What Do You Notice About The Density Of The Floating Objects
Answers
Answer:
the object should have 1g/cc or 1gram per cubic centimeter should be it's density to float
Answer:
To predict if the object will float or sink in water, compare the mass to the volume. If themass is larger, the object will sink.If the density is greater than 1g/cm3, the object will sink. If the density is less than 1 g/cm3, the object will float.

Summarize the Natural Processes of weathering ,erosion, and deposition
Answers
Answer:
I won’t do it in paragraph form cuz it will look very choppy but here you go:
Weathering is when the weather itself changes something, like when a metal bike gets rusty after sitting outside for a long time, or when a plant grows out of concrete.
Erosion is when something gets eroded away at. Like when something has water or wind is flowing against it so much that it changes shape. This is how canyons are made.
Deposition is when a gas turns into a solid, removing energy and skipping the liquid step (frost forming on car window)
Erosion : In earth science, erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location (not to be confused with weathering which involves no movement).
Deposition : Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.

Option C
Explanation:
Answer:
Option C
Explanation:
When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s
kinetic energy is given as

The process of cellular respiration occurs in plant and animal cells and involves chemical reactions with oxygen to release stored energy. Therefore, option (D) is correct.
What is cellular respiration?Cellular respiration can be defined as a set of metabolic reactions taking place inside the cells to change biochemical energy obtained from the food into a chemical compound known as adenosine triphosphate (ATP).
Metabolism can be described as a set of chemical reactions carried out to manage the living state of the cells in an organism. These can be divided into two classes: Catabolism is the process of breaking molecules to get energy. Anabolism is the process of synthesizing all compounds needed by the cells.
Cellular respiration takes place in both plants and animals but the method of obtaining energy from cellular respiration is different in plants and animals.
Cellular respiration involves the breakdown of glucose in both plants and animals which provides energy.

HELP! 100 POINTS! A cinder block is pulled 0.50 meters to the right in 3 seconds. What is the block's average speed to the nearest hundredth of a meter per second (m/s)?
Answers
The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
Explain why the change you made caused the stingwing population to decrease. Use energy storage molecules to explain your answer.
Answers
Answer:
Reprduce
Explanation:
The decrease in the stingwing population was caused by the change in energy storage molecules. Stingwings rely on energy storage molecules, such as glycogen and fats, to fuel their activities and survival. If the change disrupted their ability to store and utilize these molecules, their energy levels would decrease, leading to decreased population size.

Hey,
So what you would do here is first choose a biome, such as the desert for example, then choose an organism that lives there, or an animal. Then think of what it is like where it lives, is it dry, cold, windy, and so force, just describing the place by its looks and climate. How would this population increase, maybe it would be if there was suddenly more food there for them, or if their ecosystem got better for them to live, then, if they populated more, how would that affect the ecosystem. Maybe some animals would die off more, or some would have to much food. Like what if the fly population suddenly doubled, for example, how would that affect the ecosystem? Now what would happen if that organism was removed? If flies were removed, spiders and a lot of other organisms would not have food, and some organisms would overpopulate because nothing would eat them. That is just an example.

Organism: Jaguar
1. Jaguars live in a range of habitats, including arid scrubland, thick tropical forests, swamps, coastal mangroves, lowland river valleys, grasslands, and mixed-conifer forests. They gravitate toward areas near rivers and streams.
2. Habitat loss, wildlife trafficking, collisions with vehicles, and retaliatory killings by landowners and ranchers who fear that jaguars will kill their livestock have significantly lowered the population numbers of jaguars and threaten them with eventual extinction.
3. If jaguars were to go extinct, the number of these animals would perhaps increase, which might change the current ecosystem, from what it is now, to a new ecosystem that will adjust to the species left.
Biome 2: Desert
Organism: Camel
1. No matter the type, camels are usually found in the desert, prairie or steppe. Though many people think that camels only live in hot climates, they do well in temperature ranges from 20 degrees F (minus 29 degrees.
2. The sudden increase in camel populations could be also related to massive import of live animals. The Arabian Peninsula countries are among the main camel importing countries.
3. A mob of feral camels moves across arid land in the Australian Outback. The animals, introduced to the area in the 1800s, are causing enormous damage to the ecosystem. ... Camels also damage salt lake ecosystems, pollute waterholes, and destabilise desert dunes, which can lead to erosion. Meaning There would be less damage to the ecosystem.
