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.

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.

Question :

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.

Why do you sometimes get shocked by static electricity? Explain how it happens and give an example.

Answers

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.

What net force acting on a 14 KG wagon produces an acceleration of 1.5 MS^2?

Answers

Answer:

The wagon exerts a force of 21 Newtons

Explanation:

Force is equal to mass times acceleration, a Newton being 1 kg×m/².  As we're given both the mass and the acceleration, all we need to do is multiply them to find the force applied:

14 kg × 1.5m/s²

= 14 × 1.5 kg × m/s²

Metallic elements usually exist as molecules, combining with atoms of themselves. Metallic elements can exist on their own as individual atoms.

Answers

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.
