How does gravity affect an object?
Answers
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.

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?
Answers
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 mcb of rupa's room is tripped and keeps on tripping again and again . if it is a domestic circuit, what could be the reason of phenomenon?
Answers
The MCB of a rupas room is tripped and keeps on tripping again and again, and if it is a domestic circuit, what could be the reason for this phenomenon?
The reason could be a short circuit which is resulting in higher level of currents to pass through the MCB which is resulting in trip every time.
OR
The MCB is faulty and might need a replacement.
To Diagnose the problem further more.
Turn off all the switches in rupas room and then try turning on the MCB. If it trips again then MCB is faulty (Subjective to the fact there everything was normal before this issue and no signs of short circuit or spark in wiring were observed)
If MCB does not trip in point 1 then Turn ON all the switches one by one. This shall give you the cause of problem.

The kinetic energies of particles in a sample of matter are increasing. This sample is most likely
Answers
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.

Most of the water on Earth is
Answers
Answer:
3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.
To break the numbers down, 96.5% of all the Earth's water is contained within the oceans as salt water, while the remaining 3.5% is freshwater lakes and frozen water locked up in glaciers and the polar ice caps. Of that fresh water, almost all of it takes the form of ice: 69% of it, to be exact.
As these charts and the data table show, the amount of water locked up in ice and snow is only about 1.7 percent of all water on Earth, but the majority of total freshwater on Earth, about 68.7 percent, is held in ice caps and glaciers. Source: Gleick, P. H., 1996: Water resources.
The earth has an abundance of water, but unfortunately, only a small percentage (about 0.3 percent), is even usable by humans. The other 99.7 percent is in the oceans, soils, icecaps, and floating in the atmosphere. Still, much of the 0.3 percent that is useable is unattainable.

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.

Describe the role of plate tectonics for volcanic eruptions, continent formation, seafloor spreading, and mountain formation.
Answers
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!
