How does gravity affect an object?
Answer:
it is a downward force
Explanation:
e.g: keeping humans on earth
Answer:
by gravitational force
Explanation:
The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases. Both objects exert an equal attractive force on each other: a falling object is attracting the Earth with the same size force as the Earth is attracting it.

Why do you sometimes get shocked by static electricity? Explain how it happens and give an example.
Answer:
That tiny shock you feel is a result of the quick movement of these electrons. You can think of a shock as a river of millions of electrons flying through the air. ... Static electricity happens more often during the colder seasons because the air is drier, and it's easier to build up electrons on the skin's surface.

4. Today, farmers breed chickens to have extra-large muscles and to lay of eggs. A wild fowl-a chicken that lives in the woods--lays between 20 and 30 eggs per year. In contrast, a chicken bred by famers can lays many as 300 eggs per year. This idea can be best explained by-
A. Evolution
A. Evolution
B. natural selection
B. natural selection
C. Selective Breeding
C. Selective Breeding
D. Survival of the fittest
D. Survival of the fittest
Answer:
Selective Breeding
Explanation: It's selective breeding because the chicken being breeded by the farmer can produce wayyyyy more eggs.
Which of the answer choices is a true statement? Select all that apply. Nonmetals usually exist as molecules, combining with atoms of themselves. Nonmetals can exist on their own as individual atoms. Metallic elements usually exist as molecules, combining with atoms of themselves. Metallic elements can exist on their own as individual atoms.
Nonmetals usually exist as molecules, combining with atoms of themselves and Metallic elements can exist on their own as individual atoms. therefore the correct options are options A and option D
What is a molecule?The smallest component of a material that still has its content and characteristics is called a molecule. It is constructed of two or more atoms connected by chemical bonds. Moles are the foundation of chemistry. Molecules are designated by their elemental symbol and a subscript denoting their atom count.
Atoms are the fundamental unit of an element. They consist of a nucleus and surrounding electrons. When an atom has an incomplete electron shell, it is said to have valence electrons.
Thus,Metallic elements can exist alone as individual atoms, while nonmetals typically exist as molecules that combine with other atoms of the same type. Therefore, options A and D are the best choices.

Circle the scenario that shows balanced forces and will result in no movement of the gold bar.
Answer :1st one is the scenario that shows balanced forces and will result in no movement of the gold bar. (circled in attachment)Explanation :In the first scenario there are equal forces of 5N acting on both sides of the gold bar, but this is not the case for the second and third scenarios. Equal forces are acting on both sides of the bar in the first scenario, hence showing balanced forces and resulting in no movement of the gold bar.

1. Why is it important for us to know about the changing weather conditions?
2. What kinds of weather can we expect when a cold front is approaching?
Answer:
It's important that we understand how the climate is changing, so that we can prepare for the future. Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperaturesAs the cold front passes, winds become gusty. There is a sudden drop in temperature, and also heavy rain, sometimes with hail, thunder, and lightning.1.It's important that we understand how the climate is changing, so that we can prepare for the future.

The kinetic energies of particles in a sample of matter are increasing. This sample is most likely
Answer:
The sample is most likely gaining thermal energy
Explanation:
If the kinetic energies of particles in a sample of matter are increasing, the sample is a liquid that is warming.
All particles have energy, and the energy varies depending on the temperature of the sample of matter. Solid particles have the least amount of energy, and gas particles have the greatest amount of energy.
The temperature of a substance is a measure of the average kinetic energy of the particles.
If the kinetic energies of particles in a sample of matter are increasing, the sample is a liquid that is warming.

Describe the role of plate tectonics for volcanic eruptions, continent formation, seafloor spreading, and mountain formation.
Answer:
Plate tectonics are responsible for the following events by:-
Explanation:
Plate tectonics are parts of the crust which is moved by the mantle of the Earth.
The Crust is divided into parts called "Tectonic Plates"!
When tectonic plates move they cause some sorts of anomalies, and some of those anomalies are the ones in the question.
When there are two tectonic plates move towards each other, they form mountains, or when wo tectonic plates move away from each other, they cause the sea floor to expand!
Sometimes, they can cause dangerous accidents because of the vibration of the tectonic plates. These vibrations can cause volcanic eruption and tsunamis and Earth quakes.
When these volcanic eruptions occur, they can form underwater volcanoes, and make new islands, which can lead to continent formation!
