B= nimbus clouds

If a heat engine has a thermal efficiency of 25% and absorbs 800 J from a high- temperature reservoir each cycle then the work output of the heat engine is 200 J.

To solve this problem, we need to use the formula for thermal efficiency, which is defined as the ratio of the work output of a heat engine to the heat input from a high-temperature reservoir:
Thermal Efficiency = Work Output / Heat Input
We are given that the thermal efficiency of the heat engine is 25%, or 0.25 in decimal form. We are also given that the engine absorbs 800 J from a high-temperature reservoir each cycle.
Using the formula for thermal efficiency, we can solve for the work output of the engine:
0.25 = Work Output / 800 J
Multiplying both sides by 800 J, we get:
Work Output = 0.25 x 800 J
Work Output = 200 J
Therefore, the work output of the heat engine is 200 J.
This means that out of the 800 J of heat input from the high-temperature reservoir, only 200 J is converted into useful work. The rest of the energy is lost as waste heat. This low thermal efficiency is due to the limitations of the heat engine's design and the laws of thermodynamics.

The density, dry density, void ratio, water content, porosity, and degree of saturation are 1.81 g/cm^3, 1.37 g/cm^3, 0.32, 0.31, 0.43, 1.00 and for b part 1.81 g/cm^3,  1.32 g/cm^3, 0.37, 0.37,  0.49 and 1.00 respectively.

To find the density, dry density, void ratio, water content, porosity, and degree of saturation for part (a) and (b), use the following formulas:

Density (part a) = Mass (89.3 g)/Volume (49.3 cm^3) = 1.81 g/cm^3

Dry Density (part a) = Mass of Soil Solids (67.9 g)/Volume (49.3 cm^3) = 1.37 g/cm^3

Void Ratio (part a) = Volume of Voids (21.4 g)/Volume of Soil Solids (67.9 g) = 0.32

Water Content (part a) = Mass of Water (21.4 g)/Mass of Soil Solids (67.9 g) = 0.31

Porosity (part a) = Volume of Voids (21.4 g)/Total Volume (49.3 cm^3) = 0.43

Degree of Saturation (part a) = Volume of Water (21.4 g)/Volume of Voids (21.4 g) = 1.00

For part (b):

Density = Mass (1.81 g)/Volume (1.00 cm^3) = 1.81 g/cm^3

Dry Density = Mass of Soil Solids (1.32 g)/Volume (1.00 cm^3) = 1.32 g/cm^3

Void Ratio = Volume of Voids (0.49 g)/Volume of Soil Solids (1.32 g) = 0.37

Water Content = Mass of Water (0.49 g)/Mass of Soil Solids (1.32 g) = 0.37

Porosity = Volume of Voids (0.49 g)/Total Volume (1.00 cm^3) = 0.49

Degree of Saturation = Volume of Water (0.49 g)/Volume of Voids (0.49 g) = 1.00

Answer: Different types of fuels have varying compositions and release different amounts of pollutants when burned. Here are some common types of fuels and the pollutants associated with them:

Fossil Fuels:

a. Coal: When burned, coal releases pollutants such as carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM).

b. Petroleum (Oil): Burning petroleum-based fuels like gasoline and diesel produces CO2, SO2, NOx, volatile organic compounds (VOCs), and PM.

Natural Gas:

Natural gas, which primarily consists of methane (CH4), is considered a cleaner-burning fuel compared to coal and oil. It releases lower amounts of CO2, SO2, NOx, VOCs, and PM.

Biofuels:

Biofuels are derived from renewable sources such as plants and agricultural waste. Their environmental impact depends on the specific type of biofuel. For example:

a. Ethanol: Produced from crops like corn or sugarcane, burning ethanol emits CO2 but generally releases fewer pollutants than fossil fuels.

b. Biodiesel: Made from vegetable oils or animal fats, biodiesel produces lower levels of CO2, SO2, and PM compared to petroleum-based diesel.

Renewable Energy Sources:

Renewable energy sources like solar, wind, and hydropower do not produce pollutants during electricity generation. However, the manufacturing, installation, and maintenance of renewable energy infrastructure can have environmental impacts.

It's important to note that the environmental impact of a fuel also depends on factors such as combustion technology, fuel efficiency, and emission control measures. Additionally, advancements in clean technologies and the use of emission controls can help mitigate the environmental impact of burning fuels.

Main answer:Edwin Hubble, an astronomer determined the important relationship between two variables that showed the universe is expanding. These two variables were the recessional velocity of galaxies and their distances. Explanation:Edwin Hubble was the first astronomer to show that the universe is expanding.

