The unit of charge is.....
Teslas
O volts
joules
coulombs
Answers
Answer:
Coulomb
Explanation:
The unit of charge is coulomb. Electric current is defined as the electric charge per unit time. It can be written as :
\(I=\dfrac{q}{t}\\\\q=I\times t\)
So, the correct option is (D) "coulomb".

Here are a few ideas for a Rube Goldberg machine that closes a fridge door:
A marble rolls down a ramp and hits a small lever.
The lever activates a toy car that rolls down a track and hits a domino.
The domino falls and triggers a chain reaction that results in a weight falling onto a lever.
The lever pulls a string that is attached to a door handle.
The door handle turns and the fridge door closes.

Students are investigating the rocks with fossil markings that are found in an area that was once covered by a lake. The rocks they are observing are MOST likely —
igneous
metamorphic
sedimentary
thermic
Answers
Answer:
sedimentary rock
Explanation:
The rocks they are observing are MOST likely sedimentary. The correct option is C.
What is sedimentary rock?Sedimentary rock is one of the three main types of rock formed on Earth (the others being igneous and metamorphic rocks). It is formed by the accumulation and solidification of sediment, which is any material that is transported by wind, water, or ice, and eventually deposited on the Earth's surface. This can include particles of minerals, rocks, and organic matter.
Over time, these sediments are buried and subjected to pressure and compaction, which causes them to become more tightly packed and solidified. The weight of the overlying layers can also cause the sediment to undergo cementation, where minerals dissolved in water between the particles precipitate and bind them together. As the sediment becomes more compacted and cemented, it eventually becomes a solid rock.
Sedimentary rocks are often characterized by their visible layers or strata, which can contain fossils and provide a record of past environmental conditions. They are also important sources of natural resources, such as coal, oil, and natural gas, as well as many of the minerals and building materials used in construction. Some common examples of sedimentary rocks include sandstone, shale, and limestone.
Here in the question,
Sedimentary rocks are formed from the accumulation and consolidation of sediment, often containing fossils. The fact that the area was once covered by a lake supports the idea that the rocks would have been formed from sediment deposited in the lake. Therefore, option C is the most likely and correct choice.
Igneous rocks are formed from molten magma and do not typically contain fossils. Therefore, option A is not correct.
Metamorphic rocks are formed from preexisting rocks that are altered by heat and pressure. They also typically do not contain fossils. Therefore, option B is not correct.
Thermic is not a commonly used term in geology, so option D is not a valid choice.
Therefore, The correct option is C. sedimentary.

Why is it not possible for lightning to strike the same area twice?
Answers
There's no answer, because there's no question.
It's very highly possible for lightning to strike the same place twice. Or ten times, or a hundred times, or more. Very likely. It happens every day.
Unless the place burns to the ground. Then, it's not too likely that lightning will hit it again after that. But it's still not impossible.
Discuss one component of your school's recycling system that could be automated and predict the economic impact.
Answers
One component of my school's recycling system that could be automated is the sorting of recyclables. Currently, the school relies on students and staff to sort recyclables into the appropriate bins, which can be time-consuming and may result in contamination if materials are not sorted properly.
Automating the sorting process with a machine or conveyor belt system could improve the efficiency and accuracy of the recycling system. It could also potentially reduce labor costs associated with manual sorting.
The economic impact of automating the sorting process would depend on the initial cost of the equipment and any associated installation or maintenance costs. However, over time, the improved efficiency and accuracy of the system could result in cost savings for the school. Additionally, the increased efficiency of the system could potentially lead to increased recycling rates, which could result in cost savings for waste disposal and potentially generate revenue through the sale of recycled materials.
Answer:
Our school has color coded virtual trash cans. For example, a trash can for only paper will only accept paper items, if the item put inside is not paper, it will litter it out and all students have cleaning duties throughout the week so even if you or someone litters you’ll probably have to clean it up at some point anyways. I honestly think it’s very cool. (i wish this was true smh).

List an example of matter in each of the three states.
Answers
The example of matter in the three states is brick in solid state, water in liquid state and oxygen gas in gaseous state.
1. Solid: A brick is a solid object that maintains a fixed shape and volume.
2. Liquid: A glass of water is a liquid that conforms to the shape of its container but maintains a definite volume.
3. Gas: Oxygen gas in the atmosphere is a gas that does not have a fixed shape or volume, filling the available space.
The three states of matter are solid, liquid, and gas. Solids have a fixed shape and volume, such as an ice cube. Liquids have a definite volume but take the shape of their container, like water. Gases have neither a fixed shape nor volume and fill the entire space available to them, such as the air we breathe.
In summary, the states of matter describe the physical properties of substances based on the arrangement and movement of their particles, with solids having a fixed shape, liquids taking the shape of their container, and gases being free-flowing and filling all available space.

Solid: An object that keeps a constant shape and volume is a brick.
Thus, Liquid: A glass of water is a liquid that keeps a consistent volume while taking on the shape of its container. Gas: Oxygen gas fills the available space in the atmosphere and does not have a defined shape or volume.
Gas, liquid, and solid matter can exist in any combination. Solids, like an ice cube, have a set shape and volume.
Like water, liquids have a set capacity but adopt the shape of their container. Gases, like the air we breathe, have neither a set shape nor volume and fill all available space.
Thus, Solid: An object that keeps a constant shape and volume is a brick.

what are two ways erosion affects California land
Answers
Answer:
Two ways erosion affects California land are rising sea levels and soil erosion. Rising Sea Levels can cause homes to go under water and soil erosion can cause the ground to not be harvestable.
Explanation:
Erosions can have a huge effect on many things consisting in California.
Answer:
Water pollution and increased runoff
Explanation:
Erosion can cause soil infected with fertilisers, pesticides, ets. can travel to water bodies, causing that water to be polluted.
Erosion can send particles to block pores in the ground, "patching up" the ground, letting water stay on the ground instead of seeping underground, eventually leading to runoff.

1. In Physics, we distinguish between wave motion and particle motion Wave motion
refers to the movement of a wave-like pattern from one location on the medium to
another. When you view a water wave moving along the surface of water, you are
observing wave motion. There is a very obvious movement of a collection of crests and
troughs along the water surface. In the Simple Wave Simulator, there is a collection of
crests and troughs moving through a rope this is wave motion. But there are also three
points on the rope that are colored red. When you observe the motion of these points.
you are observing particle motion - the motion of particles of the rope. Describe the
motion of these particles.
Answers
Answer:
Look at explanation
Explanation:
One of the easier ways to define wave motion is the continuous movement of particles. When we have a rope for example and whip it, the first particle bumps into the second one then into the third and so on and so forth until the end of the rope. Particles can only move up and down or left and right and the vibration caused by each particle is what sets off the wave motion.
