Which of the following is the best evidence that work has been done on or by an object?

Answers

The answer is A.The energy of the object has changed.

The change in the energy of an object is the best evidence that work has been done on or by an object. Thus, the correct option is A.

What is Work done?

Work is done on an object or by an object whenever a force is applied on the object that moves it over a certain distance or change the energy of the object. This movement is a result of energy change.

We can calculate the energy transferred to an object, or the work done, by simply using the formula where we multiply the force by the distance moved in the direction of the force applied.

Therefore, Energy transferred = work done = force × distance moved in the direction of the force.

W = f × d

Therefore, the correct option is A.

Hello!

A likely hypothesis to the question "Do fertilizers make plants grow faster?" is: If we fertilize a plant, then its height increases faster. 

A hypothesis is a supposition made from data that is the basis for an investigation. The hypothesis formulates the central question of the investigation in an affirmative way. In this case, the affirmation that is the most similar to the question is If we fertilize a plant, then its height increases faster.

Also, a hypothesis should be written in a way that it can be proved through an experiment. In this case, an experiment can be designed from the hypothesis, measuring the height of the plants when adding fertilizer and when not, to test the hypothesis. This is called falsifiability.

Which of the following explains how heat flow within Earth changes its surface?

Molten material moves in one direction, moving the plates in the opposite direction
Molten material moves in one direction, moving the plates in the same direction
Cyclical movement of molten material moves plates in different directions
Cyclical movement of molten material moves all plates in one direction

Answers

The appropriate answer is C. Cyclical movement of molten material moves the plates in different directions. The cyclical movement refers to convection current in the mantle that are driven by heat from the earth's core. The heat from the core heats the the layer of the mantle closest to it. This layer is now less dense than its surroundings which forces it to rise. Once this rising plume reaches the base of the crust it cools and now becomes more dense than surrounding layers so it sinks. 

These continuous convection currents cause the crustal plates to converge, diverge or slide past each other in opposite directions.

Answers

From the outside is it’s shell, and on the inside is the nucleus (on the middle) which is made or protons (positive charge) and neutrons (neutral charge which is negate and positive) and Lastly there are electrons (negative charge) that orbit the nucleus like planets orbiting the Sun. The shell gets made as the electrons orbit the nucleus.
How do atoms differ from eachother?- their atoms might have different elections, neutrons, and/ or protons inside of it. Plus the location of the elections might be different too.

Answer:

This is the answer bro

Explanation:

Normally, the number of electrons is equal to the number of protons, which makes atoms electrically neutral. The number of protons in an atom is the defining feature of an atom. It's what makes one element different from another. The number of protons in an atom is called its atomic number.

The power of imagination helps a scientist to propose valid scientific explanations about the solar system use biased methods to answer questions about the solar system pose questions about the solar system which are not reasonable create theories about the solar system which are not acceptable

Answers

The first option is the correct answer - The power of imagination helps a scientist to propose valid scientific explanations about the solar system. As the option implies, what the scientist gets by imagination is simply a proposition (scientifically called an hypothesis), since there is limited evidence. The scientist's imaginations, and the propositions thereof, is the starting point for further investigation that yields valid scientific theories.

The power of imagination is integral to proposing scientific theories, particularly in the study of the solar system; however, these theories must be tested against experimental data to be accepted. Kepler's imaginative approach led to the formulation of laws that underpin our understanding of planetary motion, highlighting the scientific method's reliance on creativity tempered by empirical validation.

The power of imagination plays a crucial role in the scientific method, especially when it comes to understanding the solar system. Scientists use their creativity to construct theoretical models of how the universe could function and then perform experiments to see which models hold. For example, the work of Johann Kepler, who proposed the laws of planetary motion, showcases how imaginative concepts can lead to significant scientific advancements. While Kepler's models were initially based on mystical ideas, they eventually contributed to our modern understanding of celestial dynamics. Thus, the imaginative component of science allows for the proposal of new and sometimes revolutionary theories, but ultimately, it's through experimentation and data that these theories are validated or refuted.

Science thrives on new ideas and is always ready to assess the validity of different models and theories through careful experimentation. As new data come to light, scientists continuously refine their theories to reflect the most accurate understanding of the natural world. This process illustrates the dynamic and adaptive nature of scientific inquiry, which values empirical evidence overall.

A ski lift carries people along a 220-meter cable up the side of a mountain. Riders are lifted a total of 110 meters in elevation. What is the idea mechanical advantage of the ski lift?

Answers

Final answer:

The Ideal Mechanical Advantage (IMA) of the ski lift is 2. It is calculated by dividing the total length of the lift cable by the total change in elevation.

Explanation:

The question is asking about the Ideal Mechanical Advantage (IMA) of a ski lift. The IMA is determined by the ratio of the distance over which the input force is applied to the distance over which the output force is applied.

In the case of a ski lift, the input force is applied over the entire length of the cable, while the output force is applied over the change in elevation. Therefore, the IMA of the ski lift would be the total length of the cable (220 meters) divided by the total change in elevation (110 meters), giving an IMA of 2.

A spaceship orbiting earth flies to the moon. How is the gravitational force pulling on the spaceship related to the distance that the spaceship is from the earth? As the distance from the earth decreases, the gravitational pull on the spaceship would decrease. The gravitational pull of the earth is constant and therefore the gravitational pull on would not change. There is no gravity on the moon and therefore only the earth will exert gravitational force on the spaceship. As the distance from the earth increases, the gravitational pull on the spaceship would decrease.

Answers

The correct answer is "As the distance from the earth increases, the gravitational pull on the spaceship would decrease."

In fact, the gravitational force (attractive) exerted by the Earth on the spaceship is given by
[tex]F=G \frac{Mm}{d^2} [/tex]
where G is the gravitational constant, M the Earth's mass, m the mass of the spaceship and d the distance of the spaceship from the Earth. As we can see from the formula, as the distance d between the spaceship and the Earth increases, the gravitational force F decreases, so answer D) is the correct one.

A) move fast enough that the attraction between particles is overcome completely

B) Lose enough energy that the movement completely stops

C) Move slowly enough that strong attractions form, pulling the particles together

D) Are only able to slip and slide past each other

Answers

the answer is a, move fast enough that the attraction is overcome

Answer: Option (A) is the correct answer.

Explanation:

Sublimation is a process in which molecules of a solid substance are converted directly into gaseous phase without undergoing liquid phase.

This is because solid particles absorb the heat from their surroundings due to which bond between the molecules are broken down. As a result, molecules gain kinetic energy and they move rapidly into the atmosphere.

Thus, we can conclude that in the given situation the particles move fast enough that the attraction between particles is overcome completely.

Hey!

Formula for calculating work = Force × distance
Work done = Force applied on the object × distance travelled by it.

Hope it helps...!!!

The formula for calculating work is force multiplied by distance; that is the second option, as work is a measure of the energy transferred to or from an object and is calculated by multiplying the force with distance.

What is the work done by an object?

Work is a physical concept that describes the energy transferred when a force is applied to an object and is caused to move a certain distance and work is said to be done which can be positive, negative, or zero, depending on the direction and magnitude of the force. The formula expresses the fact that the amount of work done on an object depends on both the magnitude of the force applied and the distance, and is written as W = F x d.

Hence, the formula for calculating work is force multiplied by distance; that is the second option.