He determined an important relationship between two variables that showed the universe is expanding. These two variables were the recessional velocity of galaxies and their distances. He used a telescope to observe the spectra of light from galaxies and discovered that almost all galaxies' light was shifted to the red end of the spectrum. This shift in color is known as the redshift. It means that the light is moving away from us.

Hubble's observations showed that galaxies are moving away from each other. The galaxies farther away are moving faster than the galaxies that are closer. This means that the universe is expanding, and it's getting bigger. The relationship between the distance of galaxies and their recessional velocity is known as Hubble's Law.

Explanation:

Hope this helped.

Answer:

See the explanation below.

Explanation:

To solve this problem we must apply Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration and this force can be calculated by means of the following equation.

F = m*a

where:

F = force [N] (units of Newtons)

m = mass [kg]

a = acceleration [m/s²]

The mass of the tennis ball will always be the same therefore it will never change.

Now clearing a:

\(a=\frac{F}{m}\)

If the mass of the ball remains the same:

\(a = \frac{100}{m} ; a = \frac{200}{m};a =\frac{300}{m}\)

We see that for a force of 300 [N], the acceleration exerted on the ball must be greater. Therefore with the force of 300 [N] the greatest acceleration is achieved.

a)  x and y coordinates of the puck are x = 0, y = vt. c)  Hence, 8 is the only inertial frame of reference since in this frame the puck moves with a constant speed and along a straight line. b) The puck's path, as seen from 8″, is a parabola. are the answers

a) The hallmark of an inertial reference frame is that any object which is subject to zero net force will travel in a straight line at constant speed.

To illustrate this, consider the following: I am standing on a level floor at the origin of an inertial frame 8 and kick a frictionless puck due north across the floor.

The x and y coordinates of the puck as functions of time as seen from my inertial frame are as follows:

x = 0, y = vt

where v is the velocity of the puck.

b) Now, consider two more observers; the first at rest in a frame 8′ that travels with constant velocity v due east relative to 8, the second at rest in a frame 8″ that travels with constant acceleration due east relative to S.

(All three frames coincide at the moment when I kick the puck, and 8″ is at rest relative to 8 at that same moment.)

The coordinates x′ and y′ of the puck, as seen from 8′, are x′ = vt and y′ = vtt.

The puck's path, as seen from 8′, is a straight line parallel to the x-axis with slope v/v.

This straight line passes through the point (0,0) at time t=0.For 8″, the coordinates of the puck are given by x″ = vt and y″ = vtt + 1/2 at2.

The puck's path, as seen from 8″, is a parabola.

c)  It will have a vertex at (0,0), and it will be symmetric about the y-axis.

The slope of the puck's path at any point will be v + at.

Hence, 8 is the only inertial frame of reference since in this frame the puck moves with a constant speed and along a straight line.

The car's speed at the finish line of the race is approximately 81 m/s.

To calculate the car's speed at the finish line, we need to use the equations of motion. Since the car starts from rest and accelerates at a constant rate, we can use the equation:

v^2 = u^2 + 2as

where v is the final velocity, u is the initial velocity (which is 0 in this case), a is the acceleration, and s is the distance covered.

Given that the distance covered is 402 m and the car accelerates at a constant rate, we can rearrange the equation to solve for v:

v^2 = 0 + 2a(402 m)

v^2 = 804a m^2

v = sqrt(804a) m/s

Since the acceleration is constant throughout the race, we can directly substitute the value of a into the equation to find v. In this case, the value of a will result in v ≈ 81 m/s.

Therefore, the car is going at approximately 81 m/s at the finish line.

Its average speed will be 25 m/s approximately. The correct answer is option C

Average speed is the ratio of total distance travelled to the total time taken. It is a scalar quantity and the S.I unit is m/s

Given that a car travels one third of a path with speed of 50 m/s and two third of path with 20m/s.

If the car travels one third of a path with speed of 50 m/s, then the time taken will be

Speed = distance / time

Time = distance / speed

Time = 1/3 ÷ 50

Time = 6.67 x \(10^{-3}\) s

If the car travels the remaining two third of a path with speed of 20 m/s, then, the time taken will be

Time = distance / speed

Time = 2/3 ÷ 20

Time = 0.0333

Total time = 0.03333 + 0.00667

Total time = 0.04

The total distance travelled = 1

Average speed = Total distance travelled ÷ Total time
