Variables such as temperature, humidity, pressure, gravity, elevation, vibration, stress, strain, & lighting
Hope this helps

Temperature, humidity, pressure, gravity, altitude, vibration, stress, strain, and illumination are among the variables.

What are precision and accuracy?

Accuracy is the capacity of an instrument to measure the precise value. In other words, it refers to how closely the measured value resembles a reference or genuine value. Small readings can be taken to increase accuracy. The calculation's inaccuracy is decreased by the little reading.

The precision of a material is defined as the degree to which two or more measurements agree with one another. It is incredibly precise but not always accurate to measure something if you weigh it five times and get 3.2 kg each time. Accuracy is not necessary for precision.

The degree to which a measurement is accurate in relation to its real value. The degree to which the same results are produced by repeated measurements under the same circumstances is known as precision.

Therefore, temperature, humidity, pressure, gravity, altitude, vibration, stress, strain, and illumination are among the variables.

The forces from below the surface that change the surface of the earth are

Erosion
Earthquakes
Volcanoes
Living things
Weathering
Faulting
Folding
Glaciers

Answers

Correct! The forces from below the surface that change the surface of the Earth include:

1. Erosion: The process of wearing away the Earth's surface by wind, water, ice, or other geological agents.2. Earthquakes: Sudden movements of the Earth's crust caused by the release of energy in the Earth's interior, resulting in shaking and sometimes surface displacement.3. Volcanoes: Openings in the Earth's crust through which molten rock, gases, and ash erupt onto the surface. Volcanic activity can lead to the formation of new landforms and alteration of existing ones.4. Weathering: The breakdown and alteration of rocks and minerals at or near the Earth's surface due to various physical, chemical, and biological processes.5. Faulting: The movement and displacement of rock layers along a fault line, typically caused by tectonic forces. This can result in the formation of new landforms or changes in the existing ones.6. Folding: The bending or warping of rock layers due to tectonic forces, resulting in the formation of folds and mountain ranges.7. Glaciers: Large masses of ice that slowly move over the Earth's surface, eroding the land and shaping the landscape through processes like plucking and abrasion.8. Living things: While not a direct force from below the surface, living organisms can play a role in shaping the Earth's surface through activities such as burrowing, root growth, and vegetation cover.

These forces, both natural and influenced by living organisms, contribute to the continuous changes in the Earth's surface over time.

1156 g/L
= ________ kg/mL

Answers

The Answer is 0.001156.

To convert g/L to kg/mL, we need to divide the value of g/L by 1000. Therefore:
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.

What happens to the atoms that make up hydrogen fuel as it burns?

Answers

Answer:

When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

Explanation:

When hydrogen fuel burns, its atoms combine with oxygen atoms to form water molecules. So the atoms that make up hydrogen fuel become part of the water molecules.

Through testing and observation, scientists have recorded the following characteristics of Maxoids. Maxoids reproduce via sexual reproduction. One parent carries the Maxoid eggs for 12 weeks before they hatch. After hatching, juvenile Maxoids continue to grow for seven months. To acquire energy for growth, Maxoids consume a peculiar liquid substance native to the planet Moby. The Maxoids' cells use this energy, as well as large amounts of water, to carry out important functions. The Maxoids are sensitive to changes in internal temperature. Sometimes they dig holes and lay in them to cool down if they get too warm.

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

Answer:
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.

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.

Answers

Answer:

1 Sedimentary 2. Metamorphic 3. Igneous (look down for how they are formed)

Explanation:

Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.

Which of the following would occur if the Thrush population was to suddenly decrease?

a
The population of Eagles would increase
b
The population of Eagles would decrease
c
The population of Dragonfly would decrease
d
The population of corn would increase

Answers

Answer- B

Reasoning: Since Eagles directly eat Thrush, their populations would decrease.

The other answers are wrong because with the first choice, Eagles would not increase in population if one of their food sources were removed. For the third choice, Dragonflies wouldn’t increase. Since Thrush eat Dragonflies, the disappearance of Thrush wouldn’t hurt the population of Dragonflies. Lastly, The last option is wrong because corn isn’t reliant on animals to survive. If Thrush disappear, corn will not be affected. This leaves B. to be the answer.

Kinetic energy can never be greater than the potential energy pendulum. A moving object as well as particle has kinetic energy.

What is kinetic energy?

Kinetic energy is a type of power that a moving object or particle possesses. An item accumulates kinetic energy when work, which involves the transfer of energy, being done on it by exerting a net force.

A moving object as well as particle has kinetic energy, which relies on both its mass and its rate of motion. The type of motion might be vibration, rotation on an axis, translation (or travel along a path through one point to another), or indeed any combination of these. Kinetic energy can never be greater than the potential energy pendulum.

Therefore, kinetic energy can never be greater than the potential energy pendulum.
