If a running system has a total change in the heat of 315 joules, and it is running at a temperature of 350 k, the entropy will be e. 0.762 joules/kelvin.

Entropy is essential for understanding the behavior of many physical systems, such as in thermodynamics, statistical mechanics, and thermochemistry.

Entropy can be used to analyze the efficiency of a system, as well as its stability and predictability.

This can be calculated by using the formula  S = ΔQ/T, where S is entropy, ΔQ is the total change in heat and T is temperature. In this case ΔQ = 315 Joules and T = 350K.

Plugging these values into the equation gives us S = 315/350, which equals 0.762 joules/kelvin. Hence, option e is correct.

When an item is projected vertically upward, its velocity is assumed to be zero at its highest point, yet it still experiences acceleration from the gravity of 9.8 m/s^2.

This means that anything that is drawn toward the center of the earth has a 9.8-meter acceleration per second as it "falls" to the earth. As a result, each second that such a body is dragged towards the earth, its velocity (the speed with direction) increases by around 9.8 meters per second.

The velocity is constant in uniform motion. In terms of time, neither its magnitude nor its direction change.

Distance is the length of any path connecting any two places. When measured along the shortest path between any two points, displacement is the direct distance between them. The direction is ignored when calculating distance. The direction is accounted for in the displacement calculation.

The required work applied to a 1000 kg car when it is pushed 1000 m up along a 10- degree incline at a constant velocity is calculated to be 4.6 × 10⁶ J.

Given that,

Mass m = 1000 kg

Displacement d = Δx = 1000 m

Angle of inclination θ = 10°

Coefficient of friction μ = 0.3

The equation for work done is known to be,

W = F × d

We must divide the force of gravity into its component parts and examine the side acting in the x-direction in order to calculate the force of gravity in that direction.

F gx direction = F g sinθ = mg sinθ

The force of friction is directly related to  μ times the normal force.  The normal force in this situation is equivalent to the y component of the force of gravity.

F gy direction = F g cosθ = mg cosθ

We know force of friction, Ff = μ FN

FN = F gy direction

Ff = μ mg cosθ

We know that our force applied must balance both of these forces,

F applied = mg sinθ + μ mg cosθ

As, W = F × d = (mg sinθ + μ mg cosθ) d = ( 1000× 9.8 sin10° + 0.3 × 1000× 9.8 cos10°) 1000 = (9800 sin10° + 2940 cos10°) 1000 = (0.17 × 9800 + 0.985 × 2940) 1000 = (1666 + 2895.9) 1000 = 4561.9 × 10³ J = 4.6 × 10⁶ J

The correct option is B, the sound that reaches the ears after bouncing off a wall or a floor is called indirect sound.

Indirect sound is a type of sound that is not heard directly by the listener. Instead, it is heard through reflections of the original sound off of nearby surfaces. This sound is more muffled, as the reflections tend to lose some of the original sound's energy as it is reflected from wall to wall. Indirect sound is often used in recording studios and concert halls, as it can create a more natural or realistic sounding environment.

This is due to the fact that in real life, the sound is rarely heard directly by the listener, but rather bounces off of nearby surfaces. By using indirect sound, a more natural sound can be created for the listener. Indirect sound is also used in sound reinforcement systems, as it can help distribute sound more evenly throughout a space. This can help to create a more uniform sound.

Explanation:

The change in length of the cord due to a stretching force of 0.5N is given by Hooke's law:

ΔL = k * ΔF

Where ΔL is the change in length, k is the spring constant and ΔF is the change in force.

Since the spring constant for the cord is 3N/cm, the change in length due to a stretching force of 0.5N is:

ΔL = (3N/cm) * (0.5N) = 1.5 cm

Since the cord is already 350cm long, the total length of the cord when the stretching force is 0.5N is 350cm + 1.5cm = 351.5cm.

To find the length of the cord when the stretching force is 2.5N, we can use the same formula:

ΔL = (3N/cm) * (2.5N) = 7.5 cm

The total length of the cord when the stretching force is 2.5N is therefore 351.5cm + 7.5cm = 359cm.

The volume of air in the room. The volume of the room is given by the product of its length, width, and height=  18.015 g/mol.

Volume of air = 5.0 m × 9.0 m × 2.4 m = 108 m^3

Next, we need to find the number of moles of water vapor present in the air at 85% of the vapor pressure of water at 30°C.

The vapor pressure for water at 30°C is 31.8 torr. At 85% of this value, the vapor pressure of water in the air is:

Vapor pressure in air = 0.85 x 31.8 torr = 27.03 torr

We can use the Ideal Gas Law, PV = nRT, to find the number of moles of water vapor present in the air.

P = 27.03 torr

V = 108 m^3

R = 8.314 J/mol·K (The universal gas constant)

T = 303 K (Temperature in kelvins)

n = (PV) / (RT)

mass of water = n * M(H2O)

It is to be noted that based on the information provided, it is not possible to calculate the distance of the planet from its sun as we need more information about orbit and its eccentricity.

The distance of your fictional planet from its sun, and its orbital period, can be calculated using the information you've provided about its day duration, orbit duration, year duration, and radius.

The distance between a planet and its sun is known as an astronomical unit (AU). To calculate the distance in AU, you can use the formula: d = (T² * G * M_sun) / (4 * pπ²)

where T is the planet's orbital period in Earth years, G is the gravitational constant (6.67 x 10^-⁻¹¹ m³ kg^⁻¹ s^⁻²), M_sun is the mass of the sun (2 x 10^30 kg), and pi is the mathematical constant (3.14).To find the orbital period you need to know year duration in seconds and divide it by 365.25 for Earth-based standard.

The distance traveled before the car comes to a stop is 66.66 m. It's important to note that the negative sign on acceleration indicates that the car is slowing down.

To find the distance traveled before the car comes to a stop, we can use the formula for distance traveled under constant acceleration. The formula is:

Distance = initial velocity * time + (1/2) * acceleration * time^2

The car is traveling at an initial velocity of 20 m/s and the acceleration is given by the function -6.0t, where t is the time in seconds.

We can find the time it takes for the car to come to a stop by setting the final velocity to 0 and solving for t.

0 = 20 + (-6.0)t

t = 20/6

t = 3.333 s

Now that we have the time, we can substitute it back into the distance formula along with the initial velocity and acceleration:

Distance = 20 * 3.333 + (1/2) * -6.0 * (3.333)^2

Distance = 66.66 m

The reaction distance for a vehicle traveling at 60 mph on the highway is 312 feet, and the reaction distance for a vehicle traveling at 80 mph is 496 feet. Simply put, at current speeds, doubling the car's speed will result in a three-fold increase in stopping distance.

According to Coulomb's Law, the magnitude of the electric force between two negative charges is given by:

F = k * q1 * q2 / r^2

where k is the Coulomb constant (8.99 x 10^9 N m^2/C^2), q1 and q2 are the charges, and r is the distance between them.

Plugging in the given values, we get:

2N = 8.99 x 10^9 N m^2/C^2 * (-3 x 10^-6 C)^2 / r^2

Solving for r, we get:

r = sqrt(8.99 x 10^9 N m^2/C^2 * (-3 x 10^-6 C)^2 / 2N)

r = 4.44 x 10^-3 m

Coulomb's Law states that the magnitude of the electric force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them. The constant of proportionality is known as the Coulomb constant (k).
