Answer:

39,200J

Explanation:

just took the test

The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J

Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.

mass(m)  = 10kg

g (acceleration due to gravity) = 9.8m/s^2

altitude(height (h)) = 400m

Meteor's Potential energy = m * g * h

                                           = 10 * 9.8 * 400 = 39200 J

correct option will be a) 39200 J

Answer: Explanation:

Plants and animals each produce the gases that the other needs to live. Plants need carbon dioxide—people and other animals exhale carbon dioxide as a waste product. People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.

Answer:

There are many factors that can affect the speed of a car, including:

Engine size and power: A car with a larger and more powerful engine will be able to accelerate faster and reach higher speeds than a car with a smaller engine.

Transmission: Cars with manual transmissions typically have better acceleration than those with automatic transmissions because the driver can control the gears and timing of the shift.

Aerodynamics: Cars that are designed with aerodynamic shapes and features, such as a low profile or smooth body, will be able to reach higher speeds and maintain them more easily than cars with less aerodynamic designs.

Weight: Cars that are lighter in weight will be able to accelerate faster and reach higher speeds than cars that are heavier.

Tires: Cars with wider tires will typically have more grip and better traction, which can allow them to reach higher speeds and handle better.

Suspension: Cars with better suspension systems will be able to maintain stability at high speeds and handle better.

Driving technique: The way a driver handles a car can also affect its speed, a skilled driver can make the most of the car's performance and get a better outcome.

Answer:

distance and time

Explanation:

Speed depends upon distance and time. So, if the distance is long but time is less, the speed will be high. On the other hand, if the distance is short and time is enough, the speed of the car will be slow.

The idea that hard work is the most important aspect of new inventions existed before Edison gave his quote, however.

The idea behind this quote is that it is easy to have a good idea, or a creative insight. However, to follow through with that idea, and turn it into a reality, takes a level of patience and dedication that few people have.

2. The angle if refraction is always less than the angle of incidence as shown in the table. If you were to calculate the averages of all 3 test, it would still be smaller than the angle of incidence.

3. The angle of refraction is always less than the angle of incidence because the light ray must be moving from a optical density than air hence the light ray could seem bended. This is because the the speed of a wave is determined by the medium through it is passing. When light speeds up as it passes from one material to another, the angle of refraction tends to be larger than the angle of incidence. An example of this would be when light passes from water to air or glass to water. This change also makes the image look shifted to the side.

Answer: An ecosystem is a community of plants and animals and their physical surroundings

Explanation: An ecosystem is a geographic area where plants, animals, and other organisms as well as weather and landscape work together to form a bubble of life. Ecosystems contain biotic and abiotic factors both. Biotic factors include plants, animals, and other organism

Answer: An ecosystem is a community of plants and animals and their physical surroundings.

Explanation: Ecosystem plays an essential role for the existence of living organisms in the planet Earth. A balanced ecosystem is attained as a result of various reasons it includes the live ratio of diverse varieties of organisms in a particular ecosystem, necessary physical, biological, and chemical conditions that promotes the living of organisms, and the balanced atmosphere attained as the result of temperature, wind, and humidity.

As all the above mentioned properties are necessary for maintaining a sustainable ecosystem, it is clearly understood that an ecosystem is a community of plants and animals and their physical surroundings.

Answer:

2.72 m

Explanation:

Sound travels at a certain speed and has a frequency and wavelength. The relationship between the speed of sound (V), its frequency (f), and wavelength (λ) is the same as for all waves, it is given by the equation:

V = fλ

The speed of sound in air (V) is 334 m/s

Frequency of sound (f) = 123 Hz

Wavelength = λ

V = fλ

λ = V/f = 334/123

λ = 2.72 m

1/v + 1/u = 1/f

1/12 - 1/20 = 1/f

5-3/60 =1/f

2/60 = 1/f

 1/30 = 1/f

 f= 30

This was done by mirror formula

Answer:

Conduction is heat transfer through stationary matter by physical contact. (The matter is stationary on a macroscopic scale—we know that thermal motion of the atoms and molecules occurs at any temperature above absolute zero.) Heat transferred from the burner of a stove through the bottom of a pan to food in the pan is transferred by conduction.

Convection is the heat transfer by the macroscopic movement of a fluid. This type of transfer takes place in a forced-air furnace and in weather systems, for example.

Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of Earth by the Sun. A less obvious example is thermal radiation from the human body.     I hope this helps you

Answer:

, if we see we are considering this initial mass of this in this particular case, the initial mass of substantiated- or we can say, mercury oxide heated, it is, we can say, 27 grains. So this is the initial mass which is heated here. It is like this and what we can say we can consider this consent, passion of mass, so consummation of mass. We are looking here, the log, the conservation of the mass, so conservation of mass state at mass. It is always converted, but if it's not the case, we can also modify it it through mass and energy. They are combined converted or we can say, mass energy equivalence here so mass. It is confirmed in this case, so we can say, but here it is said that initially mass was 27 gram and finally mass was 25 gram. So but as we know, mass it is conserved mass, it is always conserved, so if the mass it is conserved, we should say this thing that the lost in the 2 gram weight must be due to the evaporation or we can say formation of the gases which Have been escaped, that is why it cannot be recorded, so we can say 2 gramos in the mass to the escape of the gas, or we can say evaporation. So.

Answer:10

Explanation:

In the context of the Moon model, the fraction of the Moon that was always lit up by the light is half, or 1/2.

The explanation for this is that the Moon model discussed previously most likely depicts the Moon's phases as seen from Earth. The phases of the moon are caused by distinct areas of the lit side of the moon that are visible from Earth at various times during its orbit.

The Sun always illuminates half of the Moon's surface, leaving the other side in darkness. From Earth, we can only see the bright portion; the unlit portion is invisible. Different phases result from variations in the visible fraction of the lighted half of the Moon as it revolves around the Earth.

Therefore,  the fraction of the Moon that was always lit up by the light is half, or 1/2.

Answer: (B) 4 Seconds

Explanation: The Balance of weight and air resistance equals out after 4 seconds giving you your terminal velocity. (the fastest speed you can travel at your given weight and air resistance)

Answer : B. The sjydriver has the fastest speed at 4second.

What is air resistances ?

--Air resistance is a type of friction force.

-- Air resistance, there are not two solid surfaces in contact.

-- Air resistance is the frictional force acting on an object and the air around them.

--This means that friction always pushes in the opposite direction than the skydiver is travelling, therefore slowing the skydiver down.

Concept Used

-- When the skydiver jumps off the plane, their speed would accelerate because the pull of gravity on the person, or their weight force, is greater than the air resistance slowing them down.

-- A person’s weight force will always stay the same.

-- The weight force of the person will equal their air resistance.

-- This would make the skydiver travel at constant speed.

--To travel at constant speed forces have to be equal to zero.

--This constant speed is called terminal velocity
