A star will ultimately become a black hole when it collapses due to end of fuel.

When a star burns through the last of its fuel, the object may collapse, or fall into itself. For smaller stars which are about three times the sun's mass, the new core will become a white dwarf but when a larger star collapses, it turns into a black hole.

So we can can conclude that a star will ultimately become a black hole when it collapses due to end of fuel.

Kieran had a greater average speed than Jevon. Let us go into more detail in the explanation below. To compare the average speeds of Kieran and Jevon, we need to find out the speed of each person.

We can use the formula speed = distance/time. Kieran ran 8 laps in 18 minutes, which means he ran 8/18 = 0.44 laps per minute. To find out Kieran's speed, we need to multiply this by the length of one lap. If we assume that the length of one lap is 400 meters, then Kieran's speed is:0.44 laps per minute × 400 meters per lap = 176 meters per minute Jevon ran 6 laps of the track, but we don't know how long it took him.

Therefore, we can't calculate his speed directly. However, we can still compare his speed to Kieran's by using ratios. If we assume that Jevon ran the same length of track as Kieran, then we can write the following equation: Kieran's speed/Jevon's speed = Jevon's time/Kieran's time.

Answer:

5.00 × 10^14 Hz

Explanation:

The wavelength of the light in the medium can be calculated by using the formula:

λ = v / f

Where;

λ = wavelength (m)

v = speed of light

f = frequency (Hz)

From the provided information, λ = 600 nm (600 × 10^-9m), v = 3 × 10^8m/s.

λ = v / f

λ = 3 × 10^8/600 × 10^-9

λ = 0.005 × 10^(8+9)

λ = 0.005 × 10^17

λ = 5.00 × 10^14 Hz

The frequency of the light in the medium is 5.00 × 10^14 Hz

Work is an energy that move from or to one object into another object that might make the object have the displacement, or we can say work is equal to force multiply with displacement in meters. In formula form, it will be written as W = F x s. As per data given F = 36.8 N and s = 668 m. The work will be:

W = F x s

W = 36.8 x 668

W =  24,582J

C. D(S(r)) represents the distance of Robert's jump as a function of the height of the ramp.

Distance is a scalar quantity that represents the magnitude of the separation between two points in space. Distance can be measured in a variety of units, including meters, kilometers, miles, and others. It can be calculated in one, two, or three dimensions, depending on the situation. Distance is a fundamental concept in physics and mathematics, used to describe the position and motion of objects in space.

In physics, distance is used to calculate things such as velocity, acceleration, and force. It is also used to describe the position of objects in time and space, and to model the behavior of objects in motion. For example, when an object is thrown or launched into the air, the distance it travels can be calculated by considering factors such as initial velocity, air resistance, and gravity.

That the force opposes the car's motion, and the magnitude of the work is 8.05 × 10³ J, rounded to three significant figures.

To calculate the work done by the force, we use the formula: Work = Force × Distance × cos(θ), where θ is the angle between the force vector and the displacement vector. In this case, the force vector F is given as\(\vec{F} = (-68.0 , \text{N}) \hat{\imath} + (36.0 , \text{N}) \hat{\jmath}\), and the car travels a distance of 44.0 m in a direction 240.0° counterclockwise from the +x-axis. The angle between the force vector and the displacement vector is equal to the angle between the +x-axis and the displacement vector.

Substituting the given values into the formula, we have: Work = (-68.0 N) × 44.0 m × cos(240.0°). Calculating the cosine of 240.0° gives us -0.5. Plugging this value into the formula, we find that the work is -8.05 × 10³ J. This negative value indicates that the force acts in the opposite direction of the displacement, opposing the car's motion. Therefore, the work done by the force on the car is 8.05 × 10³ J.

According to Newton's second law of motion, acceleration is directly proportional to the net force applied to an object and inversely proportional to its mass. Therefore, in order to have the smallest acceleration, we would need to have the smallest net force applied to the object and/or the largest mass.

So, the set of conditions that would result in the smallest acceleration are:

Smallest net force: If the net force applied to an object is small, it will result in a smaller acceleration. For example, if a car is moving at a constant speed on a level road, the net force on the car is zero, and the acceleration is also zero.

Largest mass: If the object has a large mass, it will require a larger force to produce the same acceleration.

b. Float

Explanation:

If a body has specific gravity of less than 1, then it will float on water. To understand this we must understand relative density. That is the ratio of density of a substance to the density of reference material. We usually take water as reference material. Water has density 1g/cm³. It gravity is now less than 1 it will mean that It is less dense than water and hence float.

Answer:

\(\boxed {\boxed {\sf v\approx0.24 \ m/s}}\)

Explanation:

Velocity can be found by dividing the displacement by the time.

\(v=\frac{displacement}{time}\)

The displacement is 4.77 meters and the time is 19.5 seconds.

\(displacement=4.77 \ m \\time=19.5 \ s\)

Substitute the values into the formula.

\(v=\frac{4.77 \ m }{19.5 \ s}\)

Divide.

\(v=0.244615385 \ m/s\)

Let's round to the nearest hundredth (just to make the answer more concise).

The 4 in the thousandth place tells us to leave the 4 in the hundredth place.

The velocity of the turtle is about 0.24 meters per second.

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.

200N towards south are the magnitudes and direction of both the resultant force and equilibrant force.

Define force

A force is an effect that changes, or accelerates, the motion of a mass-containing object. It is a vector quantity since it can be a push or a pull and always has magnitude and direction.

The entire force operating on the item or body, combined with the body's direction, is referred to as the resultant force. When the object is stationary or moving at the same speed as the object, the resultant force is zero.

Between F1 and F2 , resultant force will be 100N towards 45.0degrees north of west,

When the elevator stops, its speed decreases from 4 m/s to 0 m/s.

This suggests a slowing down. The amount of force being applied to the

F= mass times acceleration

Assuming the deceleration is constant, we have the following equation:

V = U + at

Where V = Final speed = 0

U = initial speed = 4

a = acceleration

t = time

Solving, we get:

0 = 4 + 2a

a = -2 m/s^2

Solving, we get:

0 = 4 + 2a

a = -2 m/s^2

Thus the object decelerates at 2 m/s^2
