.
Consider a horizontal track on which a 0.200-kg block is moving with a velocity of 1.20 m/s. There is a light spring located at the end of the track with a force constant of 5.15 N/m. If the track is frictionless, what is the maximum compression of the spring? m = 0.200 kgv = 1.20 m/sk = 5.15 N/m
The spring's maximum compression, x, can be calculated using the following formula: \((1/2)mv^2\) = \((1/2)kx^2x\) = \(\sqrt{sqrt(mv^2/k)x}\)
= \(\sqrt{((0.200 kg)(1.20 m/s)^2/(5.15 N/m)}x\) = 0.0364 m.
If the track is not frictionless, the spring's maximum compression would be greater than the value obtained in part (a). This is because friction does negative work on the block as it moves down the track, reducing the block's kinetic energy. As a result, the spring must do less work to bring the block to a stop, resulting in a greater maximum compression of the spring.

if a light wave hits a smooth surface at an angle of incidence of 40 degrees the angle of reflection is
According to the law of reflection, when a light wave hits a smooth surface, the angle of reflection is equal to the angle of incidence. Therefore, if the angle of incidence is 40 degrees, the angle of reflection will also be 40 degrees.
The law of reflection states that the angle of incidence (the angle between the incident light ray and the normal to the surface) is equal to the angle of reflection (the angle between the reflected light ray and the normal to the surface). This law holds true for smooth surfaces, such as mirrors or still water.
In this case, when a light wave hits a smooth surface at an angle of incidence of 40 degrees, the angle of reflection will also be 40 degrees. The incident light ray and the reflected light ray will be on opposite sides of the normal to the surface, forming an equal angle with it.
Understanding the law of reflection is crucial in various applications, including optics, image formation, and the study of light behavior. It allows us to predict and analyze the behavior of light rays when they encounter reflective surfaces, enabling us to understand how images are formed and how light interacts with different materials.
