Answer:
4 meters
Explanation:
The formula for gravitational potential energy is mgh, where m is the mass of the object in kilograms, g is the gravity, and h is the height in meters. You can use this to set up the following equation:
400=100 * h
h=4 meters
Hope this helps!
The gravitational potential energy is 400J of the box whose weight is 100N. Therefore, the height for which box is above the ground is 4 meters.
What is Gravitational Potential energy?
Gravitational potential energy is the energy which an object possesses because of its position above the ground level in a gravitational field such as the gravitational field of the Earth. The gravitational acceleration of the Earth can be assumed to be constant at about 9.8 m/s².
The gravitational potential energy can be calculated by the formula:
G.P.E = m × g × h
where, G.P.E = Gravitational Potential Energy,
m = mass of an object,
g = acceleration due to gravity = 9.8 m/s²,
h = height which the box attains
G.P.E = w × h (Since, w = m × g)
h = G.P.E. / w
h = 400J / 100N
h = 4 meters
Therefore, the height of the object is 4 meters.

What’s the biggest change to San Joaquin Valley ecosystems caused by humans in the past 150 years?
Answer:
the biggest change to San Joaquin Valley ecosystems caused by humans in the past 150 years is the shortage of water in the river.
Explanation:
During 150 years, the San Joaquin Valley ecosystems was extremely damaged by the human activities such as building of dams and diversion of river. The San Joaquin Valley has a productive agriculture land due to availability of water. Due to building of dams, the amount of water in the river is decreases and also the population of many fish species decreases. this is because of the disturbance occurs in their natural habitat due to human activities.

Complexity is a measure of how difficult it is to understand something. What is an example of complexity in the natural world?
Answer:
Answer:
Multicellular organism is the example of complexity of the natural world.
Explanation:
Multicellular organism such as human which is made of billions of cell. Each cell perform a specific function. The function of one organ is different from the other organ. For example, brain of human is made of millions of neurons which takes instructions from brain to the organs and bring messages from organs to the nervous system in the form of electrical impulses. In short every system in our body is full of complexity.
What is a “shared derived character”?
Answer:
A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals.
Answer:
A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals. Shared derived characters can be used to group organisms into clades. For example, amphibians, turtles, lizards, snakes, crocodiles, birds and mammals all have, or historically had, four limbs. If you look at a modern snake you might not see obvious limbs, but fossils show that ancient snakes did have limbs, and some modern snakes actually do retain rudimentary limbs. Four limbs is a shared derived character inherited from a common ancestor that helps set apart this particular clade of vertebrates.

Leaf cells have more chloroplasts than cells in other parts of the plant
Answer:
Chloroplasts are organelles that conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in plant and algal cells. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, much amino acid synthesis, and the immune response in plants. The number of chloroplasts per cell varies from one, in unicellular algae, up to 100 in plants like Arabidopsis and wheat.

Why do we need human dna
DNA. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things.
All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.
We need human DNA since it give us the long term info storage, which is needed
DNA contains instructions for development, survival, and reproduction. DNA sequences must be translated into signals to make proteins, which do most of our body's job.
What is human genome?DNA stores the instructions that are necessary for an organism to grow, maintain its existence, and reproduce itself. In order for these duties to be carried out, the sequences of DNA need to be transformed into messages that can be utilized in the production of proteins. Proteins are the complex molecules that are responsible for the majority of the work that is done in our bodies.
The human genome is comprised of all of the nucleic acid sequences that are found in humans. These sequences are stored as DNA within the 23 chromosome pairs that are found in the nucleus of cells, as well as in a tiny DNA molecule that is located within the mitochondria of each individual cell. In most cases, these are considered to be two distinct components: the nuclear genome and the mitochondrial genome.

Your teacher places the following supplies on a table: water, hot plate, salt, beakers, food coloring, and test tubes. Using the supplies listed, how could you plan an investigation of how differences in temperature and salinity affect ocean currents? Include the following vocabulary in your explanation: salinity, density, temperature, wind, surface currents, deep currents. Make sure to include specific details and steps.
Answer:
Higher saline water is more dense that lower saline water
Explanation:
The ocean salinity varies with rainfall, run off from estuaries and the pattern of ocean current. In addition to this, higher temperature affects the kinetic movement of water as well as the salinity. The movement of the wind also contributes to the movement of water and the particles and solute distribution. The surface currents do not do much to mix the entire body of water and this is because this is from less dense areas. Deep currents factor in to mix just the heavier more dense layers.
In planning an experiment to test this one would do two experiments.
First: Heat 4 batches of water at different temperatures and color the different temperatures with different food coloring. Next layer the water carefully from hottest to coldest in a beaker and then from coldest to hottest in another beaker.
Second: Dissolve salt in 4 batches of water increasing the amount by half each time. Color each with different food colouring and layer the salty water from least salt to most salt in a beaker. Layer the water from most salt to least salt in another beaker.
Make observations:
The cooler water should be more dense and sink to the bottom while the saltier water should be more dense and sink to the bottom.

Is someone walking up to you from behind? A friend is walking up to you from behind. What three observations would help you predict when they would reach you?
Answer:
Three things i will observe are :
The sound of their movement when approaching meThe frequency of their foot stepThe distance they are away from meExplanation:
In my opinion, the three points highlighted above can go a long way to help predict how soon or when they would reach meThe sound of their foot steps will determine how far or close they are from from me, if the sound is loud they are closest, if it is low then they are at a distance father.The frequency of their foot steps tell me about the speed with which they are approaching me, if the frequency is high, then they will approach sooner and vice versaThe distance they are way from me can help estimate when they would reach me, though still dependent on items one and two above.
