The four parameters utilized to define the system are volume, pressure, temperature, and the number of molecules.

When temperature is constant, the product of pressure and volume is also constant. The Boyle's law or Mariotte's law refers to this relationship. An isothermal process is one that maintains a constant temperature.

Volume, Pressure, Temperature, and Number of Molecules are the four parameters used to define the system.

Answer:

I finish that module I'm sure it's D

Answer:

x = 265.5 m

Explanation:

To find the distance traveled by the car you first use the following formula:

\(v=v_o+at\)   (1)

vo: initial velocity = 65.0m/s

a: acceleration = 15.0m/s^2

t: time = 3.00 s

you replace the values of vo, t and a in the equation (1) in order to calculate the final velocity v:

\(v=65.0m/s+15.0m/s^2(3.00s)\) = 110 m/s

Next, you use the following formula:

\(v^2=v_o^2+2ax\)

x: distance traveled

You do x the subject of the formula and replace the values of vo, v and a:

\(x=\frac{v^2-v_o^2}{2a}\\\\x=\frac{(110m/s)^2-(65.0m/s)^2}{2(15.0m/s^2)}=262.5\ m\)

hence, the distance traveled by the car is 265.5 m

Answer:

Vf = 31 m/s

Explanation:

Have to use the Final Velocity Formula - Vf = Vi + a * t

Vf = Final Velocity

Vi = Initial Velocity

a = acceleration

t = time

* = multiply

Vf = 25 + 1.5 * 4

Vf = 25 + 6

Vf = 31 m/s

The final velocity of the car is 31 m/s.

The response D is correct as hot water has more energy than cold water, causing the molecules to move faster, leading to faster dissolution.

Hot water dissolves substances faster than cold water due to its higher energy level. The heat energy causes the water molecules to move faster, which increases the kinetic energy of the particles in the substance being dissolved. This therefore raises the probability of particle collisions, which accelerates the rate of disintegration.

Additionally, the stronger intermolecular forces between the water molecules make it easier for the solute particles to dissolve due to their increased energy level. This is why substances dissolution occurs faster in hot water than cold water.

Here, the newly produced atom will have a four-less atomic mass number and a two-less atomic number. A helium nucleus is another name for the alpha particle that was released. The alpha particles have a positive charge and a sizeable mass.

Ernest Rutherford investigated how radiation is deflected through a magnetic field to distinguish alpha decay from other types of radiation. Given that the particles carry a +2e charge, the alpha decay would deflect a positive charge.

Even for sensors positioned at significant track offsets, the computation method integrates three different speed calculation techniques to produce estimates for arbitrary train speeds.

A) I_t = I_i, C) 0.33 m, A) 0.53 times 10^-2 s

For the first question:

The correct expression for the transmitted intensity of an unpolarized beam of light passing through a polarizer is:

A) I_t = I_i

When an unpolarized light beam passes through a polarizer, the transmitted intensity is equal to the incident intensity. This means that the intensity of the light remains unchanged after passing through the polarizer.

For the second question:

The associated wavelength of a cell phone signal operating at 900 MHz can be calculated using the formula: wavelength = speed of light / frequency.

The speed of light is approximately 3.0 x 10^8 m/s.

Calculating the wavelength:

wavelength = (3.0 x 10^8 m/s) / (900 x 10^6 Hz)

wavelength = 3.33 x 10^-1 m

Therefore, the correct answer is:

C) 0.33 m

The wavelength of the cell phone signal is 0.33 meters.

For the third question:

To calculate the time it takes for a light signal to travel from one planet to another, we need to divide the distance between the two planets by the speed of light.

Calculating the time:

time = distance / speed of light

time = (1.6 x 10^6 m) / (3.0 x 10^8 m/s)

time = 5.33 x 10^-3 s

Therefore, the correct answer is:

A) 0.53 times 10^-2 s

The time for the light signal to travel from one planet to the other is 0.53 times 10^-2 seconds.

The true statement according to Newton's laws of motion is; "there is no net force on the block during the 2nd second as zero net force keeps the motion constant."

According to the Newton first law of motion, an object will continue in its state of rest or uniform motion unless it is acted upon by a net force. The action of a net force leads to an acceleration.

In the 2nd second of the journey, there is no net force on the block hence the block continues to move at constant velocity.

Explanation:

Gravity, the attractive force between all masses, is what keeps the planets in orbit. Newton’s universal law of gravitation relates the gravitational force to mass and distance

The force of gravity is what gives us our sense of weight. Unlike mass, which is constant, weight can vary depending on the force of gravity (or acceleration) you feel. When Kepler’s laws are reexamined in the light of Newton’s gravitational law, it becomes clear that the masses of both objects are important for the third law, which becomes a3 = (M1+ M2) × P2. Mutual gravitational effects permit us to calculate the masses of astronomical objects, from comets to galaxies.

The speed of the coaster at position B is 12mvB2. The value of the coaster speed at point B 3.016 m.

Speed is the rate in which something is traveling.

The speed of the coaster at position B can be determined using the work-energy theorem. According to the theorem, the work done by the gravitational force is equal to the change in kinetic energy. Therefore, the kinetic energy of the roller coaster at point B is equal to the potential energy at point A.

The potential energy at point A is equal to mghA, where m is the mass of the roller coaster, g is the acceleration due to gravity, and hA is the height of point A. Similarly, the kinetic energy at point B is equal to 12mvB2, where vB is the speed of the roller coaster at point B.

Therefore, the speed of the roller coaster at point B can be calculated as follows:

vB = √(2ghA/m) = √(2*9.8*30/m) = 5.48 m/s.

b) The efficiency of the roller coaster is 55%, so the actual speed of the roller coaster at point B would be 55% of the calculated speed. Therefore, the actual speed of the roller coaster at point B would be 5.48 * 0.55 = 3.016 m

Charge on a PVC pipe, q₁ = -0.0000007 C

Charge on a positively charged sweater, q₂ = 0.0000009 C

Separation between charges, d = 6 cm = 0.06 m

We need to find the magnitude of the force between charges. The force between two charges is given by :

\(F=\dfrac{kq_1q_2}{r^2}\\\\F=\dfrac{9\times 10^9\times 0.0000007 \times 0.0000009 }{(0.06)^2}\\\\F=1.575\ N\)
