Students were investigating how static electricity can cause objects to move. They decided to take pictures of what they observed.Write a scientific explanation about the forces that can affect objects when the objects are not touching. Make a claim and state your evidence.
Answer:
Answer: Think of a thunderstorm, sometimes it depends on the magnitude of a push or pull to move an object even without touching it. When a object is sitting still, it means the normal force and the gravitational force are balanced, when one force becomes greater, it takes over.

Answer:
22
Explanation:
The reason its 22 is because in order to calculate the neutrons of an atom, you subtract the mass and the protons. A potassium atom has 19 protons. This would make the equation 41 - 19 which equals 22.

Minerals like halite and gypsum often form from evaporation. This occurs when.....
1. when water evaporates, some of it turns into minerals if it bumps into rocks on the way up.
2. mineral molecules dissolved in water evaporate with the water, forming tiny mineral crystals in the clouds that fall back to earth when it rains.
3. mineral molecules dissolved in water are left behind when the water evaporates, forming solid crystals.
4. mineral molecules dissolved in water turn solid when the water becomes very hot.
Answer: answer is 4
Explanation:
Rocket engines can be fueled by liquid hydrogen. The liquid hydrogen reacts with liquid oxygen, producing water vapor and releasing an enormous amount of energy.
Consider the following reaction:
2 molecules of hydrogen (H2) react with 1 molecule of oxygen (O2) to produce some amount of water (H2O).
To find the amount of water produced, first determine the number of each type of atom in the products.
Hint: During a chemical reaction, atoms are not created, destroyed, or changed from one chemical element to another.
Answer:
you can check with others I'm sorry I couldn't help tho
What are some possible ways these rocks were formed? Be sure to discuss all 3 rocks.
pls help me
The brownish rock is a sedimentry rock was formed when things like sand, mud, or pebbles get laid down in layers. Eventually the layers are lithified.
The grey rock is a metamorphic rock and was when other rocks are changed because of heat or pressure. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure. They do not melt, but the minerals they contain are changed chemically, forming metamorphic rocks.
The red dots rock is an igneous rock. Igneous rock forms when hot, molten rock crystallizes and solidifies.

How does this simulation demonstrate the Law of Universal Gravitation?
Answer:
The Law of Universal Gravitation states that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them. This simulation uses the sun to attract other planets. The greater the distance between the objects the greater gravitational pull.

Answer:
b. Solid to the gas
Explanation:
Sublimation is the process of transformation directly from the solid phase to the gaseous phase, without passing through an intermediate liquid phase.
Hope this helped!!!
Answer:
Sublimation is the transformation from the solid to the gas phase.
Explanation:
Sublimation is something like for example snow changing to water vapor without melting.
Snow is a solid and water vapor is a gas.

Write a paragraph about the each classification characteristic and how to tell the difference.
Answer:
Square, quadrilateral, rectangle, and a parallelogram
Explanation:
A square has 4 right angles, and 4 parallel sides.
A quadrilateral has 4 sides, and anything with 4 sides is that. A square, rectangle, and a parallelogram qualify as a quadrilateral.
A rectangle has 4 right angle, and 2 pairs of parallel sides. A square is a special type of rectangle.
A parallelogram has only 2 parallel sides, and the angle doesn't matter.
